GSQS400-4 16 Ton Straight Arm Truck Mounted Crane 19.3m Boom 420kN·m 4 Sections Telescopic Hydraulic Lorry Crane

Detailed Product Description

The GSQS400-4 is a flagship heavy-duty truck-mounted crane independently developed by XCMG, fully optimized for global high-intensity, heavy-load and long-duration lifting scenarios. The whole machine adopts high-grade high-strength alloy steel and integral welding & secondary stress relief technology. The upgraded thickened hexagonal boom section effectively improves bending resistance, torsion resistance and overall structural rigidity, completely solving the deformation and fatigue problems of traditional cranes under long-term heavy-load operation and greatly extending the service life.

Equipped with a professional 4-section reinforced synchronous telescopic structure, the GSQS400-4 realizes zero-jitter stable extension and retraction under full load conditions. It optimizes the loaded telescopic stability defect of traditional heavy-duty cranes, significantly improving on-site construction efficiency and operational safety. The self-developed flow-sharing proportional hydraulic system achieves precise and balanced oil circuit distribution, enabling synchronous and smooth compound operations including lifting, luffing and slewing, with sensitive response and ultra-high micro-operation accuracy to reduce operating difficulty and construction risk.

Supporting 360° full continuous rotation without any working dead angles, the crane realizes omnidirectional flexible operation and adapts to narrow urban construction spaces, complex mountain sites and large open engineering scenarios. It is highly compatible with mainstream 8×4 heavy-duty truck chassis with compact and scientific layout, retaining complete cargo transportation capacity while realizing 16-ton super heavy lifting functions. Optional configurations such as wireless remote control, auxiliary hook, aerial working bucket and intelligent torque limiting safety system further enrich functional diversity. All core hydraulic accessories adopt upgraded high-temperature resistant, low-temperature resistant and wear-resistant sealing parts, with excellent dustproof, anti-corrosion and anti-fatigue performance, adapting to long-term high-intensity operation in various harsh outdoor environments.
