Abstract
An elevator has an elevator car supporting frame that can travel in a travel space provided for a journey of the elevator car supporting frame. The elevator installation is also provided with a first elevator car and a second elevator car arranged on the elevator car supporting frame. Furthermore, a hydraulic moving element is arranged in a lower end region of the travel space. In this way, the first elevator car can be moved in relation to the second elevator car, by the moving device, in the lower end region of the travel space.

An elevator installation has an elevator car support displaceable in a travel space provided for travel of the elevator car support, a first elevator car arranged on the elevator car support, and a second elevator car arranged on the elevator car support, comprising:
- an adjusting device arranged below a lower end region of the travel space, wherein the adjusting device is a hydraulic adjusting device that includes a piston rod, a cylinder, and a pump, the piston rod configured to move in two directions by means of the pump and a pressurized fluid in the cylinder;
- and
- the first elevator car being selectively movable relative to the second elevator car, when the second elevator car is fixed in the travel space, wherein in the lower end region of the travel space the piston rod of the adjusting device engages and moves the first elevator car relative to the second elevator car in a direction of travel of the elevator car support in the travel space and the first elevator car is disengaged from the adjusting device when the first elevator car is above the lower end region of the travel space.
An elevator installation comprising:
- an elevator car support displaceable in a travel space provided for travel of the elevator car support, the elevator car support having a first elevator car support part and a second elevator car support part movable relative to the first elevator car support part;
- a first elevator car arranged on the first elevator car support part and a second elevator car arranged on the second elevator car support part;
- an adjusting device arranged below a lower end region of the travel space, wherein the adjusting device is a hydraulic adjusting device that includes a piston rod, a cylinder, and a pump, the piston rod configured to move in two directions by means of the pump and a pressurized fluid in the cylinder;
- and
- the first elevator car being selectively movable relative to the second elevator car when the second elevator car support part is fixed in the travel space and the first elevator car support part is in the lower end region of the travel space, wherein the first elevator car support part bears against the adjusting device permitting the adjusting device to move the first elevator car relative to the second elevator car in a direction of travel of the elevator car support in the travel space.
