The SJBEX200 model jacking beam is provided with two pairs of aluminium support blocks and the beam itself features spring loaded flat arms with roller bearings.
When unloaded, these support the weight of the beam, but allow the entire unit to run smoothly along the pit or ramp, but when loaded, they firmly stabilise the unit.
This unit is provided with the optional hook arms.
It's wide lift configuration ultimately means that the SJBEX200 meets the VOSA recommendation for lifting on jacking point.
