The SQZ500A.5 20 Ton Knuckle Boom Truck Mounted Crane is a high-performance, heavy-duty mobile lifting solution engineered for industrial operators and commercial construction enterprises requiring robust, versatile lifting capabilities. Designed to excel in the most demanding work environments, this 20T hydraulic loader crane combines a 20000 kg maximum lifting capacity with a compact folding boom design, delivering unrivaled access to confined spaces without compromising on power or stability. Ideal for continuous heavy-duty operations, it elevates productivity across construction, industrial, port, and emergency response sectors, with a core focus on safety, reliability, and long-term performance for business-focused users.
At the heart of this heavy-duty construction knuckle boom crane is its 50 t.m maximum lifting torque and 20000 kg rated lifting capacity, delivering consistent heavy-lift performance for the most demanding jobs. Its 7840 mm outrigger span ensures exceptional stability on uneven terrain, while full 360° continuous slewing enables precise load positioning across the entire working radius, a critical advantage for large-scale commercial construction and port operations.
Equipped with a 14-meter maximum hydraulic reach, this truck-mounted folding boom crane features an innovative knuckle boom design that allows for seamless maneuvering in tight urban construction sites, narrow industrial facilities, and confined port areas. Unlike traditional straight-boom cranes, its folding design enables precise load placement in hard-to-reach areas without repositioning the host vehicle, drastically reducing setup time and improving operational efficiency.
The SQZ500A.5’s advanced hydraulic system operates at a maximum 32 MPa pressure, with a recommended flow of 80–100 L/min, delivering fast, smooth lifting performance with minimal energy loss for continuous heavy-duty use. Constructed from high-strength steel with precision manufacturing, it optimizes overall weight for easy transport and installation, while its 2500 mm transport width enables seamless navigation through narrow urban and industrial corridors. Integrated overload protection and hydraulic stabilization systems further enhance safety and long-term reliability.

This industrial mobile lifting crane is engineered for diverse heavy-duty commercial applications, with core use cases including:
Ideal for lifting heavy steel beams, concrete modules, and construction equipment in urban high-rise and tight-site construction projects, delivering precision and flexibility in space-constrained environments.
Perfect for heavy machinery relocation, material loading/unloading, and assembly line support in manufacturing facilities and warehouses, reducing operational downtime and improving workflow efficiency.
Delivers reliable performance for ship and container loading/unloading, with robust hydraulic performance to withstand harsh maritime environments and continuous high-volume operations.
Can be fitted with specialized attachments for firefighting, disaster relief, and emergency lifting tasks, enabling fast, flexible response in critical scenarios with strict time constraints.
For industrial operators, strict adherence to safety protocols and proactive maintenance is essential to maximize equipment lifespan and ensure on-site safety. Key guidelines include:
Pre-operation: Park the vehicle on firm, level ground, fully extend and secure outriggers with support pads, complete a full inspection of hydraulic hoses, control systems, and safety mechanisms, and confirm the load is within the rated capacity for the current working radius.
Operation: Never operate multiple boom controls simultaneously, maintain a minimum 10-meter distance from high-voltage lines, avoid extending the working radius while rotating a loaded boom, and never lift loads over personnel.
Maintenance: Perform regular lubrication of pivot points, boom slides, and hydraulic cylinder pins, monitor hydraulic oil levels and hose condition after each use, and tighten loose bolts promptly. All hydraulic maintenance must be completed by certified, trained personnel.
