摘要： In vehicles for material handling commonly known as lift trucks, it is known to have forks for lifting and supporting the material being handled. In this invention, the curved portion of the fork, known as the "heel" is modified to reduce the stresses which arise in this area when the fork is loaded. The modifications include thickening of the heel during forming by approximately 5% toward the blade and approximately 2.5% toward the shank, enlarging the inside radius of the heel by machining and providing a clearance cavity in the top surface of the region where the blade meets the heel. Also disclosed is a process for manufacturing lift truck forks comprising bending, then upset using a backing die of proper configuration to form a thickened portion of the heel which tapers into the lower portion of the blade, followed by restriking with a die suitably shaped to form an appropriate inside radius and clearance cavity in the heel, heat treatment and final machining to remove surface anomalies and give the desired configuration to the inside radius.

摘要： A signalling system includes first and second signalling devices. The first signalling device including a retro-reflector modulator, having a lens, a modulator and a reflector, and being operable to receive, modulate and reflect the modulated signal back to the second signalling device. The second signalling device including a signal generator, a receiver for receiving the modulated signal from the first signalling device and a processor for retrieving modulation data from the received modulated signal. The lens of the first signalling device includes a telecentric lens.

摘要： A fork for a fork lift truck is attached to the typical mast mounted carriage by means of upper and lower hangers. Lateral adjustment of the position of the fork relative to the carriage involves engagement and release of a pin structure carried by the upper hanger. The upper hanger incorporates a pin which is vertically movable between a first position in which the pin engages slots in the upper mounting bar of the carriage and a second position in which the pin is recessed permitting lateral, relative movement between the fork and the carriage. A spring urges the pin to the first position where the pin engages slots in then carriage mounting bar. By lifting and turning the pin can be held in a second position so that the fork is slidable laterally along the carriage mounting bar.
