45吨重型采石场挖掘机 | 高效采矿铲

Product Summary

This 45-ton Quarry Excavator represents a breakthrough in high-volume material handling. Designed specifically for primary excavation in granite, basalt, and limestone quarries, it combines a 310 HP (231 kW) turbocharged engine with a robust 2.8 m³ heavy-duty bucket. The reinforced boom and arm deliver 28% higher digging force than standard MC models, while the advanced negative flow control hydraulic system reduces fuel burn by up to 15% per ton of material moved.

Why Choose This Machinery

In the high-stakes environment of quarry operations, downtime is the single greatest cost driver. This machine outcompetes standard excavators through three core advantages: Durability, Efficiency, and Global Supportability. The undercarriage features lifetime-lubricated track rollers and double heat-treated manganese steel links, extending wear life by 2,000+ hours in abrasive rock conditions. Compared to regional competitors, our closed-center hydraulic system provides simultaneous boom and bucket functions without power loss, increasing cycle speeds by 18%. Furthermore, as a top-tier exporter, we maintain a dedicated global spare parts warehouse, ensuring 95% of wear parts (teeth, pins, filters) ship within 24 hours.

Powertrain & Structural Overview

Power comes from a Isuzu 6WG1 Tier 3 / Stage V compatible engine, providing reliable 310 HP with a maintenance-free SCR system. The cooling package is upgraded with a dual-core radiator and swing-out fan guard, allowing 50°C ambient temperature operation. The hydraulic system utilizes Kawasaki main pumps and a KYB control valve, delivering 2 x 280 l/min flow at 34.3 MPa. The cab features a FOPS/ROPS certified structure, a 7-inch LCD monitor with real-time payload metering (optional), and automatic climate control.

Technical Specifications

Below is the primary data for the heavy-duty quarry excavator. All measurements comply with ISO 7451 standards. Specific configurations are adjustable based on quarry material density and transportation needs.

Heavy-Duty Application Scenarios

Earthmoving

Efficient high-bank cutting and slope leveling for large-scale site preparation and mine haul road maintenance.

Quarrying

Primary rock excavation, shot rock mucking, and direct feeding of fixed jaw crushers and mobile crushing trains in aggregates or limestone quarries.

Municipal Construction

Heavy excavation for dam foundations, tunnel portal excavation, and large-diameter pipeline trenching in challenging terrain.

Equipment Q&A

Q1: What is the typical shipping lead time and what transport modes are available?

Standard lead time is 25-35 days after deposit confirmation. We support global Ro/Ro shipping (most cost-effective for rolling machinery) or containerized flat-rack shipping for partial knockdown (PKD) units. Direct FOB delivery from Shanghai or Tianjin port.

Q2: Do you offer an extended wearing parts package for quarry conditions?

Yes. We provide a 'Rock Package' including: 20x bucket teeth, 10x side cutters, 4x track pads, 2x boom bushings, and 3x full filter kits. This package is priced at $3,850 and reduces procurement lead time by 60%.

Q3: What emission standards are available for different global markets?

We supply engines compliant with EU Stage V, US EPA Tier 3, and China National IV standards. Non-road mobile machinery (NRMM) certification documents are provided for customs clearance in the EU, Australia, and Southeast Asia.

Q4: Is operational training provided for the high-pressure hydraulic system?

Standard delivery includes 2 days of on-site commissioning and operator orientation. We also offer remote video support and a digital maintenance manual. Optional: $1,200 for a certified trainer to provide 5 days of advanced quarry cycle training.

Q5: What is the standard warranty and after-sales support structure?

The standard is a 1-Year Global Warranty covering major powertrain and hydraulic components (engine, pump, motors, main valve). We have a regional parts depot in Dubai, Houston, and Rotterdam. Extended warranty (3 years / 6,000 hours) is available for an additional 6% of machine FOB price.
