How do Elevators Work

Roped Elevator: Traction ropes go around a motorized sheave. The sheave, a pulley with grips around the circumference, hoisting the attached elevator cab up and down. The other end is connected to counterweights with equally load of approximately 40% elevator occupancy. This balance allows for optimal energy use so the motor just needs to tip the balance one way or another using the POTENTIAL ENERGY. Both the elevator car and counter balance run along guide rails along the side of the elevator shaft. Breaks along the guide rails work as a redundant safety measure. Additional safety measures include floor counter (governor switch) with built in breaks on the cab, the specialty metal ropes 4x strong, and electromagnetic brakes that engage when the car comes to a stop. The electromagnets keep the brakes in the open position, instead of closing them. With this design, the brakes will automatically clamp shut if the elevator loses power.
