Parts of an Elevator That Require an Annual Inspection

When it comes time for your annual NYC elevator inspection, you might not know what the inspector is looking for. Elevators have a lot of electrical and mechanical parts, and they must all be inspected. The inspector will check both the parts and their functionality. These are three of the major categories of parts and functions that the inspector will check.

Operations and Functions

There are two types of operations and functions examined by elevator inspectors. The firefighter functions are one of the two categories. The elevator must be fully operational on all of the firefighter functions. The second category is standby power operation. If the building’s main electrical source goes out, so does the elevator’s. The elevator must have a standby power supply for the safety of the passengers. The standby power illuminates the car and allows passengers to call for help.

Limits

Inspectors test two types of limits for freight and passenger elevators. One of the limit types examined is the normal limit. This refers to the elevator’s movement when it goes up or down. There is an up normal limit and down normal limit switch around the landing of each floor. The final limit switches also have top and bottom units for each floor. This stops the elevator’s movement past a safe place for the landing.

Safety Devices

In addition to the limit switches, there are other safety devices that the inspector will check. Some of these devices are electrical, and others are mechanical. Some of the safety devices include the emergency stop switch, emergency brake, fire shutters, governor, governor rope, over-speed valve, safety cable and the seismic switch. Some of the other parts of the elevator also function as safety devices as well as routine operating parts, including the micro lights, safety housings and edge components.
