SQZ3600B Super Heavy Articulated Lorry Crane 90ton Low Clearance Folding Boom Crane 23.4m Lifting Height For Industrial Heavy Hoisting

Product Description

The SQZ3600B hydraulic folding boom crane is an upgraded ultra-heavy load lifting device, customized for super-large hoisting scenarios that conventional folding and telescopic cranes cannot undertake. The whole machine adopts high-strength integral polygonal steel boom with integral forging and precision welding technology, which greatly enhances overall structural rigidity, anti-bending and anti-torsion performance, effectively avoiding boom deformation and jitter during full-load and long-radius heavy operation.

Configured with a multi-section telescopic folding boom system, the crane realizes a maximum working height of 23.4m and a maximum working radius of 20.7m, balancing ultra-long reach and flexible folding storage. It adopts advanced dual-pump confluence hydraulic system with large-flow oil supply, featuring fast lifting response, stable power output and high working efficiency. The built-in multi-stage buffer protection structure of the hydraulic cylinder ensures smooth boom extension, retraction and luffing, reducing equipment wear and improving operation accuracy.

Equipped with dual high-torque reducers and full hydraulic slewing drive, the SQZ3600B supports 360° continuous dead-angle-free rotation, adapting to all-directional operation in complex construction sites. The full-span multi-stage telescopic hydraulic outriggers expand the supporting area comprehensively, providing ultra-high stability for 90-ton super-heavy load operation. Compatible with various multi-axle heavy-duty truck chassis, the crane supports intelligent upgrades including wireless remote control, real-time load monitoring and overload self-protection. All finished cranes pass strict full-load factory testing and aging inspection to ensure stable performance, ultra-low failure rate and long-term durable operation in harsh industrial environments.
