Product Description

The Sany STC750 truck crane is engineered for high-performance heavy lifting with a maximum lifting capacity of 75 tons and a robust five-section 45-meter telescopic boom made from high-strength U-shaped steel. It includes an optional 16-meter jib, enabling the crane to reach a maximum lifting height of 61 meters. The jib can be mounted at angles of 0°, 15°, and 30°, allowing flexible job site application and improving efficiency under varied site conditions.

Equipped with a powerful inline six-cylinder diesel engine rated at 275 kW (2100 rpm) and 1550 N·m of torque at 1200 rpm, the STC750 meets Euro III emission standards. The engine offers multiple power output modes to optimize performance and reduce fuel consumption. The crane also achieves a top traveling speed of 80 km/h and features a minimum turning radius of 12 meters, providing excellent maneuverability for both urban and remote job sites.

The STC750 incorporates a state-of-the-art hydraulic system that utilizes load feedback and constant power control, enhancing lifting strength and precise micro-movement. It also features electronically controlled variable winch motors, with maximum line speeds reaching up to 130 m/min for both main and auxiliary winches. The slewing system supports full 360° rotation with a maximum speed of 2.0 r/min, ensuring smooth operation and control.

In terms of safety, the crane includes an advanced load moment limiter with ±3% accuracy, a hydraulic system fitted with balance valves and dual-way hydraulic locks, and over-roll-out and over-hoisting protection. Sensors for boom length, angle, and pressure allow for real-time monitoring and automatic safety intervention if unsafe conditions arise.

The cab is ergonomically designed with panoramic visibility, an integrated display for operational parameters, and amenities such as air conditioning, stereo radio, and an adjustable steering wheel. The outrigger system is fully hydraulic with automatic horizontal leveling and a maximum span of 6.1 × 7.6 meters, providing high stability during lifting operations.

Built for rugged work environments, the STC750’s chassis is a high-strength anti-torsion box structure. It features an 8×4 drive with manual 9-speed transmission and robust suspension systems that deliver comfort and durability. With an overall weight of 46,000 kg and optimized axle loading (20,000 kg on the front, 26,000 kg on the rear), the crane meets demanding transport and lifting requirements without compromising stability or performance.

In conclusion, the Sany STC750 is a versatile and powerful truck crane with a long reach, smart safety systems, and roadability that makes it ideal for a wide range of heavy-duty lifting applications.
