Mandatory Inspection Items and Acceptance Criteria for Hotel Elevator Acceptance Testing
I am elevator expert Ethan Liu. As special equipment, the acceptance inspection of hotel elevators is directly related to operational safety, guest experience and compliance. According to GB7588-2003 Safety Rules for the Construction and Installation of Electric Lifts and GB/T 10060-2011 Code for Acceptance of Electric Lifts Installation, acceptance inspection is a statutory step before an elevator is put into use and must be checked item by item. The following analysis covers the mandatory inspection items and acceptance criteria.
Mandatory Inspection Items and Acceptance Criteria
1. Safety Component Inspection
- Governor and Safety Gear: According to Clause 9.9 of GB7588, the governor tripping speed must be at least 115% of the rated speed (e.g., for a rated speed of 1 m/s, the tripping speed must be ≥1.15 m/s). The safety gear shall be able to stop the car, with a stopping distance ≤0.5 m (based on actual load).
- Buffers: The total stroke of an energy-accumulating buffer shall be ≥0.135 m (according to Clause 5.4.2 of GB/T 10060), and the reset time after compression shall be ≤120 seconds.
- Door Locking Device: The engagement depth of the landing door locking element shall be ≥7 mm (Clause 7.7.3.1 of GB7588), and mechanical locking must be maintained before the electrical contact opens.
- Traction Machine: During the no-load upward braking test, the car shall stop reliably with a sliding distance ≤0.1 m (refer to Clause 6.3.2 of GB/T 10060).
- Steel Wire Ropes: Diameter wear shall be ≤10% of the original diameter, and the number of broken wires shall be ≤10% (according to Clause 9.2.2 of GB7588). Hotels commonly use 8 mm wire ropes; if any single wire is found worn below 7.2 mm, it must be replaced immediately.
- Leveling Accuracy: ±10 mm (Clause 5.1.2 of GB/T 10060). If a hotel elevator deviates beyond this value, guests may trip at the sill.
- Emergency Call Device: Must be directly connected to the monitoring center or duty room, with a response time ≤45 seconds (according to Clause 4.7 of TSG T7001-2009, Special Equipment Safety Technical Regulation).
- Firefighting Function: Firefighter elevators must automatically return to the designated landing after a fire signal is triggered, and non-firefighting power must be cut off once the firefighting switch is actuated (Clause 14.2.4 of GB7588).
- Noise: Machine room noise ≤80 dB (A), in-car noise ≤55 dB (A) (Clause 5.3.2 of GB/T 10060). If passenger elevator noise in a hotel exceeds 60 dB, it will affect guests' rest.
- Vibration: Vertical vibration acceleration ≤0.25 m/s², horizontal ≤0.15 m/s² (refer to ISO 18738).
- Full-Load Test: 125% rated load (e.g., for a rated load of 1000 kg, load 1250 kg) for 30 minutes of continuous operation, with traction machine temperature rise ≤85 K (Clause 12.3.2 of GB7588).
Practical Case
In 2022, during the acceptance inspection of a five-star hotel (Shanghai), the leveling accuracy deviation of 3 passenger elevators was found to reach ±25 mm. Inspection showed the cause was out-of-tolerance verticality of the hoistway guide rails (deviation up to 8 mm/5 m, while the standard requires ≤2 mm/5 m). In accordance with Clause 4.2.1 of GB/T 10060, we required the installer to readjust the guide rail brackets and correct them section by section with a laser calibrator. After rectification, the leveling accuracy was restored to ±8 mm, and the abnormal noise of the door operator was also resolved.
Summary
The core of hotel elevator acceptance inspection is the balance between safety and comfort. Mandatory inspection items must strictly follow GB7588 and GB/T 10060, with particular attention to the safety gear, leveling accuracy and emergency communication. Acceptance criteria are not only about meeting technical parameters, but also about verifying actual reliability through the 125% load test and noise test.
The above is for reference. The actual project situation still needs to be further comprehensively evaluated and implemented in combination with specific operating conditions, site conditions and other factors.
