The most suitable elevator car decoration

　　 Nowadays, domestic high-end villas and high-rise building projects continue to emerge, and the number of elevators has increased rapidly, which has brought market demand for elevator car decoration projects. Therefore, in some high-end residential villas, office buildings, hotels, guesthouses and other places, owners will have higher and higher requirements for elevator decoration. Tissot Elevator reminds elevator users and renovation and maintenance units that need to pay attention to is that the car decoration will increase the weight of the car, which will lead to changes in the balance relationship and traction conditions of the elevator. Correspondingly reduce the actual load capacity of the elevator, so that it has little impact on the normal operation of the elevator. After some units have decorated the elevator car, they still operate according to the rated load, which brings some unfavorable factors to the normal operation of the elevator. Over-decoration may even bury serious accident hazards, which will affect the elevator's traction wire rope, traction machine, safety gear, brake, etc., resulting in a greatly reduced service life.

　　 Impact on elevator balance coefficient

　　The balance factor is an important performance index of the traction drive elevator. The counterweight can partially balance the weight of the car and the load in the car, and reduce the load of the traction motor. Since the load in the car is constantly changing, and the counterweight has been fixed after the elevator is installed and debugged, and cannot be changed at any time. In order to make the operation of the elevator basically close to the ideal equilibrium state, it is necessary to choose a suitable one. Balance factor.

　　 Impact on the braking performance of elevator safety gear

When the safety gear stops the car, due to the kinetic energy of the car, the car and the wedge or clamping piece move relative to each other, and the wedge or clamping piece deforms the clamp body while clamping the guide rail. So as to absorb energy. When selecting the safety gear configuration, the maximum allowable total mass corresponding to the maximum operating speed should be calculated according to the operating speed of the overspeed governor and the amount of energy that the safety gear body can absorb. Only safety gears within the total allowable mass range are selected. In order to ensure the stopping performance of the safety gear. According to the requirements of GB7588-2003, when selecting safety gear, in addition to adopting the appropriate safety gear form (instantaneous or progressive) according to the rated speed of the elevator. It is also necessary to consider the maximum allowable total mass of the elevator when it is applied to the maximum operating speed.

In summary. For elevators that require elevator car decoration renovation, they should be carried out by a manufacturer or a qualified unit according to the requirements of elevator renovation. When carrying out technical transformation, clarify the design value of the elevator balance coefficient, the design parameters of the car, the parameters of the elevator car, etc., and a written accounting should be made to ensure that the elevator operating parameters meet the safety requirements.
