The DALI SJ-500 is a larger diesel mobile rock splitter for secondary breaking in mines and tunnel projects. Compared with SJ-400, it uses a 105 mm rod, 92 kW engine and 1.84 m-wide carrier. It is the capacity-led option when access permits the larger machine and tool package.

SJ-500 is intended for work areas where the larger carrier and 105 mm rod can be accommodated. It supports mobile secondary breaking of oversized rock before loading or crushing, subject to compatible geology and predrilled-hole conditions.
The page does not publish splitting force, tool stroke, rock-strength range, hole specification or cycle time. SJ-500 should therefore be positioned as the larger configuration, not as a proven higher-output machine until those values are verified.
The rod diameter is 20 mm larger than SJ-400. Engineering must still confirm how rod size relates to splitting force, hole diameter, hole depth and the target rock.
The 8.3 x 1.84 x 2.62 m envelope requires more roadway and positioning space than SJ-400. Check articulation sweep, overhead services and working clearance.
The page lists a Deutz BF4M1013C rated at 92 kW, with F6L914 as an option. Confirm current engine, cooling, emissions and exhaust-treatment configuration.
Published components include DANA C270 torque converter and RT20000 gearbox, rigid planetary axles, front NO-SPIN differential and Posi-stop braking.

Choose SJ-500 when the roadway accepts its larger envelope and engineering confirms a need for the 105 mm tool. Choose SJ-400 when minimum access width is the controlling constraint.
Not from the published evidence. Splitting force and tool geometry must be supplied before making that claim.
The current page does not specify hole diameter or depth. Confirm the predrilling plan with DALI before purchase.
Send tunnel drawings, rock type/strength, boulder dimensions, hole plan, ventilation constraints and destination country.
