One kind of elevator apparatus with no machine room

One inventive disclosure roomless elevator apparatus comprising a hoisting machine, a car, a counterweight, at least one guide wheel, a set of hoisting ropes and a control cabinet, which suspension ratio of 1: 1, wherein the hoisting rope, the hoisting ropes composed of a main body and a plurality of elastomeric resilient body and disposed in said body parallel with the hoisting ropes a separate carrier configuration. Elevator apparatus of the present invention by increasing the traction coefficient of friction, wrap angle is reduced, and reducing the diameter of the traction sheave and the guide wheel, so that the overhead as small as possible, so that no room 1: 1 elevator structure having practical value. The elevator apparatus further controlled by the elastomeric material of the outer layer of the hoisting ropes traction coefficient of friction, so as to control wrap angle, by controlling the hoisting ropes and the traction sheave guide structure control wheel diameter, greatly reduces the overhead in two ways.
