MEM11023
Operate a bridge and gantry crane


Application

This unit of competency defines the skills and knowledge required for the operation of bridge and gantry cranes that are operated from a permanent cabin/control station on the crane in a manufacturing related environment, including a factory, raw material or finished goods store.

While this unit applies to work covered by licensing requirements, it also includes other manufacturing related skills, including integrating crane operations with production, jobbing, maintenance or warehouse operations.

This unit does not cover the bridge and gantry crane types that are controlled from a location remote to a permanent cabin/control station on the crane and that have three or less powered operations, i.e. hoist/raise and lower in one operation and also does not cover the slinging or rigging of loads.

This unit is not recognised by regulators for licensing requirements. In order to satisfy licensing requirements, the imported unit TLILIC3003 Licence to operate a bridge and gantry crane will be required.

Where the selection and use of tools is required unit MEM18001 Use hand tools and unit MEM18002 Use power tools/hand held operations, should also be selected as appropriate.

Foundation Skills

This section describes those required skills (reading, writing, oral communication and numeracy) that are essential to workplace performance in this unit of competency.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.


Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Hazards include one (1) or more of the following:

ground stability (e.g. ground condition or slopes for load placement)

overhead hazards (e.g. powerlines and service pipes)

traffic (e.g. pedestrians, vehicles and plant)

environmental conditions (e.g. dust, wind, lightning and storms)

other specific hazards (e.g. dangerous materials)

Hazard control measures include the following:

the systematic process of eliminating or reducing the risk to personnel and property through the application of controls consistent with appropriate standards

the application of the hierarchy of control, the six-step preference of control measures to manage and control risk:

1. elimination

2. substitution

3. isolation

4. engineering control measures

5. using safe work practices

6. personal protective equipment (PPE)

Appropriate standards include one (1) or more of the following:
