Wheel brakes
Main features:
These brakes are devoted to parking utilization, securing
the crane, in stowed condition, against the wind force, therefore,
in their normal
utilization they have to be closed when the crane is completely
stopped.
In emergency condition they can be operated also as dynamic brakes
to stop the crane. The braking shoes, pressing on the two sides
of
a wheel, are actuated by springs and released by hydraulic power.
Rima wheel brakes are conceived for heavy duty
applications where a high number opening cycles per day is requested.
