Abstract:
A self-contained hydraulic system used with lifting mechanisms to aid in the lifting of their arms before undertaking lifting operations. The system includes a hydraulic reservoir for a liquid and a gas that share the space under pressurized conditions. A hydraulic control assembly regulates flow through the outlet of the reservoir to use from a hydraulic assembly used to lift the arm of a lifting mechanism. The hydraulic control assembly includes two normally closed, electrically activated valves, connected in series. One of them being unidirectional and including a bypass valve to graduate the flow and thus the speed at which the lifting arm moves. Optionally, a flow fuse valve can be used to limit the maximum flow through the system.
