An improved torque sensor for detecting the direction and the magnitude of a torque applied to a shaft. The sensor includes a magnetostrictive layer, a pair of bearings, a stator and two nuts. The sleeve is fixed the circumference of the shaft. The layer has a magnetostriction effect in accordance with torque applied to the shaft. A pair of collars are fixed to the shaft at opposite ends of the layer. The bearings are connected to the shaft. Each bearing contacts one of the collars. The stator accommodates two pairs of coils. Each coil pair includes an exciting coil and a detecting coil. The coils surround and face the magnetostrictive layer. The axial position of the stator is determined by the bearings. Each nut is threaded to a threaded portion fixed to the shaft and presses one of the bearings against the corresponding collar. Accordingly, the axial position of the stator is determined.

Magnetostrictive torque sensor

The present invention discloses a load lifting unit for a lift truck, and more particularly, an improved structure of a load lifting unit for a counterbalance type lift truck. In the invention, to increase the loading capacity and longitudinal stability of the lift truck as well as to improve the forward view from the lift truck, two lift cylinders (7) are separately disposed on the sides of a pair of upright assemblies (1) of the load lifting unit, respectively, to provide a space (17) between the upright assemblies for allowing a lift member (4) to be lifted and lowered within the space and for allowing actuating means of various operations attachments engaged with the lift member to be accommodatedly arranged within the space.
