Major Overhaul, Remanufacturing and Equipment Upgrade Services

Revitalize old equipment and extend the value of the equipment continuously

We have a professional technical team consisting of 30 senior electrical, hydraulic and mechanical engineers, with profound capabilities in equipment system analysis, fault diagnosis, underlying technology research and development, and complex fault repair.

Relying on a standardized and professional equipment overhaul and remanufacturing system, we have established a complete remanufacturing process covering equipment inspection, disassembly, failure analysis, component repair and replacement, system debugging, performance testing and delivery acceptance. We can complete over 30 large-scale mining equipment overhaul and remanufacturing projects with high quality throughout the year.

Through professional remanufacturing technology, we not only help customers restore the performance of the equipment, but also through key component upgrades and system optimization, extend the service life of the equipment, reduce the cost of the equipment's entire life cycle, and maximize the residual value of the existing equipment.

Remanufacturing business scope

We provide professional remanufacturing services covering the entire life cycle of equipment, supporting mainstream underground mining equipment brands:

Zhonghong Full Series Equipment

Zhonghong Original Factory-level Deep Remanufacturing

Based on the equipment's operating years, working hours and actual working conditions, we conduct systematic evaluations and deep remanufacturing of the entire machine and core systems to restore the equipment's good operating performance and reliability, and meet the continuous production requirements.

Epiroc & Sandvik

Professionalized Complete Machine Reproduction

For the entire range of underground loaders and mining trucks from Epiroc (Anbatt) and **Sandvik (Sandvik)**, we offer professional overhaul, reproduction, and performance restoration services.

By conducting comprehensive inspections and repairs on the power system, hydraulic system, transmission system, electrical system, braking system, structural components, and key working devices, we help customers extend the service life of their equipment, reduce the cost of purchasing new equipment and operating it.

Customized Modifications and Intelligent Upgrades

We not only "repair old equipment", but also through technical transformation, give the equipment new capabilities.

According to the safety, efficiency, automation, and intelligence requirements of different mines, we provide flexible customized modifications and upgrade solutions:

Remote Intelligent Control

Install or upgrade remote control systems to achieve human-machine separation operations, reduce the risk of personnel entering dangerous areas, and enhance the safety of operations in complex and high-risk conditions.

Safety Upgrade

Based on the requirements of the mine site, upgrade the equipment safety system, including functions such as automatic release of the braking trailer and automatic fire extinguishing system, further enhancing the active safety and emergency response capabilities of the equipment.

Intelligent Maintenance

Install an automatic lubrication system to achieve automatic and quantitative lubrication of key lubrication points, reduce the workload of manual maintenance, improve lubrication quality, and help extend the service life of pinions, bearings, and other key components.

From "Repairing Equipment" to "Reproducing Equipment"

Traditional maintenance addresses "what went wrong with the equipment".

Reproduction addresses: How to make an old piece of equipment regain the ability to continuously create value.

Through professional inspection, system repair, key component reproduction, and intelligent upgrades, we help customers:

Extend equipment lifespan | Reduce capital investment | Reduce downtime | Improve equipment reliability | Release the value of existing assets.
