TSR 7 can work either with the diesel engine or with the electric motor. This dual operation mode allows it to work even in areas with scarce power supply. Thanks to the sturdy telescopic boom with 4 sections, long reach and compact design, TSR7 can be used either for dry or wet shotcrete. Two wide side doors make every component accessible for fast maintenance and control operations. The perfect addition to TSR 7 are Turbosol Beton Master or TB 30 stationary concrete pumps which can be supplied with integrated admixture dosing pump.
