Pneumatic Air Brake Trainer Manufacturer,Supplier and Exporter in India

Product Code : EL-AELE-9377
Jlab Export is a leading Pneumatic Air Brake Trainer Manufacturer,and suppliers in India

Trucks and buses brake with compressed air, not brake fluid. This trainer sets out original heavy-duty truck air brake components on two mobile floor stands, one for the truck and one for the trailer. Quick-connect air hoses let students join and change circuits during experiments, and a colour-coded schematic chart shows the layout.

Air Brake Practicals for Students

Students first follow the air path on the schematic, from the compressor and reservoirs through the foot valve to the brake chambers at the wheels. The sectioned Model of Air Brake System shows the inside of the compressor, unloader valve and foot valve. With that picture in mind, they connect the hoses on the trainer and apply the brakes.

On the trailer stand, students see how the trailer is fed and controlled through its own lines and what happens when the supply is lost. Routine checks follow: pressure build-up, leakage with the brakes applied, the low-pressure warning and draining the reservoirs. The Air Brake Actual Working unit then shows the shoe and drum end of the system.

Frequently Asked Questions

How does an air brake apply the wheel brakes?
The foot valve sends reservoir air to the brake chambers in proportion to pedal travel. In each chamber the air pushes a diaphragm and push rod. On drum brakes this turns the slack adjuster and cam, which force the shoes against the drum.

Why are there separate truck and trailer stands?
A trailer has its own reservoir and brakes, fed from the truck through couplings. Two stands let students connect and disconnect the trailer side much as they would when coupling a real trailer, and study each half on its own.

What does the governor or unloader do?
It keeps reservoir pressure within a working band. At the cut-out pressure the compressor is unloaded and stops charging the system. When pressure falls to the cut-in point, it starts charging again.

Why must the air reservoirs be drained?
Compressed air carries moisture and some oil from the compressor, and these collect in the reservoirs. Water left in the system can corrode valves or freeze in cold weather, so the tanks are drained as a routine check.

What are the quick-connect hoses for?
The air hoses use a quick connection system, so circuits can be joined, changed and taken apart quickly. This keeps practical time for the experiment itself rather than for fitting pipework.
