Used Compact Excavator Machinery Kubota U55 | Longmai

Sourcing a certified used Kubota U55 compact excavator offers contractor fleets, municipal utility works, and earthmoving enterprises an agile machine for restricted job sites. Operating at a total weight of 12,335 lbs, this tight-tail swing excavator delivers steady digging forces while remaining easy to move between urban job locations. Overseas machinery buyers benefit from factory-grade performance and reduced equipment procurement overhead. Our equipment holding yard subjects every pre-owned unit to rigorous hydraulic pressure testing, structural checks, and complete service preparation before export shipping.

Advanced Hydraulic Engineering and Structural Capabilities

Every pre-owned compact excavator in our inventory undergoes detailed inspection by heavy machinery specialists to ensure compliance with strict working standards.

Kubota V2607 Direct-Injection Diesel Powertrain

This 5.5-ton compact excavator relies on the original Kubota V2607 liquid-cooled diesel engine, generating a net output of 45.2 hp. Engineered for extended service life under continuous earthmoving duty, this power unit balances high working torque with minimized hourly fuel consumption. The clean engine installation ensures easy service access for routine oil, air, and fuel filter replacements.

High-Output Hydraulic Pump and Digging Force

The main hydraulic system delivers a combined total flow of 39.4 gpm across implement and swing circuits, maintaining a maximum relief valve pressure of 3,980 psi. Equipped with a standard 5' 2" arm, the unit produces an impressive 11,177 lbs of bucket digging force and 6,261 lbs of arm breakout force. This hydraulic balance ensures rapid cycle times when excavating dense clay, trenching, or handling aggregate materials.

Tight Space Maneuverability and Stability

Featuring a tail overhang over side of just 2.6 inches, the compact frame allows operators to swing freely near building walls, highway barriers, and tight fencing without risking counterweight impacts. The 15.7-inch track shoes provide a stable 6' 6" ground contact length, supporting a maximum drawbar pull of 14,480 lbs and a maximum travel speed of 3.1 mph across uneven terrain.

Verified Factory Technical Specifications

The operational values listed below represent exact engineering metrics verified during physical machine inspection prior to yard inventory registration.

Primary Industrial Application Scenarios

Urban Utility Trenching and Pipe Installation

With a maximum dig depth of 11' 10" and a ground reach of 19' 6", this compact excavator routinely performs water line trenching, electrical conduit laying, and sewer repairs in tight residential corridors where zero-tail design is essential.

Site Preparation and Foundation Footings

The 13' 2" dump height allows operators to easily load high-sided tandem dump trucks or stockpile soil. The 55° right and 70° left boom swing angles enable precise footing excavations along existing structures without constantly re-positioning the tracks.

Landscaping and Civil Groundwork

Supported by 5,290 lbs of over-end lifting capacity at a 10' radius, the machine handles heavy concrete culverts, retaining wall blocks, and land clearing debris efficiently.

Customization, Maintenance, and Logistics Support

We provide technical preparation and export logistics tailored to international equipment buyers.

• Hydraulic Pressure Benchmarking: Every unit undergoes hydraulic valve calibration and cylinder seal checks to confirm factory pressure compliance before export.

• Filter and Fluid Renewal: Engine oil, hydraulic filters, fuel lines, and cooling systems are fully serviced using original factory-grade replacement components.

• Auxiliary Circuit Configuration: Optional quick-coupler setups, auxiliary piping for hydraulic breakers, and trenching buckets ranging from 12" to 48" can be equipped on request.

• Global Shipping Coordination: Equipment is secured using Flat Rack containerization or specialized RoRo vessel shipping, complete with commercial invoices and export documentation.

Frequently Asked Questions (FAQ)

How is the hydraulic pump flow verified before export shipment?

Our service technicians connect inline flow meters and pressure gauges to the main hydraulic circuits. We test implemented flow rates up to 39.4 gpm at the 3,980 psi relief threshold under simulated load conditions.

Can this excavator be fitted with both rubber tracks and steel shoes?

Yes, depending on site surface requirements, we can supply units with 15.7-inch steel track chains or heavy-duty rubber tracks for urban asphalt operations.

What documentation is provided for international port customs?

We supply full commercial shipping documents, including certified bills of lading, equipment packing lists, commercial invoices, and origin technical inspection reports.

What are the exact transport dimensions for flatbed trailer shipping?

The machine measures 18' 1" in transport length, 6' 5" in transport width, and 8' 4" in transport height, with an operating weight of 12,335 lbs.

What payment terms apply to equipment orders?

Transactions are completed via secure Bank Telegraphic Transfer (T/T). Orders are processed upon deposit confirmation, with final balance settlement following document issuance.
