Sliding guide boots are nylon blocks that can slide between the elevator guide rail and the car, called guide boots, which can fix the car on the guide rail, so that the car can only move up and down, and the upper part of the guide boots and oil cup, reduce the friction between the boot lining and the guide rail.

Sliding boot definition

Each elevator car is installed with four sets of guide boots, respectively installed on both sides of the upper beam and under the car bottom safety clamp; Four pairs of heavy guide boots are installed at the bottom and top of the heavy beam.

The guide boots fixed ON the car can move up and down along the fixed guide rail installed on the wall of the well of the building to prevent the car from deflection or swing in operation.

Sliding boot construction

Installation of sliding guide boots

The installation method of sliding guide boots is to put them on the installation position of the guide rail of the cage frame, and fix them on the guide rail of the cage with bolts after finding the correct position. Installation of sliding guide boots must meet the following requirements:

1. After the upper and lower guide boots are installed in place, they should be on the same vertical line without any skew or deflection. Ensure that the upper and lower guide boots are aligned with the center of the jaws of the safety clamp at three points. Roller guide boot fixed guide boot

2. Fixed guide boots are mainly used for freight elevators. The gap between the two sides should be consistent, and the gap between the lining and the top surface of the track should be 0.5 ~ 2mm.

Type of sliding boot

Elevator guide boots are divided into rolling guide boots and sliding guide boots!

1. Rolling guide boots are used with 3 or 6 wheels stuck on the rail is generally used for the speed of 2 meters above the elevator!

Features: Rolling friction instead of sliding friction, reduce friction loss, reduce the vibration and noise in operation, improve the comfort of riding, but the processing and installation of the boot requirements are relatively high.

2. Fixed sliding boot is a chute stuck on the guide rail "is concave groove" is generally used for the speed of the elevator below 2 meters!

Features: Because the guide boot head is fixed dead, and the structure is simple, there is no adjusting mechanism, with the increase of the elevator running time, the guide boot and guide rail with the gap will be more and more large, the car in the operation of shaking, and even impact.

3. Elastic sliding guide boots are divided into spring sliding guide boots (suitable for rated speed less than 1.7m /S elevator) and rubber spring sliding guide boots (suitable for high speed elevator).
