hoisting rope

This installation also has guides for the hoisting ropes, but they are electrically operated.

Eldracher salvaged those he could with his hoisting ropes.

They have woven steel cables called hoisting ropes that are attached to the top of the lift cabin and wrapped around the drive sheave in special grooves.

One interesting feature of the original installation was that the hoisting rope ran through guides to retain it on windy days to prevent it flapping and becoming damaged.

The hoisting rope winds upon one part as it unwinds from the other, and a pulley sustaining the weight to be lifted hangs in the bight of the rope.

Today, the expo is also remembered as the place where Elisha Otis demonstrated an elevator equipped with a device called a safety, which would kick in if the hoisting rope broke.

Drum hoists are mounted on concrete within a hoistroom, the hoisting ropes run from the drum, up to the top of the headframe, over a sheave wheel and down where they connect to the conveyance (cage or skip).

The tailropes and weights offset the need for the motor to overcome the weight of the conveyance and hoisting rope, thereby reducing the required horsepower of the hoisting motor by up to 30%, with the overall power consumption remaining the same.

Founded in Yonkers, New York, USA in 1853 by Elisha Otis, the company pioneered the development of the safety elevator, invented by Otis, which used a special mechanism to lock the elevator car in place should the hoisting ropes fail.
