Stormajor Radial Boom Stacker

22 Hydraulic Systems
High specification hydraulic components
with comprehensive filtration
and protection systems
guarantee reliable operation
under any working conditions.
For operation in extreme ambient
temperatures, the hydraulic
system may be provided with an
air blast oil cooler (as illustrated)
or, for low ambient temperatures,
an immersion heater may be provided
within the hydraulic reservoir
to maintain the oil temperature
above a preset lower limit
to avoid cavitation at the pump
caused by high oil viscosity.
