SQZ7000 Heavy Duty Articulated Lorry Crane Ultra-large Torque Low Clearance Folding Boom Crane For Petrochemical & Heavy Industrial Lifting

Product Description

The SQZ7000 hydraulic folding boom crane is a newly upgraded ultra-large torque super-heavy lifting equipment, professionally developed for ultra-extreme heavy-load hoisting scenarios in high-standard large-scale engineering. Different from conventional heavy folding cranes, the whole machine adopts aviation-grade high-strength steel and optimized 12-sided polygonal boom cross-section design, cooperating with integral forging and precision welding technology to maximize structural rigidity, anti-bending and anti-torsion performance. It completely eliminates boom jitter, deformation and offset during full-load ultra-long-radius operation, realizing high-precision positioning of super-heavy equipment.

Equipped with a multi-section optimized telescopic folding boom system, the SQZ7000 achieves an ultra-wide operation coverage range, greatly reducing frequent vehicle position adjustment and improving overall engineering construction efficiency. It adopts a premium large-flow dual-pump confluence hydraulic system with intelligent pressure regulation and multi-stage buffer protection technology, featuring fast response, stable power output, uniform lifting speed and low energy consumption. The optimized hydraulic valve group matching effectively reduces impact wear during boom telescoping, luffing and slewing, extending the service life of the entire hydraulic system and core components.

The machine adopts an upgraded integrated rotary table and integral counterweight box structure, optimizing the overall force transmission path and greatly improving structural stability under ultra-large torque loads. The dual high-torque reducer full hydraulic slewing drive system ensures stable and uniform rotary power, realizing smooth 360° dead-angle-free full rotation. The full-span multi-stage telescopic reinforced hydraulic outriggers expand the supporting area in all directions, with upgraded anti-slip and anti-sink structure, adapting to complex and harsh construction ground conditions. The SQZ7000 reserves full intelligent upgrade interfaces, supporting wireless remote control, real-time load monitoring, automatic overload protection and intelligent fault diagnosis. All finished cranes pass strict full-load aging tests and precision calibration to adapt to long-term high-intensity ultra-heavy industrial operation.
