ZOOMRY
1. Product Overview
The ZOOMRY tracked spiral scraper conveyor is core equipment designed specifically for bulk material handling in complex terrains, with a 400 mm wide dual-configuration tracked chassis (rubber or steel optional) as its key breakthrough. Integrating the flexible operational characteristics of sand scrapers with the weather-resistant performance of muck scrapers, it achieves a full capacity range of 100–2,000 tph. Equipped with a 500–800 mm outer diameter spiral scraper system and an 800–1,600 mm wide Conveyor Belt, it supports 100-meter wireless remote control operation in rugged terrains such as soft mine sites or open stockyards without requiring site leveling.
Certified by CE and EAC international standards, the equipment is the preferred solution for "strong terrain adaptability, flexible operation, and wear resistance" in gravel scraping and open-pit mine bulk material handling. It can also serve as a front-end scraper for the spiral scraper conveyor for loading, enabling collaborative operations and providing efficient bulk material handling solutions for complex terrains to global clients in mining and aggregate quarry applications.
2. Core Functions
The core competitiveness of the ZOOMRY Tracked spiral scraper conveyor focuses on "complex terrain adaptability and mobile operation stability." Addressing the pain points of traditional wheeled scraper conveyors — prone to entrapment, limited operational range, and high site preparation costs — it resolves issues of discontinuous material scraping and difficult equipment mobility through optimized tracked structure and synergistic design.
400 mm Wide Dual-Configuration Tracked Chassis
The 400 mm wide dual-configuration tracked chassis adapts to all complex terrains. Rubber tracks (model 400×90×68, effective length 2.9 m) are made of high-elasticity wear-resistant material with a ground pressure of only 0.07 MPa — merely one-third that of traditional wheeled scraper conveyors — distributing weight evenly on soft ground like mine tailings or rain-soaked stockyards. With a minimum turning radius of 5 m, flexible position adjustment is possible even in narrow gaps between material piles.
Steel tracks (model 400×135×54, effective length 3.6 m) are made of Q355B high-strength steel with carburized and quenched track plates at HRC58-62 hardness — improving wear resistance by 80% compared to standard steel tracks. The hydraulic system adjusts track tension in real-time, while the "hydraulic motor + planetary reducer" drive delivers up to 3,500 N·m output torque per motor. Combined with chassis hydraulic shock absorbers, the equipment maintains body vibration amplitude within 3 mm on slopes up to 15°.
Mobile Scraping and Conveying Synergistic Design
Unlike fixed scraper conveyors requiring stationary operations and frequent repositioning, this equipment adopts a deeply integrated spiral scraper unit and tracked chassis solution, enabling continuous scraping during track movement. The spiral system, with a 500–800 mm outer diameter and 2–3.2 m scraping width, uses 6–8 mm thick blades inlaid with HRC60 hardness alloy teeth to break up slightly caked materials like wet coal or sticky gravel. Retrieved materials are conveyed downstream via a 12–15 m long conveyor belt with a 4-meter discharge height, precisely matching feed ports of mainstream transfer equipment. This model expands the operational range by twofold compared to fixed scraper conveyors, increasing scraping efficiency by 35%.
100-Meter Wireless Remote Control System
The control system features a 304 stainless steel rainproof control cabinet (IP65) and a 100-meter wireless remote control handle, supporting track movement, spiral speed adjustment, conveyor belt start-stop, and emergency shutdown. Operators can observe material pile conditions from safe areas, adjusting equipment position and scraping parameters in real-time — reducing labor costs and enhancing operational safety in coal handling and open-pit mine environments.
3. Key Components
Tracked Chassis System
Track connecting pins are made of 40Cr forged material with phosphatized surfaces for rust prevention. Track drive and guide wheels are integrally forged steel with quenched gear surfaces (HRC60), extending wear resistance to over 10,000 hours. The chassis frame is welded from Q690 high-strength alloy steel with frame deformation under full load limited to ≤2 mm. The 11–18.5 kW hydraulic pump station features a 200 L oil tank with triple filtration (10 μm accuracy), achieving hydraulic oil cleanliness of NAS 8 with an annual system failure rate below 0.5%.
Spiral Scraper System
6–8 mm thick blades inlaid with single-tooth HRC62 hardness alloy teeth are bolt-connected for individual replacement within 2 hours. The spiral shaft uses 45# seamless steel tubing (diameter ≥150 mm) with self-aligning bearings. Drive units use 22–75 kW high-power motors with IP55 protection, matched to capacity gradients. The ZLY250 hard-tooth surface reducer achieves 97% transmission efficiency with 50% higher load-bearing capacity than standard models. For grain and similar applications, the Grain spiral scraper conveyor variant offers low-breakage handling.
Conveyor Belt System
Belt width ranges from 800–1,600 mm with nylon-core anti-slip rubber (longitudinal tensile strength 1,600 N/mm). An 8 mm deep diamond-patterned surface enhances anti-slip performance by 40%. Both sides are equipped with 350 mm high wear-resistant rubber skirts. The 15–30 kW electric drum has built-in overheat protection (automatic shutdown above 120°C). The 4-meter fixed discharge height directly connects to downstream equipment, minimizing process losses during mobile operations.
4. Global Modular Transport and Efficient Installation
Modular Disassembly Design
The equipment disassembles into four standard units: tracked chassis module, spiral scraper module, conveyor belt module, and control module — each sized to fit a 40-foot high-cube container. The tracked chassis module folds track plates hydraulically, reducing height to 2.4 m. Rubber track modules weigh ≤22 tons; steel track modules ≤25 tons. This design reduces cross-border logistics costs by 40% compared to traditional tracked equipment transport.
High Pre-Assembly Ratio
The equipment is 85% pre-assembled at the factory, undergoing 80 hours of complex terrain simulation full-load testing. On-site installation requires only three core steps: modular unit assembly (2.5 hours), hydraulic and electrical final connections (≤1.5 hours), and no-load testing — full commissioning by a skilled team in one day. ZOOMRY provides multi-language technical manuals and 24-hour online technical support.
5. Global Compliance and Quality Verification
International Certifications
The equipment has passed EU CE certification (Machinery Directive 2006/42/EC, EMC Directive 2014/30/EU), completing 13 specialized tests for tracked machinery safety including chassis load-bearing strength and emergency braking response (≤0.5 seconds). It also holds EAC certification for CIS countries, meeting -30°C low-temperature operational requirements. The equipment complies with ISO 9001 and ISO 14001 systems with fully traceable production processes.
Quality Verification
ZOOMRY's in-house testing center conducts rigorous testing: rubber tracks undergo 1,000 soft ground entrapment simulation tests; steel tracks undergo 1,000 rocky ground impact tests with wear ≤0.5 mm; the hydraulic system undergoes 72-hour sealing tests at 30 MPa with no leaks. Each unit undergoes 16 specialized tests before delivery including 15° slope climbing tests, capacity switching tests, and low-temperature startup tests.
