摘要： A control apparatus controls movement of a lift arm (18) and tool (28) on a skid steer loader. Power actuators (22, 32) are coupled to a lift arm circuit (42) and a tool circuit (42) for moving the lift arm (18) and tool (28) along a path. A sensor (44) is coupled to the skid steer loader for sensing a desired parameter and providing a signal indicative of the desired parameter. A power interrupter (52, 54, 56) is coupled between the power actuators (22, 32) for the lift arm and tool and the sensor and interrupts power to the actuators (22, 32) based on the signal. A manually operable bypass mechanism (58) is coupled to the power interrupter and the power actuators (22, 32) and is used to bypass the power interrupter (52) to allow movement of the lift arm (18).

摘要： A power machine (10) has a base (12), an operator support portion (14), and a hydraulic slew motor coupled to move the operator support portion (14) relative to the base (12). A boom (52), an arm (64), and a tool (76) are all coupled to one another and to the operator support portion (14) and are powered by hydraulic actuators. A slew valve is coupled to receive hydraulic fluid under pressure from a hydraulic power circuit and is also coupled to the slew motor to provide hydraulic fluid to the slew motor and receive hydraulic fluid from the slew motor. A first power actuator valve is coupled to receive hydraulic fluid from the slew valve and is coupled to provide hydraulic fluid to one of the hydraulic boom actuator, the hydraulic arm actuator and the tool actuator. The slew valve is coupled in series with the power actuator valve.

摘要： A bracket (24) holds a detachable frame (48) attached to a bucket (20) or other tool. The bracket (24) mounts onto the arm (16) of the implement. The bracket (24) carries a latch member (41). The bracket (24) can be moved onto a frame (48) on a bucket (20) or other tool, and is latched in place without dismounting from the backhoe or excavator (10). The latch member (41) can be released, either manually or under power, and then by manipulating the arm (16), the tool (20) and frame (48) can be removed from the bracket (24) and a new tool mounted. The engaging portions of the frame (48) and bracket (24) are such that as wear occurs, the parts will compensate and remain secured without play or slop.

A position sensor (46) is coupled to the movable element and provides a position signal indicative of a position of the movable element. A controller (48) is coupled to the position sensor to receive the position signal and provide a control signal based on the position signal. A valve spool (52) controls flow of hydraulic fluid to the hydraulic cylinder. An actuator (50) is coupled to the controller and the valve spool and moves the valve spool in response to the control signal from the controller.
