The diameter ratio of the wheel bolt is 50 (applicable to the load Q ≤ 1050Kg), which is 25% higher than the national standard requirement of 40). The service life of steel silk has been extended by more than 2 times, giving consideration to safety and service life, and reducing elevator maintenance costs.

The strength test of landing door is higher than the national standard. Through the strength test of 45kg pendulum freely released from the height of 1100mm (800mm as required by the national standard) to knock out the landing door, it can effectively deal with the risk of reckless knocking out and prevent passengers from falling into the hoistway.

The car accidental movement protection device can prevent the car from moving unexpectedly without instructions in the door opening area, prevent the risk caused by the car accidental movement, and protect the safety of passengers.

The anti looseness detection of the traction rope ensures the safety of the elevator. The traction rope anti loose detection device detects the whole process in real time. When the traction rope is loose, the elevator will stop running immediately to ensure the safety of the elevator.

Whole process accurate weighing technology, overload alarm reminder. The use of industry-leading full range weighing technology can accurately measure the car load of each landing, avoiding potential safety hazards and accidental injuries caused by overloading.

The new door lock electrical design prevents the risk of door lock short circuit. Prevent the electrical circuit of the elevator door lock and the door lock switch contact from being artificially short circuited to cause the elevator to run when the door is open, so as to avoid the risk of accidents.
