Cut Stone Blocks Into Slabs, Kerbs & Architectural Components
Marble block trimming removes irregular edges and rough surfaces from quarry blocks. The bridge cutting machine's precision blade control trims marble quarry blocks to remove damaged edges and create clean, straight surfaces. The anti-wear design handles marble's softer characteristics while maintaining cutting accuracy. This trimming process prepares marble blocks for downstream cutting and shaping operations.
Limestone kerb stones require consistent dimensions for road construction applications. The cutting machine processes limestone quarry blocks into uniform kerb stone shapes using powerful main motors and stable worktable positioning. The adjustable blade travel accommodates different kerb stone size requirements. This quarry processing delivers road-grade limestone kerb stones meeting basic municipal construction needs.
Granite tombstone blanks are cut from large quarry blocks for memorial stone production. The bridge cutting machine cuts granite quarry blocks into tombstone-sized blanks using hydraulic slider technology. The stable cutting platform ensures straight cuts while the robust construction handles granite's demanding cutting requirements. This quarry block processing provides memorial stone fabricators with properly sized granite blanks for tombstone manufacturing.
Sandstone slab cutting transforms quarry blocks into manageable slab sizes for construction use. The cutting machine processes sandstone quarry blocks into standard slab dimensions using adjustable blade parameters. The hydraulic system provides controlled cutting pressure suitable for sandstone's varying density characteristics. This slab cutting operation prepares sandstone blocks for architectural and construction applications requiring uniform thickness.
The QSDP series pairs a hydraulic slider system with seven blade sizes from 1600 to 3200 mm, cutting raw quarry blocks into slabs, kerb stones and tombstone blanks with an anti-deformation bridge frame.
Seven models (1600–3200 mm blade) cover workshop trimming to quarry-scale cutting — select by block width and daily volume.
Motor power scales with blade class, delivering cutting force for granite through limestone.
The hydraulic slider lifts fast with anti-wear design and easy maintenance, shortening non-cutting time between passes.
The trolley table moves blocks and slabs in and out of the cutting zone in two table sizes.
Applicable materials: Granite, marble, sandstone, travertine and limestone.
Typical products: Stone slabs, kerb stones, tombstone blanks and dimension stone from raw quarry blocks.
Actual cutting speed varies with stone hardness, blade specification and on-site conditions.
Select the QSDP model from three variables: maximum block size, required cutting depth and daily block volume. Blade diameter rises from 1600 to 3200 mm, while trolley size (1700 × 1700 / 2000 × 2000 mm) and lifting stroke scale with larger quarry programs; feeding travel extends to 5200 mm for long blocks.

Six core systems for quarry-block cutting duty. The numbered points on the machine diagram correspond to the systems below.
A block program follows four steps: roll the block onto the trolley table, align and clamp, run the hydraulic cutting cycle, then roll out the slabs and reload — continuous programs stack cuts with minimal crane involvement.
The hydraulic slider combines fast lifting, controlled cutting feed and an anti-wear structure, shortening non-cutting movement between passes while keeping maintenance straightforward.
A robust bridge structure with an anti-deformation framework keeps the blade on line through full-depth cuts, protecting slab thickness consistency on long blocks.
Seven blade classes from 1600 to 3200 mm let factories size the machine around actual block dimensions and cutting depth instead of forcing every job onto an oversized platform.
The trolley brings the block into and out of the cutting zone, so the crane is used for loading rather than repeated repositioning during every pass.
Hydraulics and wear parts are positioned for direct access, keeping routine maintenance short in the dust-heavy block-yard environment.
Blade speed and motor class are matched to blade diameter — from about 408 rpm on a Φ2200 blade to 327/384 rpm on Φ2500 and 287 rpm on Φ2800 — keeping the cutting edge in the correct operating range across all seven sizes instead of forcing one spindle condition onto every blade.

Common Questions About Bridge Single-Blade Stone Block Cutting Machine
A bridge stone block cutting machine is specialized quarry equipment that uses a single diamond blade mounted on a hydraulic slider to cut large stone blocks into slabs and smaller blocks. The "bridge" design provides overhead stability for processing heavy quarry blocks. This equipment is essential for initial quarry block processing and stone preparation in quarries and stone fabrication facilities.
DINOSAW bridge block cutting machines accommodate quarry blocks up to 2000x2000m on the worktable (length and width), with blade diameters from 1600-3200mm providing maximum cutting height of 1480mm (calculated as 3200mm blade diameter minus 200mm fixing parts and 20mm safety clearance). The machines handle blocks weighing several tons, making them ideal for processing large quarry blocks into manageable sizes for further processing or direct use in construction projects.
Regular maintenance includes daily hydraulic fluid level checks, weekly blade inspection for wear, monthly motor lubrication, and cleaning of stone debris after each operation. The anti-wear design minimizes component replacement frequency. Most routine maintenance tasks can be performed by operators with basic training, reducing downtime and service costs.
Safety features include emergency stop controls, blade guards, hydraulic pressure relief valves, and stable bridge frame design. The trolley system ensures secure block positioning during cutting operations. All electrical components meet industrial safety standards for quarry and fabrication environments.
Yes, the bridge block cutting machine handles various stone types including granite, marble, sandstone, limestone, and travertine. Blade selection and cutting parameters can be adjusted for different materials. The robust construction accommodates varying stone hardness levels without compromising cutting quality or machine stability.
Match blade diameter to your block width and cutting depth program, then check table size: the 1600–1800 mm models with 1700 × 1700 mm trolley tables suit workshop trimming and kerb stone programs; the 2200–2600 mm class handles full quarry blocks on 2000 × 2000 mm tables; the 2800–3200 mm class serves large-block dimension stone with 1500–1600 mm lifting strokes. Feeding travel also matters — long blocks need the 4800–5200 mm feeding class. DINOSAW can verify the match from your block dimensions before configuration.
Choose by production style. Single-blade cutting (QSDP) wins when block sizes vary, products change between slabs, kerbs and tombstone blanks, or the program is trimming-oriented — one large blade flexes across jobs with simple setups. Multi-blade cutting (LMDQ) wins when slab thickness is standardized and volume is the target — a blade set slices several slabs per pass at up to 120 m²/h. Many factories run both: single-blade for flexible trimming and odd sizes, multi-blade for the volume program.
