How to install and adjust screw hoist

Before installation, it is necessary to check whether the various parts are good, whether the grease is on the foot, whether the anchor bolts are loose, and whether the relevant technical statistics between the two are consistent.

1. Before installation, it is necessary to check whether the parts are good, whether the grease is on the foot, whether the anchor bolts are loose, and whether the relevant technical statistics between the two are consistent.

2. During installation, the level of the basic layout plan must be maintained at 180°; the total contact area between the gate hoist base and the basic layout plan must exceed about 90%; the centerline of the screw rod must vertically bisect the sea of ​​the load-bearing beam on the gate platform. Plane: It must be vertical to the lug hole of the gate to prevent the screw rod from skewing, causing partial support and destroying the parts.

3. After installation, a trial run must be performed. Once a no-load test is performed, the screw rod is arranged for 2 strokes, and whether there is any abnormal noise, check whether the installation meets the technical standards. Second, make a load test. Under the rated load, make two stroke arrangements to observe the operating conditions of the screw rod and the sluice to see if there are any abnormalities. Once the accuracy is confirmed, the operation can be declared. After the load has been in operation for a period of time, the initial maintenance should be carried out. The metal material foam caused by the friction of the new parts of the fuselage is very screw, nut, pressurized, and worm. It should be cleaned and cleaned with lubricating grease and sealed. Sexually strict, apply again.
