How to Properly Manage the Installation of Construction Elevators

A construction hoist is a vertical lifting machine installed on the exterior of a building for transporting construction personnel and building materials. Construction practice has proven that using construction hoists for the vertical transportation of personnel and materials in high-rise construction can significantly save labor hours and improve labor productivity.

The construction elevator is an external elevator and is large equipment at a construction site, so it involves a certain degree of danger. Compared with gantry-frame and derrick-frame material hoists, the construction elevator has concentrated personnel in the cage; once an accident occurs, the degree of casualty and injury is greater.

1. The installation site and surrounding environment shall be cleaned up, and warning rods, etc., shall be used to enclose the area to prohibit unauthorized personnel from entering.

2. Simultaneous overhead and underfoot cross-operation is prohibited. To prevent objects from falling above the installation location below the scaffold, safety nets shall be added when necessary.

3. During installation, a dedicated person shall be responsible and unified command shall be exercised.

4. When the hoist is running, the operator’s head and hands must never extend beyond the safety railing.

5. When using the suspension rod for installation, overloading is not allowed. The suspension rod may only be used to install and dismantle hoist parts and shall not be used for other lifting purposes.

6. If anyone is working on the guide rail frame or wall-attached frame, the hoist must not be started. When the cage is raised, entering the outer cage is prohibited.

7. All parts and components on the cage must be placed stably and must not extend beyond the safety railing.

8. When there are suspended objects on the suspension rod, the cage must not be started.

9. Installation workers shall comply with the safety requirements for work at heights, including wearing safety helmets, safety belts, anti-slip shoes, etc. Do not wear excessively loose clothing; wear company uniforms to avoid being caught in moving parts and causing safety accidents.

10. To operate the hoist, the control box must be brought to the top of the cage; operation inside the cage is not allowed.

11. Before starting the cage, a complete inspection shall be carried out first, and all hidden safety hazards shall be eliminated.

12. During installation and operation, loading shall be carried out according to the rated load of the hoist; overload operation is not allowed.

13. Installation work shall not be carried out in thunderstorms or severe weather with a wind speed exceeding 13 m/s.

14. Before the hoist is operated, the protective grounding device shall first be connected to the metal structure of the hoist; the grounding resistance shall be ≤4Ω.

15. The maximum operating height shall not exceed 200 m.

16. Workers must follow commands. Good methods and suggestions must be discussed in advance and may be implemented only after approval by the on-site construction and technical person in charge; otherwise, the work plan must not be changed without authorization.

17. During installation of the construction elevator, ensure there are no obstacles near the entire travel path that could impede safe operation, and necessary protective barriers shall be erected.

18. When work is carried out with the cooperation of a tower crane, the commander must work close to the elevator, and during lifting and positioning, the load must be lifted gently and lowered slowly.
