The 80 Ton Large Hydraulic Excavator is designed with exceptional construction quality, high efficiency, and energy-saving capabilities. It features a customized torque curve, coupled with the largest displacement in the main pump industry, and a combined engine-hydraulic system optimization. This ensures strong performance even under heavy loads and low speeds, providing consistent and reliable power.

The super-strong of hydraulic excavator  structure is built for durability and reliability, incorporating a four-wheel belt, mining working device, and a large-capacity wear-resistant bucket that can handle the toughest tasks with ease.

Technologically advanced, the 80 ton large hydraulic excavator excavator is equipped with a 10.1-inch human-computer interactive intelligent display. This display adapts to working conditions and allows for self-customized operation, ensuring efficiency and ease of use in various environments.

For operator comfort and safety, the excavator includes a standard air suspension seat, a spacious cabin, and a low-vibration, low-noise environment that ensures a comfortable and secure driving experience.

Maintenance is also made easy with a three-level diesel filter and a standard oil bath-type air filter, which are both simple to maintain, reducing downtime and keeping the machine running at peak performance.

Engine

Model: WP17T

Displacement: 16.72L

Emission Certification: Country 4

Weichai + Linde super gold hydraulic combination

Weichai + Linde super gold combination, high matching degree, programming technology, full electronic hydraulic system, fast response speed, better control.

Strong drive

Weichai WP17T high-power engine, high-adaptability turbocharged engine, low speed, large torque, strong power, power is 40% better than competing products, rapid response. It is very suitable for the operation of high intensity mine.

Low fuel consumption

Optimize the fuel injection mode, greatly optimize the curve, increase the economic fuel consumption zone, lower fuel consumption, and save 15% compared with competitive products.

Cost reduction

No post-processing, no EGR, no urea, no low sulfur fuel, no high grade oil, no downtime regeneration, no downtime regeneration time cost.

Optimize the hinge points of the working device

The key joints are equipped with self-lubricating copper base alloy sleeves, which are wear-resistant and effectively reduce wear. Optimize the hinge point of the working device, ensure the bucket mining track, reduce the mining resistance, and the mining force is 9.7% better than the competing products.

Strong digging power

According to the loading operation, the position of the hinged point of the working device is optimized to ensure the bucket excavation track, reduce the excavation resistance, and improve the working efficiency. The new material bucket tooth, bucket tooth holder, tooth guard, abrasion resistance provides 15%, the bevel main cutter plate is more convenient to cut, the cutting force is increased by 10%, and the work efficiency is improved.

Hydraulic combination

HPR300 large displacement main pump, 7% better than competing products, greater output torque. Linde OCV36E main valve, full electronic control system, spool to achieve independent control, better handling. Linde HMF180 rotary motor with strong starting torque and smooth braking. KYB walking motor, low failure rate, walking traction is 10% better than competing products.

Fully electronically controlled positive flow hydraulic system

Fully electronically controlled positive flow hydraulic system, to achieve the perfect combination of load and flow, greatly improve the response speed. The electric control method realizes the relative rotation priority of the boom, the rotation priority of the bucket rod, the boom priority of the bucket rod, and the combination of the bucket, etc., cancelling the priority logic valve and reducing the pressure loss.
