positioned 6” or more above the truck approach level, a Lower Opening Bridge (LOB) and possibly an Extended Bridge (EB) option will be needed.

Truck approaches to Speed-Lift may be improved for unloading purposes by raising or lowering low or high points respectively, to correct a slanting or sloping truck. This is especially important when hand pallet jacks or carts are used. Ideally, trucks should be level from side to side and from nose to rear door, or with a slight nose high condition of 6” to 8” or so. Position the Speed-Lift on level or nearly level concrete pavement for best efficiency, greatest safety, and greatest mobility should the lift need to be frequently moved.

ELECTRICAL HOOK-UP

Speed-Lift motors and electrical controls are wired for 230 volt, 3 phase, AC power unless 208 volts or 480 volts is specified. The following amperages are required:

A 30 foot, heavy-duty SO power cord complete with three phase twist-lock sockets and plugs comes with each unit, except for E-Z install inside Speed-Lifts which have 15 foot power cords ready to plug in or hard wire to your on/off switched circuit with breaker or fuse protection. Only professionally qualified persons with proper authorization should work on this electrical hookup.

When positioning the power outlet, seek a location where traffic will not cross over the power cord when the docklift is in use. A switched circuit breaker box or on/off disconnect mounted inside the building, on the side of the door nearest the Speed-Lift unloading position, will permit good outlet positioning. A buried conduit housing the electric power lines may be used with any Speed-Lift which is fixed solidly in one position with ground, slab, surface, post support, or wall-to-floor optional anchors.

Three phase motors may run forward or backward depending upon how they are wired. Before the electrician leaves, check for proper motor rotation by moving the Speed-Lift control handle to raise the lift platform. If the motor runs and the platform rises, the motor is wired properly. If the motor runs but the platform does not lift, the electrician should reverse motor rotation by switching two of the hot wires. Do not move or switch the green ground wire on the “L” shaped plug prong. Always switch off and “lock out” electric power before working on electrical systems. After connecting to the proper electric power, raise the platform and remove the steel shipping block under each cylinder. This will permit the platform to be lowered to the ground.
