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.

Abstract: A wheel puller for use on large wheel and tire assemblies has a plate adapted for attachment to a tire rim. A back plate is spaced apart from this plate and extends across the axis of the wheel hub. Two wedge blocks are placed between the back plate and the wheel hub on either side of the center line of the wheel hub. A driving wedge is inserted between each wedge block and the back plate.In the process of using the wheel puller, the driving wedges are alternately tapped with a light hammer to pull the rim away from the hub. If necessary wedging spacers may be inserted between the driving wedges and the backplate to increase the distance that the wheel rim may be driven off the hub.
