Valves Option
The counterbalance valve protects rotation in the event of a hydraulic line failure and protect the actuator against excessive torque loading.
Hydraulic Schematic of Optional Counterbalance Valve.
The counterbalance valve is optional on-demand. SUN brands or other top brands are available for different requests.
Mounting Type
Cantilever Mount
The load is mounted to the shaft flange and is supported at only one end of the shaft. Cantilever mounting is not recommended for aerial work platforms or other critical and safety-related applications.
Straddle Mount
The load is supported at both ends of the shaft.
Application
Steering, Boom positioning, Drill positioning, Platform/basket/jib rotation, Conveyor positioning, Davit rotation, Mast/hatch positioning, Access ramp deploy, Attachment rotation, Shotcrete nozzle rotation, Pipe handling, Brush positioning, etc.
