Claims

[Scope of utility model registration request]

A first differential gear device is connected to the opening/closing drum of the unloader via a reducer, a second differential gear device is connected to the support drum via a reducer, and the first and second differential gears are connected to the opening/closing drum of the unloader. The dynamic gear device includes a first rotating body made of a spur gear or a sprocket, input side and output side bevel gears arranged coaxially with the rotating body and facing each other so as to be rotatable independently of each other, and the first rotating body. a transmission gear that is rotatably held by a rotating body and meshes with the input and output side bevel gears, and a second transmission gear that is rotatably held by a rotating body of the first differential gear device. A rotating body and an actuating member are attached to the first differential gear of the second differential gear.
The rotating body is connected to the second rotating body, and a limit switch is disposed on the rotational movement locus of the operating member to detect the upper limit of hoisting and the lower limit of hoisting by the support drum, and the second differential gear An emergency limit switch adjustment device for an unloader, characterized in that the output side bevel gear of the device is coupled with adjustment means for stopping the rotation of the bevel gear and rotating it by a desired amount.
