Abstract: A skyline logging carriage wherein the winch drum around which the load line is wound is powered by a fluid motor through a worm gear arrangement which eliminates the need for a separate braking system. The fluid motor is driven by a fluid pump powered by a diesel engine mounted on the carriage frame. The hydraulic transmission of power to the winch drum eliminates the need for clutches or direct mechanical connection and braking systems generally required. Greater freedom in placement of the winch drum in relation to the fairlead to obtain an optimum fleet angle and distance between the winch drum and fairlead for proper level winding of the load line about the winch drum is made possible by hydraulic transmission of power to the winch drum. Operation of the winch line is radio controlled by an operator at a yarder or other location. The carriage is moved along the skyline by a main line or main line and haulback lines.
Abstract: A winged friction shoe is provided to frictionally engage both the side frame column and bolster in order to control the oscillating movement of the latter. The wings of the friction shoe are formed with a surface which is inclined with respect to the surface which they engage to provide a couple force which urges the shoe into lateral alignment with a friction surface when the friction surface and shoe are initially in a laterally non-parallel relationship.
Abstract: A releasable stop for releasably stopping a vehicle moving through a conduit. A stop gate is supported for pivotal movement into and out of the path of movement of the vehicle. First and second arms are pivotally connected together between the gate and a support and a pneumatic piston and cylinder assembly actuates one arm for moving the gate between a closed and opened position. The pivoting arms are moved into or slightly past a dead center position when the gate is in the closed position whereby the impact of a vehicle engaging the gate will be transmitted to the support instead of to the piston and cylinder assembly. When the gate is closed, the dead center position of the arm maintains the stop gate in a locked position. The stop gate may be sized and shaped to entirely block the conduit to provide a dead end air cushion stop assist.
