Abstract: A lifting mechanism has a descending mode including an energy-regeneration mode and a non-energy-regeneration mode. The lifting mechanism includes: a battery, an electric machine, a hydraulic pump, an oil tank, a hydraulic cylinder, a work platform and a flow limiting valve. In the energy-regeneration mode, the hydraulic fluid drives the hydraulic pump to operate as a hydraulic motor, thus in turn driving the electric machine to operate as a generator and charge the battery. In the non-energy-regeneration mode, the flow limiting valve limits the maximum of the descending speed of the work platform. In the present application, the flow limiting valve is used to provide throttling resistance to limit the maximum of the descending speed of the hydraulic fluid, thus in turn defining the maximum of the descending speed of the work platform. Therefore, in the present application, by using the flow limiting valve to define the maximum of the descending speed of the work platform, the safety problem due to an accelerated descent during descending of the work platform may be solved, and thus the safety of the lifting mechanism may be ensured.

Abstract: The invention relates to a method (25) of determining the health status of a hydraulic circuit arrangement comprising at least one hydraulic fluid working machine (2, 3). The health status is determined (29) using at least in part an actual temperature information (12) of the hydraulic circuit arrangement (1) that is compared to an expected temperature information (24) of the hydraulic circuit arrangement (1).

Abstract: According to the present disclosure, a controller includes a base and a continuous sealing layer connected to the base forming an environmentally sealed compartment between the base and a lower surface of the continuous sealing layer. A circuit board is positioned within the compartment, and a rotary knob encoder is positioned on an upper surface of the continuous sealing layer. Movement of the rotary knob encoder is detectable by the circuit board through the continuous sealing layer.

Abstract: According to the present disclosure, a system and method for providing stability control to a machine includes generating a yaw signal at a gyroscope disposed on the machine and receiving the yaw signal at a controller in communication with the gyroscope. The controller is also in communication with a user input that generates control signals for driving at least one plant of the machine. The controller is configured to alter the control signals provided to the at least one plant from the user input based at least in part on the yaw signal.

Abstract: A hydraulic unit includes a driving mechanism whose displacement volume is adjustable to two operational states by means of a position-able adjustment element. The adjustment element can be positioned by a servo piston of a servo unit into a first, initial position and a second, operative position. A first front face and a second front face of the servo piston, which are opposing each other, can be pressurized individually with pressurized hydraulic fluid in order to position the servo piston at either end position of a servo cylinder of the servo unit. The servo piston is of a stepped design thereby forming a ring-shaped damping surface opposing the first front face. In the servo cylinder a ring-shaped shoulder surface is formed opposing the damping surface such that a damping volume is formed in the servo cylinder by the damping surface, the shoulder surface and the servo cylinder.

Abstract: Control device for hydraulic variable displacement pumps operated in an open hydraulic circuit and adjustable in their displacement volume by means of a servo control device. The control device comprises a control piston with two control edges to which pressure can be applied by means of pressurized pressure fluid from a variable displacement pump, the control piston being mounted in a housing so that it shifts longitudinally. The housing of the control piston comprises an inlet for the connection of a high pressure line of a variable displacement pump, an outlet which can be connected to a tank and a servo connection which can be linked to a servo cylinder, whereby a link between the inlet and the servo connection can be made via a first control edge. It is possible to create a link between the servo connection and the outlet via a second control edge.
