ZRLD-TU1800 Mobile Truck Unloader (4-Lane)

The ZOOMRY ZRLD-TU1800 Tracked 4-Lane Truck Unloader boasts core competitiveness built on "1800mm extra-wide belt + 600-1800tph high capacity + 4-lane synchronous unloading", accurately addressing the key pain points of "low efficiency in bulk unloading of heavy bulk materials and difficulty in navigating harsh terrain" faced by ports and large-scale mining operations. The equipment has been comprehensively optimized in structural strength, operational stability, and international compliance, and has obtained CE, EAC, and KCS certifications, making it the preferred solution for global customers in handling heavy bulk materials such as coal and ore.

Equipment Composition and Advantages

The performance design of the ZRLD-TU1800 Mobile Truck Unloader is fully centered on customers' needs of "reducing time consumption in bulk unloading, ensuring stable heavy material transfer, and enabling navigation in complex terrain". Every parameter has been verified through field tests under heavy bulk material working conditions to ensure reliability during high-intensity operations:

• 4-Lane Synchronous Unloading: The equipment adopts an independent 4-lane feeding structure, supporting simultaneous docking and unloading of 4 large 100-ton dump trucks. 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 hours". 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, avoiding overall shutdown caused by overload of a single lane and ensuring continuous and stable unloading of bulk materials. For example, when 5,000 tons of bulk materials arrive at a port in a single day, the ZRLD-TU1800 Mobile Truck Unloader can complete all unloading in only 5 hours, which is 4 hours less than similar 2-lane equipment.
• Wide-Range Capacity of 600-1800tph: The capacity range covers 600-1800tph, and stepless adjustment is achieved through the Siemens PLC intelligent control system: it can be set to 600tph during daily transfer in mining operations to reduce energy consumption; when bulk materials arrive at the port in a concentrated manner, it can be switched to the 1800tph full-load mode to match the unloading needs of Panamax bulk carriers (with a deadweight of 60,000-80,000 tons). The equipment has an optimized transfer design for heavy materials; the diamond-shaped anti-slip pattern on the belt surface can prevent ore and coal from slipping, improving the stability of material transfer by 45% compared with ordinary belts and avoiding efficiency loss and cost waste caused by material leakage.
• Heavy-Duty Tracked Chassis for Unimpeded Navigation in Harsh Terrain: Aiming at complex scenarios such as port gravel yards and mining muddy roads, a heavy-duty tracked chassis design is adopted - the track width reaches 800mm, the ground contact area is 12㎡, and the ground pressure is ≤55kPa. It can move freely on non-hardened roads with a slope of ≤15° without pre-laying steel plates or concrete. The chassis frame is made of 40Cr forged steel, and the thickness of key load-bearing parts reaches 30mm. It has passed 100,000 heavy-load rolling tests without deformation, ensuring the equipment maintains structural stability during 24-hour continuous operation, with a failure rate 20% lower than that of ordinary tracked unloaders.
• Low Hopper + Hydraulic Ramp for Adaptation to Large Trucks: The total width of the hopper is custom-made to 8m, and the feeding height is only 1.5m, eliminating the need to adjust the unloading height of mainstream 100-ton dump trucks (such as CAT 793F and VOLVO A60H) and avoiding time waste caused by frequent posture adjustments of trucks. The hopper is equipped with an optimized grille (with optional spacing of 50-200mm) to filter large impurities and prevent belt jamming; it is equipped with a supporting hydraulically driven ramp (slope 12.1%, i.e., 6.7deg), and the surface is paved with high-manganese steel anti-slip plates, which eliminates the risk of slipping when it rains or under the rolling of heavy vehicles, ensuring the safety of large trucks when going up and down the ramp.

Structural Features

In view of the characteristics of 4-lane bulk unloading and heavy material transfer, the ZRLD-TU1800 Mobile Truck Unloader has undergone specialized upgrades in structural strength and component durability to ensure a low failure rate during long-term heavy-load operations:

• Multi-Point Hydraulic Support: The bottom of the equipment is equipped with 6 sets of heavy-duty hydraulic jacks (with a single set load capacity of 30 tons), distributed in a "double-row three-support-point" pattern, covering the entire load-bearing area of the 4 lanes. 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 4 lanes are unloading simultaneously (each lane bears 50 tons). Tests show that the levelness error of the equipment can be controlled within ≤3mm, which effectively reduces the probability of belt deviation and extends the service life of the belt to more than 50,000 hours. 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 to prevent structural damage.
• 1800mm Extra-Wide Belt Transmission System: The belt adopts a composite structure of "double-layer polyester canvas core + 30mm thickened wear-resistant rubber", with a transverse tensile strength of 2500N/mm, which can withstand the impact of heavy materials of 20kN; the drive system is upgraded to dual SEW/FLENDER gear motors (with a total power of 90kW), and the starting torque is 50% higher than that of the single-motor design, completely solving the problem of belt jamming during 1800tph full-load operation. The rollers are made of cast steel (ZG35CrMo) with a wall thickness of 25mm and a static balance accuracy of G4.0 class. The surface is covered with a 15mm thick diamond-shaped rubber layer to increase friction with the belt and prevent belt slipping during high-flow material transfer.
• Modular Split Design for Convenient Transportation and Installation: Considering transportation costs and installation efficiency, the equipment adopts a three-module split design of "hopper - belt conveyor - tracked chassis". The maximum size of each module is controlled within the loading range of a 40”HQ container (the longest module ≤12m), reducing transportation costs by 25% compared with integral transportation. On-site installation does not require large hoisting equipment and can be completed through bolt connection and plug-in electrical connection. With the multilingual installation manual (including 3D drawings) and video guidance provided by ZOOMRY, the assembly and commissioning of the 4-lane equipment can be completed within 20-25 days - 10 days shorter than the installation cycle of similar international brand equipment, greatly accelerating the commissioning progress of customers' projects.

Application Scenarios

Concentrated Unloading of Heavy Bulk Materials at Ports

In scenarios such as bulk cargo-specific ports and comprehensive hub ports, heavy bulk materials like coal and ore are often transported in a "concentrated arrival" mode. Traditional equipment often causes truck queuing and congestion and limits port throughput due to limited handling efficiency. The 4-lane synchronous unloading and 1800tph high capacity of the ZRLD-TU1800 Mobile Truck Unloader allow flexible adjustment of capacity according to the arrival volume of bulk materials, 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 storage location of materials in the yard, eliminating the need for frequent truck movement and reducing port site occupation. In practical applications, after the introduction of this equipment, the port bulk material unloading cycle can be shortened by 40%, and the daily bulk material handling capacity can be increased from 8,000 tons to 15,000 tons, effectively improving port turnover efficiency.

Bulk Raw Material Transfer in Large-Scale Mining

In scenarios such as large open-pit mines and underground mining bases, 10,000-20,000 tons of ore raw materials need to be transferred to concentrators every day. Traditional unloading equipment requires 3-4 units to work in coordination, which not only increases equipment procurement and coordination costs but also easily leads to efficiency loss due to poor connection. The 4-lane synchronous unloading of the ZRLD-TU1800 Mobile Truck Unloader enables seamless connection of "4 trucks - 1 unloader - 1 conveyor", and directly transfers ore to ZOOMRY's ZR series belt conveyors through the belt, reducing intermediate transfer links. The low hopper design of the equipment is suitable for rapid material replenishment by loaders in mining areas; the wear-resistant hopper and belt can withstand long-term impact of ore, and the monthly failure rate is controlled within 1%, ensuring 24-hour continuous production in mining operations and helping customers reduce downtime losses by more than 500,000 yuan per year.
