A method of mounting a support belt in an elevator installation, wherein mounting steps are carried out in several elevator shaft regions from a work platform having car deflecting rollers, comprising the steps of:
- a. positioning the work platform in a lower region of the elevator shaft;
- b. leading the support belt around the car deflecting rollers;
- c. storing remaining portions of the support belt at the work platform;
- d. fastening a first end of the support belt to a first connecting point;
- e. leading a second end of the support belt around a traction pulley;
- f. leaving a loop of the support belt in the lower region of the elevator shaft;
- g. connecting a counterweight deflecting means with a counterweight at the loop;
- h. attaching the second end of the support belt to a second connecting point;
- and
- i. providing a track-jumping protection means at the car deflecting rollers, the track-jumping protection means protecting the support belt in radial direction and a lateral direction against jumping a track of the car deflecting rollers, and mounting the track-jumping protection means when the work platform is located in the lower region of the elevator shaft for the purpose of support belt installation.
