3. Independent hydraulic circuits
Two hydraulic circuits independent of one
another prevent the unintended lowering of the
platform. In the event of a break in a hydraulic
line in one of the hydraulic circuits, the other
hydraulic circuit holds the platform.
4. Pressure limiting valve
The pressure limiting valve prevents overloading
of the hydraulic system. It is factory preset and
may not be adjusted by the operating company.
When overloaded,the platform can no longer be
raised.
5. Line breakage protection in the cylinder
connection
The line-break safety device in the cylinder
connection interrupts the ow if a break occurs in
the hydraulic lines.
6. Deadman control
The deadman control of the machine ensures
that the function is only carried out as long as the
operator holds the respective control pressed on
the control device.
