1. Marking: Reflective film marks indicating the height scale must be affixed to the two pillars of the flexible lifting gate to ensure correct visual inspection of the lifting height of the gate. At the same time, it also plays the role of visible marking of the column when transporting the segment at night; the two sides of the column must also be affixed with a prohibition mark that does not allow people to stand under the gate when it is lifting.

2. Sensing, detection and audible and visual alarm system: Flexible lifting gates must be equipped with audible and visual alarms, which emit audible and optical signals during lifting and lowering. It is forbidden for the operator to walk below while the doors are lifting. The side of the pulley set is equipped with a sensing limiter, so that when the gate is completely closed or fully opened, the lifting mechanism immediately stops running.

3. Technical guarantee: The design basis of the flexible lifting gate must refer to the relevant national standards for lifting machinery, steel structures, and electrical appliances; the strength, deflection, internal force, and stability of the steel structure are calculated and checked to ensure the design reliability of the product; The selected raw materials, purchased parts, matching parts, mechanical parts and well-known domestic manufacturers and brand-name products are selected. The components of the control device must be imported products. If the lifting mechanism part fails or is damaged, the main body of the gate is required to stop descending immediately, and an emergency automatic clamping device is required, and the main body of the gate is not allowed to fall out of control under any circumstances.

4. The flexible door (6 sets) of the painting booth of the painting workshop to which it belongs must adopt explosion-proof components. The motor may not use explosion-proof motors, but it must ensure that its working area is isolated from the painting working area. do.
