Tie-In Point Standards for Elevators

Tie-In Point Standards for Elevators

I. Installation Location of Tie-In Points

  1. Tie-in points should be installed on the elevator tower, top floor, and bottom floor frames. They should be located within the working range of construction personnel and not extend beyond the main body of the elevator.
  2. The maximum distance between the tie-in point and the safety net or guardrail should not exceed 1.5 meters; the distance between tie-in points should not be too large, generally controlled within 2.5 meters.
  3. Tie-in points should be set on structures with reasonable bearing capacity, and the quality and reliability of the components should be checked.

II. Quantity of Tie-In Points

  1. The number of tie-in points should be determined according to the model of the elevator and the working environment, and should meet the safety needs of construction personnel.
  2. The setting of tie-in points should comply with the safety factor specified in the current "Code for Construction Safety in Buildings" (GB/T 50346-2010).

III. Strength of Tie-In Points

  1. Tie-in points must meet the strength and seismic requirements and should reach a safety factor of 1.5 times the load.
  2. The installation of tie-in points should be carried out according to the standards provided by the elevator manufacturer.

IV. Other Precautions

  1. During the use of the elevator, the use condition and strength of the tie-in points should be checked regularly. If there are loose, deformed, or cracked conditions, they should be replaced or repaired in time.
  2. Before using the elevator, the tie-in points should be subjected to load tests and maintenance to ensure their normal use.
  3. When using the elevator, construction personnel should wear safety belts correctly and fasten them to the tie-in points to ensure safety.

This article introduces the installation location, quantity, and strength standards of elevator tie-in points. The formulation of these standards aims to ensure the safety of elevators during construction and is intended to help construction personnel use tie-in points correctly and ensure construction safety.
