The DALI KSP-2509C is a self-propelled underground concrete sprayer for mechanized shotcrete support in metal mines and engineering tunnels. It combines a 25 m³/h concrete pump, synchronized accelerator dosing, onboard air compression and a remote-controlled spraying boom. A 2.03 m machine width and articulated four-wheel-drive chassis support access in confined underground headings.

As an underground concrete sprayer, the KSP-2509C combines tramming, concrete pumping and spraying on one articulated carrier. It is intended for mechanized shotcrete application during ground-support work in underground metal mines and civil-engineering tunnels.
The machine uses a diesel engine for tramming and a cable-connected 380 V/50 Hz electrical system for spraying operations. Its onboard concrete pump, accelerator-dosing pump, air compressor and cleaning system reduce the number of separate units that must be coordinated at the heading.
The hydraulic double-piston pump has a maximum published output of 25 m³/h and pumping pressure of 7.5 MPa. A DN65 delivery line and automatic lubrication are listed. Actual spraying output will depend on the concrete mix, aggregate, hose layout, accelerator rate and application conditions.
The multi-degree-of-freedom hydraulic boom is operated by wireless remote control. Published coverage reaches up to 9 m high, 15 m wide and 8 m forward, while 2.6 m boom travel and multiple boom and nozzle rotations help position the spray across the tunnel profile.
A hydraulic screw pump meters accelerator from 50 to 1,000 L/h. The PLC control system is described as adjusting accelerator output in proportion to concrete flow, helping the operator match dosing to the selected shotcrete mix and pump rate.
The electric screw compressor provides a published air supply of 9.3 m³/min at 8 bar. Integrating the compressor on the carrier simplifies equipment setup, but the required mine power supply and simultaneous electrical load must be checked before deployment.
A hydraulic high-pressure cleaning pump provides up to 35 L/min at 15 MPa through a 15 m water hose. The hopper also includes a hydraulic agitator and electric vibrator to support material flow, cleaning and routine servicing after spraying.
The 2,030 mm-wide carrier uses four-wheel drive and ±40° articulation. Published inner and outer turning radii are 3,830 and 6,700 mm, with 350 mm ground clearance and 25% maximum gradeability for underground access and repositioning.
The specification lists wet-brake axles with service, parking and emergency braking functions, including spring-applied hydraulic-release parking brakes. A closed air-conditioned cab, reversing camera, automatic fire-extinguisher provision and equipment-status display are also listed.
Before ordering, confirm the tunnel width, height, bend radii, gradient, access route and required sprayed area. Compare these values with the machine’s 8.60 × 2.03 × 2.49 m transport envelope and spraying coverage rather than selecting on pump capacity alone.
Provide the approved concrete mix design, maximum aggregate size, slump or flow characteristics, fiber type and dosage, accelerator chemistry and required dosage range. Also state the target layer thickness, surface profile, expected rebound control and required production per shift.
The spraying system requires a compatible 380 V/50 Hz mine supply and uses a 100 m cable reel. Confirm supply capacity, connector, earthing, protection, cable routing and water availability. The published data lists separate 45 kW motors for the working system and air compressor; engineering should confirm the total connected and starting load.
Wireless control allows the operator to position the boom away from the nozzle while maintaining a view of the spraying area. The chassis also lists fail-safe parking brakes, reversing camera, fire protection, CAN-bus diagnostics and an IP65 electrical-system rating.
These features do not by themselves establish compliance with a mine or destination market. Before purchase, confirm operator protective structures, emergency stops, remote-control stop functions, cable protection, high-pressure hose restraints, concrete-line pressure release, fire-suppression specification, guarding, lighting and required certifications.

The listed double-piston concrete pump, accelerator-dosing system and spraying arrangement are consistent with mechanized wet-mix shotcrete. Confirm the approved mix design, aggregate size, fibers and accelerator with DALI before publication or ordering.
The published maximum spraying envelope is 9 m high and 15 m wide, with an 8 m forward spraying distance. Machine access must also accommodate the 2.03 m width, 2.49 m height and turning radii.
The page lists 25 m³/h as pumping ability but does not state whether it is theoretical pump output or guaranteed sprayed output. Actual placement depends on the concrete mix, aggregate, hose arrangement, accelerator setting, rebound and operating conditions.
The hydraulic screw pump has a published 50-1,000 L/h range. The PLC is described as adjusting dosing proportionally with concrete flow. Confirm accelerator compatibility, calibration method and control accuracy for the project.
The spraying system is listed for 380 V/50 Hz and includes a 100 m cable. The data also lists 45 kW working and compressor motors. Ask DALI to confirm total connected load, starting current, connector, cable protection and site transformer requirements.
Send the tunnel profile, access dimensions, gradient, spraying area, concrete mix, maximum aggregate size, fiber and accelerator details, target thickness, required output, electrical supply, water supply, destination country and safety requirements.
