RSP Load Handling & Safety Practices 5

Question 1

What condition makes a shackle immediately unserviceable?

Accepted Answer

A bent or distorted pin or bow section

Answer

Bending or distortion of the shackle pin or bow indicates the shackle has been overloaded and the material integrity is compromised, requiring immediate removal from service.

Question 2

What is the maximum angle between two sling legs in a bridle hitch before the rated capacity chart values become unsafe to use?

Accepted Answer

120 degrees included angle

Answer

Most sling manufacturers' rated capacity charts are valid up to a 120-degree included angle; beyond this, leg forces increase dramatically and the sling can fail.

Question 3

A rigger is asked to rig a load using a 'basket hitch' around a pipe. What protective measure is required?

Accepted Answer

Use softeners or edge protectors where the sling contacts the pipe edges

Answer

Sharp or rough edges on loads can cut or abrade slings; softeners or edge protectors must be used to protect the sling and maintain its rated capacity.

Question 4

When a signal person uses the 'dog everything' signal, what must the crane operator do?

Accepted Answer

Secure all crane functions and hold the load in place without further movement

Answer

The 'dog everything' signal means stop and hold — the operator must stop all crane functions and maintain the current position until further signals are given.

Question 5

Which document must a crane operator review before conducting any lift on a job site?

Accepted Answer

The crane's load chart for the specific configuration being used

Answer

The operator must consult the load chart specific to the crane's current configuration (boom length, counterweight, outrigger spread) to determine safe rated capacities.
