Suspended Railway GAD-2 is designed for personnel transport on inclinations up to ± 25° and material transport on inclinations up to ± 30°. It can be operated in underground excavations of mining facilities, in methane and non-methane environment, including headings with “a”, “b” or “c” methane explosion hazard degree and class A and B coal dust explosion hazard. If the concentration of methane in the surrounding atmosphere exceeds 2%, the Railway will be automatically turned off until the concentration of methane decreases to acceptable level. Suspended Railway GAD-2 is configurable with 2, 3 or with 4 driving carts, depending from the required pulling force. In addition, it can be used in the configuration called "fixed" or "unhooked". Railway GAD-2 is designed to transport personnel and material along suspended, friction or rack rails, with inclinations up to 30°. The Railway driving carts have built-up cog wheels above the friction wheels, through which the device can generate more tractive force at a reduced driving speed GAD-2 is equipped with driving trolleys driven by hydraulic motors and a hydraulic unit that powers them.
