Introduction
It is recommended to use the model SQS450 equipped with an 8×4 heavy-duty truck chassis, featuring an extendable cargo bed length of up to 8500mm. With superior lifting performance, ultimate stability, and professional-grade configurations, SQS450 serves as a core solution for scenarios like heavy-duty relocation and large-scale infrastructure construction.
Highlights
Impact resistance
The internal star hydraulic motor delivers robust torque output in low-speed conditions, with impact resistance improved by over 50%. Dual slewing gearboxes work in tandem for smoother torque delivery and more precise positioning control.
High operational efficiency
Two-stage compound outriggers (span ≥ 7500mm) provide rigid support assurance in extreme working conditions. Dual tandem pumps + precision proportional valves + an intelligent temperature-controlled cooling system achieve precise flow distribution, ensuring both high operational efficiency and fine control.
Empowers operations in extreme conditions
As strategic-grade equipment in the heavy-load sector, SQS450 empowers operations in extreme conditions such as wind turbine installation, petrochemical maintenance, and large precast component construction.
