Turbosol TSR7

The TSR 7 is a tracked concrete spraying machine for underground work. It has two independent hydraulically driven rubber tracks with automatic negative parking brakes, allowing the machine to move entirely under its own power over rough and confined terrain. Four hydraulic support legs provide stability during spraying. The TSR 7 is easily connected to concrete pumps, and Turbosol points to the stationary Beton Master and TB 30 pumps, which can be supplied with an integrated dosing pump for admixtures. Thanks to the powerful telescopic boom and compact design, the machine can be used for both dry-mix and wet-mix spraying.

The spraying boom is telescopic with four sections, three of which telescope, and has a stroke of 3 metres with proportional control. The reach is up to 8.80 metres vertically and 7.70 metres horizontally, while the minimum reach is 2.5 metres vertically and 2.4 metres horizontally. The spray head rotates 360 degrees and can be tilted 240 degrees, with a Ø 45 mm nozzle. Two 15 W LED floodlights illuminate the work area, and the machine is operated by proportional remote control via radio or cable.

The TSR 7 has a dual power supply and can run either on the 18.5 kW three-cylinder Kubota diesel engine (Tier 4 / Stage V) or on a 7.5 kW electric motor. This means the machine can also work where access to electricity is limited. Travel drive is hydrostatic with two speeds of 1.5–3 km/h. The diesel tank holds 43 litres, the hydraulic oil tank 46 litres, and the electrical system is 12 V / 77 Ah. The machine measures 410 × 120 × 210 cm and weighs 2,210 kg. The bodywork protects the mechanical parts, and two wide side doors give quick access for inspection and servicing.
