Attention to the installation of screw hydraulic hoist

1. Be sure to adhere to the level of the foundation placement plane at 180o; the touch area of ​​the hoist base and the foundation placement plane must reach more than 90%; the screw axis must be straight to the horizontal plane measured on the gate; it must be straight with the gate ear hole to prevent The screw is inclined to cause local stress and damage the machine parts.

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

3. The foundation structure of the hoist must be stable 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 harmony and trial operation.

4. According to the hoisting center line of the gate, the device hoist is centered so that the vertical and horizontal center line error does not exceed plus or minus 3mm, and the elevation error does not exceed plus or minus 5mm. Then the second-stage concrete is poured or connected with the embedded steel plate.

5. The device of the electrical equipment of the hoisting machine conforms to the rules of the drawings and instructions, and all electrical equipment are reliably grounded.
