What you will learn & how you will be assessed

To successfully complete this unit, you will need to demonstrate that you can safely sling and direct the movement of loads using a slewing mobile crane.

You will be required to demonstrate your skills with at least five different loads using a slewing mobile crane with a minimum rated capacity of 7 tonnes.

You will be required to:

• Check relevant SWMSs, workplace information and equipment records

• Identify hazards and apply appropriate risk controls

• Determine load weight, centre of gravity and travel path

• Select and inspect suitable lifting gear

• Apply appropriate slinging techniques and calculate WLL deration

• Safely sling and direct loads through at least 180° of the crane's slewing radius

• Use hand signals, whistle signals and two-way radio communication to direct the crane operator

• Use an observer/communication methods when the load is outside the operator's view

• Make temporary connections using fibre or synthetic ropes

• Use required knots and hitches, including single sheet bend, clove hitch, rolling hitch and bowline

• Safely inspect, use, care for and store lifting equipment

The loads must include:

• A stillage containing scaffolding standards or loose steel pipes of 200 kg or more

• Loose steel pipes of at least 2 m length

• An uneven load of at least 2 tonnes

• A steel plate of at least 1.5 m × 2 m × 25 mm

• A round load of at least 300 mm diameter and 3 m length

You must use each of the following at least once:

• Flexible steel wire rope (FSWR) sling

• Synthetic sling

• Chain sling and shortener

• Spreader bar or lifting beam

• Tag line

• Shackles

• Eyebolts

• Plate clamps

You will need knowledge of:

• Dogging safety requirements, legislation, standards and codes of practice

• SWMSs, permits, equipment records and manufacturer requirements

• Hazard identification, risk assessment and hierarchy of controls

• Common dogging hazards, including overhead hazards, traffic, pedestrians, weather and unstable surfaces

• Exclusion zones, traffic controls, fall protection and required PPE

• Hand, whistle and radio signals used to direct crane operations

• Selection, inspection, safe use and limitations of lifting equipment

• Load weight, centre of gravity, stability and destination requirements

• WLL calculations and deration for different slinging techniques

• Slings, shackles, eyebolts, plate clamps, spreader beams and tag lines

• Knots and hitches used for temporary load connections

Assessment will be conducted using a slewing mobile crane with a minimum rated capacity of 7 tonnes, appropriate lifting equipment and the required PPE. You must demonstrate safe and consistent dogging practices while slinging and directing the movement of five different loads in accordance with workplace procedures, manufacturer requirements and relevant WHS requirements.
