What are elevator guide boots?

The nylon block between the elevator guide rail and the car can slide is called the elevator guide boot. It can fix the car on the guide rail, so that the car can only move up and down. The upper part of the guide boot and the oil cup reduce the friction between the boot liner and the guide rail. 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.

Elevator guide boots by guide boots head, guide boots body, guide boots seat, etc. 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.

Types of elevator guide boots:

Elevator guide boots are divided into roller guide boots and sliding guide boots.

1, roller guide boots with 3 or 6 wheels stuck on the track is generally used for the speed of 2 meters above the elevator. Its characteristics are: to roll friction instead of sliding friction, reduce friction loss, reduce the vibration and noise in operation, improve the comfort of riding, but the boot processing and installation requirements are relatively high.

2, fixed sliding guide boots is a chute card (concave groove) on the track, generally used for the speed of the elevator below 2 meters. Sliding boot features: because the boot head is fixed dead, and the structure is simple, there is no adjusting mechanism, with the increase of the elevator running time, the boot and guide rail with the gap will be more and more large, the car in the operation of shaking, and even impact.

Installation of elevator guide boots:

The installation method of guide boots is to put them on the installation position of the guide rail of the cage frame. After finding the correct position, fix them on the guide rail of the cage with bolts.

The installation of elevator guide boots must meet the following requirements: 1, the upper and lower guide boots installed in place, should be on the same vertical line, do not allow skew, deflection, ensure that the upper and lower guide boots and safety jaws center three points into a line. 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.
