The TSV 3-6 tunnel snorkel distributor is a concrete placing and distributing system for large-scale formworks. The TSV unit rides on rails set into the tunnel formwork and can turn the telescopic snorkel pipe 360° rectangular to the formwork axle. The snorkel system is driven by an own power pack with 7,5 kW. The unit is linked to an scissor pipe system (125 mm diam.) which also rides on rails. The tunnel snorkel can supply a length of 8,5 m without putting in or off any concrete pipe. The driving langth can be increased by additional scissor pipes on request.
