30吨道路施工挖掘机 | 重型履带式挖掘机出售

Product Summary

The 30-ton Road Construction Excavator is a heavy-duty crawler excavator specifically calibrated for high-volume earthmoving, road base preparation, and asphalt milling support. With an operating weight of 30,200 kg and a bucket breakout force of 17,500 kgf, it maintains high cycle efficiency even in compacted or rocky terrain. Its modular cooling package ensures stable hydraulic oil temperatures during extended highway construction shifts.

Why Choose This Machinery

Compared to standard 22-25 ton units, this excavator delivers 22% higher lifting capacity over the side and a 15% improvement in fuel efficiency via its electronically controlled variable displacement pump. The reinforced X-frame undercarriage reduces track link fatigue by 30% on demolition and haul road work. For B2B procurement, we offer global RoRo or 40' HC container loading options, a 1-year global warranty with parts depots in Dubai, Houston, and Singapore, and a complimentary wear parts kit (track shoes, bucket teeth, filters).

Powertrain & Structural Overview

Power comes from a Cummins QSB7 (Stage IIIA/Tier 3 equivalent) or optional Isuzu 6BG1 diesel engine, rated at 250 HP. The hydraulic system features a triple-pump flow summing configuration with independent swing priority, delivering 280 L/min main pump flow. The cab integrates a 7-inch LCD monitor with rear and right-side cameras, automatic climate control, and ISO pattern controls. Standard heavy-duty guarding includes a full-length belly pan and reinforced track guards for quarry and roadside debris hazards.

Technical Specifications

Below is the primary data for the road construction excavator. Actual performance may vary depending on altitude, attachment weight, and material density. All values comply with ISO 9249 and SAE J1349 standards.

Heavy-Duty Application Scenarios

Earthmoving & Subgrade Preparation

Efficiently cuts and loads fill material for road embankments. The 1.5 m³ heavy-duty bucket with flame-hardened adapters reduces cycle times when loading rigid dump trucks or articulated haulers in wet clay or laterite conditions.

Quarrying & Base Course Excavation

Equipped with a optional demolition-style guarding and a 1.3 m³ rock bucket, this unit extracts and sizes crushed stone for road base layers. The automatic swing brake prevents drift on slopes up to 15 degrees.

Municipal Road Rehabilitation

Paired with a hydraulic quick coupler and tilt rotator, the excavator handles curb removal, trench digging for drainage, and precision bedding placement for utilities. The ECO mode reduces fuel consumption by 18% during light-duty municipal projects.

Equipment Q&A

Q1: What is the lead time for shipping this road construction excavator to Africa or Latin America?

Standard FOB delivery from Shanghai or Tianjin port is 15-20 days after deposit confirmation. For RORO vessels, lead time to Mombasa, Durban, or Santos is 35-45 days; containerized split (cab + counterweight + tracks) adds 7 days for crating but reduces risk of port damage. We provide daily tracking via our logistics portal.

Q2: Does the 1-year global warranty cover wear parts like bucket teeth and track pads?

The warranty covers structural components (boom, arm, frame, swing ring) and major systems (engine, main pumps, motors, final drives) for 12 months or 2,000 hours. Wear parts are excluded but we include a free starter kit (one set of bucket teeth, two track pads, two hydraulic filters, and air filters) with every export order. Extended service contracts are available for fleets of 5+ units.

Q3: What emission standards are available for markets like Nigeria, Indonesia, or Brazil?

We offer three configurations: (1) Stage IIIA/Tier 3 equivalent (Cummins QSB7) for most global markets, (2) Stage V/EU V with DPF+SCR for EU and UK, and (3) Non-road China IV for Chinese domestic and closely regulated Asia markets. We provide stamped COCs for customs clearance.

Q4: How does the fuel efficiency compare to used Japanese or Korean excavators?

At 70% load factor, our unit consumes 16-18 L/hr versus 22-25 L/hr for typical 2015-2018 models of similar operating weight. Combined with the 450-liter fuel tank, this provides 25-28 hours of continuous operation, reducing refueling stops by one full cycle per shift in remote road projects.

Q5: What attachments are pre-tested for this chassis, and can you provide a combined procurement quotation?

We have certified mounting brackets and flow configurations for hydraulic hammers (up to 2,500 ft-lb), rotating grapples, shears, and 1.8 m ditching buckets. Yes, we supply an all-inclusive quote with attachments, spare parts kits, and site commissioning tools. Volume discounts apply for orders of 6+ units.
