•
lift more than one axle at the same time
•
to step onto or ride on the load handling attachment
•
use the jack for other lifting work
•
use additional lifting gear for lifting

4 Machine description
The pit jacks described here are not used on their own, but always in
combination with corresponding chassis.
DIN EN 1494 distinguishes between pit jacks that can be moved in working pits
on rails or on the pit floor and may only be moved without a load, and geared
jacks that can also be moved when loaded and whose direction of travel is not
restricted.
The pit jacks can be combined with different chassis within the limits of a
sensible workflow and what is technically feasible.
There are basically three types of chassis. In addition to three types each of
suspended and rail-guided chassis, the freely movable chassis is available for
moving on the hall floor when used as a gearbox lift.
Suspended and rail-guided chassis can be moved along the guides - rails on the
pit floor or profiles on the pit edge. In the chassis, the pit jacks can be moved
between the left and right edges of the pit.
As the freely movable chassis is already movable in all directions thanks to four
swivel rollers, the pit jack is permanently mounted on this chassis.
Basically, each jack consists of a drive, hydraulic block, oil tank and cylinder.
The pit jacks are divided into single-stage, two-stage and three-stage,
depending on the number of cylinder stages, and into manual-hydraulic,
pneumatic-hydraulic and electro-hydraulic drive types.
Manual hydraulic pit jacks are equipped with a high-pressure or low-pressure
hand pump, depending on the required load. The low-pressure hand pump has a
larger pump cross-section and therefore a larger delivery volume. Due to its
