Installation process of screw hoist

Installation process of screw hoist

1. When installing the screw hoist, the base layout plane must be 180º horizontal; the contact area between the base of the hoist and the base layout plane must reach more than 90%; the axis of the screw must be vertical to the horizontal plane measured on the gate; The plate lifting ear holes are vertical to prevent the screw from skewing, causing part of the force to damage the machine.

2. Place the manual screw hoist in 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 firm and safe. The concrete of the machine base and the foundation members shall be poured according to the rules of the drawings. When the concrete strength does not reach the planned strength, it is forbidden to remove and change the temporary support of the hoist, let alone trial adjustment and trial operation.

4. According to the lifting center line of the gate during installation, the center is aligned so that the vertical and horizontal center line error does not exceed plus or minus 3 mm, and the elevation error does not exceed plus or minus 5 mm. 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 comply with the rules of the drawings and instructions, and all electrical equipment are reliably grounded.

6. After the product installation is completed, the machine should be cleaned, repaired damaged maintenance paint, and filled with grease.
