Product Introduction
This tractor-coupled pipeline slotting and trenching machine is a versatile heavy-duty attachment tailored for cross-industry excavation demands. It operates as a reliable pipe burying trencher for underground water, gas and power pipeline laying, an efficient field ditching machine for farm irrigation and orchard fertilization furrow construction, and a robust engineering slotting machine for municipal weak current cabling and photovoltaic project trenching. Compatible with 50–240HP wheel tractors equipped with creeper ultra-low gears, it features a manganese steel chain paired with tungsten carbide cutting teeth, plus hydraulic lift control and dual spiral soil-discharging design. It can carve neat vertical-wall trenches on sandy soil, loam, red earth and other loose terrain, with adjustable trench depth (20–200cm) and width (12–100cm) to match diverse project specs.
Core Competitive Advantages
1.Outstanding Wear Resistance: National-standard manganese steel chains and alloy gold-head cutters withstand frequent impact from small stones and sticky clay, cutting long-term spare part replacement expenses for bulk buyers.
2.Flexible On-site Adjustment: Digging depth can be tweaked in real time via the tractor's hydraulic system without halting operations, boosting continuous working efficiency up to 240–500 meters per hour.
3.Neat Trench Forming: Twin spiral side-throwing structure spreads excavated soil evenly on both trench sides, preventing backfill and reducing follow-up pipeline laying labor.
4.Wide Compatibility: Standard three-point hitch fits most mainstream tractor brands; single/double chain configurations cover shallow farm jobs and deep engineering slotting respectively.
5.Low Maintenance Threshold: Bolt-fixed cutting teeth allow quick single-tooth replacement with basic hand tools, no specialized workshop required.
Export-Optimized Packaging & Transportation
Each machine is packed in thick fumigation-free export plywood cases reinforced with steel strapping to resist vibration and collision during long-distance sea and land shipping. Fragible hydraulic fittings, spare cutting teeth and connecting pins are individually cushioned and sealed inside the crate. Detailed packing manifests and specification labels are affixed externally to streamline customs clearance. We support LCL and FCL shipments, and can coordinate door-to-door logistics for regional distributors.
Comprehensive After-Sales Service
12-month warranty for core components (gearbox, drive chain, hydraulic motor) under standard operating conditions.
Round-the-clock, multilingual remote technical support, including operation tutorials and video-based troubleshooting guidance for pipeline slotting and trenching machines.
Fast global spare parts dispatch, with commonly worn items deliverable within 7 working days.
Customized structural modification: adjust hitch size, trench dimensions to fit regional tractor models for free design optimization.
Common Faults & Targeted Solutions
Uneven trenching depth
Check hydraulic oil pressure and cylinder blockages; top up qualified hydraulic fluid and clear blocked pipelines to restore stable lifting.
01
Slow chain rotation
Inspect tension degree of the drive chain; tighten loose tension springs and remove tangled soil residues stuck in chain gaps.
02
Soil backfilling into trenches
Clean clogged spiral soil-throwing blades and adjust the blade angle for smoother soil discharge.
03
Abnormal gearbox noise
Replace worn internal gears and replenish high-viscosity gear oil as required by the operation manual.
