Used Truck Crane SANY STC550T5

SANY STC550T5 Truck Crane is a 55-ton-class next-generation hydraulic mobile crane engineered to optimize mid-to-long radius structural placement, high-altitude stability, and smart fleet logistics. It is widely deployed across urban commercial frame erection, localized wind farm maintenance setups, modular concrete pouring tasks, and public infrastructure highway rigging.

Common Variations

STC550T5 Core: The high-capacity 5-section production profile. It comes standard with a 46-meter high-tensile U-shaped structural main boom coupled with a dual-stage 16-meter fly jib to deliver a maximum load moment of 2,033 kN·m.
STC550T5-5: A specialized structural variant built around an extended 47.5-meter main boom layout, swapping out specific light-load winching parameters for an expanded vertical hoist boundary and increased full-extension capacities.
STC550T5 Euro-Spec / Overseas: A specialized export configuration modified with localized exhaust aftertreatment modules, custom international lighting arrays, and specific axle spacing configurations to comply with regional transport compliance guidelines.

Core Advantages & Features

High-Stiffness Large-Arc Bending Profile: Outfitted with a premium telescoping structural boom fabricated from specialized ultra-high-strength steel. The high-stiffness large-arc cross-section maximizes cross-sectional bending resistance, which drastically counteracts side-deflection when pulling heavy off-center loads.
Smart Flow-On-Demand Hydraulic Balance: Features an energy-saving main circuit combining a high-displacement variable piston pump with an intelligent electronic control system. This flow-on-demand allocation minimizes oil bypass heating, pushing single-line main winching speeds up to 135 m/min while securing ultra-smooth multi-function combination.
Modular Heavy-Duty Counterweight Matrix: Engineered to utilize an adjustable, multi-combination 11-ton modular counterweight system. This ballast configuration allows fleet operators to tailor weight groupings dynamically based on the jobsite radius requirements, reducing carrier wear during transit.
SYMC Intelligent Command Network: Built around a vibration-isolated panoramic cabin featuring SANY’s proprietary SYMC digital command console. The terminal tracks comprehensive load chart vectors, active mechanical boundaries, real-time wind speeds, and features customized hydraulic speed tuning to protect operators during critical lifts.
