ZOOMRY Mobile Telescopic Stacker is a self-propelled, wheeled bulk material stacking system engineered for high-capacity, flexible stockpile operations in mining, ports, cement plants, and industrial sites. Integrating a hydraulic telescopic boom extending up to 55 metres, a 360° slewing ring, and a remote-controlled wheeled chassis, the unit enables efficient material management across multiple job sites with minimal setup time. Compared to tracked radial stackers, the wheeled configuration provides faster travel speeds on prepared surfaces and lower undercarriage maintenance costs — ideal for long-term operations where mobility between stockpile zones is frequent and ground conditions are well-established. Since 2005, ZOOMRY has delivered over 200 telescopic stacker units to more than 30 countries, built to CEMA and ISO standards with CE and EAC certifications.

How Does It Work?

The Mobile Telescopic Stacker operates through a continuous material handling sequence:

• Material intake: Bulk material is fed via a hopper, apron feeder, or feeding conveyor onto the main belt, which transfers it to the telescopic section.
• Telescopic extension: The conveyor boom extends hydraulically (up to 55 metres) to reach across the stockpile without relocating the machine, reducing auxiliary equipment requirements.
• Radial slewing: The 360° slewing ring enables radial rotation, creating layered conical stockpiles with uniform particle distribution — critical for minimizing segregation in coal, aggregates, and mineral ores.
• Inclination adjustment: The hydraulic lifting system adjusts the boom angle up to 20°, controlling stacking height and reducing material degradation during discharge.
• Remote mobility: The self-propelled chassis with wireless remote control allows the stacker to be repositioned quickly between stockpile zones or job sites — no towing vehicle required.

Key Technical Advantages

Automated Stockpiling

The stacker supports optional PLC-based automation with pre-programmed layering sequences, radar or laser volume monitoring, and integration with plant DCS or SCADA systems. This enables consistent pile formation, reduced operator workload, and real-time inventory tracking — particularly valuable for port and large-scale mining operations where multiple stockpiles of different material grades must be managed simultaneously.

High Portability

The self-propelled wheeled chassis allows the stacker to be quickly relocated between stockpile zones or job sites. Unlike fixed radial stackers that require permanent foundations, the mobile stacker drives itself to the next position — hydraulic outriggers enable fast setup and repositioning in minutes. This makes it the preferred choice for multi-site operations, contract crushing and screening projects, and temporary stockpile requirements.

Versatile Material Handling

The equipment handles a wide range of bulk materials including coal, iron ore, limestone, aggregates, grain, and fertilizer — all with a single machine. The telescopic layering method (commonly referred to as the "Chevron" or "windrow" method) minimizes particle segregation, degradation, and contamination — preserving material quality across different product types. For abrasive materials such as iron ore and granite, wear-resistant Conveyor Belts can be specified to extend service life.

Direct Loading

The stacker can receive material directly from feeding conveyors, trucks, or wheel loaders, eliminating the need for intermediate transfer equipment. When paired with a grasshopper conveyor or hopper feeder, the system forms a complete mobile receiving-to-stockpiling solution — reducing material handling stages, lowering operational costs, and minimizing spillage risks.

Additional Advantages

• Eliminates loader dependency: Replaces wheel loaders for stockpile building, reducing labour and fuel costs — electric drive options available for further energy savings.
• Space-saving retractable design: The boom retracts when not in use, reducing storage footprint and improving site safety during idle periods.
• Reduced dust and spillage: Controlled material flow and precise boom positioning minimise environmental impact; optional dust suppression systems including galvanised covers, extraction units, and water spray are available.
• Low maintenance: Robust construction with accessible service points reduces downtime and maintenance costs — standardised conveyor rollers and pulleys simplify spare parts management.

Common Applications

• Ports and coal terminals: High-capacity stacking of coal, iron ore, and aggregates for export/import operations, with rapid relocation between berths as vessel schedules change.
• Mining and ore processing: Stockpiling copper, bauxite, and other ores with high throughput and minimal fines generation — serving multiple stockpile zones from a single machine.
• Cement plants: Continuous stacking of limestone, clinker, and additives for kiln feed preparation — mobility enables the stacker to serve both raw material and finished product storage areas.
• Quarry and aggregate production: Stacking crushed stone, sand, and gravel with controlled layering to maintain size consistency and reduce segregation.
• Grain and agricultural terminals: Gentle handling of wheat, corn, and rice with telescopic layering to prevent kernel damage and spoilage during long-term storage.

Structural Components

Component list: 1-Hydraulic lifting system 2-Front wheel walking device 3-Hydraulic outriggers 4-Hydraulic station system 5-Base 6-Electrical control box 7-Tail wheel rotation device 8-Tow bar 9-Maintenance platform 10-Hopper 11-Main conveyor belt 12-Wire rope traction device 13-Telescopic conveyor belt

Front Wheel Walking Device: Consists of walking frame, hydraulic motor, walking tires, chain and chain guard. Connected with the base through the pin. In normal use, the hydraulic legs lift the front part of the base completely. After the tires leave the ground, remote control the front wheel walking device to the working position. After arriving, use tie rods on both sides to connect with pins, then retract hydraulic outriggers, allowing normal work or rotation.

Tail Wheel Rotating Device: Composed of tire, turntable, and bracket. The base and belt conveyor frame are installed on this bracket for 360° rotation, enabling the radial stacking function.

Electric Control Box: Bolted and installed on the base. The electric control box is the operation center of the entire stacker, and all operations are completed on the electric control box.

Inclination range: The stacker angle can be controlled between 4° and 20°.

Belt splicing: For belt conveyors and mobile telescopic stackers intended for long-term continuous operation, site vulcanizing is required. ZOOMRY can supply the vulcanizing machine with the telescopic stacker or long-distance belt conveyor system.
