GAD-2 battery locomotive is a machine equipped with an innovative zero emission battery drive. The locomotive is composed of up to four hydraulic drive modules. The drive is implemented with a brushless three-phase synchronous electric motor with permanent magnets powered through an inverter from a battery pack and a hydrostatic transmission in a closed system. The hydraulic unit powers slow-speed hydraulic motors of the drive modules. Drive transfer from the hydraulic motors to the monorail track is implemented through a frictional coupling of the drive wheels with the friction line of the track or through a shape coupling of the cog wheels with the toothed line of the track.
It is designed for personnel transport on inclinations up to ± 25° and material transport on inclinations up to ± 30°. It can travel on the suspended friction tracks of the approved type (based on the I155 -bars) currently used in mines or along a dedicated cog wheel tracks. Friction and cog wheel tracks can be joined using a special drive change track. Transfer from friction to cog wheel drive and reverse is automatic.
A zero emission locomotive is a solution with substantial impact on the increase of work efficiency, safety and comfort in personnel and heavy, large-size material transport.
