ZRLS-TU1800 Mobile Truck Unloader (4-Lane)

The ZOOMRY ZRLS-TU1800 Wheeled 4-Lane Truck Unloader boasts three core competitive advantages: 4-lane synchronous unloading for efficiency enhancement, 1800mm belt for load-bearing, and wheeled design for flexible maneuvering. It accurately addresses the pain points of ports, such as "slow unloading of bulk cargo arriving in concentration, long queues for large trucks, and limited site maneuverability". The equipment has achieved targeted breakthroughs in multi-lane coordinated control, medium-heavy load transfer stability, and port scenario adaptability. Having obtained CE, EAC, and KCS certifications, it has become a preferred bulk unloading solution for global customers handling medium-heavy materials like coal, ore, and bulk cargo.

Equipment Composition and Advantages

The performance design of the ZRLS-TU1800 Mobile Truck Unloader is fully centered on ports' core needs: "reducing time consumption through bulk unloading, stable transfer of medium-heavy loads, and flexible wheeled adaptation to sites". Every parameter has been verified in real port working conditions and aligns with ZOOMRY's quality philosophy of "building high-quality conveying equipment", ensuring reliability during high-intensity operations:

• Bulk Efficiency Improvement: The equipment adopts a structure of 4 independent feeding lanes, supporting simultaneous docking and unloading of 4 large dump trucks (100-ton class). Compared with traditional 2-lane equipment, the number of trucks unloaded per hour increases from 9 to 18, completely resolving the industry pain point of "trucks queuing for over 2.5 hours" in ports. Each lane is equipped with an independent level sensor and a frequency conversion control module, which can adjust the transfer speed in real time according to the material accumulation in a single lane. For instance, when a lane has excessive ore accumulation, the system automatically reduces the feeding speed of that lane to avoid overload shutdown, ensuring continuous and coordinated operation of the 4 lanes.
• Adaptation to Full-Scale Port Operations: The handling capacity ranges from 600 to 1800 tph, with stepless adjustment enabled by the Siemens PLC intelligent control system. During the off-season when small quantities of bulk cargo arrive at the port, it can be set to the 600 tph mode to reduce energy consumption; when Panamax bulk carriers (with a load capacity of 60,000-80,000 tons) arrive in concentration, it can switch to the 1800 tph full-load mode, enabling the unloading of over 15,000 tons of bulk cargo per day to match the unloading rhythm of large bulk carriers. The equipment features an optimized belt design for medium-heavy materials: the 1800mm extra-wide belt increases the transfer area by 28% compared to a 1400mm belt. The belt adopts a "double-layer polyester canvas core + 30mm thickened wear-resistant rubber" structure, with a transverse tensile strength of 2500 N/mm, capable of withstanding instantaneous ore impacts of 20 kN. The material sliding rate is ≤0.2%, 70% lower than that of ordinary belts, avoiding cost waste caused by material leakage.
• Flexible Maneuvering for Complex Port Sites: It is equipped with 4 super heavy-duty tires (1.5m in diameter and 500mm in width), with a ground pressure of ≤60 kPa, allowing free movement in scenarios such as port gravel yards and temporarily hardened roads without the need for pre-laid dedicated rails. The chassis is equipped with a hydraulic power steering system, with a turning radius of only 11m—25% smaller than that of tracked equipment—enabling easy passage through 8m-wide operation channels in ports. With a moving speed of 4.2 km/h, it only takes 10 minutes to move from the unloading area on the east side of the port to the ship loader on the west side. The site utilization rate is 60% higher than that of fixed unloaders, perfectly adapting to the needs of multi-area rotation operations in ports.
• Stable 4-Lane Operation: The bottom of the equipment is equipped with 6 sets of hydraulic jacks (30 tons load-bearing per set), distributed in a "double-row three-support" pattern to cover the entire load-bearing area of the 4 lanes. During operation, the jacks can be synchronously lifted within 35 seconds, completely lifting the wheeled chassis off the ground to avoid body tilting when the 4 lanes are unloading simultaneously. Tests show that the equipment's level error can be controlled within ≤2mm, effectively reducing the probability of belt deviation and extending the belt service life to over 50,000 hours. The jacks are equipped with pressure sensors and overload protection devices, which automatically alarm when the load of a certain support exceeds the limit, preventing structural damage and ensuring the safety of 24-hour continuous operation in ports.

Structural Characteristics

In view of the "4-lane bulk unloading and high-frequency transfer of medium-heavy loads" characteristics of the ZRLS-TU1800 Mobile Truck Unloader, ZOOMRY focuses on "load-bearing enhancement, easy maintenance, and convenient transportation" in its structural design. All core components comply with the company's independent production standards, and their quality indicators exceed the conventional requirements of the industry:

• Reinforced Frame Structure: The overall frame of the equipment is made of 40Cr forged steel, and the thickness of key load-bearing parts (such as hopper support beams and belt frame crossbeams) reaches 32mm. Verified by finite element analysis, it can withstand instantaneous material impacts of 50 tons, with a structural deformation of ≤1.5mm. The frame surface adopts a three-layer anti-corrosion process of "sandblasting derusting + cathodic electrophoresis + electrostatic spraying", achieving a salt spray corrosion resistance grade of C4. It is suitable for the humid and salt-spray-rich environment of coastal ports, with a service life 5 years longer than that of ordinary anti-corrosion equipment, reducing customers' later equipment renovation costs.
• Dual-Motor Driven Belt System: The belt drive system uses two SEW/FLENDER gear motors (with a total power of 90kW), and the starting torque is 55% higher than that of a single-motor design, completely solving the problem of belt jamming at the 1800tph full load. The drive roller is made of cast steel (ZG35CrMo) with a wall thickness of 25mm and a static balance accuracy of G4.0 class. Its surface is covered with a 15mm-thick diamond-shaped rubber layer, which increases friction with the belt and avoids belt slipping during the transfer of medium-heavy materials. 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 (adjustment range: 50-200kN). The deviation rate is ≤0.3%, reducing the failure risk by 85% compared to manual tensioning systems.
• Modular Split Design: Considering the transportation needs of port customers, the equipment adopts a three-module split design: "4-lane feeding module - belt conveyor - wheeled chassis". The maximum size of each module is ≤12m, which can be loaded into one 40”HQ container, reducing transportation costs by 30% compared to integral transportation. On-site installation does not require large hoisting equipment (only a 25-ton crane is needed) and can be completed through bolt connection and plug-in electrical connection. With the multilingual installation drawings and video tutorials provided by ZOOMRY, the customer's team can complete assembly and commissioning in 12-18 days. Each piece of equipment is accompanied by a detailed installation guide manual, which covers the docking steps of each module, electrical wiring specifications, etc., ensuring that customers can complete the installation without technical barriers.

Application Scenarios

Concentrated Unloading of Bulk Cargo in Ports

In scenarios such as bulk cargo-specific ports and comprehensive hub ports, bulk materials like coal and ore often circulate in a "large bulk carriers arriving in concentration" mode. Traditional 2-lane equipment tends to cause truck congestion and ship loading delays due to insufficient efficiency. The 4-lane synchronous unloading of the ZRLS-TU1800 Mobile Truck Unloader can quickly handle the bulk cargo arriving in concentration, and the 1800tph full-load mode can match the unloading rhythm of Panamax bulk carriers. Its wheeled design allows it to adjust the operation area at any time according to the position of the ship loader, eliminating the need for frequent truck movement and reducing port site occupation.

Bulk Raw Material Transfer in Medium-Sized Mining Operations

In scenarios such as medium-sized open-pit mines and metal mines, the daily ore transfer volume is usually 1000-2000 tons, requiring bulk processing but no heavy-load tracked equipment. The 600-1800tph handling capacity of the ZRLS-TU1800 Mobile Truck Unloader can perfectly meet such needs. Its wheeled chassis can move freely on the gravel roads of mining areas without pre-laid hardened ground. The 4-lane synchronous unloading can connect with 4 80-ton dump trucks in the mining area to realize integrated "unloading - conveying" operations. The material loss rate is controlled within 0.4%, 1.6% lower than that of traditional transfer methods, helping mining customers save 100,000-120,000 yuan in material costs annually.
