Plow Horse Vs. Racehorse – Traction Elevators Explained

This traction elevator is one we toured at Elevator University.
Inspecting a traction elevator.

If the hydraulic elevator is the plow horse, always reliable over the long haul, moving at a steady jog, then the traction elevator is the racehorse. Like any thoroughbred, the traction elevator is designed for speed and distance. While hydraulic elevators are moved by pistons, traction elevators are moved by ropes and pulleys.

    1. Thanks Phil! You understand our goal well. Education is the key to safer, more cost effective vertical solutions. The more building owners and facility managers know the better informed decisions they can make! Thanks again.


  2. About geared traction, the gear is multiply the torque not the power. The power, due to the gear efficiency, il lower. The dimension of the motor (geared Vs. Gearless) is lower for geared due to the torque, not the power. Usually the power of geared motor is bigger, but dimensions smaller.

    About gearless and their efficiency, many and many gearless motor have lower efficiency than gearless. The gearless motor is efficeint if it is well designed, usually this bring to very heavy and big gearless motors.
