Overview

Precautions for installation by high lift winch hoist manufacturers; $r$n$r$n1、 During installation, the foundation of the base should be firm and flat, leaving a position for the foot screws. After the opening and closing machine is in place, it should be leveled and poured into shape. $r$n2、 First, wrap the steel wire rope around the balance wheel, with the rope length evenly distributed on both sides. Then, wrap the steel wire rope around the pulley assembly and fix both ends at the end of the drum.

Product Details

High lift hoist manufacturerInstallation method: First, place the screw from the reserved hole of the hoist to the lifting ear position of the gate. Connect the lower end of the screw to the lifting ear of the gate door panel (pin connection). Then separate the hoist base from the electric device (loosen the connecting bolt) and remove the nut sleeve of the hoist base. Next, insert the hoist base from the upper end of the screw and fit the nut into the hoist base. Adjust the vertical position of the machine base and screw with the gate (must be adjusted to the same line as the axis of the gate). Next, install the electric device (tighten the connecting bolt), and weld the connecting steel plate on the hoist base to the embedded plate, completing the installation of the gate, hoist, and screw.

debugging method

（1） Firstly, provide a three-phase four wire power supply connected to the electrical control box L1, L2, L3, N three-phase 380V AC ± 10%, 50HZ

（2） The wiring process of connecting the electrical control box to the hoist:

(1) The power line (motor) is three-phase 380V, with an additional grounding wire.

(2) Control line, connect to the hoist according to the wiring diagram of the control box.

High lift hoist manufacturerDebugging of the opening and closing machine
1. Under no-load conditions, ensure that the three-phase current imbalance does not exceed plus or minus 10%, and measure the current value. 2. Adjustment of upper and lower limits: When the gate is fully closed, press the upper limit switch tightly and fix it on the screw. When the gate is fully open, press the lower limit plate down on the travel switch and fix it on the screw. 3. The adjustment of the main controller of the hoist must ensure that the error when the gate is raised and lowered to the upper and lower limits does not exceed 1cm. 4. After installation, a trial run must be carried out, and a no-load test must be conducted, which involves allowing the screw to travel in two strokes, listening for any abnormal sounds, and checking whether the installation meets technical requirements. Conduct a load test, perform two strokes under rated load, observe the operation of the screw and gate, and check for any abnormal phenomena. Only after confirming that there are no errors can it be officially put into operation.
