This section covers the core safety principles required when operating a non-slewing crane. It focuses on planning lifts, identifying hazards, and following site rules to ensure all lifting activities are carried out safely. Understanding these fundamentals is critical for preventing incidents and meeting VOC requirements.
Stop and discuss the issue with your supervisor.
Anyone can stop a lift.
By using the pre-lift assessment.
Before every lift.
Never.
No, never under any circumstances.
All lifting operations cease ASAP, when the situation with the lift has
been made safe.
Cease the lifting operation ASAP when the lift has been made safe.
Any site hazards that will affect the safe operation of the crane such as:
No.
This section focuses on how to correctly set up and operate a non-slewing crane. It includes understanding how different factors affect crane capacity, how to control loads safely, and how to interpret load charts. These are critical skills for real-world crane operation and assessment.
It de-rates the capacity.
It de-rates the capacity of the crane.
The rated capacity is decreased.
The formula is: 1 to 1 (i.e. 1m deep = 1 metre away from the edge of
trench/embankment).
Have the Dogger/Rigger stand at 90 degrees to the boom in clear view of
the operator to check.
As per manufacturer and site requirements.
As per manufacturers specifications and site rules. Usually raised up high enough to avoid contact with other mobile plant, vehicles and personnel.
Firm, level, flat and smooth ground.
Forward to and to the side of the crane out of its path and in full view of the crane operator.
A minimum of three (3) full turns on the winch drum.
One (1) degree.
The crane’s load chart.
The power should be isolated and/ or if this is not possible the powerlines MUST be insulated.
Always maintain safe clearance distances when working near powerlines.
Personnel MUST seek an exemption from the relevant authority, and where possible, have the electrical power shut off.
Always maintain safe clearance distances when working near powerlines.
Crane boom could spring up and come into contact with the powerlines.
Always maintain safe clearance distances when working near powerlines.
This section covers inspection requirements for cranes and lifting gear. It includes identifying defects, understanding rejection criteria, and maintaining equipment to ensure it remains safe for use. Proper inspection is a key responsibility of all operators.
Must be filled in every time it’s used.

At all times before and after using the slings.
Tag out of service and separate from usable equipment.
This section focuses on slinging techniques, load handling, and the calculations required to lift safely. It includes understanding sling angles, load distribution, and selecting the correct equipment. These concepts are essential for dogging and rigging competency.

Chock it to prevent rolling
Double wrap two slings and reeve the eye.
The greater angles between any opposite diagonal sling legs. You can learn more about sling angles from the Voceed Toolbox.
Conduct a test lift to ensure all slinging are tightly secured.
Diameter x Diameter x 8 = SWL
The length of each sling leg is equal to the distance between the two
lifting points (equilateral triangle).
No.
C is the correct answer.
Bow shackle.
25%
No, it is not designed to lift a motor unless rated to do so. Check with the manufacturer for clarification prior to lifting.
1 tonne.
2.4 tonne.
7.8 tonne.
