The used CAT 307E2 crawler excavator is a compact earthmoving machine engineered to deliver consistent hydraulic power across urban construction, utility trenching, and agricultural infrastructure projects. Powered by a high-efficiency Cat C2.6 DI Turbo water-cooled engine, this 7-ton excavator provides a rated power output of 41.5 kW, combining high engine torque with fuel-efficient operation during demanding digging cycles. With a total operating weight of 6,900 kg and a standard 0.33 m³ bucket capacity, the machine maintains low ground bearing pressure while supporting maximum bucket breakout force up to 50.6 kN. Every pre-owned Caterpillar 307E2 unit undergoes full technical evaluation—including hydraulic pressure testing, engine load verification, and undercarriage wear inspection—to ensure dependable operation for international commercial machinery buyers.

Heavy-Duty Engineering & Commercial Advantages

Fuel-Efficient Turbocharging & Reliable Power Output: Driven by a 2.6L 4-cylinder Cat C2.6 DI Turbo direct-injection engine, generating 41.5 kW rated power to maintain job-site productivity while optimizing daily fuel consumption.
Robust Hydraulic Digging Force & Bucket Efficiency: Delivers 50.6 kN bucket digging force and 37.1 kN stick digging force paired with a 0.33 m³ standard heavy-duty bucket for fast cycle times in compacted earth and aggregate.
Compact Digging Envelope & Extended Reach: Features a 3,700 mm boom and 1,665 mm stick arm, supporting a maximum excavation depth of 4,070 mm and a maximum digging radius of 6,300 mm within restricted work zones.
Durable Undercarriage & Gradeability Traction: Built with heavy-duty steel crawler tracks, a 135 L fuel tank, and a 35°/70° gradeability rating to ensure stable traction across sloped, muddy, or unpaved terrain.
Low-Noise Enclosed Operator Cabin: Includes a weather-sealed cab with air conditioning, ergonomic pilot controls, and high-visibility glass panels to improve operator comfort and reduce fatigue during extended work shifts.

Job-Site Application Scenarios

Municipal Pipe Laying & Urban Trenching

Featuring an overall width of 2,300 mm and a maximum vertical excavation depth of 3,630 mm, the CAT 307E2 operates efficiently within narrow city streets, dig trenches for water lines, gas mains, and electrical conduits without obstructing adjacent road traffic.

Landscaping, Grading & Agricultural Earthworks

Equipped with a 0.33 m³ bucket and a 10.8 rpm rotation speed, this 7-ton machine handles ditch cleaning, pond excavation, land clearing, and soil leveling across agricultural properties and commercial land development sites.

Light Demolition & Site Preparation

With a maximum unloading height of 5,190 mm and high hydraulic flow compatibility, the unit effectively loads dump trucks, breaks up concrete slabs, and clears debris during building renovation or residential foundation works.

Attachment Retrofitting, Quality Control & Logistics

Custom auxiliary hydraulic piping lines can be retrofitted prior to dispatch to operate hydraulic breakers, quick hitches, augers, or hydraulic grapples according to project needs. Every excavator undergoes a multi-point inspection process, covering hydraulic pump pressure calibration, valve block testing, track tension adjustment, engine fluid flush, and structural stress checks. Detailed operational inspection videos and machinery condition reports are provided before packing. Machines are secured with anti-corrosion protection and shipped internationally via Flat Rack, RO-RO, or 40ft High Cube container systems.

Frequently Asked Questions

How is the condition of the hydraulic pump and main valve verified before shipment?

Our engineering team tests the main Caterpillar hydraulic pump and distribution valve under operational pressure. We measure hydraulic cycle times, test for pressure drops, and check all hydraulic hose lines to ensure leak-free performance.

Can extra auxiliary hydraulic pipelines be installed for hydraulic breakers?

Yes, custom dual-way auxiliary hydraulic pipelines can be retrofitted onto the boom and stick arm to power hydraulic hammers, earth drills, or demolition shears.

What documentation is provided to support international customs clearance?

We supply full commercial documentation including Commercial Invoice, Packing List, Bill of Lading, Certificate of Origin, and complete pre-shipment mechanical test reports.

What is the standard processing and dispatch timeline for export orders?

Routine pre-delivery servicing, hydraulic testing, and attachment retrofitting require 5 to 7 business days. International maritime freight delivery times vary from 15 to 35 days depending on the destination port.
