Product Summary
Engineered for heavy-duty continuous operation, this 22-ton class Diesel Digger combines a Cummins QSB6.7 diesel engine with a high-efficiency load-sensing hydraulic system. The reinforced boom and arm are built for rock digging and deep foundation work. Operating weight 22,000 kg, bucket breakout force 152 kN, and maximum digging depth 6.6 meters. Exported fully assembled via 40ft flat rack containers or RoRo shipping.
Why Choose This Machinery
Compared to legacy 20-ton class diggers, this model reduces fuel consumption by 12-15% through intelligent auto-idle and three power modes. The HD undercarriage features seven bottom rollers per side and sealed track chain, extending service life in abrasive environments by 30%. 1-year global warranty covers powertrain and hydraulics, with genuine spare parts warehousing in Dubai, Singapore, and Houston for 48-hour dispatch. ROI break-even typically achieved within 18-24 months on rental or contract earthmoving projects.
Powertrain & Structural Overview
The Cummins QSB6.7 engine meets Tier 3 / Stage IIIA emission standards (higher-tier available upon request), delivering reliable torque at low RPM. The closed-center hydraulic system with variable-displacement piston pumps ensures simultaneous swing, boom, and bucket operations without flow loss. Cab features ROPS/FOPS certification, adjustable air suspension seat, 7' LCD monitor showing real-time fuel consumption, maintenance intervals, and hydraulic oil temperature. The X-frame chassis with reinforced track frames withstands twisting forces on uneven terrain.

Heavy-Duty Application Scenarios
Earthmoving & Bulk Excavation
Ideal for mass excavation in housing developments, road widening projects, and agricultural land leveling. The 1.1 m³ bucket with bolt-on wear strips achieves 200+ cycles per shift.
Quarrying & Rock Digging
Equipped with a reinforced rock bucket and hydraulic impact hammer circuit, the digger efficiently breaks and loads blasted limestone, granite, and basalt with minimal vibration transmitted to the cab.
Municipal Deep Utility Trenching
Maximum digging depth of 6.6 meters and boom swing offset capability (optional) allow precise trenching for water, sewer, and gas pipelines adjacent to existing infrastructure.
Equipment Q&A
Q1: What is the current shipping lead time for a 22-ton Diesel Digger to a major port like Durban or Hamburg?
A: Lead time from order to vessel departure is 15-25 days, depending on vessel scheduling at the loading port (Shanghai / Tianjin). RoRo shipping typically adds 25-45 days transit to major global ports. We provide daily tracking updates via our logistics portal.
Q2: What standard wearing parts are included with the first purchase?
A: Every unit includes a complimentary wearing parts kit: one set of bucket teeth (5 pcs + holders), two hydraulic return filters, two fuel filters, one air filter element, and a set of track pad bolts. This allows immediate field maintenance for the first 500 operating hours.
Q3: Can this digger be modified to meet EU Stage V or US EPA Tier 4 Final emissions?
A: Yes. We offer a variant equipped with a DOC+DPF aftertreatment system and cooled EGR. The Tier 4 Final version adds approximately US$8,200 to the base price and requires ultra-low sulfur diesel (15 ppm). Please specify your destination country when requesting a quotation.
Q4: Do you provide operator training and diagnostic software?
A: We supply a multilingual operator manual and a laptop diagnostic kit (USB interface) with our proprietary software for reading DTC codes, resetting maintenance timers, and calibrating hydraulic proportional valves. Online video training and 24/7 technical support via WhatsApp are free.
Q5: What is the maximum shipping angle for Ro-Ro, and is undercarriage damage covered?
A: The digger is lashed to withstand a 35-degree roll and 20-degree pitch during Ro-Ro transit. We provide all-risk marine insurance at 1.2% of invoice value, covering any undercarriage or hydraulic component damage caused by vessel motion or improper lashing. The 1-year warranty becomes effective upon arrival at the destination port.
