Abstract
The invention relates to an elevator arrangement with multiple elevator cars in the same elevator shaft, the arrangement at least an uppermost elevator with its operating system, hoisting machinery and elevator car, and a lowermost elevator with its operating system, hoisting machinery and elevator car, which elevator cars are arranged to run in the same elevator shaft along the same guide rails. The types of the two elevators in the same elevator shaft are mutually different from each other.
Claims12
An elevator arrangement with multiple elevator cars in an elevator shaft, the elevator arrangement comprising:
- an uppermost elevator including a first control system, first hoisting machinery and a first elevator car, the first hoisting machinery including a hoisting rope connected between a top of the first elevator car and a first counterweight via a traction sheave, the hoisting rope configured to both suspend and move the first elevator car in the elevator shaft between a lowermost floor and an uppermost floor, and
- a lowermost elevator including a second control system, second hoisting machinery and a second elevator car, the second hoisting machinery including suspension ropes and a traction member, the suspension ropes configured to suspend the second elevator car via diverting pulleys above the first elevator car and the traction member connected between a bottom of the second elevator car and a second counterweight via a drive wheel below the second elevator car to move the second elevator car in the elevator shaft between the lowermost floor and the uppermost floor such that the first elevator car and the second elevator car run along same guide rails while the first elevator car and the second elevator car utilize different types of suspension systems.
An elevator comprising:
- elevator cars configured to move on same guide rails in an elevator shaft, the elevator cars including a first elevator car arranged above a second elevator car with respect to a bottom of the elevator shaft, the first elevator car and the second elevator car connected to first hoisting machinery and second hoisting machinery, respectively, wherein
- the first hoisting machinery including a traction sheave connected to a top of the first elevator car and a first counterweight via a hoisting rope, the traction sheave configured to support the first elevator car, and
- the second hoisting machinery including diverting pulleys above the first elevator car in the elevator shaft and a drive wheel below the second elevator car, the drive wheel connected to a bottom of the second elevator car and a second counterweight via a traction member such that the second elevator car is supported by the diverting pulleys and moves in response to movement of the drive wheel.
