ZOOMRY
A mobile stacker is a self-propelled bulk material handling equipment used for stacking operations in open-air material yards. Its main function is to pile continuous material flows (e.g., from belt conveyors) into regular stockpiles. Typically equipped with a tracked or wheeled chassis, it can move freely within the yard. Through the rotation and pitching of the telescopic arm, the slow movement of the entire machine (usually parallel to the stockpile), and the retractable discharge chute at the front of the telescopic arm, materials are evenly spread to form long strip-shaped stockpiles or specific-shaped (e.g., circular) stockpiles.
Classified by Travel Mode
Wheeled types
Wheeled mobile stackers use reinforced solid tires as their travel mechanism. They have a compact structure, are flexible in movement, and are suitable for quick movement on hardened and flat surfaces.
Take Zoomry Heavy Industry's ZR wheeled mobile stackers as an example. They are usually equipped with 4 or 8 ultra-solid tires and a reinforced chassis. Their conveying system has strong power (18.5-37kW), reliable chassis drive (11-15kW), and a belt conveying speed of 2.0-2.5m/s, ensuring efficient material conveying. After the equipment moves to the designated operation point, it receives materials from loaders or upstream conveyors and transports them to the end via high-speed Conveyor Belts to complete stacking.
Zoomry Heavy Industry's ZR series wheeled mobile stackers excel in high efficiency and energy saving (optimized power matching for lower fuel consumption), intelligent control (supporting remote control to improve operation accuracy and convenience), and international certifications (complying with standards such as CE, EAC, and KCS to ensure global market access).
Tracked Mobile Stackers
When the working site conditions are harsh—muddy, uneven, or with soft geology—tracked mobile stackers are the first choice due to their excellent off-road performance and ground adaptability. Examples include Zoomry Heavy Industry's ZRLD series (suitable for truck unloading scenarios) and ZRSL series (suitable for mobile ship loading scenarios).
- Structure and performance: Equipped with high-wear-resistance and high-strength tracks, with strong conveying capacity (200-3600tph), belt width of 1400-1800mm, and stacking height up to 6.5-8.0m.
- Working method and applicable scenarios: The powerful track driving force ensures stable movement of the equipment on complex terrain. The conveying arm can flexibly pitch and rotate to accurately stack materials. It is specially designed for scenarios with complex and changing terrain such as mine sites and large infrastructure construction sites.
Zoomry Heavy Industry's tracked equipment features super off-road capability (high-strength wear-resistant tracks to easily handle harsh terrain), stable and precise operation (low center of gravity design, strong bearing capacity of the conveying arm), easy-to-maintain structural design, and highly customized services to meet specific needs (such as configuring 2-line/4-line truck channels, manual/hydraulic ramps).
Classified by Functional Characteristics
Telescopic Mobile Stackers
The core feature of telescopic mobile stackers is that their conveying arms have a telescopic function, which can flexibly adjust the stacking range and significantly optimize space utilization. The equipment realizes the telescoping of the conveying arm through a rope and hydraulic winch system, and is equipped with a safety brake and an automatic locking mechanism to prevent accidental falling. Zoomry Heavy Industry's telescopic mobile stackers adapt to different stacking space requirements by easily adjusting the arm length: extending the arm to expand the stacking range, and retracting the arm to adapt to limited spaces. They are suitable for port bulk cargo areas and building material yards that need flexible adjustment of stacking ranges, and can effectively reduce material segregation, degradation, pollution, and compaction.
The core advantages of Zoomry Heavy Industry's ZR-SF series lie in efficient capacity expansion to improve space utilization, stable and safe operation (no equipment shaking), intelligent wiring system (special cable sliding design to ensure smooth movement of power lines), and a complete safety guarantee mechanism.
Fixed-Type Mobile Stackers
Fixed-type mobile stackers are equipped with a fixed-length conveying arm (without telescopic function) but retain a wheeled or tracked travel mechanism, combining mobility and high stability. Their core value lies in realizing multi-machine "cascading operations" to solve the problem of long-distance material transfer.
Structure and Performance
- Wheeled version: Adopts an 8-wheel heavy-duty design, suitable for short-distance transfer on hardened roads.
- Tracked version: Equipped with wide tracks, which can move at low speed on soft ground. Both versions have a fixed conveying arm length (12-40 meters), with a simple and solid structure and outstanding bearing capacity.
Core Value
Working method of cascading operations: Multiple grasshopper machines are precisely connected end-to-end to form a long-distance continuous conveying line for "relay-type" material intermodal transportation.
- Wheeled version: The modular connection device allows the receiving end to adjust at an angle of ±5° with the arm end of the previous equipment.
- Tracked version: Equipped with an advanced synchronous travel control system, the error is controlled within 10cm when multiple machines move in linkage.
It is suitable for scenarios such as ports and mines that require material transfer over 100-150 meters or even longer distances (for example, relaying coal unloaded from ships from the front of the wharf to the rear yard). When 3-5 units work in cascade, the total hourly conveying capacity can exceed 2000tph, which is much more efficient than a single unit. Each device can independently pitch (-3° to +20°) to adapt to terrain height differences.
Classified by Power Type
The power source of the equipment determines its deployment flexibility and long-term operating costs.
Diesel-Powered Mobile Stackers
Diesel-powered models are equipped with an integrated diesel generator set, with a built-in power source, solving the problem of operation in areas without external power.
- The diesel engine drives all systems to operate without the need for an external power supply. It is an essential choice for field mines, remote construction sites, and other areas lacking an external power grid.
- Choosing high-quality diesel engine equipment from Zoomry Heavy Industry ensures strong and reliable power; optimized design pursues the best fuel economy; the emission system meets international standards, effectively reducing on-site dust, noise, and carbon footprint; maintenance is convenient, and long-term costs are controllable.
Electric Mobile Stackers
Electric models are driven by electric motors and require an external power supply, which is more economical and environmentally friendly when operating under stable power grid conditions.
- Working method and applicable scenarios: After connecting to an external power source, it drives the equipment to operate, and the advanced electrical control system realizes precise operation. It is specially designed for fixed operation areas with stable power supply facilities such as ports, docks, and factory workshops.
- Zoomry Heavy Industry's electric equipment operates extremely stably (low vibration, low noise); has significant long-term operating cost advantages (energy consumption cost is usually lower than that of diesel engines); realizes zero on-site emissions; is safe and reliable (complete insulation and grounding protection); and is easy to install (modular pre-wiring design, using plug and socket technology to simplify on-site work).
How to Choose the Mobile Stacker That Best Fits You?
To select the best mobile stacker for your project, it is necessary to comprehensively evaluate key factors:
- Site conditions: Is the site hardened and flat? What is the geological condition (e.g., muddy, rugged)? Are there any ground bearing restrictions?
- Stacking requirements: What is the type and characteristics of the target material? What is the required peak and average processing capacity (tph)? What is the designed size of the stockpile (length, width, height/diameter)? What are the requirements for the shape and density of the stockpile (e.g., high flatness required for pre-homogenization)?
- Space and transfer: Is the yard space compact and needs efficient utilization? Does the material need to be transferred over long distances? Does the equipment need to move frequently between different stockpiles or yards?
- Energy supply: Is there a stable and reliable power grid at the operation site? If not, a diesel-powered model is necessary.
- Budget and cost: Consider the initial equipment investment cost and long-term operating costs (energy consumption, maintenance, labor, and value brought by improved utilization efficiency).
