Sprayed concrete for tunnels, mines and slopes
The Schwing Top Shot Runner is a self-propelled wet-shotcrete machine: a concrete pump, a spraying boom and an accelerator dosing system on one carrier.
TSR 30.14 Mark II
Built for rugged tunnel sites. The telescopic boom places the nozzle anywhere within a 14 m vertical reach, while the operator works by radio remote from wherever the view of the surface is best.
- Boom reach of 14 m vertical and 11 m horizontal, with 330° rotation
- Schwing concrete pump with the ROCK Valve, for stiff, low-water mixes
- Accelerator dosing matched automatically to the concrete output
- Hydrostatic four-wheel drive with front, four-wheel and crab steering
- Pump and boom run on an electric motor; a diesel engine drives the carrier
One machine, one operator
Spraying boom
A compact telescopic boom on a slewing ring, with self-locking valves on the lifting and telescopic cylinders so it holds position.
Spraying head
The nozzle rotates 360°, tilts 270° and slews 360°, so it can stay square to the surface for an even layer and less rebound.
Concrete pump
A Schwing pump with the ROCK Valve. Its fast switchover gives a nearly continuous flow at the nozzle.
Accelerator dosing
A screw-type dosing pump under PLC control doses accelerator in step with the concrete output and shows target and actual values on screen.
Radio remote control
Pump on and off, boom, nozzle and accelerator percentage are all on the wireless remote, with a cable back-up.
Built for tunnels
On-board cable reel, high-pressure water washer, work lights, two hydraulic outriggers at the boom end and a 1,000 L accelerator tank.
