The wheel that described underframe front end is installed is roller, and the wheel that underframe rear end is installed is universal wheel.
During work, when described control pedal is in stress, described control valve is in opening, described control
When pedal processed is in relaxation state, described control valve is closed, and first stretches into by lifting thing bottom jack (as vapour
Car underbody), now, screw block carrier also has one section of space with by lifting thing bottom.Step on control step, discharge gas spring.In gas
In the presence of spring, by pallet upwards jacking until with contact simultaneously self-locking at bottom of car jacking, reach in non-loaded (null
Journey) when the quick purpose reaching.Now, thing (as automobile etc.) (up time can be lifted by the operation requirement raising of existing jack
Pin turns tight handle, presses handle, by pressing handss, the effect of roller etc., so that hydraulic hand-pump is started working, jacking weight).
When work completes, when need to put down by lifting thing, trample control step again, gas spring unlocks, lifted the work of thing
With under, gas spring-compressed, pallet is dropped to bottom surface and is contacted with tray seat that (i.e. gas spring completes a cycle of operation, for next time
Get ready), now, can put down according to a conventional method jack (slow rotate in an anti-clockwise direction handle, opens oil return valve,
Descending jack is to home position)
The beneficial effects of the utility model are:, before raising, only need to step on control skirt, pallet can settle at one go,
Directly withstand automobile chassis to start working, eliminate existing jack idle stroke operationally, substantially increase work efficiency.
