Mining Shotcrete Machine
UPS-20J(B) Mining Shotcrete Machine
UPS-20J(B) is a wet-mix robotic shotcrete carrier sized for narrow mine drives and small-section civil tunnels. A three-stage telescopic boom reaches 10.5 m and covers a 3 x 3 to 8 x 8 m cross-section, with the 4-5 m one-position jetting depth cutting how often the carrier has to be repositioned along the heading. The 1.8 m wide articulated four-wheel-drive chassis fits down development drives and decline ramps that wider rigs cannot enter; on-board screw compressor, accelerator-dosing hose pump and S-tube concrete pump make the machine self-contained at the face. Wired cabin and wireless remote control are standard. CRCHI Australia handles commissioning, parts and aftermarket support across Australia. For larger civil tunnel sections beyond the 8 x 8 m UPS-20J(B) envelope, the HPS-series shotcrete jumbo is the civil tunnel counterpart, with 30 to 50 m3/h pumping and working sections up to 31.4 x 17 m. The UPS keeps the narrow-drive footprint (1.8 m wide) that the HPS chassis cannot reach.
Features
Three-stage telescopic spray boom with 10.5 m maximum working height, 3 x 3 to 8 x 8 m cross-section coverage and 360 degree vertical / 240 degree horizontal nozzle articulation
20 m³/h maximum theoretical pumping capacity through an S-tube distribution valve, Φ140 / 800 mm conveying cylinder and 8 MPa maximum outlet pressure, fed from a 200 L hopper
Hose-pump accelerator dosing with electric proportional control - standard 500 L/h theoretical displacement, 840 L/h optional - accelerator dose tracks pumping speed for repeatable mix and rebound as low as 10%
Self-contained air supply: standard 37 kW screw compressor at 7 m³/min and 7 bar; optional 55 kW plateau-rated unit at 9.8 m³/min and 7 bar so spraying does not depend on external compressed air
Articulated four-wheel-drive chassis, 1.8 m overall width, 8.25-15NHS rubber tyres, wet axle with parking and service brakes; 36% maximum gradeability, inner 4.2 / outer 6.5 m turning radius and 13 km/h transport speed
Wired cabin control plus wireless remote up to 100 m, pumping-system automatic lubrication, hydraulic cable reel, full failure-alarm detection and reversing camera under a FOPS/ROPS certified canopy cab

Overview
Applications
Wet-mix sprayed-concrete ground support in development drives, declines, adits and crosscuts in non-ferrous underground mines, plus small-section civil tunnels working a 3 x 3 to 8 x 8 m profile. Suits sequenced excavation lining where one carrier handles drive-after-drive shotcreting at 1.8 m overall width. The wireless remote keeps the operator clear of the spray and rebound zone.
Performance
20 m³/h maximum theoretical pumping capacity at 8 MPa outlet pressure, 10.5 m maximum working height, 3 x 3 to 8 x 8 m operating cross-section, 360 degree vertical and 240 degree horizontal nozzle articulation. 12.3 t total weight on an 8200 x 1800 x 2715 mm articulated four-wheel-drive chassis, 5 km/h low and 13 km/h high tramming, 36% maximum gradeability, inner 4.2 / outer 6.5 m turning radius. 55.8 kW Yuchai China IV engine, 74 kW total installed power, 37 kW main motor and 37 kW air-compressor motor. Standard altitude rating to 2000 m.
Functions
Integrates a three-stage telescopic spray robot, S-tube concrete pump, hose-pump accelerator dosing, on-board screw air compressor, 200 L hopper, hydraulic cable reel and articulated four-wheel-drive chassis on one carrier. Wired cabin and wireless remote control, automatic pumping-circuit lubrication, reversing camera and full failure-alarm detection are standard.
Benefits
One operator runs the wet-mix shotcrete cycle from the cab or remote pendant, keeping the operator clear of the spray and rebound zone. Proportional accelerator dosing keeps layer thickness and early strength repeatable across the spray pattern, with rebound as low as 10%. The 4-5 m one-set-up coverage also cuts repositioning time across long advance shifts.
