Sany SCC6300 Load Chart PDF + Specifications

The Sany SCC6300 was introduced as one of Sany’s large-capacity crawler cranes aimed at the international heavy lifting market. With a maximum lifting capacity of 630 tonnes at a 6-meter working radius, the crane was engineered to compete in the heavy crawler segment traditionally dominated by Japanese and European manufacturers. The SCC6300 uses a conventional lattice boom design combined with a superlift counterweight system to achieve high lifting performance while maintaining stability during heavy-duty operations.

The crane’s main boom can be configured from 24 meters up to 84 meters in heavy boom arrangement, while the light boom configuration extends from 36 meters to a maximum of 108 meters. For projects requiring extended reach and elevated lifting heights, the crane can be equipped with a fixed jib ranging from 24 to 60 meters or a luffing jib from 24 to 84 meters. In luffing jib configuration, the boom operating angle ranges between 30° and 85°, while the luffing jib itself can operate from 15° to 75°. The SCC6300 can also be fitted with a superlift mast system measuring up to 30 meters in length, significantly enhancing lifting charts and stability during extreme lifting operations.

The upper structure is powered by a DEUTZ BF8M1015CP diesel engine, an 8-cylinder water-cooled turbocharged engine producing approximately 480 kW at 2,100 rpm. The engine complies with modern emission standards for its generation and drives the hydraulic system through multiple variable displacement piston pumps. Sany designed the hydraulic system with open-loop and closed-loop circuits to improve operational smoothness and reduce energy loss during simultaneous crane functions. The hydraulic control system allows precise load handling and coordinated multi-function movements, which are critical during tandem lifts and heavy module installation work.

The SCC6300 utilizes multiple planetary hoist winches with grooved drums designed for high rope capacity and smooth reeving performance. The main hoisting winches deliver rated single-line pulls of 16.4 tonnes with maximum rope speeds reaching 110 meters per minute, while the superlift winch can achieve speeds up to 120 meters per minute. Wire rope diameter for the main systems is 28 mm. The main hoist rope length reaches 1,180 meters, enabling deep reeving configurations for ultra-heavy lifts. The crane’s slewing system uses a planetary gear drive with a hydraulic motor capable of continuously variable slewing speeds from 0 to 1.2 rpm.

The undercarriage features hydraulically extendable crawler frames with 1,500 mm wide crawler shoes. Ground pressure is approximately 0.15 MPa in standard configuration, helping distribute the crane’s massive operating weight effectively across soft or prepared surfaces. Traveling speed ranges from 0 to 1.1 km/h under normal operating conditions. The crawler assemblies are driven independently, allowing steering through differential track speed control.

One of the defining features of the SCC6300 is its extensive superlift system. The crane can utilize up to 400 tonnes of counterweight, including central ballast and superlift ballast combinations. The superlift counterweight radius can vary from 13 to 19 meters depending on the lifting arrangement. This system significantly improves moment resistance and allows the crane to perform demanding heavy industrial lifts with improved safety margins. The crane also includes a comprehensive electronic safety package incorporating load moment indicators, boom angle sensors, anti-two block systems, over-hoist protection, automatic fault diagnostics, black box recording, wind speed monitoring, and emergency stop systems.

Transport and assembly were also carefully considered in the SCC6300 design. The crane breaks down into modular transport components including crawler frames, boom inserts, jib sections, counterweight trays, hoist units, and superlift attachments. Sany incorporated self-assembly and self-disassembly capabilities, allowing the crane to erect and dismantle major components using its own hydraulic systems and auxiliary equipment. This reduces dependence on assist cranes and improves efficiency during relocation between project sites.

The SCC6300 is commonly used in refinery construction, heavy module erection, wind power projects, steel plant maintenance, and large bridge construction. Its combination of high lifting capacity, long boom systems, modular transportability, and advanced hydraulic controls positioned it as one of Sany’s flagship heavy crawler cranes during its production period.
