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.
