Hunter (Mechanical Handling) has developed a range of electro/hydraulic medium-duty liftables that enable a demountable body to be lowered onto a trolley for transfer to another area. In operation, the vehicle reverses over the liftable (ivhibh is set in the ground), the demountable body's legs are dropped into position and the vehicle is driven away. The liftable is then raised by push-button control until the table supports the demountable body, and the legs are raised. Finally, the body is lowered to ground level onto the trolley.
The push-button control gear is protected against dirt and spray, while the contactors and starters have been designed to withstand half a million operations without maintenance of contact replacement, which would normally be equal to six years of service at 40 operations per hour, eight hours a day. Capacities vary from 1 ton upwards.
The scissor arms are either profiled from heavy plate or from rectangular hollow sections. The rollers are fitted with needle bearings or oil-impregnated bearings to provide a smooth lifting motion. The bottom frame contains braced scissor arms fitted with heavy-duty rollers and is constructed to give a rigid support to the hydraulic ram and scissors-action mechanism. The platform can be supplied with plain steel plate, chequer. plate or roller top as required.
A totally enclosed fan-cooled motor drives a pump which is situated inside the oil reservoir, together with valves, filters and so on. Mains supply is 400 /440V three-phase 50cycle, 220 /380V three-phase 50-cycle or 230/460V threephase 60-cycle.
