ZOOMRY
Protable truck unloader Conveyor is a mobile equipment designed to receive bulk materials from trucks via a hopper and transfer them to designated locations through a belt and telescopic arm system. Its core value lies in rapid deployment and adaptability to complex terrains, making it ideal for scenarios such as iron ore transshipment in ports, coal transfer in mines, and grain unloading in silos. For example, Zoomry Heavy Industry’s ZRLD-TU series truck unloader conveyor can be installed and commissioned within 48 hours, with a single-unit throughput of 200–1,800 tons/hour. In an Indonesian nickel ore port, this solution reduced truck queuing time by 60%, increasing daily unloading capacity to 12,000 tons.
Working Principle of the Mobile Truck Unloader
The protable truck unloader receives bulk materials dumped by trucks into its hopper. The materials are evenly distributed onto the Conveyor Belt via a vibrating feeder and then transported to stockyards or downstream equipment through a hydraulically driven telescopic arm (15–45 meters in length). The core process involves three stages:
- Material Reception: The hopper uses wear-resistant steel plates (Hardox 450) and a grating screening structure to filter oversized impurities (≤300mm), preventing blockages.
- Belt Conveyance: A tear-resistant EP800/4 belt (longitudinal tensile strength ≥800 N/mm) operates at 0.3–4.5 m/s, paired with a hydraulic auto-tensioning system to limit slippage to ≤3%.
- Telescopic Positioning: A truss-style telescopic arm, controlled by proportional valves (±15° adjustment), covers a radius of 120 meters and adapts to truck heights of 1.5–4 meters.
Technical Advantages:
- Modular Mobility: The Mobile Truck Unloader is disassembled into modules ≤35 tons, compatible with 40-foot container shipping. On-site assembly time is reduced by 80% compared to fixed systems (e.g., 20-day commissioning for 6,000 tons/hour capacity in Manzanillo Port, Mexico).
- Intelligent Control: Protable Truck Unloader Integrated PLC and LiDAR enable real-time material flow monitoring (±2% accuracy) and automatic belt speed adjustment, stabilizing energy consumption at 0.18 kWh/ton (vs. 0.35 kWh/ton for traditional systems).
- Full-Environment Durability: C5-M anti-corrosion coating (ISO 12944) and IP66 protection ensure continuous operation in extreme conditions, from -30°C (Siberian coal mines) to 50°C (Saudi phosphate mines), with an annual failure rate <1.2 incidents.

FAQ: Common Questions About Truck Unloader Conveyor
-
Q: Can the equipment handle high-viscosity materials (e.g., wet clay)?
A: Customizable high-frequency vibrating hoppers (3–5 mm amplitude) and PTFE liners reduce adhesion to ≤2%. Proven in Indonesian laterite nickel ore projects, handling 50 Pa·s slurry with >95% uptime. -
Q: How is integration with existing conveyor systems achieved?
A: Flange connections (ISO 5293) and PLC communication protocols (Modbus TCP/IP) ensure ≤±10 mm alignment accuracy. In large coal mine projects, seamless integration with tubular conveyors achieves full capacity within 3 days. -
Q: How is reliability ensured in extreme climates?
A: Standard -45°C hydraulic oil modules and 50°C air-cooled systems. At Norilsk Nickel (Russia, -40°C), core component replacement rates dropped by 63% over 3 years.
