Tandem Lift

services-1

 

Incidents involving mobile crane lifts can lead to deaths and/or severe injuries to workers, as well as extensive damage to property. The complex nature of lifts involving multiple mobile cranes (also called tandem lifts) makes them particularly hazardous.

In order to prevent incidents involving multiple mobile crane lifts, sufficient planning and training are extremely important.

 

 

Objectives

On successful completion of this training program, delegates will:

  • Know how to plan and prepare for work;
  • Demonstrate knowledge of tandem lifting procedures;
  • Confirm requirements for tandem lifting tasks;
  • Conduct risk assessment;
  • Perform tandem lifting;
  • Complete work related documents;
  • Clean up work area.
