Sany STC500E5 Load Chart PDF + Specifications

The Sany STC500E5 was developed as part of Sany’s updated 50-ton truck crane series, emphasizing structural rigidity, intelligent hydraulic control, and improved operational efficiency. It targets infrastructure construction, industrial plant installation, municipal projects, and general building work where mobility and lifting strength must be combined within regulated transport limits.

The crane is equipped with a large cross-section U-shaped telescopic boom fabricated from high-strength structural steel. The main boom extends to 45.5 meters when fully deployed. With the installation of the lattice jib, the maximum boom and jib combination reaches 61.5 meters, significantly increasing lifting height and working range for elevated installations. The optimized boom profile enhances torsional resistance and load distribution, ensuring stability under heavy lifting conditions.

In terms of lifting performance, the STC500E5 provides a maximum lifting moment of 2,017 kN·m on the basic boom configuration. When the boom is fully extended, the maximum lifting moment reaches 1,254 kN·m, maintaining reliable performance at extended radii. The crane adopts a wide outrigger stance to support full 360-degree lifting operations, enhancing overall jobsite stability.

The hydraulic system utilizes dual variable displacement piston pumps combined with an electro-proportional main control valve. The electro-hydraulic control joystick paired with proportional main valves allows smooth and precise operation. The system supports automatic switching between flow distribution and combined flow modes, enabling faster telescoping under high-demand conditions and smoother compound movements during synchronized operations. This design improves lifting precision and operational efficiency.

The carrier adopts a reinforced G-class off-road chassis built according to 55-ton structural standards, improving torsional strength and bending resistance. The chassis width measures approximately 2.8 meters, contributing to improved stability during lifting operations. The suspension system combines durability with ride comfort, and the crane is fitted with heavy-duty steel tires to support axle loads.

Power is supplied by a Weichai WP9H336E50 diesel engine compliant with China V emission standards. The engine is matched with a Fast 9JS150TA-BRPT 9-speed manual transmission, providing efficient torque transfer and optimized fuel consumption during both highway travel and jobsite maneuvering. This drivetrain configuration ensures reliable gradeability and stable driving performance across varying terrain conditions.

Energy efficiency is addressed through dedicated upper-structure energy-saving working modes, contributing to approximately 10 percent comprehensive fuel savings during lifting operations. The integrated control system allows operators to select appropriate working modes according to load demands.

The operator’s cab is tiltable from 0° to 20°, enhancing visibility during high-angle lifting tasks. The interior layout is ergonomically designed with intuitive control placement, improving long-duration operational comfort. Integrated safety systems include load moment limiting, boom angle and length monitoring, pressure sensors, and over-hoist protection to ensure safe lifting performance.

Overall, the Sany STC500E5 represents a well-balanced 50-ton hydraulic truck crane featuring a 45.5-meter U-shaped main boom, 61.5-meter maximum boom-jib reach, 2,017 kN·m lifting moment, reinforced G-class chassis, and electro-proportional hydraulic control. Its combination of structural strength, intelligent hydraulics, and fuel-efficient powertrain makes it suitable for a broad range of medium-capacity lifting applications.
