Sany SAC3500

The SANY SAC3500 is a flagship model in SANY’s all-terrain crane lineup, introduced with a focus on combining lifting power, extended reach, and operational efficiency. With a maximum lifting capacity of 350 tons, the SAC3500 is built on an innovative six-axle chassis design featuring multiple driving and braking modes, enhancing maneuverability, stability, and safety during transit and crane operations. The advanced chassis includes full-axle steering and automatic leveling systems that provide superior off-road performance and compact turning capabilities.

The crane is powered by a robust V8 diesel engine producing 440 kW (590 hp) at 1800 rpm, compliant with Euro IV emission standards. This engine supports high-speed travel up to 80 km/h while maintaining smooth handling under heavy loads thanks to a sophisticated 12-speed gearbox and differential lock system. The SAC3500 also features a powerful superstructure engine rated at 205 kW, which efficiently drives the crane’s hydraulic functions.

Equipped with a 70-meter six-section telescopic main boom, the SAC3500 utilizes a single-cylinder pin locking telescoping system that ensures high strength and stability. For added versatility, it can be configured with a luffing jib extending up to 78 meters, allowing a combined maximum lifting height of 132 meters and a working radius up to 96 meters. The luffing jib incorporates 0°–40° infinite variable luffing, enabling precise adjustment of the jib angle to adapt quickly to complex lifting scenarios.

The crane’s dual-pump hydraulic system improves operating speed and stability, using a combination of converging and diversion flows for high-efficiency single and combined actions. It features an electric proportional variable displacement piston pump, offering real-time adjustment and fine flow control for smooth and energy-efficient operations. The hydraulic system includes load-sensitive technology that automatically adjusts flow based on load conditions, ensuring efficient lifting under both heavy and light loads.

In terms of safety and operator experience, the SAC3500 incorporates a modern cab with panoramic views, ergonomic seating, advanced climate control, and a sophisticated control system that integrates load moment limiting, real-time diagnostics, and fault monitoring. The crane also comes equipped with high-precision sensors, anemometers on the boom head, and multiple hydraulic locks and valves to ensure safe and stable lifting operations.

The crane’s superlift device is self-assembling, reducing the need for auxiliary lifting equipment during rigging. This superlift system reduces boom deflection by up to 30% under long-boom conditions and increases lifting capacity by over 200% in heavy-lift applications.

Designed with ease of transport and fast rigging in mind, the SAC3500 uses modular counterweights ranging from 14 to 100 tons, which can be installed or removed via remote control. The crane also features high-performance hoisting winches with maximum speeds of 130 m/min, supporting rapid lifting cycles and minimizing downtime.

Overall, the SANY SAC3500 delivers a balanced combination of power, precision, and safety, making it an ideal choice for demanding heavy-lift operations such as bridge construction, wind turbine erection, industrial facility installations, and infrastructure projects requiring large lifting capacities with exceptional reach.
