Installation, use and maintenance of flashlight screw hoist:
Screw hoist:
Be sure to keep the foundation layout plane level
The contact area between the hoist base and the foundation layout plane must reach
%
The above screw axis should be perpendicular to the horizontal plane measured on the gate platform, and the horizontal plane measured on the gate platform should be perpendicular to the gate lifting eye hole to prevent the tilt of the screw from causing local stress and damage to the machine parts.
, Place the hoist in the installation position. Put a limit plate on the screw, screw the screw into the hoist from the lower part of the beam, and then put the limit plate on the screw after it emerges from the top of the hoist. The bottom of the screw rod is connected with the gate.
The basic building installation of the hoist must be stable and safe. The concrete for the machine base and basic components shall be poured according to the provisions of the drawings. When the strength of the concrete does not reach the design strength, it is not allowed to dismantle or change the temporary support of the hoist, and it is not allowed to conduct trial adjustment and trial operation.
. Install the hoist and find the center according to the gate lifting centerline so that the 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.
