摘要： A control apparatus controls movement of a lift arm and tool on a skid steer loader. Power actuators are coupled to the lift arm circuit and the tool circuit for moving the lift arm and tool along a path. A sensor is coupled to the skid steer loader for sensing a desired parameter and providing a signal indicative of the desired parameter. A power interrupter is coupled between the power actuators for the lift arm and tool and the sensor and interrupts power to the actuators based on the signal. A manually operable bypass mechanism is coupled to the power interrupter and the power actuators and is used to bypass the power interrupter to allow movement of the lift arm.

摘要： A power machine has a base, an operator support portion, and a hydraulic slew motor coupled to move the operator support portion relative to the base. A boom, an arm, and a tool are all coupled to one another and to the operator support portion 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 pair of pivoting parts are held together with a pin, with a first part, such as a rod end of a hydraulic actuator, positioned between two flanges of a bracket, with the flanges having surfaces mating with sides surfaces of the rod end. A seal is placed in each of a pair of recesses on the opposite side surfaces of the rod end to provide an annular seal around the surface of the pin as the parts pivot, and also having a flange forming a side seal that seats on one of the mating surfaces of the bracket at a location spaced outwardly from the pin and extending annularly around the pin. The seal portion engaging the pin is spaced inwardly from the respective side surface of the bracket, and the outer annular lip seals a space surrounding the pin to form a pocket to receive grease that is used to lubricate the pin relative to the rod end.
