Client Background

The client is a mid-sized nickel mining company on Sulawesi Island, Indonesia. Sulawesi is one of the world's key laterite nickel production regions. In recent years, growing demand for new energy vehicle battery materials has driven continuous expansion of local nickel mining. The mine uses underground mining methods. The site is located in a tropical rainforest with year-round high temperatures and heavy rainfall. Underground humidity is extremely high, tunnels are narrow, and the floor is soft. These conditions place special demands on transport equipment for moisture resistance, sink resistance, and maneuverability.

Challenges Faced

Extreme tropical humidity: Annual rainfall at the mine exceeds 2,000mm. Underground tunnels are constantly wet and waterlogged. Standard mining trucks frequently experience electrical system and brake system failures, seriously affecting availability.

Narrow tunnels and soft floor: Limited by the ore body conditions, the main haulage tunnels have restricted width. The floor consists of soft laterite nickel ore layers. Heavy trucks are prone to sinking or slipping, reducing haulage efficiency.

Long parts supply lead times: Indonesia is an archipelago. The mine is located on a remote island, and equipment parts must be transshipped through Jakarta or Makassar. Logistics lead times are long. When equipment breaks down, the cost of waiting for parts is extremely high.

Rising safety compliance requirements: Indonesia's Ministry of Mines has been strengthening safety supervision of underground equipment in recent years. Mining transport vehicles must have comprehensive braking systems and rollover protection certification.

Beijun Solution

Shandong Beijun Group provided a haulage solution centered on the UQ-12 reinforced underground dump truck, tailored to the tropical rainforest conditions of the Indonesian nickel mine. In May 2025, the Indonesian client made a special visit to the Beijun factory for an on-site inspection, gaining a comprehensive understanding of the equipment's production processes and quality control system.

Primary Equipment: Beijun UQ-12 Reinforced Underground Dump Truck (12-Ton Class)
   Powered by a proven Yuchai engine + Fast transmission + Hande axle powertrain chain. Equipped with Beijun's proprietary wet brake system and a 700L high-strength cold-riveted frame. The vehicle holds FOPS/ROPS certification. The 12-ton payload and compact body dimensions match the Indonesian nickel mine's narrow tunnels and moderate single-trip ore output.

Moisture protection for tropical conditions:
   The electrical system uses high-grade waterproof and dustproof connectors. Hydraulic line fittings are reinforced for sealing, adapting to the high-humidity underground environment and reducing electrical failure rates caused by moisture ingress.

Localized parts and after-sales support:
   Beijun products already have a delivery record in Indonesia and the Southeast Asian market. Parts for core assemblies (Yuchai engine, Fast transmission, Hande axle) can be sourced locally in Indonesia through construction machinery channels. Strong parts commonality effectively relieves the downtime pressure caused by long archipelago logistics lead times.

Implementation Results

Equipment availability guaranteed: The UQ-12 reinforced version operates stably in the high-humidity underground environment of the Indonesian nickel mine. The wet brake system has shown no degradation in braking performance due to moisture. Daily availability meets the mine's operational requirements.

Cooperation reached after client on-site validation: During the factory visit, the Indonesian client focused on the laser cutting tolerance control on the assembly line and the key process inspection procedures, expressing recognition of Beijun's manufacturing standards. After watching the pre-delivery dynamic tests, the client representative confirmed the equipment's performance in braking, steering, and system stability, and subsequently moved forward with the procurement cooperation.

After-sales response recognized: Leveraging its service network in the Southeast Asian market, Beijun provides core parts supply and technical support for the Indonesian client. The client reported that parts procurement channels are smooth and maintenance costs are manageable, meeting the needs of long-term operation in a tropical rainforest mining area.
