Highlights
Significantly enhances bending and torsional resistance
The crane boom utilizes a high-strength steel, U-shaped cross-section, straight-arm design, which significantly enhances bending and torsional resistance. With its 5-section boom, SQS250 achieves a maximum working radius of 16.9 meters. A tandem pump hydraulic system delivers robust power for smoother combined operations. A sensitive proportional control valve provides exceptional operational responsiveness and fine control, enabling precise manipulation of heavy loads. Standard equipment includes a temperature-controlled radiator and an automatic hook retraction device.
Powerful lifting performance
SQS250 excels in delivering a balanced and exceptional combination of transport efficiency, lifting capacity, and mobility, making it a versatile performer in the truck-mounted crane industry. Its powerful lifting performance meets diverse common operational needs and is widely applied in scenarios such as construction material handling on job sites, power facility installation, machinery and equipment relocation, rescue operations, landscaping, and pipeline installation.
