How to Carry Out Protection Work for a Construction Hoist

First, we must maintain the cage door and landing door of the construction hoist, because many faults occur on these doors. We should apply oil to the door sill frame to lubricate it well, so that the hoist will not make strange noises during use. We should also check the switch of the safety touch panel, because the doors open and close frequently, and the switch wires are easily damaged.

Of course, we must not forget to lubricate the traction machine of the hoist. We should open the oil nipple and check the oil level. If the oil level is too low, we must add oil to the traction machine. If we do not add oil, the traction machine and motor may burn out during operation.

For a construction hoist, its technical level is reflected not only in research and development, design, and production, but also in the installation and operation performed by workers.

Do not underestimate these operators. Directing and controlling a hoist is not a job that just anyone can do; it must be done by personnel who have received professional training and obtained the relevant operation certificate. Generally, it is carried out by a professional team. Before a hoist can be used, it must first be installed, and the installation work must be handed over to these professionals.

During installation, there are many aspects that need attention. Here are a few examples.

First, the foundation of the construction hoist should be poured with concrete so that its bearing capacity is greater than 150 kPa. Second, attention should be paid to controlling the stability of the hoist; the installation dimension between the longitudinal center of gravity of the guide rail and the outer wall should preferably be as small as possible. In addition, during installation, a theodolite should be used to calibrate the direction of the hoist, and the deviation should be controlled within 5/10,000, or 0.05%.

Of course, in addition to these aspects, the design of the guide rail frame, switch box, cage, and other parts also demonstrates the technical capabilities of construction workers in the new era.
