Self-propelled mobile equipment

The weak link in this system was often the method of secondary transportation located immediately behind the continuous miner. The high rate of advance and loading of the mining equipment meant that normal secondary haulage systems were inadequate and mobile belt conveyors had to be introduced. These high-capacity conveyors have self-propelled drive and tail sections and sufficient belt storage to permit advances of up to 100 ft (30.5 m) without stopping the conveyor. 

The EU Directive 95/63/EC, the Amending Directive to the Use of Work Equipment Directive (AUWED), lays down wide-ranging requirements for the provision, management and use of mobile, self-propelled and remote-controlled work equipment, inspection of work equipment, provision and use of lifting equipment, and the management of lifting operations. 

Mobile equipment would normally move on wheels, tracks, rollers, skids, etc. Mobile equipment may be self-propelled, towed or remote controlled and may incorporate attachments. Pedestrian controlled work equipment, such as lawn mowers, is not covered by Part III. 

In particular, OSHA proposed to exclude from coverage surfaces that are an integral part of self-propelled motorized mobile equipment other than platforms lifted by powered industrial trucks.
