Method for constructing an elevator, and elevator

A method for constructing an elevator, comprising:

• providing a base for the elevator;
• positioning a lifting device on the base;
• wherein the lifting device has several independently-controllable individual lifters which are positioned on the base;
• raising an upper component of the elevator by way of the individual lifters of the lifting device;
• positioning a lower component, which is to be arranged underneath the upper component, under the raised upper component;
• lowering the upper component onto the lower component by way of the lifting device;
• after lowering the upper component onto the lower component by way of the lifting device, the lower component is raised together with the upper component, as jointly-raised components, by way of the individual lifters of the lifting device, and a further lower component is subsequently positioned under the jointly-raised components, whereupon the jointly-raised components are lowered onto the further lower component by way of the lifting device;
• and
• removing the lifting device from the base,
• wherein the raising and/or lowering of the upper component and the raising and lowering of the jointly-raised components by way of the individual lifters is synchronized by way of a synchronizing device, whereby each lifter is controlled individually by the synchronizing device, and
• wherein a vertical orientation of the elevator is monitored by way of a sensor system or sensor device, and the vertical orientation of the elevator is controlled before further raising and lowering of additional components.
