Abstract
An elevator installation includes a drive unit moving a car and a counterweight in an elevator shaft. The drive unit has a drive motor and a brake coupled to a drive shaft and mounted on a crossbeam in the elevator shaft or on the shaft ceiling. The drive unit has two spaced-apart drive zones and the drive motor is arranged to the left or the right of the two drive zones with the brake on the same side or the opposite side of the drive zones.
Claims24
An elevator installation comprising:
- an elevator car movable along one or more car guide rails;
- a crossbeam attached to an upper end of at least one of the car guide rails;
- a counterweight movable along one or more counterweight guide rails;
- a drive unit including a drive motor, a shaft driven by the drive motor, and a brake coupled to the drive shaft, wherein the drive unit is mounted on a support platform having a support member, the support platform being mounted to an upper end of one of the car guide rails, wherein the drive unit is mounted on a generally horizontal top surface of the support member, the support platform further comprising a rear wall and a pair of opposing sidewalls extending downward from the support member, the support member, the rear wall and the sidewalls forming a three-dimensional support structure below the drive unit and positioned generally above the crossbeam, wherein each sidewall is formed with a linear taper, with a greater width at an upper end of the sidewall in relation to a width at a lower end of the sidewall;
- and
- said shaft having at least two drive zone portions, each drive zone portion located on a respective opposite side of at least one of the car guide rails attached to the crossbeam and operable to engage a driving element coupled to the elevator car and the counterweight.
