Question 2

What is the generally recommended minimum angle between a sling leg and the horizontal when using a multi-leg sling to prevent excessive loading?

Accepted Answer

30°

Answer

Sling legs should form a minimum angle of 30° with the horizontal; as the angle decreases towards horizontal, the tension in each leg increases significantly and can exceed the sling's rated capacity.

Question 3

What does PUWER 1998 stand for?

Accepted Answer

Provision and Use of Work Equipment Regulations

Answer

PUWER stands for the Provision and Use of Work Equipment Regulations 1998, which set requirements for the suitability, maintenance and use of work equipment.

Question 4

Which factors are most critical when selecting an appropriate crane for a construction lifting task?

Accepted Answer

The maximum load to be lifted and the required lifting radius

Answer

Crane selection must account for the weight of the maximum load and the radius (horizontal distance from crane centre to the load), as these determine the crane's required lifting capacity.

Question 5

What does a test certificate for lifting equipment confirm?

Accepted Answer

The equipment has passed a proof load test and is safe up to its rated capacity

Answer

A test certificate confirms that lifting equipment has been subjected to a proof load test (typically 1.25 to 2 times the SWL) and is structurally sound for use up to its rated safe working load.
