1 INTRODUCTION1.1 BackgroundPT Envitech Perkasa carry out lifting operations to support activities such asconstruction, erection and commissioning. Lifting equipment used includes mobilecranes, winches and lifting gear.

1.2 PurposeThe document provides direction and guidance for all personnel involved in liftingoperation to plan and execute safe and effective lifting operations. This documentdefines procedures for lifting operations and criteria for selecting and using liftingequipment and lifting appliances.

2 LIFTING PROCEDURES2.1 GeneralPreparation of lifting operations shall include the operator, lifting supervisorfollowing the checklist given in Appendix 1 to obtain written authorization fromrelated party or the work site custodian to carry out the lifting operation. Inaddition lifting operations shall be covered by Valid (PTW) Permit to Work and

Access Authorization at locations where these systems operate.

2.2 Lifting planPrior to carrying out any lift a lifting plan shall be discussed and agreed by theequipment operators, riggers, banksmen and any other personnel involved in the

lift. Potential hazards shall be identified and the plan shall identify the means toavoid them.

2.3 Load Balance and StabilityBefore lifting, it is essential to ensure that when clear of the ground, the load willadopt the intended attitude and remain securely attached to "the lifting machine"without overloading any part of the machine and lifting gear. This means that theload must be both balanced and stable.


3/15








2.3.1 BalanceFor most lifts the load is required to be level when clear of the ground. To achievethis, the hook must be positioned vertically above the centre of gravity (C.G) theload.

The legs of the sling(s) should be distributed as evenly as possible according tothe lifting points available. The angle which each leg makes with the verticalaffects the proportion of the load which will be imposed, so all legs should be, asfar as practicable, at the same angle.

If the load tilts on lifting, the loads in the sling legs will be unequal. This effect isespecially significant when the angle between the legs is small.

If a rigid load is lifted on four or more lifting points it may be found that only twoor three legs take the majority of the load with the remaining legs providing arelatively small balance force. If this is the case, larger capacity slings will berequired.

2.3.2 StabilityIn this context, stability means resistance to toppling. An object with a narrowbase and high centre of gravity will need less force to topple it than one with awide base and a low centre of gravity.

As the height of the centre of gravity increases relative to the width of the base, apoint will be reached where the object will fall over unless it is supported byexternal means. At this point, the object is regarded as being unstable. A similarsituation exists with a suspended load.

It is essential when slinging a load to ensure that it is stable. A load will beinherently stable if the lifting gear is attached above the centre of gravity and

properly disposed around it. If the attachment points are below the centre ofgravity the load will be unstable and addition supports or another method ofrigging will be required.

When it is intended to turn over the load in the air or position it at an inclinedattitude, special consideration shall be given to the question of balance andstability to ensure that at all stages of the operation the load remains balanced,stable and securely attached without overloading.

On occasions, particularly when using a single leg sling, it may be necessary to liftthe load such as a pipe or drum with the sling positioned a short distance awayfrom the centre of gravity. In such cases the load, when lifted, will take up a tilted

position but will be inherently stable.


4/15








2.4 The LoadThe load shall be assessed to determine the lifting plan including type of liftingappliance and lifting gear to be used. Assessment shall cover: Whether load is chemical or hazardous material The shape and number of pieces intended to lift at a time Whether load is self supporting or requires additional support Whether load has particular conditions that need to be taken into account i.e.

fragile , hot , cold , corrosive or sharp Compatibility of lifting points with lifting gear. Weight of the load ( This is vital ) Center of gravity of the load before lifting. Whether the load is fixed down or free to lift. If it is fixed, will it be stable

when the fixings are released or will it need support.

2.5 The Lifting Appliance (machine) And Lifting GearLifting appliances shall have a current valid Inspection / Test certificate inaccordance with Client specification.

The lifting appliance shall be positioned above the centre of gravity of the load. Itmust, in particular, be of sufficient Safe Working Load (SWL) and be able to movethe load in a controlled manner to allow positioning.

If a lifting point is to be used to be suitable it must also have sufficient SafeWorking Load (SWL).

Lifting gear shall have been inspected and marked with the current colour code inaccordance with the ralated standard. It must have sufficient SWL to execute thelift.

2.6 The SiteThe site where lifting is to take place, shall be clear of obstructions includingoverhead power lines. Ground conditions shall be suitable to support and travelwith the load (if applicable) There shall be a clear and safe path from the liftingsite to the landing site. The landing site shall be level and strong enough to takethe load. Beware of excessive floor loading, soft ground and hidden weak spotssuch as ducts and drains. Proximity of live process plant and other machinery is aparticular consideration. The landing site may need preparation in which case thisshall be done before the lift commences.


5/15








The lifting plan shall also take account of any environmental factors i.e.temperature, moisture, wind etc. that may affect the operation.

2.7 Procedure for Control of Heavy and Critical Lifts:This clause specifies the minimum requirements to be met for the execution ofheavy & critical lifts. Lifting operations are classed as heavy and / or critical if anyof the following conditions apply.

All lifts exceeding 100 Tonnes All lifts exceeding 75% of the rated capacity of Cranes in as rigged

condition. All lifts requiring use of more than one crane simultaneously. All lifts involving equipment made of thin /fragile members susceptible to

deformation during lifting Lifting in close vicinity of a live plant where lifting operation can endanger

the safety of the plant.

The lifting operation shall be planned and performed taking in account all the

foreseeable risks. As a minimum the lifting plan should include the following:

Verification of crane capacity versus load. Selection of lifting gear suitable for the operation. The characteristics of load and method of rigging for lifting. The position of crane and load, before, during and after the operation. To the scale, sketch shall be prepared, detailing the stages and sequence of

operation. Relevant calculations supporting the safety limits of the operation considering

effects of dynamic loading and weather conditions. Specific instructions for handling of equipment supplied by the manufacturer The ground conditions, and requirements for leveling and compacting, if

necessary Clear identification and defining of responsibilities for various activities. A lifting

team comprising site engineers, Lifting /Rigging superintendent, craneoperator, rigger, banksman and a safety officer is essential for the operation.The crane operator shall not be placed in charge of the lifting operation

The following documents shall be prepared prior to undertaking the operation.1. The Lifting plan covering all aspects of the lift.2. Certificates for cranes, lifting gear, crane operator & riggers

3. Drawings/documents relating to equipment / load to be handled


6/15








2.8 Lifting Tubular GoodsLifting of tubular sections (pipes) is a common lifting operation to which thefollowing guidance notes apply When loading / unloading from a trailer the need for personnel to climb onto

the load to position slings and hooks shall be avoided wherever possible. Thisshall be achieved through use of access platforms and load positioning to allowaccess between the headboard and the load.

Personnel may only access the trailer etc on ladders that are correctly set up. All personnel shall dismount from the trailer after positioning slings and before

lifting commences. Hooks are permitted to connect to the pipe ends only when they are of a type

designed specifically for the purpose. Standard hooks are not acceptable sincethey will be subject to overstressing.

When slings ( without hooks ) are used they should be positioned approx. 25% of total length in from either end

The slings should be doubled wrapped with a choke hitch taking care not tocross over the sling on the underside of the pipe or pipe bundle. The chock

hitch should be pulled tight to secure the bundle. The included angle between the slings shall not exceed 90 degrees. Bundled pipe shall only be lifted using the correct slings designed to handle the

load. Bundling straps shall not be used to lift the load. The slings supplied with pipe bundles from the manufacturer or stockist shall

not be used for any purpose other than lifting of the bundles duringtransportation to the Company designated store or laydown areas. They shallbe scrapped immediately after this use.

3 MOBILE CRANES3.1 Lift Preparations:The crane operator shall be satisfied that site conditions are suitable to executethe lift. He should check the weight of the load against the crane capacity. Theoperator shall assess the radii at which the crane will be required to operateduring the lift and consult the load charts to verify crane capacity to work underthe load/radii combinations. He shall ensure the crane set up has an adequatenumber of wire rope falls to accommodate the load.

All pre-use checks shall be completed and the lifting plan discussed and agreedbetween the crane operator, riggers and banksman.


7/15








Outriggers shall be positioned so the crane is level with the wheels just clear fromground.

The operator shall verify he can receive and send signals to the riggers andbanksman.

Hand signal communication shall be in accordance with standard hand signalrequirement but during the actual lift signals shall be from a single banksmanexcept for the emergency stop signal which may be given by any person.

3.2 Executing the LiftThe operator shall position the hook above the center of the load and ensure theriggers attach the load correctly to the cranes hook.

The operator shall keep the boom angle at 40 degrees or higher during the courseof the lift.Following signals from the rigger, the load shall be hoisted approximately 300mmfrom the ground.

At this point the operator shall cross check the reading on the load indicator withrelevant load chart to ensure the load indicator is operating correctly. The riggersshall check the load to see that it will remain stable.

If it looks unstable the load must be lowered to the ground and additionalsupports added.

If the load is satisfactory, a tag line(s) shall be attached and the load traveled tothe prepared landing site.The operator shall lowers the load to approximately 12 from the ground, when itshall be checked to see whether additional supports are required to land the loadsafely.

The load can then lowered to the ground onto supports if necessary.The rigging tackle can then be removed and the banksmen shall give theshutdown signal. Cranes shall never be utilised for any purpose other than those it was designed

to perform. Mobile cranes shall not be used to transport a load, Mobile cranes shall not be used when the wind conditions are more than 25

knots.

4 HOISTS4.1 Selection of Hoists

Select the correct capacity Equipment of load intend to lift Select the correct and required Height of lift (Range of lift ) If the range of lift is more. Chain block can be used If the range of lift is short. lever hoist can be used Check the Anchoring and attaching point. If you have Runway beam, trolleyas well as chain block can be used. Lack of Head room and confined space Check any obstruction that may impede the operation. Selection electric or pneumatic operated hoist depends on availability of

power source Electric operated machines are hazarded than pneumatic operated. These are all used only for vertical lift. The operator must be trained to operate this kind of machine

4.2 Pre use examination and procedure: Check the required valid Inspection / Test certificate for the particular

equipment Check the general conditions of the equipment Check the safety latch whether it is fitted or missing. If it is missing, dont

use it. Know the operating mechanism of each equipment Check the condition of brakes and other safe locking systems Check the operating levers (Chains, Operating handle. Pawl and ratchet

mechanism) Check there are no sign of misuse (stretched hook, cracked casing anddistorted chains) Stretched hand chain or distorted operating lever could indicate previous

overloading. It is essential to ensure that the structure from which a hoist is suspended

is adequate for the load it is intended to carry.(it includes Hoist itself, Hookattachments, Sling, shackle , trolley etc)

When using hook suspended hoists, the top hook should be attached to itssupports in such a manner that the support fits freely into the seat of thehook and does not exert any side thrust upon the point.

The top hook should be fitted with safety latch.


9/15








After installation, checks should be made to ensure that the hand chain andload chain hang freely and are not twisted or knotted.

The length of the load chain should be checked to ensure that the bottomhook will reach the lowest point required with out running the load chainfully out.

If the load chain is permitted to run fully out, undue stress may be placedon the slack end anchorage (which is not a true load bearing component)

The Operator be familiar with the equipment and the manufacturersinstruction on its operation, maintenance and inspection. Ensure that Load rigging (i.e. Sling, shackles. Ring) correctly bowl of the

hook and allow the safety latch to close. Ensure that the load is correctly balanced Ensure that all restrictions have been removed e.g. hold down bolts The Operators /users must wear the correct Personnel Protective

Equipment (PPE) safety attire, coveralls, safety shoes, hard hat, gloves Use certified lifting loose gear for attachments

DO NOT:

Load the tip of the hook Use the load chain as a sling wrapped around items to be lifted and hooked

back on itself Travel the load above the personnel Use excessive force on the hand chain or operating lever as this would

result in over loading the equipment (chain block , lever hoist) Use the extension pipe on the lever for extra leverage (lever hoist) Never allow the lifting machine unattended with load. Never try to drag the load with lifting machine which is designed for lifting

Never try to lift the load with pulling machine which is designed for pullingonly. Drop and drag the lifting machine on the floor or deck

5 USE OF LIFTING GEAR5.1 Responsibility of RiggersIt is the riggers responsibility to ensure that the Lifting gear is functioningcorrectly, is safe to use, and properly maintained. They shall:

1. Check that the lifting gear is in good condition, certified for use, correctlycolour coded, and of sufficient capacity to carryout the lift


10/15








2. Ensure that Lifting Gear is marked or punched with I.D. Number , SWL andangle of lift

5.2 Selection of Lifting GearSelection of lifting gear shall take account of:

A. Load Characteristics: Size and Weight of the load Physical nature of the load (Chemical ,solid piece , pipe, vessel ,Electrical

Item or machine) Attachments, Lifting points and supports Position of load whether it is vertical or horizontal Height and range of lift

B. Site Characteristics: Temperature Limited space or head room Indoor or outdoor

Refer to Appendices for SWL charts for various sling types, eye bolts and shackles

5.3 ShacklesThere are two types of shackles in general use:

Dee shackle; and Bow shackle.

Selection of shackles: Shackle shall be selected based on weight of the load and number of wires

to be accommodated and or size of hook.

Bow shackles are preferred if a number of wires are to be accommodated Shackles should be selected to suit the load being lifted allowing for any

increased loading due to sling angle. The dimensions of the shackle will often be governed by the hole diameter

and the thickness of the material of the lifting eye. If safety pin shackles are used, ensure split pins are fitted Screw pin shackles are preferred where frequent attaching and detaching

of load Safety pin shackles are preferred where attachment to wire rope or load is

permanent. Load should act on the centre of the pin and crown of body.


11/15








Ensure that the sling eye fits into the body crown The shackle body should be able to swivel to accommodate inclined loads. Never use a shackle in such a manner that it will unscrew the shackle pin. Never replace the shackle pin with bolts Never weld on shackles

5.3.1 Wire Rope SlingsThere are two types of core used in wire rope construction.

Steel core wire rope; and Fibre core wire rope. They can be Single Leg, and Multi-Leg. The end

termination can be soft eye or thimble eye.

Selection and Use of Wire Rope Slings: Select the wire rope based on the weight of load, number of hooks for

attachment, no of items to be lifted at a time. Use of single leg sling is preferred where there is a single point hook or

attachment. Use of multi leg slings is preferred where there are multiple lifting points (i.e.container, ) When using multi leg wire rope slings, included angle plays a major role, the

SWL decreases with increase in angle. Ensure all the legs carry the sameloading

Fibre core wire ropes are preferred where flexibility is required in application Steel core wire ropes are more resistant to crushing l (Winch operation) The wire rope sling shall have current inspection current color code and I.D,

SWL, Angle of lift clearly marked and visible. Select the suitable Effective Work Length (EWL) so that the included angle

does not exceeding 90 degree. Never drag the sling across the floor Never drag sling out from under a load with crane Always use a softener when using the sling against a sharp object. Never repair the wire rope sling (Welding etc) Never knot a wire rope sling Never permit the sling angle exceeding the marked angle on the sling


12/15








5.3.2 Webbing SlingsWebbing slings are versatile and light weight and easy to handle and as such arecommonly used but they are very susceptible to damage during use and if storedincorrectly. .There are two types:

Round webbing sling; and Flat webbing sling (Belt)

Selection and Use of Webbing Slings Webbing sling shall have current colour code and I.D, SWL, Safety factor

clearly marked and visible. Prior to use, Webbing sling should be laid out in good light and examined over

its full length and checked for damaged caused by sharp edged, Burning andscuffing ,contamination by chemicals, and damaged stitching.

Sling shall be selected based on the weight of load and mode of lift (choke orbasket hitch) The mode factor shall be used for calculating the SWL .i.e.straight lift M=1.0, choker hitch M=0.8, basket hitch with 0 degree M=2.0,

basket hitch with 90 degree M=1.4 Generally the width of the flat webbing sling governs the SWL. By thumb rule,

for simplex webbing sling 50 mm equal to 1.0 ton, for duplex webbing sling. 25mm (1 ) equal to 1.0 tonne, 2 equal to 2.0 Ton.

Sharp edges on the object can cause local cuts and tears. Special care shall betaken or use soft packing against sharp edges.

Webbing slings are preferred over other types of sling where the object issusceptible to damage.

Webbing Slings shall never be used in knotted or twisted condition Slings shall never be repaired. A damaged webbing sling or a sling with

damaged cover shall be discarded and taken out of service. All Webbing slings shall be stored away from direct sunlight (to minimise the

effect of ultraviolet deterioration) on a clean rack, away from any source ofheat.

Do not use a webbing sling in conjunction with a wire rope sling due to themismatch in elasticity's.

5.3.3 Eye BoltsEye bolts are commonly used for lifting equipment like motors, panel boards andpumps during maintenance work.


13/15








There are different types of Eye bolts: Dynamo eye bolt; Collar eye bolt; and Collar eye bolt with link.

Dynamo eye bolts are preferred axial loads are applied (Motors, pumps) Collareyebolts and eyebolts with links are preferred where angle of lift is constant, as

the collar and link bears all load.

Selection and Use of Eye Bolts: Eye bolt shall be selected based on the weight of load and female thread on

the equipment, number of lifting points and position of lift (straight orinclined).

Eye bolts shall have current colour code and I.D, SWL clearly marked andvisible.

The thread of eye bolt and thread on the load shall be examined for wear,thread damage, wear on crown and deformation.

SWL reduces as lift angle increases. Eyebolts should always be screwed down tight so that the collar is in full

contact with the surface of the item being lifted. Shim washer shall be used to obtain full contact with the surface. If lifting with a pair of eye bolt, always use a two leg sling with hook , never

use a sling in a basket form Never carry out alterations on eye bolts (welding or threading) Never pull the eye bolt in horizontal direction.

5.3.4 Plate ClampsPlate clamps are available in two designs. Horizontal plate clamp; and Vertical plate clamp

Selection and Use of Plate Clamps: When selecting the clamps consider how the plate is to be transported and

stacked ( i.e. horizontally or vertically) Consider the weight of the plate to be transported which will determine the

SWL of the plate clamps Consider the plate thickness and Jaw opening


14/15








The plate clamp shall have the current colour code, I.D, and SWL clearlymarked and visible.

Check for any obvious defects( Wear or stretch in crown on link, wear on jaw,any mal functioning of locking mechanism)

Position the clamp over the edge of the plate and ensure that plate buttsagainst the jaw stop

Check the plate is clean and free from mill scale , dirt , oil and grease Lock the jaw in the closed position and ensure that the jaw has firm bite onthe plate Use an adequate number of plate clamp to balance the load. Lift slowly to allow the jaw to obtain a good grip. Use a spreader beam to lift heavier plate. Never attach the clamp to the side of the plate Never lower the load fast, it could cause the clamp to release the plate Never lift horizontally with a vertical clamp and vice versa Never lift more than one plate at a time.5.3.5 Beam ClampsBeam clamps provide a simple and portable means of attaching a hoist to arunway beam or lifting beamBeam clamps are available in two basic designs, the Clip on type and morepopular adjustable type

Selection and Use of Beam Clamps: Ensure the correct clamp is selected to suit the beam flange and the weight of

the load to be lifted. The width of the beam flange must also be considered and may well lead to

the selection of clamp in excess of desired SWL to be compatible with thebeam dimensions.

If the clamps are to be used to suspend a sheave block, the additional loadcaused by the down load pull on the effort rope must be taken intoconsideration.

The beam clamp shall have current colour code and I.D, and SWL clearlymarked and visible.

Check the suspension shackle, load bar for wear , stretch, distortion Check the inner and outer clamps for wear ,distortion and cracking and jaws

for deformation Position the beam clamps on the beam flange directly above the load to

minimise the any angular loading.


15/15








Hand tighten the clamp onto the flange by means of the tommy bar andensure it has seated correctly

Over tightening cause undue pressure on the clamp knuckles and can result inthe clamp failing.

Under tightening results in the load being transferred to clamp knuckle and canresult in the clamp failing.

Ensure the hoisting unit is correctly seated in the suspension shackle. Never subject the clamp to side loading Never overload the clamp
