Holding Valves
The hydraulic cylinders have holding valves that prevent sudden movement of the cylinder rods
in the event of a hydraulic hose or other hydraulic component failure. In addition, the hydraulic
system has a relief valve to prevent excess strain on the hydraulic components. Both the
cylinder holding valves and the hydraulic relief valve are factory-set and cannot be adjusted.
