boom lifts or cherry pickers wear a properly anchored safety harness
    * workers are licensed when operating boom-type elevating work platforms with a boom length of 11 metres or more.

Figure 9: An example of a boom-type elevating work platform. The safety harness and lanyard assembly are not shown for purposes of clarity. The lanyard should be as short as possible and should be attached directly to the designated anchor point on the EWP, not to the handrail.

Mast climbing work platforms

Mast climbing work platforms are hoists with a working platform that is used to raise workers and material to a temporary working position. They use a drive system mounted on an extendable mast, which may need to be tied to a building under circumstances prescribed by the manufacturer.
Mast climbing work platforms can be set up in either single-mast or multi-mast configurations.
They are generally not suitable for use if the profile of a structure changes at different elevations (for example, if the upper floors of a building 'step' back or balconies protrude from the building).
The erection and dismantling of mast climbing work platforms must be carried out, or be directly supervised, by a person holding an appropriate rigging or scaffolding licence.
Further information on mast climbing work platforms is provided in AS 2550.16 Cranes—Safe Use—Mast climbing work platforms.

Workboxes
A workbox is designed to be supported by a crane, hoist, forklift truck or other mechanical device to provide an elevated work area for persons working from the box. It consists of a platform surrounded by an edge protection system and should be designed in accordance with AS 1418.17 Cranes (including hoists and winches) —Design and construction of workboxes.
Where reasonably practicable, other working platforms, such as an elevating working platform
or scaffold, should be used as an alternative to the workbox.
The safety requirements and considerations include that:
    * the workbox is not suspended over persons
    * the workbox is designed for the task and securely attached to the crane. The workbox, lifting attachments and records should be checked by a competent person before use
    * the workbox is fitted with a suitable anchorage capable of withstanding the fall forces specified in AS/NZS 1891.4 Industrial fall-arrest systems and devices—Selection, use and maintenance. Workers must be attached to the anchorage by a lanyard and harness unless the workbox is fully enclosed
    * workers remain within the workbox while they are being lifted or suspended
    * workers do not enter or leave the workbox when it is suspended (except in an emergency)
    * the crane is fitted
