Installation steps of screw hoist

Installation steps of screw hoist:

1. When installing the screw hoist, it is necessary to adhere to the base layout level of 180º; the contact area between the base of the gate hoist and the base layout plane must reach more than 90%; the screw axis must be perpendicular to the level of the gate; The lifting ear holes of the ram are vertical to prevent the screw from tilting, forming part of the force and damaging the parts.

2. Place the manual screw hoist at the device position. Put a limit disc on the screw, screw the screw into the machine from the lower part of the beam, when the screw is exposed from the top of the machine, put the limit disc. The bottom of the screw is connected with the gate.

3. The foundation of the device hoist must be stable and safe. The concrete of the machine base and foundation members shall be poured according to the rules of the drawings. When the concrete strength has not reached the design strength, the temporary support of the hoist is not allowed to be removed and modified, and the trial adjustment and trial operation are not allowed to be stopped.

4. According to the lifting center line of the gate during installation, the center is aligned so that the vertical and horizontal center line deviation does not exceed plus or minus 3mm, and the elevation deviation does not exceed plus or minus 5mm. Then the second-stage concrete is poured or connected with the embedded steel plate.

5. Regarding the installation of the electrical equipment of the product, it must conform to the rules of the drawing and the clarification book, and all electrical equipment are firmly grounded.

6. At the end of the product installation, it is necessary to stop the liquidation of the machine, repair the damaged maintenance paint, and fill with lubricating grease.
