Tracked Spiral Scraper Conveyor

The ZOOMRY Tracked Spiral Scraper Conveyor is a core piece of equipment designed specifically for handling bulk materials in complex terrains, with its 400mm wide tracks (optional rubber or steel) as the key advantage, integrating the flexible operation of a sand scraper with the weather-resistant characteristics of a muck scraper, achieving a wide throughput range of 100-2000 tph. Equipped with a spiral scraping system (500-800mm outer diameter) and an 800-1600mm wide conveyor belt, supporting 100-meter wireless remote control operation, it can operate stably in soft mine sites or rugged open-pit stockyards without requiring site leveling, completing bulk material scraping and conveying. Certified by international standards such as CE and EAC, it is the preferred choice in the fields of sand and gravel scraping and open-pit mine bulk material handling, offering "strong terrain adaptability, flexible operation, and high wear resistance." It can also serve as a front-end scraping device in coordination with the spiral scraper conveyor for loading.

Core Functions of the Tracked Spiral Scraper Conveyor

As a specialized scraping device focused on "terrain adaptability," the core competitiveness of ZOOMRY’s Tracked Spiral Scraper Conveyor lies in "all-terrain track adaptability + operational stability during movement + wide-range scraping capacity." Addressing the pain points of traditional wheeled scrapers, such as "getting stuck in complex terrains and limited operational range," it resolves issues like "high site preparation costs, equipment mobility challenges, and discontinuous material scraping" through optimized track structure and functional synergy, while meeting global customers’ dual demands for "international compliance and durability."

400mm Track Chassis

The equipment is equipped with a standard 400mm wide track chassis, offering two configurations to precisely adapt to different terrains:

• Rubber Tracks: Model 4009068, with an effective length of 2.9m, made of high-elasticity, wear-resistant rubber material, with a ground pressure of only 0.07 MPa, just one-third that of traditional wheeled scrapers. This design evenly distributes the equipment’s weight on soft ground (such as mine tailings ponds or rain-soaked open-pit stockyards), preventing entrapment while the rubber material avoids damaging site infrastructure (such as temporary stockyard roads). The minimum turning radius is 5m, allowing flexible adjustment of scraping positions even in narrow gaps between material piles.
• Steel Tracks: Model 40013554, with an effective length of 3.6m, made of Q355B high-strength steel plates with surface carburization and quenching treatment (hardness HRC58-62), offering 80% higher wear resistance than standard steel tracks. Designed for hard, rough terrains (such as rocky mine stockyards or hard surfaces in construction material plants), they resist scratches from sharp materials, extending track lifespan. Track tension is adjusted in real-time via the hydraulic system to adapt to changes in ground hardness, reducing the risk of track deviation.

Both track types use a "hydraulic motor + planetary reducer" drive combination, with a single motor delivering an output torque of 3500 N·m, enabling smooth start-stop and linear/turning movements even under full load. Combined with hydraulic shock absorbers in the chassis, the equipment’s vibration amplitude is controlled within 3mm on uneven terrain with slopes ≤15°, ensuring scraping stability during movement and preventing material spillage.

Spiral-Track Coordinated Scraping

The equipment adopts a "spiral scraping unit and track chassis coordinated design," distinguishing it from fixed scrapers’ "stationary operation + frequent repositioning" mode, allowing continuous scraping during track movement. The spiral system, with a 500-800mm outer diameter and 2-3.2m scraping width, efficiently captures bulk materials, with 6-8mm thick blades lined with high-strength alloy teeth (hardness HRC60) capable of breaking lightly caked materials (such as wet coal or sticky sand and gravel in open-pit stockyards), reducing scraping blockages. The scraped materials are directly transported to downstream equipment (such as conveyors or silos) via a 12-15m long conveyor belt, with a 4-meter discharge height matching the infeed height of mainstream transfer equipment, eliminating the need for secondary lifting.

This "mobile scraping + stable conveying" mode expands the operational range by twofold compared to fixed scrapers. In open-pit mine scenarios with multiple material piles, it eliminates the need for frequent trailer repositioning, with a single tracked spiral scraper conveyor covering a 50-meter diameter operational area. Scraping efficiency is improved by 35% compared to traditional equipment, making it particularly suitable for mining operations with "multiple scattered material piles and complex terrains."

100-Meter Wireless Remote Control

The equipment’s electrical control system is centered on "track movement and scraping coordination," equipped with a stainless steel rainproof control cabinet (IP65 protection) and a 100-meter wireless remote control handle. The remote handle supports full-function operations, including "track movement, spiral speed adjustment, conveyor belt start-stop, and emergency shutdown," allowing operators to observe material pile conditions from a safe area (such as a mine observation platform or stockyard control room) and adjust equipment position and scraping parameters in real-time. For example, during operations on soft ground, the remote control can fine-tune track steering to avoid single-side entrapment; in multi-pile scenarios, it enables slow track movement for "scraping while moving," eliminating the need for manual close-range equipment repositioning, significantly enhancing operational safety and efficiency.

Additionally, the control system supports multi-language switching (English, Russian, Spanish, Chinese), with an operator interface focused on "track-scraping coordination" design, allowing one-touch recall of three terrain-adapted parameter sets (e.g., track speed for soft ground or spiral speed for hard ground). This enables operators in different global regions to quickly master the equipment, reducing training costs.

Core Components

The long-term reliable operation of ZOOMRY’s Tracked Spiral Scraper Conveyor relies on a targeted design centered on "track durability, ample power, and coordinated stability." From the track chassis to the spiral scraping system, each component undergoes simulated testing in complex terrain conditions and international standard verification, ensuring adaptability to global multi-terrain bulk material operations.

Track Chassis System

The track chassis is the key to adapting to complex terrains, with core components reinforced beyond the dual track configurations. Track connecting pins are made of 40Cr forged material with surface phosphating treatment, improving rust resistance by 60% to prevent jamming in high-humidity mine environments. The drive and guide wheels are integrally forged from steel, with wheel teeth surface-hardened to HRC60, extending wear resistance to over 10,000 hours. The chassis frame is welded from Q690 high-strength alloy steel, optimized for stress distribution through finite element analysis, with frame deformation ≤2mm under full-load movement, ensuring coordinated stability between the spiral and conveyor belt.

The hydraulic system driving the tracks is powered by an 11-18.5 kW hydraulic pump station (11 kW for rubber tracks, 15-18.5 kW for steel tracks and large spirals), with a 200L oil tank capacity and triple filtration (10μm precision), achieving NAS 8 hydraulic oil cleanliness to prevent track drive failures due to impurities. The pump station and track motors are connected with high-pressure hoses (30 MPa working pressure) and stainless steel fittings, offering excellent corrosion resistance for dusty mines or high-salinity port environments, with an annual system failure rate below 0.5%.

Spiral Scraping System

The spiral system is the core execution unit for "mobile scraping," designed for "impact resistance and low residue." The 6-8mm thick blades are lined with high-strength alloy teeth (single tooth hardness HRC62), connected to the blades via bolts, allowing individual replacement of worn parts within 2 hours. The spiral shaft is made of 45# seamless steel tubing (diameter ≥150mm), with self-aligning bearings at both ends to compensate for slight vibrations during track movement, preventing material jams.

The drive unit uses a 22-75 kW high-power motor, precisely matched to throughput needs (22-37 kW for 100-500 tph, 45-55 kW for 500-1200 tph, 75 kW for 1200-2000 tph), with an IP55 protection rating to withstand rain and dust in open-pit mine operations. The accompanying gearboxes offer three models: ZQ350 dual output, ZQ400 dual output, and ZLY250 hardened gear dual output, with the hardened gear model achieving 97% transmission efficiency and 50% higher load capacity than standard models, capable of withstanding sudden impacts from large material chunks during track movement, preventing drive interruptions.

Conveyor Belt System

The conveyor belt system, as the link between "scraping and transfer," is designed for "anti-slip and leak-proof" performance. The belt width ranges from 800-1600mm (800-1000mm for 100-800 tph, 1200-1600mm for 800-2000 tph), made of nylon-core anti-slip rubber with a longitudinal tensile strength of 1600 N/mm. The surface features an 8mm deep diamond-patterned anti-slip design, improving slip resistance by 40%, preventing slippage of wet materials (such as wet coal or sticky sand and gravel) during track movement. The belt is equipped with 350mm high wear-resistant rubber side skirts with embedded steel wire frames, reducing material leakage and meeting the needs of "continuous conveying during movement."

The drive uses a 15-30 kW electric drum (no additional motors or gearboxes required), offering a compact structure and easy maintenance. The electric drum has built-in overheat protection (automatic shutdown above 120℃) to prevent belt overload burnout during track movement. The 12-15m belt length, paired with a 4-meter fixed discharge height, directly connects to downstream conveyors or silos, eliminating secondary transfer and reducing losses in track-moving operations.

Modular Transportation and Efficient Installation

Addressing the pain points of global customers regarding "complex terrain project transportation difficulties and long installation cycles," ZOOMRY’s Tracked Spiral Scraper Conveyor adopts a "track module prioritized disassembly + high pre-assembly ratio" design, ensuring all-terrain performance while significantly reducing cross-border transportation and on-site installation barriers, meeting project demands in various regions.

Modular Disassembly

The equipment can be disassembled into four standard units: track chassis module, spiral scraping module, conveyor belt module, and electrical control module, each sized to fit a 40-foot high-cube container (12.03m long × 2.35m wide × 2.69m high). The track chassis module, with hydraulically folded track plates, reduces height to 2.4m and weighs ≤22 tons (rubber tracks) or ≤25 tons (steel tracks). The spiral and conveyor belt modules are split into 2-3 segments, each ≤6m long and ≤10 tons. The electrical control module is integrated into a waterproof enclosure, requiring no special transport permits.

Compared to traditional tracked equipment requiring "special transport + oversized customs clearance," cross-border logistics costs are reduced by 40%. Core components (such as track plates and spiral blades) are factory-sealed with rustproof and anti-collision packaging, preventing damage from jolts during transport, meeting logistics needs in regions like Europe, Southeast Asia, and Africa.

High Pre-Assembly Installation

The equipment is 85% pre-assembled at the factory, including track-to-chassis connections, spiral-to-motor debugging, initial hydraulic pipeline connections, and electrical control system parameter calibration, undergoing 80 hours of "complex terrain simulation" full-load testing (e.g., 12° slope uneven terrain, alternating soft-hard ground) to ensure fault-free on-site installation.

On-site installation requires only three core steps: first, modular unit assembly using high-strength bolts to connect the track chassis and spiral module, completable by two people in 2.5 hours; second, final hydraulic pipeline and electrical plug connections using quick-connect fittings for leak-free assembly, taking ≤1.5 hours; third, no-load testing to verify track steering, spiral scraping, and conveyor belt coordination, completable by a skilled team in one day for full commissioning. ZOOMRY provides a multi-language technical manual with track operation guidelines, accompanied by 24-hour online technical support via video guidance to resolve customer installation queries, enabling deployment without a professional tracked equipment installation team.
