摘要： A control device for a working device (12) connected to a hydraulic circuit (10), especially for a load fork (16) which can be raised and lowered with a working cylinder (14) in a fork-lift truck. A valve control unit moves into an adjustment position when the load fork (16) is lowered even when carrying a load (18). A predefinable maximum volume flow is maintained in the hydraulic circuit (10). By providing the valve control unit with a pressure regulator (26) limiting a pilot control pressure for the control valve (28), once a predefinable regulating pressure differential is reached in the hydraulic circuit, the control valve moves into a regulating position to maintain the maximum volume flow. The known flow control valve is replaced in the main flow by a pressure regulator (26) disposed in the pilot control circuit (40), and only needs to be dimensioned for low volume flows. As a result, the control system can be constructed using simple, low-cost components which operate in a functionally reliable manner and enable stable control behavior.
摘要翻译：一种用于连接到液压回路（10）的工作装置（12）的控制装置，特别是用于在叉车中用工作缸（14）升高和下降的负载叉（16）。当负载叉（16）即使承载负载（18）也下降时，阀控制单元移动到调节位置。在液压回路（10）中保持可预定的最大体积流量。通过为阀控制单元提供限制控制阀（28）的先导控制压力的压力调节器（26），一旦在液压回路中达到可预定的调节压差，则控制阀移动到调节位置以保持最大体积流量。已知的流量控制阀通过设置在先导控制电路（40）中的压力调节器（26）在主流中被替换，并且仅需要对于小体积流量进行确定。因此，可以使用以功能可靠的方式操作并且实现稳定的控制行为的简单，低成本的部件来构造控制系统。

摘要： A lift truck having an acceleration sensor and a feedback control system for automatically adjusting the tilt angle of the load supporting surface relative to the lift truck during lift truck operation. The control system maintains the load supporting surface substantially perpendicular to the direction of the resultant of the gravitational force vector and the travel acceleration force vector. The sensor is mounted to the mast for sensing the direction of the resultant vector and is connected as the feedback element of the control system. A controller stores a reference input comprising a stored value of angular direction representing the angular direction of the resultant vector when the lift truck is at rest and the cargo support fork is horizontal. The deviation or error of the control system is the difference between the stored vector direction and the sensed vector direction of the resultant of the two accelerations. The controlled element of the feedback control system, to which the control system output is connected, is the mast tilt actuator of the lift truck. The mast tilt angle relative to the lift truck is controllably varied to bring the currently sensed resultant angular direction into alignment with the stored reference angular direction.

摘要： The present invention is directed to a material handler that includes a frame, a telescoping boom, a boom extension sensor, a boom angle sensor, and a control system. The telescoping boom is coupled to the frame, pivotable between a lowered and a raised position, and movable between a retracted and an extended position. The boom extension sensor generates a first signal that corresponds to the distance which the boom is extended. The boom angle sensor generates a second signal that corresponds to the angle which the boom is pivoted. The control system receives the signals and displays a cursor located at a position that is based on the first signal and the second signal.

摘要： An industrial truck has load holding means (3) and a control device (6) to control a lifting movement of the load holding means (3). The control device (6) is connected with at least one operating element that can be actuated by an operator for the lifting movement. The control device (6) is connected with a load sensor (5) which generates a signal which is a function of the weight of a load on the load holding means (3). The control device (6) is realized so that an upward movement of the load holding means (3) is prevented if the weight of a load on the load holding means (3) exceeds a set weight limit.

摘要： A movement detection and warning system is provided and includes a transmitter means for transmitting a signal in association with an event or an object. The signal is adapted for triggering a detector means. The detector means is tuned to only detect the signal transmitted by the transmitter means when the detector is located within a predetermined distance from the transmitter means. The detector means activates an alarm means in response to being triggered by the transmitted signal thereby providing an early and distinct warning to people in the vicinity of the detector in order to eliminate or reduce the chances of the person sustaining injury. According to another aspect of the present invention there is provided a method of warning a person of the proximity of an object or event. According to the method, the object or event is associated with a transmitter means for transmitting a signal. The signal triggers a detector means and the detector is tuned to only detect the signal transmitted by the transmitter means. When the person and object or event are located within a predetermined distance from each other, the transmitter means transmits a signal to the detector means. In response, the detector means activates an alarm means in order to provide an early and distinct warning to the person in the vicinity of the object or event to alert the person to the presence of the object or event.

摘要： A pothole protection mechanism for a lift machine includes a frame that is securable to the lift machine, a pothole protection bar movably coupled with the frame via a support linkage, and an actuator coupled between the frame and the pothole protection bar. The actuator is sized for a force sufficient only to lift the pothole protection bar. The support linkage includes a coupling bar driven by the actuator that is connected between two pivot joints secured between the frame and the pothole protection bar. In the extended or deployed position, the pivot joints are pivoted to an over-center position and the coupling bar is abutted against a stop. As such, when a vehicle to which the pothole protection mechanism is attached falls into a pothole or off a curb or the like, the weight of the machine is supported by the pothole protection bar and support linkage and not by the actuator. In preferred forms, the pothole protection mechanism is without a mechanical linkage between platform lift and pothole protection mechanisms.
摘要翻译：一种用于升降机的坑洼保护机构包括可提升机器固定的框架，通过支撑联动装置与框架可移动地连接的pot坑保护杆，以及连接在框架和pot坑保护杆之间的致动器。致动器的尺寸适合于仅提升井底保护杆的力。支撑联动装置包括由致动器驱动的联接杆，该联接杆连接在固定在框架和井底保护杆之间的两个枢轴接头之间。在延伸或展开位置，枢轴接头枢转到超中心位置，并且联接杆抵靠止动件。因此，当安装有埋坑保护机构的车辆落入坑洞或路边等时，机器的重量由坑洞保护杆和支撑连杆而不是由致动器支撑。在优选的形式中，井底保护机构在平台升降机和井底保护机构之间没有机械连接。

摘要： A device for controlling tilt of a forklift mast. A fork for carrying an object is supported by the mast so that the fork is lifted or lowered. A tilt cylinder operates to tilt the mast hydraulically. A hydraulic valve supplies oil to the tilt cylinder in correspondence with the position of a tilt lever. The tilt cylinder tilts the mast at a speed corresponding to the flow rate of the oil supplied by the valve. A restricting valve is provided for restricting the maximum flow rate of the oil. When the fork is located below a predetermined reference position, the controller fully opens the restricting valve. However, when the fork is located at the reference position or higher, the controller restricts the opening of the restricting valve, thus restricting the maximum tilt speed of the mast. This stabilizes the forklift.
