Catalog excerpts

Adroit 420H4x4 Shotcrete Machine Adroit 420H is the smallest self-propelled wet shotcrete machine within the 4x4 group. Adroit 420H, can easily reach points in tunnels and mines that large machines fail to reach. Adroit 420H fully designed according to site conditions with a quite simple designs ensures the benefit of being maintained at the work site through the user. The rigid chassis has 4 wheel drive and 4 wheel steering. Machines are fully equipped with telescopic boom system, rotation group, water & admixture pumps and tanks, energy cable reel, compressor on the platform. Standard pumping capacity is 22 m3/h. Hydrostatic system allows user to have max. speed - max. torque by variable flow pump and hydromotor. Gear options can be chosen as fast or slow according to road and land conditions. Ideal choice for work sites where high speed performance is required and construction areas, which have difficult ground conditions.
