Mobile concrete pump Adroit 420H

for tunnelundergroundfor underground mining

Overview
Adroit 420H is the smallest self-propelled wet shotcrete machine within the 4×4 group. It can easily reach points in tunnels and mines that large machines fail to reach. Fully designed according to site conditions with a simple design that allows on-site maintenance by 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 and a compressor on the platform. Standard pumping capacity is 22 m³/h.

Key features

• 22 m³/h shotcrete pumping capacity
• 8.4 m lateral reach, 9.3 m vertical reach
• 6 m³/min compressor capacity
• Perkins 74.5 kW diesel engine
• Hydrostatic drive system

Drive and performance
Hydrostatic system allows the 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 ground conditions. It is an ideal choice for work sites where high speed performance is required and construction areas with difficult ground conditions.
