Hydraulic emergency operation as per BGR 159
With this additional equipment, the truck crane is equipped with an hydrau-
lic emergency bleed valve in accordance with BGR 159 (4.2.8). This allows
small loads to be transported in case of emergency, e.g. in the event of an
engine failure.

Applications and function
The hydraulic emergency operation BGR 159 enables the
emergency oper-
ation
of the GMK 4100L-1 and the
emergency supply
of another truck crane.
Emergency operation
In emergency operation, you can drive the
main hoist, derricking gear and slewing gear.
The energy source for the crane hydraulics is
a transformer (
1
), which is driven by the car-
rier's hydraulic system in case of
self-suffi-
ciency
or is driven by a hydraulic
external
energy source
in case of an external power
supply.
The hydraulic circuits are switched via the
valves (
3
).
The control lever (
2
) is used to control the
direction of movement and the speed.

Use hydraulic emergency operation only to transport small loads in emer-
gencies. Have the malfunction rectified as soon as possible. Crane opera-
tion in hydraulic emergency operation is prohibited since it is not moni-
tored by the RCL.
