Abstract: A battery and battery lifting system for a mining or construction vehicle, the vehicle having a frame, the system having a battery, the battery having at least one slot, the at least one slot having vertical sidewalls which extend toward convergence, and at least one wedge-shaped arm for lifting the battery, the at least one wedge-shaped lifting arm having a bellcrank and a leveling arm for pivotally coupling to the frame, whereby the at least one wedge-shaped lifting arm is guided and aligned with the battery as the at least one wedge-shaped lifting arm moves inwardly in the direction of convergence along the vertical sidewalls. The at least one wedge-shaped lifting arm having a hydraulic cylinder. The hydraulic cylinder having a shaft with a locking plate located at the end of the shaft. The locking plate is used to lock the battery to the at least one wedge-shaped lifting arm.

Abstract: A lift vehicle for moving mine roof supports has a main drive section with a forward lift platform and a rearward articulated battery section. The articulating connection between the main section and the battery section has a clevis and pin assembly and a rotatable sleeve bearing connection. The sleeve bearing is rigidly connected to the clevis and pin assembly and rotatably connected to the battery section. The lift platform is rotatable about a horizontal axis to give it a tilting capability and is rotatable about a vertical axis to assume angled positions to either side of the vehicle.
