The SQZ500A 20 ton knuckle boom truck mounted crane is a super heavy-duty hydraulic lifting system engineered for the most demanding mega-scale industrial, maritime, and infrastructure projects. As a top-tier 20 ton heavy duty hydraulic truck crane, it delivers an exceptional 20,000kg maximum lifting capacity, 50 t·m lifting moment, and a high-performance hydraulic system with 32MPa maximum working pressure, paired with full 360° slewing for unrivaled operational efficiency. Designed for large engineering contractors, port operators, and energy infrastructure enterprises, this maritime 20 ton folding boom crane combines extreme lifting power, marine-grade durability, and long-term reliability for harsh, high-intensity working environments.
This 20 ton truck loader crane for port operations handles up to 20,000kg of oversized industrial equipment, heavy steel structures, and large construction modules, with a 50 t·m lifting moment that maintains stable performance even under extreme full-load conditions.
With a 32MPa maximum working pressure and 80-100 L/min recommended hydraulic flow, it delivers smooth, precise lifting and slewing action even in harsh maritime and heavy industrial environments, with consistent performance during continuous high-load operations.
The optimized boom design, thick high-grade steel, and advanced welding technology deliver exceptional anti-vibration and anti-fatigue performance, outperforming standard market cranes and ensuring long service life in heavy-duty, high-frequency working scenarios.
Full 360° continuous slewing allows operators to handle heavy materials around the vehicle without repositioning, drastically improving efficiency in congested port terminals, mega construction sites, and narrow industrial zones.
Produced under strict ISO9001 quality management systems, every unit undergoes rigorous inspection and testing before delivery, ensuring consistent performance, safety, and compliance with global industrial standards.

This heavy duty 20 ton truck mounted crane for infrastructure is purpose-built for:
Mega Infrastructure Construction: Bridge, dam, highway, and oversized prefabricated module lifting with high precision
Heavy Industrial Equipment Installation: Ultra-heavy machinery, turbine, and transformer installation for large manufacturing plants and power stations
Port & Maritime Operations: Container handling, oversized cargo loading/unloading, and maritime equipment maintenance at ports and terminals
Large-Scale Energy & Utility Projects: Wind power, substation, and long-distance pipeline installation projects requiring extreme lifting capacity
Heavy Municipal & Urban Mega Projects: Urban bridge maintenance, large-scale municipal construction, and major roadworks with heavy lifting requirements
Prior to operation, conduct a comprehensive inspection of the job site, ensuring the truck is parked on firm, level ground with the parking brake fully engaged, and maintaining a minimum 10-meter safe distance from overhead high-voltage lines. Fully extend all outriggers with appropriate support pads, and closely monitor outrigger stability and crane tipping indicators during all lifting and slewing operations. Always follow the official load chart, and never extend the working radius while rotating a loaded boom. For maintenance, regularly inspect the boom structure for fatigue, lubricate all pivot points and hydraulic cylinder pins, check hydraulic oil levels and hose integrity, and complete anti-corrosion maintenance for maritime and coastal use.
