An elevator system includes an elevator car movable in an elevator shaft, a suspension means extending in the elevator shaft, a drive machine associated with the suspension means and a controllable coupling apparatus arranged on the elevator car. The suspension means has a coupling element that the coupling apparatus can be coupled to by assuming a coupled position and from which the coupling apparatus can be uncoupled by assuming an uncoupled position, as a result of which a drive connection between the elevator car and the suspension means can be established and released. The elevator system has a securing device that can assume a securing position and a release position and that, in the securing position, secures the coupling apparatus in the coupled position against leaving the coupled position.

An elevator system includes an elevator car movable in an elevator shaft, a suspension means extending in the elevator shaft, a drive machine associated with the suspension means and a controllable coupling device arranged on the elevator car. The suspension means has a coupling element that the coupling device can be coupled to and uncoupled from, as a result of which a drive connection between the elevator car and the suspension means can be established and released. The elevator system has a guide system guiding the coupling element during a movement in the elevator shaft. The guide system has a guide that is stationary relative to the elevator shaft and a runner that is connected to the coupling element via a connection and is guided along the guide. The connection between the coupling element and the runner enables a relative movement between the runner and coupling element.

An elevator system includes a hoistway and an elevator car positioned in and movable along the hoistway. The elevator car includes a first sheave and a second sheave spaced apart from the first sheave. The first sheave and second sheave have parallel axes of rotation and each include a traction surface and a gearless prime mover operably connected to the traction surface to drive rotation of the traction surface. A first load bearing member is positioned in the hoistway and a second load bearing member is positioned in the hoistway. The first load bearing member passes laterally under the first sheave, vertically upward between the first sheave and the second sheave, and laterally over the second sheave. The second load bearing member passes laterally under the second sheave, vertically between the second sheave and the first sheave, and laterally over the first sheave.

An elevator system includes first and second elevator cars movable vertically in a first elevator shaft, a closed support belt routed around lower and upper deflection rollers, a drive machine driving the support belt, and an actuable coupling device arranged on each of the first and second elevator cars. The support belt has first and second coupling elements to and from which the coupling devices can be coupled and decoupled whereby a drive connection between the respective elevator car and the support belt can be established and released. A coupled elevator car is moved in the first elevator shaft by the support belt driven by the drive machine. The coupling elements are arranged such that they are not routed around the deflection rollers during movement of the first elevator car from a lower end position to an upper end position or vice versa.

An elevator system includes an elevator car that is movable in an elevator shaft in the vertical direction, a closed support belt guided about a lower deflection roller and an upper deflection roller and a drive machine driving the support belt. A drive connection is made between the support belt and the elevator car with a coupling device arranged on the elevator car that is coupled to a coupling element of the support belt. The coupling element is a connection element that connects two free ends of the support belt together.

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.

An elevator system comprising multiple elevator cabs operating independently in an elevator shaft. Each cab comprises a pair of underslung suspension cables, equally spaced apart from the center of the cab; a lift motor at a top surface of the shaft having an axle with a traction sheave at each end of the axle; each set of suspension cables connected at a first end to a hook at the top surface, engaging a pulley connected to a counterweight, engaging a first traction sheave, engaging a cab pulley, slung under the cab, engaging a second cab pulley and terminating at a second end connected to the top surface. Each set of four cab pulleys of each elevator cab is progressively and symmetrically located closer to the center of each cab, so that suspension cables, counterweights, pulleys, hooks, lift motors, axles, and traction sheaves will not horizontally or vertically conflict with each other.

An example elevator system may include a shaft in which a first elevator car and a second elevator car positioned below the first elevator car are separately movable up and down in a vertical direction along a common guideway. The first elevator car may be coupled to a first counterweight by first suspension ropes and by first compensation ropes, and the second elevator car may be coupled to a second counterweight by second suspension ropes and second compensation ropes. Further, first and second ends of the first compensation ropes may be secured to the first counterweight or to the first elevator car. The first compensation ropes may be guided around at least one roller positioned on a bottom surface of the first elevator car or on the counterweight.

The elevator car includes a first sheave and a second sheave spaced apart from the first sheave. The first sheave and second sheave have parallel axes of rotation and each include a traction surface and a gearless prime mover operably connected to the traction surface to drive rotation of the traction surface. A first load bearing member is positioned in the hoistway and a second load bearing member is positioned in the hoistway. The first load bearing member passes laterally under the first sheave, vertically upward between the first sheave and the second sheave, and laterally over the second sheave. The second load bearing member passes laterally under the second sheave, vertically between the second sheave and the first sheave, and laterally over the first sheave.
