Crawler crane-SCC750A-5

Product catalog summary

Main Characteristics
The SCC750A-5 is a crawler crane with a lifting capacity of 75 tons. It features a maximum lifting moment of 300 t·m, a boom length of up to 57 meters, and a fixed jib combination of 45m+18m. The crane is powered by an ISUZU 6HK1 diesel engine, compliant with Chinese Off-highway Tier III Emission Standards, offering a rated power of 212 kW at 2000 rpm.

Engine and Electrical Control System
The engine is a 4-stroke, water-cooled, 6-cylinder vertical in-line with a displacement of 7.79L. The electrical control system includes a self-developed SYIC-II integrated control system, featuring a CAN BUS for data communication and optional remote control capabilities.

Hoist Mechanisms
The main and auxiliary load hoist mechanisms are driven by separate motors via gearboxes, with a drum diameter of 520mm and a rope speed of up to 135m/min. The boom hoist mechanism features a drum diameter of 355mm and a rope speed of up to 96m/min.

Hydraulic System
The hydraulic system includes open variable displacement piston pumps, a dual gear pump, and a heat exchanger for cooling. The system operates at a maximum pressure of 33 MPa.

Cab and Control
The cab is ergonomically designed with an integrated touch screen and monitoring display. It includes adjustable seating, air conditioning, and monitoring cameras.

Safety Devices
The crane is equipped with numerous safety devices, including an emergency stop, load moment indicator (LMI), over-hoist and over-release protection, function lock, boom hoist drum lock, and slewing lock. Additional features include a tri-color load indicator, alarm lights, and a monitoring system for remote diagnostics.

Technical Parameters
The crane's major performance specifications include a maximum rated lifting capacity of 75 tons, a boom length range of 12 to 57 meters, and a swing speed of up to 2.5 rpm. The transport weight of the basic machine with crawler frames and boom base is 36.5 tons.

Configurations
The SCC750A-5 offers H and FJ configurations, with options for crawler extension and retraction, and a variety of hook blocks ranging from 9t to 75t.

Specifications

Transport Dimensions: The crane's transport dimensions vary based on the configuration, with the basic machine (with boom) measuring 12.50m in length, 3.20m in width, and 3.45m in height, weighing 36.5 tons.
Ground Pressure: The average ground pressure with the basic boom is 0.077 MPa.
Gradeability: The crane can handle a gradeability of up to 30%.

Components and Weights

Various components such as boom inserts, jib bases, and counterweight blocks are detailed with their respective dimensions and weights. For example, a 9m boom insert weighs 0.87 tons, and a left counterweight block I weighs 3.6 tons.

Configurations

H Configuration: This includes a boom length ranging from 12m to 57m, with specific load capacities at different boom lengths and radii.
FJ Configuration: This involves a combination of boom and jib, with the longest boom and jib combination being 45m + 18m. Load charts are provided for various jib lengths and boom-to-jib angles.

Load Charts

Detailed load charts are provided for both H and FJ configurations, indicating the rated capacities at different boom lengths and working radii. Notes specify that the actual rated capacity is adjusted for the weight of lifting tools and that the crane must be on firm, level ground for accurate load handling.

Additional Information

The document includes a disclaimer that technical parameters and configurations are subject to change without notice due to updated technology.
