CPCS Slinger Signaller Operations 2

Question 1

As the included angle between the legs of a two-leg sling increases beyond 90°, what happens to the effective working load limit on each leg?

Accepted Answer

It decreases, placing greater stress on each leg

Answer

As the sling angle increases the tension in each leg rises, effectively reducing the load the sling can safely carry; wide sling angles significantly reduce the working load limit.

Question 2

Which type of lifting accessory is best suited for lifting loads with sharp edges where cutting or abrasion is a concern?

Accepted Answer

Chain sling

Answer

Chain slings are most resistant to damage from sharp edges and abrasion, making them the preferred choice when lifting steel beams or other loads with sharp corners.

Question 3

What information is required to be marked on a sling's identification tag?

Accepted Answer

SWL/WLL, material, size and unique identification

Answer

LOLER requires that lifting accessories carry permanent markings or an identification tag showing their safe working load, material type, size and a unique reference for traceability.

Question 4

When determining the centre of gravity of a load, why is this information critical for the slinger?

Accepted Answer

It ensures the lifting point is directly above the balance point so the load is stable and level

Answer

Positioning the hook directly above the centre of gravity ensures the load hangs level and stable during the lift, preventing dangerous swinging or tilting.

Question 5

A slinger discovers that a sling has kinks, crushed strands or a missing/illegible identification tag. What must they do?

Accepted Answer

Remove it from service immediately and report the defect

Answer

Any sling showing kinks, structural damage or a missing identification tag must be immediately removed from service and reported, as its safe working load can no longer be relied upon.
