Presentation about Responsibilities of Lifting Engineer and Safe Lifting Regards: Engr Syed Imran shah

Introduction The role of the lifting team, which includes the lifting Engineer, crane operator, rigger and signalman, is crucial to ensure safe lifting activities at workplaces. Many of past accidents had shown that proper planning, co-ordination and supervision of the lifting work could have prevented the accidents and the needless loss of lives. In particular , the role of the lifting Engineer & supervisor is key especially given the collaborative nature of the work and the importance of ensuring that The various parties are trained and competent, and that they carry out their roles safely and effectively. this presentation will not only provides you the roles and responsibilities of lifting Engineer & Supervisor but also information on common hazards associated with lifting, Lifting Plans, Risk Assessment (RA), Permit-to-Work (PTW) System and Safe Work Procedures (SWP ),

Skills , interests and qualities As a lift engineer, you will need : An understanding of engineering drawings and principles S kills in electrical and/or mechanical work E xcellent problem-solving skills Good communication and customer care skills G ood organizational skills to plan workloads T he ability to work without close supervision IT skills for updating records and writing reports F amiliarity with CAD packages if involved in design work A willingness to work flexibly A n awareness of industry guidelines on health and safety

Common Systemic Lapses Involving Lifting Activities Accidents involving lifting activities occur due to many reasons. However, investigations into such accidents often reveal that the primary causes could be attributed to poor planning, supervision and co-ordination of the lifting operations Absence or lack of RA prior to lifting operation . Lack of implementation of relevant control measures identified in RA . Absence or lack of proper Lifting Plan for each lifting operation . Absence or lack of a PTW system to manage the lifting operation . Failure to adopt a proper rigging method for the lifting operation . Poor maintenance of lifting equipment (e.g., safety devices, lifting gears ). And many more

Responsibilities of Lifting Engineer & Supervisor Planning and coordination of lifting operation Early preliminary study and budgeting for heavy lifting projects Developing detailed lifting and load out plans : cranes selection and working circumstances, rigging study. Lifting lugs and lifting beams design and other steel structure design. Calculating GBP, C.O.G. and weight theoretically and physically using synchronous hydraulic jacks systems Assembly and dismantling of heavy cranes according to manufacturer manual. Supervising execution of heavy lifting and load out operations. Attending heavy lifting meetings both internally and externally with direct client interface.

Responsibilities of Lifting Engineer & Supervisor Inspection of cranes and lifting equipment as they are delivered to site, including inspection of certificates, maintenance records etc. Provide technical support to project manager as well as to lifting supervisors. Developing complete drawings and technical documents and calculation sheets ensuring that the ground conditions are safe for any lifting operation to be performed by mobile cranes ; be present during all lifting operations; and if unsafe conditions are reported to him, to take suitable measures to rectify the conditions so that the lifting operation can be conducted safely.

Common Hazards Associated with Unsecured/ Slippage of Loads Many accidents occurred due to unsecured loads or loads that slipped off during lifting. The following are some common hazards associated with lifting of loads : defective or damaged lifting gears such as slings, hooks, inserts, eyes, shackles ; improper rigging of loads ; lack of proper receptacles for loose loads such as bricks; or under capacity of lifting gears.

Risk Assessment and Permit-to-Work Hazard Identification Risk Evaluation Risk Control Permit-to-Work (PTW) System is a system to manage and control certain types of hazardous work including lifting operations. The contractor’s supervisor coordinating the lifting operation is to apply for the PTW to carry out the lifting operation. In the application for PTW, he should state the scope and conditions in which the lifting operation is to be carried out. An independent inspection is then conducted on-site to verify that appropriate control measures have been taken to mitigate any foreseeable risks. After confirming that the measures have indeed been taken, the application would then be approved by an authorized person. etc

Pre-use Inspection of Lifting Equipment Lifting Engineer must ensure that the crane operator conduct pre-use inspection before each lifting operation to ensure that the equipment is suitable, safe and correctly installed for the lifting operation. The pre-use checks must include : visual inspection of the lifting equipment ; functional test of the lifting equipment ; functional test of the safety system and devices; and functional test of the emergency stop device . Lifting gears must also be inspected to ensure that they are free of any faults or defects before any lifting operation can begin. Lifting supervisor must not allow the lifting operation to be carried out if any defects are spotted during the pre-use checks by the crane operator until all the faults of the cranes are fully rectified. Similarly, lifting gears must not be used if defects are spotted and reported by the riggers.

Pre-use Inspection of Lifting Equipment An authorized examiner must also be engaged to inspect the lifting equipment: After modification or repairs of its load bearing components ; When there is a change in equipment configuration, such as alteration of the boom length or tower crane height; or After an incident or accident involving the lifting equipment .

Selection of Lifting Gears for Lifting Operations Factors affecting the choice of lifting gear for each lifting operation are : Weight and type of load ; Available lifting points ; Position of the centre of gravity of load ; Mode of use Environment factors (e.g., wind speed conditions).

Estimation of Weight of Load The following may be used as a general guidance to estimate the weight of load going to be lifted in the lifting operation . Check if the weight is marked on the load . Check if the weight is indicated on any documentation (e.g., shipping documents ). Check if the weight is indicated on the construction drawing of the load . If the load is still on a trailer or truck, weigh it physically over a bridge .
