In the bulk material handling industry, mobile truck unloaders, with their flexible maneuvering, connect diverse transportation scenarios, while fixed systems, with their stable rigid structures, support large-scale transfer needs. As core equipment linking the transportation and processing links, their selection directly affects an enterprise's operational efficiency and cost control.
When a mine needs to quickly respond to unexpected material transfer demands, should it choose mobile equipment that can rush to the site at any time, or rely on a stable system with fixed infrastructure? When a port faces a short-term freight peak, should it invest heavily in building a fixed unloading line, or use flexibly deployable mobile equipment to cope with the fluctuations? Behind these decisions that hit the industry's pain points lies an in-depth consideration of the core values of the two types of equipment.
A mobile truck unloader is a modular device integrating a traveling mechanism, a unloading conveying system, and a power unit. Its core design concept is to achieve free movement across the entire site through a wheeled or tracked chassis, combined with adjustable unloading height and multi-angle operating range, to meet the rapid unloading needs in multiple scenarios. The equipment usually adopts a foldable structure design, which can be transported as a whole through a 40-foot high container, and on-site assembly only takes 10-20 days, greatly reducing the installation threshold.
Zoomry Heavy Industry's mobile truck unloaders cover a processing capacity range of 200-1800 tons per hour, with belt widths of 1400-1800mm and a maximum unloading height of 6.3 meters. Equipped with a hydraulic drive system and a PLC intelligent control system, they support remote operation and automated unloading processes, reducing manual intervention while lowering the risk of material spillage and dust pollution.
Fixed unloading systems usually consist of concrete foundations, fixed conveyor belts, silos, and supporting dust removal equipment, realizing material transfer through preset tracks or chutes. Such systems' design needs to be deeply bound to the site infrastructure. For example, in ports and large mines, fixed systems are often rigidly connected with crushing stations and stockyards. Their advantage lies in achieving ultra-large processing capacity (some systems can reach more than 3000 tons per hour), and controlling dust and noise pollution through fixed sealed structures.
However, the limitations of fixed systems are also obvious: the infrastructure cycle is 3-6 months, the initial investment cost is high, and it cannot adapt to site change needs. Once the production line layout is adjusted, the entire system may face the risk of scrapping.
Fixed systems are more suitable for large industrial parks and long-term logistics hubs. For example, in coal-fired power plants, fixed unloading systems are connected to coal storage silos through underground corridors, enabling closed transfer of coal and meeting the strict requirements of environmental regulations on dust emissions. In addition, in scenarios with stable flow such as railway freight stations, fixed systems can achieve 24-hour continuous operation through automated control systems, reducing labor costs.
But it should be noted that fixed systems have higher requirements on geological conditions. In earthquake-prone areas or with unstable foundations, their rigid structures may face safety risks, while the flexible design of mobile equipment has more advantages.
Tracked models of mobile truck unloaders can travel on 30-degree slopes and soft ground, while wheeled models can achieve rapid leveling through hydraulic jacks, adapting to different site flatness requirements; they also support real-time adjustment of unloading height (3-6.3 meters) and angle, and can switch from truck unloading to ship loading operations within 5 minutes. By replacing wear-resistant belts and adjusting conveying speed, they can handle materials of different densities such as coal, ore, and sand, avoiding the need for re-transformation of fixed systems due to changes in material properties.
The rigid structure of fixed systems makes them difficult to cope with changes in working conditions. For example, when the material particle size increases from 50mm to 100mm, fixed chutes may be blocked, while mobile equipment can quickly adapt by adjusting the size of the receiving hopper grille.
Mobile truck unloaders adopt fully enclosed receiving hoppers and rubber skirt designs, combined with optional fog cannon dust removal systems, which can control dust emissions below 0.5mg/m³, meeting EU CE certification and Russian EAC certification standards. In terms of safety design, their advantages lie in emergency response capabilities, equipped with dual braking systems (hydraulic braking + mechanical locking), which can lock the conveying mechanism within 0.01 seconds in case of power failure to prevent material falling. The remote control function also allows operators to monitor operations from 50 meters away, avoiding close contact with dust and noise (equipment operating noise ≤75dB).
Fixed systems can achieve efficient filtration through bag filters, but need to be equipped with complex ventilation pipes, resulting in high construction costs. Moreover, during equipment maintenance, their enclosed structure may lead to dust accumulation, increasing safety hazards.
From the perspective of long-term operation, mobile equipment has better energy efficiency performance. Zoomry Heavy Industry's electro-hydraulic system saves 30% energy compared with traditional mechanical transmission. When operating at full load, the power of the 1800mm belt model is only 45kW. At the same time, the modular design makes maintenance more convenient; for example, idler replacement can be completed within 2 hours.
The initial energy consumption of fixed systems is low, but with the increase of service life, the wear of their pipes and chutes will lead to increased energy consumption. According to statistics, the energy consumption of fixed systems after 5 years of operation increases by 25% compared with new equipment. Moreover, similar maintenance may require more than 12 hours of shutdown, while the replacement cost of vulnerable parts of mobile equipment is lower, and long-term maintenance costs can be saved by 40%.
