These hand-hydraulic and pneumatic-hydraulic combined pit jacks / axle and
transmission jacks are lifting devices for lifting vehicles and vehicle
components. The pit jack can be moved longitudinally and transversely via a
carriage, the axle and gear jack via a floor-running carriage with rollers.
An attached support claw serves as a load carrying device. For special load
application points on vehicles, other suitable supports from our range of
accessories can be fitted (support plate, transmission plate, axle traverse).
The hydraulic block contains load, suction and overload valves. The self-closing
lowering screw is also mounted on the hydraulic block. An overflow system is
installed for automatic bleeding.
Special features of manually operated jacks (hand-hydraulic):
The high-pressure and low-pressure hand pumps are mounted according to the
spare parts list, depending on the type (see www.maha.de/de/support).
Compared to the high-pressure hand pump, the low-pressure hand pump has a
larger pump cross-section and thus a larger delivery volume.
Due to its smaller pump cross-section, the high-pressure hand pump has the
ability to achieve higher hydraulic pressures and thus lift heavy loads.
Special features of automatically operated jacks (pneumatic-hydraulic):
In pneumatic-hydraulic pit jacks with rapid control, the hydraulic oil in the tank is
pressurized by compressed air. This displaces the hydraulic oil and the lifting
piston quickly reaches the load application.
The air motor (LM) is an oscillating pneumatic-hydraulic pressure intensifier,
which is firmly bolted to the hydraulic block. It is driven by compressed air and
transports the hydraulic oil.
2.2 Service Life
The product is designed for 22,000 load cycles as standard in accordance with
EN 1493. The duration of the intended use in relation to the possible product
service life must be assessed and determined by an expert during the annual
equipment inspection.
