Product Introduction
The concrete trenching machine is a heavy-duty tractor-mounted attachment engineered to cut clean narrow trenches on concrete, cement pavement, compacted hard soil and gravel ground. Unlike lightweight small trenching machine models designed for soft farmland only, this heavy unit delivers powerful cutting force through a large serrated circular cutter disc, also named disc ditching machine for its core working structure. As professional pipeline trenching equipment, it meets strict depth and width standards for municipal water, gas, fiber optic and power cable burial, while also serving as a practical agricultural ditching implement for orchard drainage and deep fertilization furrows. Classified as a reliable deep digging ditching machine, it supports customizable digging depth from 20cm up to 100cm, matched with tractors over 100 horsepower via rear three-point suspension and heavy-duty Steyr axle gearbox for stable long-hour high-load operation.
Wide Application Fields
Municipal Road Construction: Curb slotting, concrete road pipeline trenching, old highway reconstruction and roadside drainage channel excavation, the core scenario for this pipeline trenching equipment.
Agricultural Planting & Orchard Management: Deep drainage ditches, organic fertilizer furrows and farm irrigation channels, the main usage of this agricultural ditching implement.
Landscape & Greening Projects: Green belt irrigation slots, seedling planting troughs and park drainage works.
Rural Infrastructure: Rural photovoltaic cable laying, residential community buried pipeline construction, taking advantage of its identity as a deep digging ditching machine for deep underground pipeline standards.
Civil Engineering: Guardrail foundation grooving, border stone slotting and small-scale road maintenance on rigid concrete surfaces where small trenching machine cannot penetrate.
Advanced Manufacturing & Process Technology
1.High-strength Raw Material Selection: The cutter disc and main frame adopt thickened Q345 manganese steel, and each digging tooth is forged from wear-resistant alloy steel to extend service life on hard concrete.
2.Precision Laser Cutting & CNC Forging: All structural parts are laser blanked to eliminate dimensional deviation; cutter teeth are hot forged to enhance impact resistance against concrete fragments.
3.Shot Blasting Anti-Corrosion Treatment: Full surface shot blasting removes rust and oxide layers, followed by two layers of anti-rust primer and finish paint to resist damp construction environments.
4.Seamless Heavy Load Welding: All load-bearing joints are fully penetrated welded by professional welders to avoid frame deformation during deep concrete cutting.
5.Pre-Delivery Full Load Testing: Every finished disc ditching machine undergoes continuous 2-hour load operation testing to inspect gearbox smoothness and disc rotation stability before shipment.
Practical Common Fault Solutions
1.Concrete trenching machine cutter disc stalls when cutting concrete Solution: Stop the machine and clean concrete debris stuck between alloy teeth; inspect the drive gearbox for oil shortage and replenish dedicated heavy-load gear lubricant; adjust chain tension to eliminate jamming.
2.Uneven trench depth during continuous operation Solution: Check the tractor suspension hydraulic system for oil leakage; remove dirt blocking the lifting cylinder stroke and calibrate the depth limiting bracket.
3.Gearbox generates loud abnormal knocking noise Solution: Drain aged contaminated gear oil and refill high-viscosity anti-wear lubricant; disassemble to check for worn gears or damaged bearings and replace damaged components timely.
4.Cutter teeth wear down quickly on harsh concrete ground Solution: Adjust tractor forward speed to avoid overloading the disc; order spare alloy digging teeth and replace heavily worn teeth in batches; keep the disc perpendicular to the ground during trenching.
