Parts for SQS157-5 6.3-Ton 5-Section Straight-Boom Crane

The SQS157-5 is a 6.3-ton, 5-section straight-boom crane featuring a high-strength octagonal boom and a synchronized telescoping mechanism. With a maximum lifting capacity of 6.3 tons, a boom reach of 12.9 meters, and a lifting height of approximately 15 meters, it offers a wider operating range than standard 4-section models. It effectively addresses challenges such as heavy loads, distant positioning, and reach limitations encountered during construction, equipment installation, and long-range loading/unloading. The crane supports 360° continuous rotation and utilizes an upper-seat control configuration, providing operators with superior visibility for monitoring lifting points and the surrounding environment. Its outriggers extend to approximately 4.92 meters and feature dual-side linkage controls, enhancing on-site stability and operational convenience. Integrated features—such as a centralized control panel, remote engine start/stop, electronic throttle, automatic hook stowage, and an efficient cooling system—minimize the need for the operator to frequently climb down, thereby boosting continuous operational efficiency and improving hydraulic system heat dissipation. Customers who already own a local truck chassis can purchase the crane unit separately for installation; this approach reduces costs associated with vehicle procurement, international shipping, and modification, making it an ideal solution for overseas clients who prioritize extended operating radii, high operational efficiency, continuous duty capabilities, and optimized total cost of ownership.
