13 Tonne lift (double rams) 6.5 Tonne per ram
20 Tonne lift (double rams) 10 Tonne per ram
Covering pit widths from 800 mm - 1200 mm. Sizes outside these dimensions are made to order.
The beam moves on four wheels, which have needle roller bearings to ensure easy movement up and down the length of the pit. Parallel wheels are fitted as standard to suit flat angle pit edges with tapered wheels as an alternative for use on RSC supporting rails. Spring loaded wheels can also be provided, these retract when the jack is under load so locking its position.
A high output air pump complete with delivery valve, pre set overpressure valve and 'dead man' release valve produces the high output flow to the cylinders. The design offers air over oil hydraulic power for advance and retract of the cylinders, this increases unloaded movement. Control is by a single air valve. Up for advance and power lift and down for retract.
The lifting stroke of the hydraulic cylinders is dependent on the depth of the lift to which the beam is fitted and the ground clearance required beneath the vehicle. The stroke typically is 150-200 mm. Top quality using chrome plated rods and the latest seal technology to ensure a long and trouble free life. Lateral movement from 180mm upwards, the maximum width dependent on beam width. Each cylinder is fitted with a safety hose burst valve and 90 degrees movement isolation valve for easy visual confirmation of its position.
