Loadshifting equipment operation
'Loadshifting' generally refers to the operation of front-end loaders, excavators and dozers. Less common forms of loadshifting are the operation of cableways and flying foxes and draglines. Forklift operation is no longer regarded as 'load shifting', but is now High Risk Work. See the Forklift operation page for details on operation of forklifts or order-picking forklifts.
There are seven classes for the operation of loadshifting equipment:
1. Front-end loader / backhoe (Class LB)
Self-propelled wheeled machine with a main structural support designed to carry both a front mounted bucket loading mechanism and a rear-mounted backhoe.
2. Front-end loader (Class LL)
Self-propelled wheeled machine with an integral front mounted bucket-supporting structure and linkage, which loads or excavates through forward motion of the machine, and lifts, transports and discharges material.
3. Front-end loader of the skid steer type (Class LS)
Self-propelled crawler or wheeled machine in which steering is accomplished by skidding or reversing the track or wheels on one side of the machine. Also with an integral front-mounted bucket-supporting structure and linkage, which loads or excavates through forward motion of the machine, and lifts, transports and discharges material.
4. Excavator (Class LE)
Self-propelled crawler or wheeled machine with an upper structure capable of a minimum of 360 degrees rotation, which excavates, elevates, swings and discharges material by the action of a bucket fitted to the boom and arm or telescoping boom, without moving the chassis or undercarriage during any part of the working cycle of the machine.
5. Dozer (Class LZ)
Items of plant composed of wheeled or crawler tractors with a dozer blade mounted at the front-end of the machine.
6. Cableway / flying fox (Class LC)
An arrangement where a wire rope is suspended between two tower structures, on which is supported a carriage or fox from which a load may be suspended. Wire ropes are reeved in an arrangement to allow the carriage or fox to be traversed, and the load raised or lowered.
7. Dragline (Class LD)
A lattice boom crane configuration supporting a bucket or scoop which is thrown outwards, and retrieved through materials by a drag cable arrangement.
