  • Elevator pressure traction arrangement
    Patent number: 6742627

The traction device applies a load normal to a driving sheave that biases the elevator rope or belt against the sheave. The tension device preferably includes a plurality of rolling members that move about their axes responsive to relative movement between the driving sheave and the rope or belt. A traction belt rides upon the rolling members and the traction belt engages the rope or belt to bias it against the driving sheave with a preferably distributed force.
