    Abstract: A work machine (1) comprises at least one structural element (21), at least one pressure medium operated actuator (22) for establishing at least one operation of the work machine, and at least one detection device (23) to determine the position of the structural element (21) of the work machine. An arrangement for controlling at least one operation of the work machine (1) comprises: a control valve arrangement (24) for controlling the actuator (22), and a control device (25) for controlling the control valve arrangement (24). The control device (25) is adapted to control said control valve arrangement (24) for adjusting the pressure and/or volume flow on the return line of the actuator (22) as dependent on the position of the structural element (21).

    Abstract: A field bus solenoid valve assembly has a sensor for detecting the commencement of an actuation cycle for moving a piston in a cylinder and piston assembly. A position sensor detects an end position of a piston in a cylinder and piston assembly at the end of the actuation cycle. A timer times the elapsed time between the initiation of the actuation cycle of the piston and when the position sensor for detecting an end position detects the piston in its end position at the end of the actuation cycle. A comparator operably connected to a storage device and the sensors for comparing elapsed time from the sensors to a normalized time or profile and a predetermined tolerance boundary in the storage device. An alarm device is actuated if the elapsed time is outside of the set tolerance boundary.

    Abstract: A fluid system includes a loading arm connected to a swivel joint. A counterbalance mechanism is connected between the loading arm and the swivel joint. An adjustment mechanism adjusts the counterbalance force applied by the counterbalance mechanism to the loading arm. The adjustment mechanism includes a guide plate connected to the swivel joint and includes a guide slot and a straight bore guide. A bracket is movably connected to the guide plate and has one or more apertures and a threaded bore guide. Fasteners extend through the guide slot and the one or more apertures to selectively secure the bracket to the guide plate. A lead screw is disposed at least partially within the straight bore guide and the threaded bore guide. Rotation of the lead screw causes the bracket to move along a length of the lead screw and thereby adjust the counterbalance force.

    Abstract: A pump system includes a closed-loop fluid circuit and an open-loop fluid circuit. The closed-loop fluid circuit includes a motor for rotating a first component connected to the closed-loop fluid circuit. A closed-loop pump drives the motor up to a first maximum rotational speed. The open-loop fluid circuit includes an open- loop pump for driving a second component connected to the open-loop fluid circuit. A control circuit includes a control valve for switching the outflow from the open- loop pump. The control valve selectively connects the open-loop pump to the closed-loop fluid circuit and simultaneously disconnects the open-loop pump from the open-loop fluid circuit. When the open-loop pump is connected to the closed- loop circuit, the closed-loop pump and the open-loop pump drive the motor at a second rotational speed greater than the first maximum rotational speed.
