SQZ4500B Super Heavy Articulated Lorry Crane 100ton Low Clearance Folding Boom Crane 23.9m Radius For Petrochemical Industrial Hoisting

Product Description

The SQZ4500B hydraulic folding boom crane is a top-tier ultra-heavy load lifting equipment, specially developed for super-large hoisting tasks that conventional telescopic cranes and ordinary folding cranes cannot accomplish. It adopts premium high-strength 12-sided polygonal steel boom and integral one-piece box frame forging technology, which greatly enhances overall bending resistance, torsion resistance and structural stability, effectively eliminating boom jitter and deformation during full-load and long-radius operation to realize precise heavy-load positioning.

Equipped with optimized multi-section telescopic folding boom system, the crane achieves a maximum working radius of 23.9m, covering an ultra-wide operation range and reducing frequent vehicle position adjustment to greatly improve construction efficiency. It adopts advanced dual-pump confluence large-flow hydraulic system, featuring fast lifting response, stable power output, low energy consumption and excellent continuous working performance. Built-in multi-stage hydraulic buffer protection devices ensure smooth and steady boom extension, retraction and luffing, minimizing equipment wear and extending service life.

The integrated rotary table and counterweight box design optimizes the overall force transmission structure and further improves operation stability under ultra-heavy loads. Supported by dual high-torque reducers and full hydraulic slewing drive, the crane realizes 360° dead-angle-free full rotation for all-directional flexible operation in complex construction sites. Full-span multi-stage telescopic reinforced hydraulic outriggers expand the supporting area comprehensively, providing ultra-high safety and stability for 100-ton super-heavy hoisting. It supports intelligent upgrades including wireless remote control, real-time load monitoring and automatic overload protection. All finished cranes undergo strict full-load factory testing and aging inspection to ensure stable and durable operation in harsh industrial environments.
