ZRLD-TU1800 Mobile Truck Unloader (2-Lane)

The ZOOMRY ZRLD-TU1800 Tracked 2-Lane Truck Unloader achieves a core breakthrough with its "1800mm-wide belt + 600-1800tph high capacity", accurately meeting the heavy-duty unloading needs of ports and mining industries for large trucks. The equipment has undergone specialized optimizations in heavy-duty chassis stability, high-flow material transfer, and large truck adaptability, and has obtained triple international certifications (CE/EAC/KCS). It serves as a core piece of equipment for global customers in handling heavy bulk materials such as coal and ore.

Equipment Composition and Advantages

The performance design of the ZOOMRY ZRLD-TU1800 Mobile Truck Unloader centers on customers' core needs of "large truck unloading, high-flow transfer, and heavy-duty continuous operation". Every parameter has undergone field tests under heavy bulk material working conditions to ensure stability during high-intensity operations:

• High Capacity of 600-1800tph: The equipment's capacity range exceeds the upper limit of traditional unloaders. The minimum capacity of 600tph is suitable for daily heavy-duty transfer in mining operations, while the maximum capacity of 1800tph can handle peak demand of concentrated bulk cargo arrival at ports. Equipped with a Siemens PLC frequency conversion control system, the capacity can be adjusted in real time according to the arrival density of trucks and material type. For example, when 100-ton dump trucks are concentrated for ore unloading, it can switch to the 1800tph full-load mode with one click, completing the unloading of 18 trucks per hour; during daily off-peak periods, it can be reduced to 600tph, which lowers energy consumption while minimizing no-load wear of the equipment, balancing efficiency and economy.
• Bearing High-Flow Transfer of Heavy Bulk Materials: The belt width is upgraded to 1800mm, adopting a composite structure of "double-layer polyester canvas core + 30mm-thick wear-resistant rubber". Its transverse tensile strength reaches 2500N/mm, capable of withstanding long-term impact from heavy materials such as ore and coal (maximum impact pressure ≤20kN). The belt surface is designed with diamond-shaped anti-slip patterns to prevent heavy materials from slipping during transfer, improving material transfer stability by 40% compared to ordinary belts. Meanwhile, the belt drive system is upgraded to dual SEW/FLENDER gear motors (total power 90kW), with a starting torque 50% higher than that of the single-motor design, completely solving the problem of belt jamming caused by high-flow material accumulation.
• Heavy-Duty Tracked Chassis: In response to the equipment's own weight (approximately 65 tons) and heavy-duty operation requirements, a heavy-duty tracked chassis design is adopted. The track width is increased to 800mm, the ground contact area reaches 12㎡, and the ground pressure is ≤55kPa. It can move freely on complex terrains such as muddy mining roads in mining areas and gravel yards in ports without the need for pre-paved hardened roads. The chassis frame is made of 40Cr forged steel, with key load-bearing parts thickened to 30mm. It has passed 100,000 heavy-duty rolling tests without deformation, ensuring the equipment maintains structural stability during 24-hour continuous operation.
• Customized Adaptability to Large Trucks: The total width of the hopper is custom-made to 6-8m, and the feeding height is only 1.5m, perfectly adapting to mainstream 100-ton dump trucks on the market (such as CAT 793F and VOLVO A60H) without the need to adjust the truck's unloading height. The hopper is equipped with an optimized grid structure, and the grid spacing can be customized according to material particle size (50-200mm optional), which not only filters large impurities to prevent belt jamming but also avoids fine material blockage. At the same time, it is equipped with a hydraulically driven ramp (slope 12.1%, i.e., 6.7deg), and the ramp surface is paved with anti-slip steel plates, allowing large trucks to move up and down smoothly and avoiding ramp slipping caused by rainy days or heavy vehicle rolling.

Structural Features

In view of the high capacity and heavy-duty characteristics of the ZRLD-TU1800 Mobile Truck Unloader, ZOOMRY has carried out specialized strengthening on the equipment structure. From the chassis to the transmission system, heavy-duty design standards are adopted to reduce the failure rate of the equipment during long-term heavy-duty operations:

• Load-Bearing Optimization of Heavy-Duty Tracked Chassis: The chassis longitudinal beams adopt a box-type structure design with built-in reinforcing ribs, increasing the load-bearing capacity by 60% compared to ordinary tracked chassis; the track links are made of high-manganese steel (Mn13), and the surface is quenched (hardness reaching HRC50-55), improving wear resistance by 3 times and extending the service life to more than 8 years. Meanwhile, the chassis is equipped with heavy-duty shock absorbers, which can buffer the impact vibration when large trucks unload, reducing damage to components such as belts and idlers and lowering the frequency of equipment maintenance.
• Strengthening of High-Flow Belt Transmission System: The belt rollers are made of cast steel (material ZG35CrMo) with a wall thickness of 25mm and a static balance accuracy of G4.0 class, capable of withstanding radial pressure during 1800tph material transfer (maximum pressure ≤30kN); the roller surface is covered with a diamond-shaped rubber layer (15mm thick) to increase friction with the belt and prevent belt slipping during high-flow material transfer. In addition, the belt tensioning system adopts a hydraulic automatic tensioning design, which can adjust the tension in real time according to the belt load to prevent belt deviation or material leakage caused by belt slack.
• Stability in Heavy-Duty Operations: The bottom of the ZOOMRY ZRLD-TU1800 Mobile Truck Unloader is equipped with 5 sets of heavy-duty hydraulic jacks (each with a load capacity of 30 tons), distributed in a "double-row symmetric" manner, covering the core load-bearing area of the equipment. During operation, the jacks can be synchronously lifted within 40 seconds to stably support the equipment on the ground, with the tracks completely free from load, avoiding the tilting of the machine body when two lanes are unloading simultaneously (each lane bears 50 tons). The jacks are equipped with pressure sensors and overload protection devices, which will automatically alarm when the load of a certain support point exceeds the limit, ensuring the safety of the equipment during heavy-duty operations.

Application Scenarios

Heavy Ore Transfer in Large-Scale Mining

In large-scale mining scenarios such as large open-pit mines and underground mines, it is necessary to handle heavy ore transported by 100-ton dump trucks on a daily basis (a single ore block can weigh up to 50kg). Traditional unloaders often experience shutdown failures due to insufficient capacity and poor wear resistance, making it difficult to meet the 24-hour continuous production needs of the mining industry. The 1800mm-wide belt and wear-resistant structure design of the ZRLD-TU1800 can easily carry the transfer of heavy ore, and the 1800tph full-load mode can realize the seamless connection between "trucks and crushers". Through the collaborative operation of 2 units of equipment, it can handle the ore unloading task of 200 100-ton trucks per day, improving the unloading efficiency by 70% compared to traditional equipment. The monthly failure rate of the equipment is controlled within 1%, providing stable support for continuous production in the mining industry.

Concentrated Bulk Cargo Unloading at Ports

In port scenarios such as bulk cargo-specific ports and comprehensive hub ports, after the arrival of bulk cargo ships (such as Panamax bulk carriers with a deadweight of 60,000-80,000 tons), it is necessary to quickly transfer bulk materials such as coal and grain from trucks to yards or ship loaders. If the handling is not timely, it is easy to cause truck queuing and congestion, affecting port throughput. The high capacity and tracked flexibility of the ZRLD-TU1800 can perfectly adapt to this scenario: ports can flexibly adjust the capacity (600-1800tph) according to the arrival volume of bulk cargo, avoiding energy waste caused by "using a large machine for small tasks"; the tracked design can adjust the operation area at any time according to the yard location, without frequent truck movement, reducing port site occupation. In practical applications, after the introduction of this equipment, the bulk cargo unloading cycle can be shortened by 40%, effectively improving the port's bulk cargo handling capacity.
