Inspecting elevator systems regularly is critical to ensuring that they continue operating as they should and that their safety mechanisms work properly. One type of inspection that is essential for elevator safety is the load test.
What is an elevator load test? This is a safety procedure that ensures an elevator’s load and speed ratings remain accurate over time.
What Is Elevator Load Testing?
All elevators have a maximum load capacity that is stated inside the elevator car. They also have maximum speed ratings, which indicate the highest speed at which the elevator can safely transport the maximum load.
Elevator load testing ensures that an elevator is continually able to meet both of these maximum ratings. For example, if an elevator’s capacity is rated at 2,000 pounds, load testing ensures that this figure remains accurate long-term. If an elevator can no longer meet the load and speed maximums, it will require servicing from a trained technician.
How Are Elevator Load Tests Performed?
An elevator engineer performs weight capacity testing by loading the car to 25% above its highest rated capacity. For example, if an elevator’s maximum weight is rated at 2,000 pounds, the engineer will test the car at 2,500 pounds. They will then run the elevator to ensure that all safety mechanisms are working properly, including the automated brake system that should kick in if the car exceeds the weight rating.
The engineer will also test the elevator without any load. Modern elevators often contain reinforced steel or granite panels that add weight to the car on their own. This test ensures that the engineer can rate the elevator for the proper amount of additional weight rather than the gross weight.
During this elevator safety inspection, the engineer will observe the elevator’s speed, stopping accuracy, and brake engagement. These tests are distinct from pressure tests, which are hydraulic elevator tests that should be performed annually to check the system’s pressure.
The Importance of Elevator Load Testing
Modern elevators should have load testing performed at least once every five years. This testing serves several purposes in elevator safety:
- Identify potential problems early: Load testing enables engineers to identify minor issues with the elevator operation before they escalate into major problems.
- Prevent equipment failure: It is much better for an elevator to fail during a load testing than during a ride with actual occupants. Elevator load testing allows engineers to identify issues before the brakes or other equipment fail during a ride.
- Meet code compliance standards: Load testing is one of many elevator maintenance requirements necessary to remain compliant with state and federal regulations and meet elevator certification standards.
