According to data from the International Association of Ports and Harbors (IAPH), 85% of global bulk ports face challenges posed by ±4.5-meter tidal fluctuations and the loading demands of 120,000-DWT ultra-large vessels. Traditional fixed shiploaders, constrained by 28-meter telescopic ranges and rigid structures, require frequent vessel repositioning, increasing single-ship loading time by 3-5 hours. Zoomry Heavy Industry's mobile shiploader addresses these challenges with a hydraulic pitch adjustment system (-5° to +22°) and a 42-meter extended telescopic boom, enabling single-machine coverage from Panamax to Capesize vessels. In Rotterdam Port field tests, this system reduced loading cycles for 120,000-DWT bulk carriers from 42 to 28 hours while decreasing vessel repositioning by 83%.
High humidity and corrosive material properties further compromise operational efficiency. As reported by the project manager of Indonesia's Bangka Island coral sand transportation initiative, traditional chutes experienced 23% blockage rates at 18% material moisture content, while steel rollers degraded within 9,000 hours in salt-laden environments. Zoomry's mobile shiploader employs an anti-slip drive + ceramic wear-resistant system: herringbone-pattern drive rollers (friction coefficient μ≥0.45) paired with hydraulic auto-tensioning reduce belt slippage to below 3%. Chutes lined with 3mm AR400 abrasion-resistant steel (Rockwell hardness HRC58-62) and composite-coated rollers extend critical component lifespans to 18,000 hours. Operational data confirms sustained 3,800-ton/hour loading rates with energy consumption reduced to 0.22kWh/ton—42% lower than conventional systems—while eliminating chute blockages entirely.
Intelligent Hydraulic Pitch System
The ZRSL series integrates pressure sensing and proportional valve control, enabling real-time pitch adjustments (-5° to +22°) to automatically compensate for ±4.5m tidal variations. Validated through 72-hour continuous testing in Rotterdam Port, bearing temperature rise remains stable below 12°C (ISO 281 standard limit: 20°C), with vessel motion compensation response time ≤0.8 seconds.
Extended Telescopic Boom Structure
Constructed from high-strength welded steel frames (ASTM A572 Gr50) with truss support, the 42-meter boom achieves 120-meter operational radius at 45-ton self-weight. Dubai Palm Island project data confirms 5,800-ton/hour loading efficiency for 80,000-DWT barges—121% faster than legacy equipment.
Modular Rapid Deployment Solution
Split-design components limit maximum single-piece transport weight to 45 tons, compatible with standard container vessels. At Mexico's Manzanillo Port, full 6,000-ton/hour capacity commissioning was completed within 20 days post-arrival—60% faster than traditional installations.
Full-environment Durability System
C5-M anti-corrosion coating (ISO 12944), -45°C hydraulic oil thermal management, and chute anti-icing heaters ensure reliable operation from tropical rainforests to Arctic ports. Five-year operational data from Chile's Patache Port shows 63% reduction in core component replacement rates with annual maintenance costs at $83,000.

During the 2022 monsoon season, coral sand exports from Indonesia's Bangka Island faced collapse. PT Bangka Mineral's port manager Hadi Wijaya recalled: "Traditional shiploaders averaged 4.7 daily downtime hours—damp coral sand clogged chutes like concrete, leaving us unable to meet 12-million-ton annual targets despite round-the-clock repairs." Compounding the crisis, 22mg/m³ dust emissions repeatedly violated environmental regulations, risking operational shutdown.
The turning point came with Zoomry's engineering intervention. After 72 hours of onsite analysis, technicians identified the root cause: mismatched chute inclination (28°) and belt anti-slip design. The solution combined three innovations: optimized 32° chute inclination with 3mm AR400 lining (Rockwell hardness HRC58-62) increased material flow velocity by 40%; herringbone-pattern drive rollers (μ≥0.45) and hydraulic tensioning reduced belt slippage from 12% to 3%; and integrated pulse-jet bag filters cut emissions to 4.9mg/m³—below Indonesia's SNI 19-0232 5mg/m³ threshold.
The results redefined port efficiency—equipment availability surged to 96.5%, monthly throughput exceeded 920,000 tons, and annual maintenance costs plummeted from $156,000 to $83,000. Wijaya noted in acceptance documents: "Even during torrential rains, the ZSLS-4500 maintains 3,800-ton/hour output—an efficiency revolution beyond our imagination." Today, this port stands as Southeast Asia's largest coral sand hub, handling 30 million tons annually.
