Drive frame for an elevator installation

摘要

An elevator installation comprises a drive frame and a drive unit, wherein a support element couples an elevator cage with a counterweight, wherein a drive roller and a spacer roller are mounted at the drive frame on a mounting device associated therewith, wherein the support element is guided over the spacer roller of the drive roller, wherein at least one of the mounting devices is fixable to the drive frame at at least two positions so that a horizontal support element spacing is thereby variable and wherein a portion of the support element between the drive roller and the spacer roller is substantially linear.

1. An elevator installation, comprising:
a drive frame, the drive frame configured as a triangle having a horizontally extending base portion adapted to continuously extend between two vertices of the triangle substantially parallel to a load surface on which the drive frame is affixed; a drive unit; an elevator cage; a counterweight; a support element coupled to the elevator cage and the counterweight; a drive roller, the drive roller being mounted at the drive frame on a first mounting device; a spacer roller, the spacer roller being mounted at the drive frame on a second mounting device, the support element being guided over the spacer roller and the drive roller, a first segment of the support element between the spacer roller and the drive roller being substantially linear, the first mounting device or the second mounting device being fixable to the drive frame at two or more positions to provide a variable spacing between the first mounting device and second mounting device, the two or more positions being arranged along a line substantially parallel to the first segment of the support element between the spacer roller and the drive roller; and the support element comprising the first segment and a second segment arranged at the drive roller and extending substantially linearly to form an acute angle between the segments.
