Product Summary
The {keyword} is a purpose-built 22.5-ton class earthmoving solution for global contractors and mining operators. Powered by a 150HP (112kW) turbocharged diesel engine and a load-sensing hydraulic system, it delivers a breakout force of 165 kN and a maximum digging depth of 6.8 meters. Designed to meet Tier 3 / Stage V emission equivalents, this machine balances raw power with supply chain efficiency, including full container or RORO shipping from our global logistics hubs.
Why Choose This Machinery
Unlike used or low-cost alternatives, our building excavator provides verified OEM-grade durability with measurable ROI advantages. The reinforced X-frame undercarriage and ISO 9001-certified main control valve reduce fuel consumption by up to 18% compared to previous models. Key competitive edges include:
• Global Shipping Ready: Collapsible boom and standard 20ft/40ft container dimensions reduce logistics costs.
• Full Spare Parts Backing: Undercarriage (track chains, rollers) and engine wearing parts available for 5+ years.
• High Heat Resistance: Hydraulic oil cooler and radiator package rated for ambient temperatures up to 45°C (113°F).
• 1-Year / 2,000-Hour Global Warranty: Covers powertrain and main hydraulic components with on-site parts replacement.
Powertrain & Structural Overview
The heart of the {keyword} is its Cummins QSF3.8 diesel engine, offering low-end torque for heavy digging cycles and a common-rail fuel system for Tier 4 Final compliance options. The closed-center, load-sensing hydraulic system (250 lpm main pump) independently supplies oil to the boom, arm, bucket, and travel circuits, ensuring precise multi-function control without power fade. The heavy-duty box-section boom and one-piece cast steel arm bracket are reinforced with high-tensile wear plates. Inside the ROPS/FOPS-certified cab, operators benefit from a 7-inch LCD monitor, automatic climate control, and a shock-absorbing seat to reduce fatigue during 12-hour shifts.

Heavy-Duty Application Scenarios
Earthmoving & Site Preparation
Ideal for mass excavation, sloping, and backfilling on residential or commercial construction sites. The high boom lift capacity (7.2 tons) allows for loading dump trucks on uneven terrain.
Quarrying & Aggregates
The reinforced track frame and optional heavy-duty rock bucket (0.9m³ with wear caps) enable loading of shot rock, limestone, and gravel at quarry faces. A standard rotary screen protects the cooling package from dust.
Municipal Utility Installation
With optional pipe grapples and tilt rotator compatibility, the excavator handles trenching for water, gas, and telecom lines in urban environments. Reduced tail swing (radius of 2.1m) improves maneuverability near traffic and existing structures.
Equipment Q&A
Q1: What is the exact shipping lead time for RORO or container shipment?
A1: For standard 22-ton building excavators, we maintain stock at our export yards in Shanghai, Rotterdam, and Dubai. RORO vessel lead time is 14 days for documentation and 25-40 days for ocean transit to major ports (e.g., Houston, Lagos, Santos). Container loading (1x 40HQ per unit) adds 3 days for disassembly.
Q2: What wearing parts are included with the initial purchase?
A2: Each unit includes one complementary wearing parts package: two sets of bucket teeth & pins, one set of track pads, two primary fuel filters, and three hydraulic return filters. We also provide a full parts catalog with OEM cross-references.
Q3: Does the machine meet my region's emission standards (EU, US, Australia)?
A3: The base configuration is EU Stage IIIA / EPA Tier 3 equivalent. For stricter regions (EU Stage V or Tier 4 Final), we can install a DOC+DPF after-treatment system with a 2% price uplift. Please specify your emission class when ordering.
Q4: How is operator training handled for overseas buyers?
A4: We provide a full-color operator manual, a 3-hour interactive video tutorial (USB drive), and remote WhatsApp/WeChat support. For fleet orders (5+ units), we can send a factory technician for on-site training (travel & accommodation costs extra).
Q5: What is the warranty claim process for hydraulic or engine failure?
A5: Our 1-Year Global Warranty covers parts and labor for major components (engine, main pump, control valve, swing motor). For claims, you submit a video diagnosis and hydraulic oil sample report. Approved parts are air-shipped DDP (Delivery Duty Paid) within 7 calendar days. Local service reimbursement is capped at $80/hour.
