An elevator that travels faster up when fully loaded is classified as what type of compounded elevator?

A compounded elevator that travels faster when fully loaded is classified as over-compounded. This means that the elevator's design is such that it has a higher speed under a full load compared to its speed when it is empty. In practical terms, an over-compounded elevator utilizes a system where the force or torque generated by the motor exceeds what is merely necessary to lift the load at a standard speed, resulting in increased velocity when the load is at its maximum.

This characteristic is important in elevator design and operation because it can enhance the efficiency of transporting heavy loads. The term over-compounded relates directly to how much excess speed or capabilities the system has in its design as compared to merely balancing the load and speed.

Understanding this classification helps engineers and technicians ensure that elevators have the appropriate capabilities based on expected use cases, thereby optimizing performance, safety, and reliability in real-world applications.
