4.Activities (Ref.RMP 02-048-01 Rules for Operation of Mobile Equipment)

4.1.1The operator must always be in his normal position in the driver’s cab. It is prohibited to have arms or legs, or generally any part of the body, protruding from the driver’s cab

4.1.2 It is prohibited to carry any passengers.4.1.3 Make sure that no worker is in the close proximity of the handling operations..4.1.4 Do not allow anybody to come near the working area of the crane or pass

beneath anelevated load.4.1.5Do not carry out operations which exceed the capacities of your crane or

attachments.4.1.9 The crane must at all time adhere to the speed limit of 10 km/h when within

the perimeters of the shaft area4.1.10 Do not maneuver the crane with the boom in the extended position unless

under exceptional circumstances and then with extremecaution, at very low speed and using gentle braking. Ensure that visibility is adequate.

4.1.11Brake gently, never abruptly.4.1.12Do not leave the cab when the crane has a raised load.4.1.13Look where you are going and always make sure you have good visibility along

the route.4.1.14Never drive on the edge of a ditch or steep slope.

4.2 Critical Lifts:4.2.1 A register of critical lifts is maintained by the Maintenance Superintendent4.2.2 A critical lift plan must be written or an existing critical lift plan for the same

job must be review prior to initiating the lift.SAFETY - FIRST, LAST, AND ALWAYS

Page3 of 11




4.2.3 Riggers and crane operators must have input into the plan.

4.3 A lift is determined to be critical if any of the following criteria are met:4.3.1 Multiple crane lifts4.3.2 Lifts over operating facilities where this may endanger personnel4.3.3 Lifts over power lines 4.3.4 Lifts involving personnel cages4.3.5 And any lift at or above 50% of the crane’s capacity

4.4Load Cells:4.4.1 All mobile cranes will be fitted with load cells with the display within the visual

range of the operator. 4.4.2 Portable load cells will be available for overhead cranes to be used when the

weight of the lift is unknown.

4.5 Anti Two-Block:4.5.1All Cranes with the exception of small vehicle mounted cranes (<2 ton capacity)

will have anti two-block devices. 4.5.2The devices will be tested as part of the pre-start inspection.

4.6 Communications:4.6.1 Communications between the crane operator and the rigger is critical. The

primary means of communication is the standard hand signal system which both must be trained in.

4.6.2 When visual contact cannot be maintained, radio communications will be used.

4.6.3A radio channel must be dedicated to crane operations whenever this is to be the means of communication.

4.7 Towing Equipment:4.7.1 Rigging equipment that has been used for towing must never be used for

lifting. To prevent this from happening, all rigging components used for towing will be stored in a common area with proper signage.

4.7.2 In addition, all of this equipment will be painted red and any rigging inspection indicators will be removed.

4.7.3 The Maintenance Superintendent will make quarterly inspections of this equipment to ensure the system is being followed.

4.8 Maintenance and Inspection:4.8.1 Maintenance of the register that contains all site cranes, hoists, rigging

attachments and lifting slings is the responsibility of the Maintenance Superintendent.

4.8.2 Any crane brought to site must have a current test certificate, JHA and a pre-use safety inspection developed from the risk assessment to ensure the crane is fit for purpose.

4.8.3 At a minimum, this inspection must satisfy regulatory and manufacturer requirements for frequency of inspection and physical condition of the machine.

4.8.4Every 12 months thereafter, each crane shall undergo a detailed inspection by a competent third party.

4.8.5 Any defect noted that may affect safety must be addressed before the crane is put back into service.

4.8.6 These certificates and inspection records will be noted in the register and filed by the Maintenance Superintendent.

4.9 Training:4.9.1 Riggers and crane operators must be trained, tested and found competent on

each class of crane they will operate. 4.9.2 To remain qualified, operators must meet the minimum operating times and

frequency indicated in the table below or receive refresher training.

100 t mobile 50 t mobile 25 t mobile25 t

overhead10 t
