You will need to apply for a high risk work licence for the below cranes.
Derrick cranes - CD high risk work licence
A derrick crane is a slewing strut-boom crane with the boom pivoted at the base of a mast which is either guyed (guy-derrick) or held by backstays (stiff-leg derrick) and which is capable of luffing under load.
Portal boom cranes - CP high risk work licence
A portal boom crane is a boom crane or jib crane mounted on a portal frame, which is supported on runways along which the crane may travel.
Non-slewing mobile cranes - CN high risk work licence
This licence is for the operation of a non-slewing mobile crane with a capacity greater than 3 tonnes.
A non-slewing mobile crane is a powered mobile crane that incorporates a boom or jib which does not slew and includes an articulated mobile crane or a locomotive crane but does not include vehicle tow trucks.
In Queensland, until 31 December 2016, a person who holds a non-slewing mobile crane licence (CN) is also permitted to operate a reach stacker without holding an RS licence. From 1 January 2017, the RS HRW licence class must be held for the operation of a reach stacker.
Tower cranes - CT high risk work licence
A tower crane is a jib or boom crane mounted on a tower structure, demountable or permanent, including both horizontal and luffing jib types.
Tower cranes are fixed to the ground on a concrete slab (and sometimes attached to the sides of structures). Tower cranes often give the best combination of height and lifting capacity and are used in the construction of tall buildings. The base is then attached to the mast which gives the crane its height. The mast is attached to the slewing unit (gear and motor) that allows the crane to rotate. On top of the slewing unit there are three main parts which are: the long horizontal jib (working arm), shorter counter-jib, and the operators cab.
The long horizontal jib is the part of the crane that carries the load. The counter-jib carries a counterweight, usually of concrete blocks, while the jib suspends the load to and from the centre of the crane. The crane operator either sits in a cab at the top of the tower or controls the crane by radio remote control from the ground.
Self-erecting tower cranes - CS high risk work licence
A self-erecting tower crane is a type of crane with tower and boom/jib elements that do not dismantle into component sections. Self-erecting tower cranes can be transported between sites as a complete unit. The erection and dismantling process is a fundamental part of the cranes function.
Self-erecting tower cranes lift themselves from the ground or lift an upper, telescoping section using jacks, allowing the next section of the tower to be inserted at ground level or lifted into place by the partially erected crane. Therefore they can be assembled without outside help, and can grow together with the building or structure they are erecting.
