First of all, the installation point of the lifting racks is four top seat pulleys, a corner rotator, and a hand crank, which are required to be firmly fixed on the ceiling and the wall. The principle of installation of the four top seat pulleys is on a plane with no obstacles in the middle so as not to affect the sliding of the wire ropes. The plane of the ceiling must be at right angles to the wall of the hand crank, so as to ensure that the wire rope is always in the sliding process. The center position of the pulley makes the pulley evenly stressed and turns normally.
Secondly, when hanging a gypsum roof, the shape should not be too much, and it must be recessed upwards, and do not protrude downward so as not to affect the sliding of the wire rope. When modeling, consider installing the position of the top rack of the lifting rack. Two reinforcement timbers must be reserved. The timber must be connected with the cement roof above to reinforce the tensile force.
Thirdly, consider the position of the automatic rack hanger in the decoration design, and pay attention to the installation facilities of the hand crank, such as whether the water circuit, the circuit, the position of the switch socket, the position of the faucet, whether it affects the position of the furniture, Affect the use of curtains, etc.
