XCMG GKS55A 55 m class vehicle-mounted extensible boom aerial device. 4x2 chassis with optimized 18-ton vehicle weight target — limit-matching engineering for the class, where most 50+ m aerial devices require heavier 6x4 or 8x4 chassis. Seven-section telescopic arm with heptagonal cross-section and bending side structure for arm weight reduction with operation stability. High-strength cable telescoping mechanism. Platform expands from transit width to over 3 m of working width with ground-level low position for loading. Horizontal leg status detection with automatic amplitude limiting — no forced override required for partial-spread setups.
The XCMG GKS55A is a 55 m class vehicle-mounted extensible boom aerial device on a 4x2 chassis with optimized vehicle weight controlled at 18 tons. The 18-ton vehicle weight target on a 4x2 chassis is the limit-matching engineering decision — most 50+ m aerial devices require heavier 6x4 or 8x4 chassis to manage moment loads at full extension.
The seven-section telescopic arm uses a heptagonal cross-section and a bending side structure — lighter arm body with operation stability through the working envelope. The telescopic mechanism uses high-strength cable rather than chain or rigid linkage — lighter weight and higher carrying capacity per section.
The platform expands from transit width to over 3 m of working width. At low position the platform can reach the ground for loading and unloading of goods or personnel. At high position multiple operators can collaborate on the same task — relevant for installation or rescue work above 30 m where two-person coordination matters.
Controls support multiple operation options including remote control from the platform with a separate emergency stop button. Engine start and stop can be controlled from either the turntable or the remote. Horizontal leg status detection automatically limits boom amplitude to match the extended outrigger configuration — no forced override required to complete partial-spread setups in tight access work.
