Definitions
- the present invention relates to an elevator apparatus including a safety device for ensuring the safety of an elevator maintenance worker.
- an elevator maintenance worker rides on a car that moves up and down in the hoistway and performs maintenance and inspection work on the elevator equipment installed in the hoistway. For this reason, maintenance work can be performed even when the force is stopped at the top so that maintenance personnel who are performing maintenance work do not collide with the hoistway ceiling surface. In general, sufficient space is secured. However, in elevator devices that respond to the recent demand for space saving, such as machine room-less elevator devices in which elevator equipment is arranged in the hoistway, the force stops at the top. In addition, there are some cases where sufficient space necessary for maintenance work cannot be secured above the car. In such an elevator apparatus, in order to ensure the safety of maintenance workers, a safety apparatus that mechanically restricts the rise of the car during elevator maintenance work is installed.
