Research on Auxiliary Test Device for Elevator Balance Coefficient

As an important parameter of elevator, elevator balance coefficient directly affects the safety and comfort performance of traction driven elevator. According to the requirements of GBT 10059–2009, the balance coefficient of traction driven elevator shall be in the range of 0.4-0.5. After the installation of the elevator, the balance coefficient will be tested. If the number of counterweights is not increased or reduced for a long time, the balance coefficient of the elevator will not change significantly. The current inspection specification TSG T7001-2009 stipulates that the balance coefficient test method is mainly through the current load curve method. This method needs to carry the weight repeatedly, measure the change of motor current, and obtain the specific value of balance coefficient by fitting the current and load curve. However, this method has high labor intensity and long operation time, requires frequent handling of weights and high labor intensity for operators. Therefore, this paper designs an auxiliary test device for elevator balance coefficient, which can solve the technical problem of moving weights frequently.
