摘要： PURPOSE:To make steering operation smooth and downsize the construction. CONSTITUTION:In a carriage in which a caster 26 is provided under a frame 20 and a handle 6 is provided rotatably at the end of the frame through a bracket 31, a motor 35 for driving the caster is provided on the bracket. Then two limit switches 41a and 41b and two centering springs 42a and 42b are provided in parallel with each other, respectively, between the supporting member on the bracket side and the handle at any interval. Thus, when the handle is rotated, either one of the limit switches is turned on to drive the motor in the same direction as the handle.

摘要： PURPOSE:To make it usable for multipurposes in addition to safety and high reliability by forming a locking mechanism in space between a lock nut and a cylinder, while setting up a driving cylinder for releasing this locking mechanism as rotating these elements relatively, and adding a drive motor to control their relative rotation. CONSTITUTION:Hydraulic pressure is fed to a pressure chamber 47 of a driving cylinder B, and an oil motor 53 of a drive motor C is operated, rotating a lock nut 32 clockwise, and this lock nut 32 is moved up as extending a piston rod 42, then a locking mechanism consisting of those of knurling, projection and hole or the like at its end face is released. Simultaneously hydraulic pressure is led into the cylinder, thereby extending a ram. When the ram is extended up to a specified position and intended to be locked, hydraulic pressure in the driving cylinder B is put back to a tank, and the piston rod 42 is compressed, rotating the oil motor 53 of the drive motor C counterclockwise, and the lock nut 32 is rotated and lowered in cooperation with pressing action by its own load, and when the lock nut 32 has hit on a cylinder head, rotation is prevented by the locking mechanism and the ram is locked.
