Description

technical field [0001] The present invention relates to a safety device, in particular to a safety device for an elevator car. Background technique [0002] In high-rise buildings, for the convenience of transporting materials or personnel, a car that can run up and down is usually provided. The car is set in the elevator shaft. There are many ways for the car to move up and down in the elevator shaft. There are two traction wire ropes arranged vertically in the well, and a power device is provided on the car, which drives the car to move up or down along the traction wire ropes to complete the work of transporting materials or personnel. In many cases, such as equipment failure or aging, the car will suddenly fall, which can easily cause casualties and equipment damage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-drop safety device that can prevent the car from falling suddenly. [0004] The anti-f...
