Installation steps of screw hoist

Installation steps of screw hoist

1. When installing the screw hoist, be sure to keep the base layout plane 180º horizontal; the contact area between the base of the hoist and the foundation layout plane must reach more than 90%; the screw axis must be vertical to the horizontal plane measured on the gate; The plate lifting ear holes are vertical to prevent the screw from tilting, causing local stress and damaging the parts.

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

3. The foundation for installing hoist must be stable and safe. The concrete of the machine base and basic components shall be poured according to the drawings. When the concrete strength does not reach the design strength, the temporary support of the hoist is not allowed to be removed and changed, and no trial adjustment and trial operation are allowed.

4. According to the lifting center line of the gate during installation, the center should be aligned so that the vertical and horizontal centerline 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. For the installation of the electrical equipment of the product, it must comply with the requirements of the drawings and instructions, and all electrical equipment must be reliably grounded.

6. After the product is installed, clean the machine, repair the damaged protective paint, and fill with grease.
