When we look at an elevator, it is hard to imagine that there are so many different types available out there. The elevator itself was invented many years ago originally as a pully machine operated by slave labour. Over the years, technology advanced thanks to a man called Elisha Otis who secured the cars and prevented them from falling mid journey. In the second part of this blog series, we’re going to go over geared and gearless traction elevators…

Traction Elevators: These are a type of elevator which is lifted by ropes. These ropes pass over a wheel that is attached to an electric motor located above the shaft of the elevator itself. Their main use is mid and high rise jobs and they are able to travel at a much fast speed than hydraulic elevators. A counter weight is employed in order to offset the weight of the cab and any people inside it, thus making the elevator more efficient. This is due to the motor not having to move as much overall weight.

Geared Traction Elevator: In these designs, a gearbox is found attached to the motor that is used to operate the wheel and thus, move the ropes. They are able to travel at speeds of 500 feet per minute, with a minimum travel distance of 250 feet. In terms of maintenance and energy, a geared traction elevator is considered average compared to other designs.

Gearless Traction Elevators: The wheel mentioned above is attached directly onto the motor is this design. In fact, gearless traction elevators are able to travel at speeds of up to 2,000 feet per minute which makes them the perfect choice for high rising buildings. With a high initial cost, gear less traction elevators operate much more efficiently than other designs which make them a brilliant investment.
