AVTM Tunneling Hose Reel

AVTM hose reels are specially designed and manufactured for feeding mobile power systems. The feeding is done by hoses that carry air, water or other fluids to machines operating in tunnels, in yards or in harsh environmental conditions. Therefore AVTM hose reels are integrated into other machines as a component. For this reason it is usually controlled by the machine it is integrated into; it can be equipped with an independent control panel on request.
