Track chassis

Steel tracked chassis and rubber tracked chassis are the two most advantageous products in our industry!

Domestic crawler chassis can be roughly divided into two types: a rubber crawler chassis and a two-steel crawler chassis.

A: Rubber rubber tracked chassis is suitable for small light industry and small construction machinery industry. Light industry is generally agricultural machinery within one to four tons. The construction machinery industry is mostly used in the small drilling industry. The choice of working environment is as follows:

(1) The temperature of the rubber crawler is generally between -25 and +55'C.

(2) The salt of chemicals, engine oil and seawater will accelerate the aging of the track. After use in such an environment, the track should be cleaned.

(3) Road surfaces with sharp protrusions (such as steel bars, stones, etc.) can cause rubber tracks to be injured.

(4) The edge stone, rut or uneven road surface of the road will cause cracks on the ground side pattern of the track edge. This crack can continue to be used without injuring the steel cord.

(5) Gravel and gravel pavement will cause early wear of the rubber surface in contact with the load-bearing wheel to form a small crack. In severe cases, moisture invades, causing the core iron to fall off and the steel wire to break.

Second: the range of steel track used and its life and the choice of working conditions is wider.

It consists of a steel crawler, a running wheel, a guide wheel, a roller, a chassis and two travel reducers (the travel reducer consists of a motor, a gearbox, a brake, and a valve body). Generally, for example, the rig is arranged on the chassis as a whole, and the walking speed of the crawler chassis is adjusted by the control handle, so that the whole machine can realize convenient movement, turning, climbing, walking, and the like.

Automatic Sliding Door

Automatic Sliding Doors can either be a single door sliding in one direction or bi-parting doors where each door leaf slides in the opposite direction. They are often used in grocery stores, entrances to shopping malls, hospitals and other applications where you want to provide your customers a hands free, safe and easy access to your building.

Hospitals

Airports

In addition, one of the biggest benefits of automatic doors is energy savings. Since these doors only open when someone comes in or out of your building, it prevents the loss of energy when a door may otherwise be left open for a long time.
