Research and Application of the Electromotion Elevator for Mechanized Workover Progress

The elevator being used in field application causes several problems such as low level of mechanization and high intensity of labor. Therefore, electromotion elevator is developed and tested in this paper, which works with mechanized workover equipments. On the base of traditional elevator, the safety pin for the rings is driven by a spring and its own gravity, while the door of the elevator, with self-locking function, is driven by a DC motor which is remotely controlled. Through the field test and application, the electromotion elevator shows desirable safety, reliability and continuous working ability, which satisfy the requirement of workover operation.
