摘要： A track vehicle includes a cab operable to support an operator. Left and right motors each rotate an output shaft at a first speed, and a speed reduction system is operably coupled to each output shaft. Left and right drive shafts are driven by the speed reduction system at a second speed that is slower than the first speed. Left and right drive sprockets are mounted for rotation with the respective first and second drive shafts. Left and right track carriages support the cab and left and right tracks are mounted for rotation about the track carriages in response to rotation of the respective left and right drive shafts, such that the left and right tracks are driven by the left and right drive sprockets to move the track vehicle along a ground surface.

摘要： A skid steer loader has an operator's cab mounted thereon pivoting about a horizontal pivot adjacent a forward edge of the frame of the loader and at the forward edge of the operator's cab. In a working position the cab overlies a portion of the frame that has operating components therein, and the cab can be pivoted to raise the rear of the cab to pivot it forwardly to an open position to permit access to components beneath the cab when its in its working position. The cab has positive latches for holding it in its working position, and an automatic stop to hold it in its open position. The latches are operated by levers on the back wall of the cab that are moved between a latched and unlatched position, and when they are in their unlatched position, a cover for the engine components cannot be closed.

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 loader boom assembly has articulated lift arms that have first and second lift arm sections pivotally mounted together. The rear lift arm section is pivotally mounted to rear portions of a prime mover frame. The main lift arm section is substantially longer than the first lift arm section and pivots on the outer end of the rear lift arm link. The lift arm sections are in a folded position when the lift arms are lowered, and a control link is provided to cause the lift arms to unfold as the lift arms are raised to keep the forward portion of the main lift arm section moving along a generally vertical path after a selected lift height to provide a better forward reach of the boom assembly at the higher range of lift. The proportional lengths of the lift arm sections and the control link and the placement of the pivot points and actuators on the main frame also provide structural integrity and efficient power utilization.

摘要： A work machine includes a frame supported for movement over the ground, a prime mover for driving movement of the frame, an operator compartment supported on the frame and a cradle coupling the operator compartment to the frame. The cradle is pivotable between an operating position and a service position and includes a biasing mechanism for biasing cradle toward the service position and an isolation mount coupling the operator compartment to the cradle. The isolation mount permits deflection of the operator compartment relative to the cradle along a selected axis. A latch mechanism releasably couples the cradle to the frame and a handle is provided for actuating the latch mechanism. The isolation mount includes a deformable member having a void defining the selected axis. The axis can be aligned with a force exerted on the cradle by the operator compartment to reduce stress on the biasing member.

摘要： A loader has an operator's station, comprising a cab with an operator's seat that is mounted on a pivot at the forward portions of the operator's station. An actuator is mounted between the operator's station and a loader frame to tilt the operator's station about the pivot a limited number of degrees when operating accessories mounted on a forward portion of the loader frame. The accessory is shown as a backhoe, and the forward tilting of the operator's station permits increased the downward field of view for an operator to observe the lower end of a digging arm of a backhoe at greater depths than with a fixed position operator's station.

摘要： A track driven machine has a pair of track frames on opposite sides thereof, and each of the track frames has a pair of laterally extending arms fixed thereto. The arms are joined to a machine frame only through vibration isolating elastomeric blocks that carry compression loads from the arms to the machine frame. The elastomeric blocks are held in place with bolts that pass through openings in the machine frame. There are second elastomeric blocks above each of the first blocks to support downward movement of the arms relative to the machine frame.

摘要： A lift arm assembly for a skid steer loader comprises a pair of lift arm links that are pivotally mounted together at first ends of the links. A first lift arm link is of substantial length and is pivotally mounted to the frame of the skid steer loader adjacent the rear lower portion of the frame and extends upwardly. A second lift arm link extends forwardly from the first lift arm link pivot to a position ahead of the skid steer loader frame. A control link is provided that has one end pivotally mounted to the loader frame adjacent a forward end of the loader frame, and a second end pivotally mounted to the second lift arm link to guide the second lift arm link as it is raised. An extendable and retractable actuator is pivotally mounted at a first end to the first lift arm link adjacent to the pivot of the first lift arm link to the frame. A second end of the actuator is pivotally mounted to the second lift arm link forwardly of the first lift arm length link. The control link is of length, and its pivots are located such that the outer end of the first lift arm link moves in a substantially vertical path as the actuator is extended and retracted.
