Introduction

  • Lifting is very common in the construction industry as a method for material transfer. Through mechanical means such cranes, lifting equipment and manual handling.
  • The risk of injury can be reduced through training and application of correct lifting & handling techniques.

Improper manual lifting can result in a variety of occupational injuries, i.e. musculoskeletal injuries, cumulative trauma disorders hernia, and most common – back injuries which can even lead to a permanent partial or total disability. Avoidance of these expensive and most often debilitating injuries requires maximum awareness on proper body mechanics and correct lifting techniques.

Basic points in proper lift:

  • Firm grip
  • Back straight
  • Arms & load close to the body
  • Feet apart

  • The tension on sling leg depends on its angle to the load and the weight of the load to be lifted

  • When a multi leg sling is used with the sling legs at an angle, the load (tension) in the individual slings will increase as the angle between the legs becomes greater

Summary

Prior to any lifting operation taking place the following must be performed

  • Assess the lifting task to identify and reduce the risk that may be inherent in the operation
  • Where possible, eliminate the need to carry out the manual handing operation and resort to mechanical lifting operation
  • Where risk is identified, implement mitigation measure to reduce the risk
  • Consideration must be given to weight of the load, location of lifting area, equipments to be use and personnel competency
