WHP38H Tunnel Diesel-electric Concrete Wet Spray Bolting Shotcrete of Tunnel Hydropower Station Machine

The WHP38H is designed for wet-mix shotcrete (concrete wet spraying) and related bolting operations in tunnels, hydropower stations, mining and irrigation projects to improve productivity and site safety.

The machine uses a diesel-electric powertrain with total power rating of 96 kW. The motor is the core component driving the pumping and spraying systems.

Theoretical ejection capability is 38 m³ per hour. Actual throughput will depend on concrete mix, aggregate size, hose length, nozzle settings and site conditions.

Standard hose inner diameter is 80 mm.

Overall dimension is 8350 × 2700 × 3380 mm (L×W×H) and single gross weight is 14,400 kg. Single package size is listed as 835 × 270 × 340 cm.

Maximum travel speed is 19 km/h and minimum ground clearance is 420 mm.

It indicates the maximum recommended working section the unit can service—roughly a 24 m length, 15 m width and 12 m height—depending on site layout and hose/boom configuration.

Yes. The machine is designed with a compact layout to operate in tight tunnel and underground spaces, but final suitability depends on specific tunnel cross-section and access constraints.

The machine comes with video outgoing inspection and a machinery test report. On-site safety precautions should include PPE, proper ventilation, trained operators and adherence to local tunneling safety standards.

Recommended routine maintenance includes daily visual checks, lubrication of moving parts, cleaning of hoses/nozzles after use, regular engine and hydraulic inspections, and scheduled servicing per the supplier's maintenance manual.

Training and technical support are typically available from the manufacturer/supplier. Contact Blurbly or your sales representative to arrange operator training and commissioning support.

Yes. Common options include different nozzle and hose configurations, bolting attachments, remote controls or site-specific adaptations. Contact Blurbly for available customization options.

The motor and key pump components are core parts. Spare parts are normally available through the manufacturer or authorized dealers—contact Blurbly to order genuine spares and consumables.

A machinery test report and video outgoing inspection are provided. For specific certifications (CE, ISO, etc.) or custom test documentation, request details from the supplier prior to purchase.

Because of its weight (14,400 kg) and dimensions, transport requires heavy-haul equipment and appropriate permits. Site installation requires a prepared level area, lifting equipment for unloading, and qualified personnel for assembly, electrical/diesel connections and commissioning.
