1.5 DESCRIPTION OF THE LIFT
The PONYBENCH-B lift is a machine designed and built for lifting vehicles to the height required to facilitate the
inspection and/or sanding of motorvehicle bodies and is constructed in two versions:
• PONYBENCH BEPLUS: electro-hydraulic lift
• PONYBENCH BPPLUS: pneumatic-hydraulic lift
The PONYBENCH-B consists basically of a mobile welded steel frame raised by means of a single-acting hydraulic
jack which controls a mechanism consisting of two pairs of connecting rods that form the arms of the pantograph
mechanism.The power is supplied by a hydraulic unit that sends the pressurised oil to the lifting jack through a gear
pump.
The two models differ only in the source of power sent to the control unit (compressed air for the PONYBENCH BPPLUS
and electrical current for the PONYBENCH BEPLUS).
