River special screw hoist steel gate

.When installing the screw hoist, the base layout plane must be kept horizontal
The contact area between the hoist base and the foundation layout plane must be at least %
The screw axis must be vertical to the gate platform The horizontal plane to be measured should be vertical to the gate lifting lug holes to prevent the screw from tilting, causing local stress and damaging the machine parts. <
. Place the manual screw hoist in the installation position. Put a limit plate on the screw, screw the screw into the machine from the bottom of the beam, and then put the limit plate on the screw when it is exposed from the top of the machine. The bottom of the screw rod is connected with the gate.
<
The foundation for installing the hoist must be solid and safe. The concrete for the machine base and basic components must be poured according to the provisions of the drawings. When the strength of the concrete does not reach the design strength, the temporary support of the hoist is not allowed to be removed or changed, let alone trial adjustment and trial operation.
<
When installing, according to the lifting centerline of the gate, find the center so that the vertical and horizontal centerline deviation does not exceed plus or minus,
the elevation deviation does not exceed plus or minus
. Then the second stage concrete is poured or connected with the embedded steel plate.
<
. The installation of the electrical equipment of the product must comply with the requirements of the drawings and instructions, and all electrical equipment must be reliably grounded.
