Although the figure shows that the fork and the fixing bracket 110 are coupled by the bolt 112, the present invention is not limited thereto and the fixing bracket 110 can be coupled in any way as long as the fixing bracket 110 is not detached from the fork.

The roll fixing portion 120 is formed to have a predetermined length and is inserted into the pipe 2 at the center of the roll 1 to grip the roll 1. [

In this embodiment, the roll fixing portion 120 is fixed to a rotation bracket 130, which will be described later, and can be configured to expand or contract in the radial direction by hydraulic pressure. Therefore, when the roll fixing portion 120 is inserted into the pipe 2 at the center of the roll 1, the roll fixing portion 120 is extended so as to contact the inner circumferential surface of the pipe 2, can do. At this time, the roll fixing portion 120 can be expanded to a state where its diameter is slightly larger than the inner diameter of the pipe 2. [

The roll fixing part 120 may be provided with a fluid inlet 122 for injecting a fluid for expanding the roll fixing part 120. [ Here, the fluid may be a liquid or a gas. An air compressor is connected to the fluid inlet 122 to expand the roll fixing portion 120 by injecting gas so that the roll fixing portion 120 can be firmly fixed to the roll fixing portion 120. [

Generally, the lifting device such as the forklift 10 or the crane 30 is provided with a hydraulic system for lifting the cargo. In this embodiment, the roll fixing part 120 is fixed by the hydraulic system provided in the lifting device Expanded or contracted.

In particular, if the hydraulic system provided in the lifting device is operated by pneumatic pressure, the roll fixing part 120 can be expanded or contracted by using the hydraulic system of the lifting device without having to provide a separate air compressor. Thereby, the volume and weight of the apparatus can be minimized, and the cost can be saved.

In addition, the outer circumferential surface of the roll fixing part 120 may be coated with a material having elasticity such as rubber, synthetic resin, or the like. Thus, when the outer circumferential surface of the roll fixing portion 120 comes into contact with the inner circumferential surface of the pipe 2, it is possible to improve the frictional force and prevent the roll 1 from coming off.
