The DALI SJD-400 is an electric mobile rock splitter for secondary breaking in underground mines and tunnels. Its 1.23 m width, 85 mm rod, 400-800 bpm published beating frequency and 45 kW motor suit restricted work areas where a compatible electrical supply can be provided.

SJD-400 packages an electric motor, hydrostatic transmission and mobile carrier around a compact splitting tool. It is best evaluated where oversize rock occurs within reach of a suitable mine power supply and where its 1.23 m body width fits the complete travel and working envelope.
Voltage, cable arrangement, connection method and protection equipment are not published. These items must be engineered before the electric version is selected over the diesel SJ-400.
The published 6.82 x 1.23 x 2.00 m dimensions prioritize access. Check bends, floor condition, articulation sweep, tool position and operator exclusion space rather than using body width alone.
The 85 mm rod and 400-800 bpm figure describe tool size and action frequency, not proven splitting output. Rock strength, jointing, boulder size and predrilled-hole geometry still determine suitability.
The page lists a Y225M-4 motor rated at 45 kW and 1,480 rpm. Confirm supply voltage, frequency, starting method, cable length and mine electrical protection before quotation.
Hydrostatic transmission, rigid planetary axles, a front NO-SPIN differential and Posi-stop braking are listed for positioning underground.

SJD-400 uses a 45 kW electric motor; SJ-400 lists a 47.5 kW Deutz diesel engine. Both pages publish a 1.23 m width and 85 mm rod, but their power-infrastructure requirements differ.
The current page does not state voltage or frequency. Send the site electrical standard and connection distance for confirmation.
No onboard drilling system is described. Confirm the predrilling equipment and required hole geometry as part of the workflow.
Splitting force and tool stroke are not published. Request verified values together with rock and hole compatibility guidance.
