We must be serious and responsible in our work, especially in our daily work. If we want to use it handily in our daily work, we must ensure that the product is on standby at all times and that there is no problem with the maintenance of the product. It is strictly forbidden to cause the product to become ill. Responsible, let me explain how to standardize the use of group hoist. (1) When the group hoist is not working, do not hang the product in the air to prevent deformation of the parts. (2) It is forbidden to use it in an environment that is not allowed during use, and it is strictly prohibited to overload it. (3) In many cases, the group hoist is used by multiple units, so it is strictly forbidden to press the upper and lower buttons at the same time during use. (4) Cut off the power supply immediately after using the product to avoid danger. (5) During the process, the product must be inspected by professional personnel on a regular basis, and measures must be taken in time when a failure occurs, and records must be made. (6) Enough lubrication must be maintained during use, and it must be clean and free of any debris.
