PNEUMATIC AIR BRAKE TRAINER Description and Specifications for Lab Tenders
The
Pneumatic Air Brake Trainer should provide a comprehensive system whereby the
student may study and understand the principles, operational theory and
maintenance of air brake systems found on trucks or large vehicles. The unit
should consist of original International branded heavy duty truck pneumatic
braking components, which should be mounted onto separate (Truck and Trailer)
integrated floor stands, made from powder coated electro galvanized steel, that
are mounted onto wheels for mobility. Air hoses should have a quick connection
system, allowing for easy connections and experiments. A color coded schematic
chart, under a lexon polycarbonate protective screen, of the brake system and
circuit’s, should also be mounted onto the trainer for reference.
PNEUMATIC AIR BRAKE TRAINER, AUTOMOTIVE LAB.
Specifications:
1. Components
A. The trainer should provide a system whereby the student may study and understand the principles of the theory and operation of compressed air brake systems as commonly found on trucks.
B. The trainer should consist of original functional components, which are mounted onto a large board that is fitted with a wheeled stand for mobility.
C. The trainer should have two boards, one for the truck system and one for the trailer system. Each of the components should be fitted with a pneumatic quick connect/disconnect system so that the students may quickly connect the system and components in a variety of configurations.
