摘要： A hydraulic arrangement is provided with at least one pressure accumulator for a hydraulic fluid, a hydraulic cylinder with at least one chamber to which pressure can be applied, a connecting line, on the basis of which the at least one accumulator is connected with the chamber, and a control unit. In order to provide an electronic pipe break safety device, an electronically controlled on-off valve is mounted in the connecting line and coupled for receiving control signals from the control unit, and a signal transmitter, which is coupled for monitoring the pressure in the connecting line is also connected to the control unit. If a pressure drop occurs in the connecting line, a signal change is generated by means of the signal transmitter, whereupon the control unit sends a signal effecting movement of the shut-off valve to its closed position.

摘要： A hydraulic arrangement for braking a trailer comprises a brake line connected between a brake system of a trailer and a trailer brake valve. The trailer brake valve is activated via a first control-pressure line which extends between the brake line and the trailer brake valve and via a second control-pressure line which extends between the trailer brake valve and a control-pressure source and acts in opposition to the pressure imposed on the trailer brake valve by the first control-pressure line. An adjustable pressure-reducing means for controlling the control pressure in the second control-pressure line is arranged in the second control-pressure line. It is proposed to design the control-pressure source as part of a hydraulic control of a brake system of a traction vehicle drawing the trailer and to force the pressure-reducing means mechanically into an open basic position by means of an adjustable prestressing force.

摘要： A loading implement and method of operating a loading implement for the adjustment of a floating condition of a boom of the loading implement. The loading implement includes a hydraulic arrangement for the lifting and lowering of the boom, a hydraulic conveying device, a hydraulic fluid tank, a hydraulic cylinder, a control implement connected to hydraulic supply lines for the control of the hydraulic cylinder, a first and a second hydraulic line connecting the hydraulic cylinder with the fluid tank and equipped with a first and a second selector valve, a lifting side load holding valve and a control unit for switching of the selector valves. In order to permit the activation of a floating condition without the boom being lowered uncontrollably, a sensor signals the position of the boom or the hydraulic cylinder to the control unit, which is configured to cause lowering of the boom and/or the switching into the floating condition as a function of the signal delivered by the sensor.

摘要： A loading machine is disclosed with at least one drive train, with at least one overload protection device for the drive train and with sensors for determining an overload state in the drive train. Critical operating conditions of the loading machine can be determined based on signals from the sensors, such that the load application on the drive train can be influenced in terms of power. The determination of critical operating conditions is implemented by means of a control unit which evaluates the signals from the sensors. When preset threshold values have been attained, the control unit generates control signals for a fuel injection pump, upon which a preventive limitation of the power is initiated.

摘要： An improved hydraulic arrangement is provided for a spring support system. The arrangement comprises a hydraulic cylinder, a hydraulic reservoir, a hydraulic fluid feeder, a hydraulic accumulator, a first control valve between the hydraulic cylinder and the accumulator, a second control valve between the hydraulic cylinder and the hydraulic reservoir as well as an automatic shut-off valve and a controller with a lifting position, a lowering position and a neutral position for the hydraulic cylinder. In order to prevent different pressure loads between the accumulator and the hydraulic cylinder, it is suggested to equalize the pressure between the accumulator and the hydraulic cylinder, without impairing the spring support system or the automatic shut-off valve. Accordingly, the accumulator is suitably connected to a non-return valve and to a flow restrictor or orifice.

摘要： The invention relates to an system for supplying a hydraulic circuit with hydraulic fluid. The system includes a working reservoir and an auxiliary reservoir connected to the working reservoir by a hydraulic line. An air pump has an inlet connected to a suction line that opens into a liquid-free portion of the auxiliary reservoir so that a negative pressure can be built up in the auxiliary reservoir relative to the atmospheric ambient pressure. The air pump inlet is also connected to a control line, which comprises a control opening which is covered by the hydraulic fluid in the working reservoir, at least before the air pump is started up.
