2 Preparation

2.1 Tools and Equipments

A Pulley of the correct Safe Working Load (SWL), for the load to be lifted must be used and must be

of high quality; with SWL clearly marked on the pulley. (Snatch or closed Pulley block is acceptable).

Typically this will be rated at least 3x the load that will be lifted. Huawei Subcontractor must use

2000kg SWL as a minimum. The pulley shall be in good serviceable condition and fit for purpose

and visually checked before each use. Any obvious signs of damage or over use and the Pulley must

be replaced for the same type.

Only Manual Hand Winches are to be used and this must have a load capacity suitable for the load

to be lifted and must be in a serviceable condition. Typically this will be rated at 3x the load to be

lifted. Hand winches factory certified and complete with the correct leg mounting brackets (2000Kg

SWL).

For extra safety a 2000Kg nylon sling will be wrapped around the winch Leg brackets and fixed with

an appropriate Bow or D shackle (SWL 2000Kg - not tied). In addition to the above, the Operator

must be fully trained and experienced in the use of the hand winch and the rigging work must be

properly supervised by qualified And certified engineers at all times

The number of turns of wire rope on the drum should be a minimum of 4 turns and the Operator

Must be wearing good quality leather gloves and shall keep his hands away from the Winch

When in operation at all times.

Steel Wire Rope minimum 160m, 14mm in diameter with the factory pressed eye thumbnails (no

bulldog or other type of clips is to be used). Huawei teams will only use factory certified and tested



Steel wire rope with pressed eye thumbnails as below,.

Huawei subcontractor rigging teams will not use or are not permitted to use Kernmantle ropes or

any other type of synthetic ropes for Rigging/lifting activities, the only ropes to be used are Tag

line (holding out) ropes.

Tag Lines will be 14 16mm polypropylene or equivalent min SWL 200Kg (none stretch).

Wire Rope / Steel Bond - 12/14mm Factory pressed eye ends.

Rigging attachment devices, such as Webbing slings, Shackles and Carabiners will also be required

and these should have a minimum SWL capability of 2000kg, the same as the other lifting items,

typically 3x the load to be lifted. All items shall be in good serviceable condition and fit for

purpose and visually checked before each use, any none conforming items must be replaced for

new serviceable items..

Radio Transceivers (Back to back Radios/Walkie Talkies) are to be used at all times for

communicating between ground crew and workers aloft. Use of Mobile phones is not

recommended.

General Hand tools, Ratchet socket wrench, wrenches, open ended spanners, water pass etc, are

required & must be fully fit for purpose and must be in good serviceable condition, tools must be

stored in tool boxes. All rigging engineers are to ensure that all hand tools are tethered (tied) to

their harness and canvas flapped (closed) tool bags used at all times when working at height.

2.2 Site Safety - Demarcation of working areas and Drop Zones.

The teams on site must attach Barricade Tape and place safety signs on and around the working

areas, as well as clearly identify the rigging drop zones (half the working height) these areas must

be taped and cordoned off, site access gates must be locked and secured when the rigging work is

ongoing & all engineers are made fully aware of the site safety emergency gathering area in case of

any sudden incidents/accidents.

Safety signs must include the below information:

1. Hard hat Area. (Boots, Hat, Harness, Gloves & Glasses).

2. Personal protective equipment area.

3. Emergency Call information / telephone numbers and emergency contact numbers:

4. No Access to the Public / Local community.

5. Danger men working overhead / at Heights.

Site barricading:

Red and white or yellow and Black cordon tapes can be used for marking out safety areas..

All sites must be taped off to mark the working area and the drop zones; the barricade tape must block the

access areas and be placed at a height of 1.5m AGL.



2.3 Site Worker Preparation

Work Safety Analysis:

A complete Safety Analysis is to be carried out and analyze the risks of the specific site and the

activities of the rigging & planned installation work.

The process is to simply indentify the possible site dangers / risks and the probability or likely hood

of any occurrence due to the identified site risks, the TL must then measure the risks severities and

clearly instruct the team members on how to control all site risks and place tape or cordons around

any of the identified risk areas and brief the team in them all.

Tools box talk:

Each site Team Leader must hold a site installation tools box talk with all members on site, the TL

must fully explain all of the work activities and all engineers informed of their individual roles &

responsibilities be clearly defined.

All member of the team are to be briefed in the first aid and site accident procedures and be made

fully aware of the contact call numbers in case of any incidents, all near misses are to be recorded

and reported as they occur.

Tools box talk contents:

Visual checking analysis of tower or structure condition, site condition safe from danger animals

such as snakes, bees, monkeys etc, First Aid kit check.

Documentation check and brief on the installation requirements is needed. Safety brief, tools

checking, Installation tools checks, Job Arrangements, Rigging tools checking such as Pulley, Sling,

Webbing, Full body harness, all TB talk results logged and recorded.

Engineer Certification check:

Huawei identity Pass & ID as well as WAH Certificatation must be checked: All members of the

team should carry their WAH certification (Copy) with them on all site installations, they must be

fully trained at WAH and HSE by Huawei expert, and all Riggers must hold WAH Certificate from

Menakertrans / Professional Consultant, any persons found to be on site working without the

correct certification will be immediately removed from site and their photo taken, details logged

and reported to the HSE HW manager.



3.0 Knots, Bends and Hitches

All rigging team personnel shall be proficient in and capable of tying the basic rigging Knots, Bends

and Hitches and be knowledgeable in their correct use. Knot tying is only applicable to the Tag lines

and all equipment that is to be lifted is attached with sling and shackle not tied in any way.

The following Knots Bends and Hitches apply and are to be used for the purpose described below

only, no other types of knots are to be used or attempted:

Reef Knot (for joining ropes together)

Clove Hitch (for securing NOT Lifting)

Double Sheet Bend (Lifting)

Bowline (Preferred Knot - Secure safe lifting easy to untie).



4 Drop Zones, Safe working areas and emergency rendezvous areas:

4.1 Drop Zones:

The drop zone is 50% of the actual Working height, or the actual location of the installation.

Example: If the team is working at 30m height the drop zone then becomes 15m from tower base

to surrounding area.

4.2 Safe working areas:

If there are residents living or in the vicinity of the Working Drop Zone Area, inform them about the

dangers and risks involved, ensure safety arrangements are in place & tape off the the drop zone

working area, placing signs around the boundary..

4.3 Emergency Rendezvous Point:

The Team leader must chose a safe area of the site or immediate surrounding area as an

emergency gathering location for the whole team to use in case of any accidents occurring.

In case of any accident occurring or very bad weather, i.e. lightening, hard rain, all work must stop

immediately, climbers must return to ground level and wait in the safe area until the immediate

risks have been addressed or removed or the adverse weather has passed and cleared.

4.4 Site Visitors/ Inspectors:

In the case of any persons visiting the site or trying to gain access to the site whilst the work is

being undertaken, the team leader must ask the persons to wait outside the working area outside

of the cordoned off drop zone. The tea, leader must challenge the visitor for their I.D then allow

to enter site, only fully trained persons are to enter sites, they must show their professional

credentials & certification, TL must report all visitors to the HW RPM



5 Basic Lifting Processes

Before any Lifting starts, the Team Leader must make sure that the Job Safety Analysis, safety sign

and barricade tape, emergency call and Tool box safety talk safety is completed.

Print out the plan or approved method of procedure (MOP, TSSR etc) and follow the plans and

make sure all team members who are involved in the lifting activity fully understand their roles, the

plan and the approved procedures. There must be 1 Team Leader/Supervisor assigned to the site

installation, he/she is fully responsible for making sure all activities run smoothly and as planned.

Test lifts, Lift slowly under control, communicate the lift progress and stop slowly when at the

correct height. Fully check & Ensure all wire rope and blocks are running freely and not snagging or

rubbing in any way possible, if there is any rubbing or snagging of the lifting line found the TL must

re route the lines and ensure that the lines are free from hindrance free pulley blocks and lines at

all times when under stress...

Stop the activity slowly & under control for any issues that arise or that cause concern, check them

thoroughly and then proceed under control with one engineer climbing with the lift in his vision

and manage the lift until it is in the correct landing position on the structure..

6 Lifting Techniques (in Brief).

Ensure the pulley blocks are secured firmly and correctly in the tower leg, not bracings.

The Wire rope is free from any friction and rubbing and wrapped on the winch correctly (4

turns).

Let Taglines run freely under control, avoid any damage to equipment on the tower

No member below the lift Antenna /communicate well with winch controller.

Lift slowly and stop slowly under control at all times, follow the lift & climb as it rises.

Use double pulley to lift the Antenna / safety and back up.

Install blocks/pulley horizontally across the tower face.

Mark the drop zone at location and barricade off.

Stop at the correct height and lock of all winches and tag lines. (Secure the lift/make safe.).

Square Rigging Pulleys and Line

Note: Installation Pulley to tower leg, the structure must be free from corrosion, strong and firm

and then the pulley blocks attached with Nylon slings and shackles.



Pulley Block Placement:

All Pulley Blocks must be attach to the structures correctly by using webbing nylon slings and

shackle SWL 2000Kg. Pulley Blocks must be attached on the Leg & placed above a horizontal

bracing to prevent any slippage or displacement/movement of the pulley under stress.

6 Lifting Test & rigging checks.

6.1 SITE Process and Pre-Lifting checks.

1. Prepare all Lifting equipment and carry out the

Tool box talk, inform the team again for the

Plan of installation ensure all understand their

part clearly.

Team Tool Box talk briefing.

2. Attach the hand winch to the tower leg

Using the manufacturers winch mounting

bracket and a webbing sling for extra safety.

All Leg brackets must be factory, welded and

Installed correctly prior any lift testing taking

Place.

Lifting continued:



3. Attach two pulley blocks in parallel at the

Relevant working height by using the above

Attachment Techniques double pulley blocks

Are used and must be serviceable and fit for

Purpose, installed horizontally and handled &

managed with respect. Pulley blocks must sit

flush and be free of snags and any potential

Interference, all engineers MUST NOT rest their

hands arms or and tools on the wire ropes as lifting

is taking place.

The rigging engineers must keep a Safe working

distance of 1.5m when pulley blocks are in Service

and lifts are in operation and being made.

4. The antenna assembly is to be checked

thoroughly and all cables are secure and

attached correctly, then Lift the antenna slowly

until max 3m where the assembly is vertical

then stop the lift and carry out a visual check of

the wire rope runs and communicate to the

tower riggers & confirm with them that the

pulleys are running freely.

5. The winch operator must use radio for all

communication the tower riggers, the operators

must be experienced and skilled in the winch

operation and wear the correct PPE at all times.

gloves are to be worn at all times.

The excess wire rope must be managed

correctly and stored on a wire rope drum for

management and protection from any potential

damage.



6. Once the above checks have been completed the

lift can continue, one rigger must climb with the

assembly and ensure that he is in communication

with the winch operator at all times, under no

circumstances whatsoever are any persons to stand

under the load when it is being raised.

7. All antenna assemblies must be attached to the

Tower legs correctly and the brackets and bolts

tightened to the correct torque settings of 30Kn.

8. Install the brackets and check that all flat, spring

washers, bolts and both locking nuts are tightened

using ratchet spanners/sockets NOT open ended

spanners as this can round of the nut. The Bolts

must protrude equally and not be twisted or

Mis-aligned in any way.

9. Make sure that the Antenna is aligned to 0 degrees

and according Azimuth plan found in the approved

site installation designs.



10. On completion of all antenna lifting Lifting and the

Antenna installation is finished, the Team leader

Must carry out a full and detailed do self inspection.

To fully check all aspects of the site installation. All

Aspects of the installation are the be in line with

the approved site designs and immediate

rectification made to any none conformances

found.

11. Site De-Rigging must be carried out in a controlled

and disciplined way, under NO circumstances are

any ropes, Pulleys, shackles etc, to be dropped or

thrown to the ground, all equipment and tools are

to be lowered to the ground in a controlled and

safe manner, all tools and equipment must be packed

and stored away correctly and Site clearing must

be made and the site left clean, tidy and secure.

No burning of any waste is to take place on any site

installation.

12. Tag Line Techniques:

Tag Lines or Holding out ropes are to be securely fastened to the antenna assembly and the far end

attached to a stable and load bearing structure (fence post, tree or equivalent), a 2000kg sling

wrapped around and Choked through itself, two 2000kg Bow shackles are then attached to the

sling loop and the Tag line fed through the shackle over itself. When lifting is in progress the

engineer simply feeds the Tag line through he shackle, the line is to be controlled carefully and

never held tight.

Tag Line Sling in Place Tag Line in Operation



7 Mechanical Tilting Procedures

If antenna installed at the rake leg, mechanical tilt

Must adjust until the antenna 0 degree.

1. Loosen the bolt (red marking)

2. Adjust the bolt (red marking) in the bracket

until antenna 0 degree

Once the bolts have been adjusted and the rake

compensated for and the antenna leveled off and

Antenna finally Installed on the tower rake / leg of the

tower the antenna must be set at 0 degrees position.

All bolts and brackets must be tightened correctly and

no washers or locking nuts missing.

8 Azimuth Adjustments

The complete antenna pole with RRU, filter

and junction box will be rotated together, azimuth

adjustment is around +/- 45degree

2 person needed to loosen the antenna pole 2.One for the upper clamp

and one for the lower clamp

Rotate the Antenna, RRU, Filter

To a propose azimuth and lock off

the antenna system



9 Processes for Installation of the Leg Stiffening Mounting

On a 4 legged SST where the tower leg size is lower then 70mm, the antenna triple band

must be installed once the Tower leg has been stiffened. The rigging and lifting process is

the exact same process as described above, the overall lifting procedures are the same

with the lifting of the antenna (compact type 1), and the only difference being the tower

Leg must be stiffened first then the antenna system can be installed not until.

Ensure the pulley blocks are secured firmly and correctly in the tower leg, not bracings.

The Wire rope is free from any friction and rubbing and wrapped on the winch correctly (4

turns).

Let Taglines run freely under control, avoid any damage to equipment on the tower

No member below the lift Antenna /communicate well with winch controller.
