ABSTRACT:
A lift truck includes a guide member secured to a mast of the lift truck and a guided member secured to a carriage vertically movable along the mast. The guided member engages with the guide member to resist twisting moments acting on the carriage and enable the carriage to move smoothly along the mast. A lift truck attachment for mounting on a lift truck includes a latching member which can restrict movement of the attachment with respect to the lift truck in a fore-and-aft direction of the lift truck.
