Unic URW706C Load Chart PDF + Specifications

The Unic URW-706C is a high-performance spider crane engineered to deliver strong lifting capability while maintaining the compact footprint necessary for operation in restricted environments. As part of Unic’s larger mini crane series, the URW-706C is capable of lifting up to 6,000 kg, positioning it among the most powerful spider cranes in its class. The crane utilizes a six-section hydraulically telescopic boom that extends from approximately 5.9 m to 19.5 m, allowing operators to perform lifting tasks at significant heights while maintaining precision and stability.

To further extend its working range, the crane can be equipped with a hydraulically luffing fly jib. This attachment increases the crane’s maximum lifting height to approximately 26–27 m, depending on configuration, while also improving reach over obstacles such as building structures or rooftops. The fly jib typically provides lifting capacities up to around 1.5 tonnes, enabling the crane to handle lighter loads at greater heights and radii.

The URW-706C is mounted on a crawler chassis, providing excellent traction and maneuverability across uneven terrain and confined worksites. The crawler design allows the crane to access interior building spaces, rooftops, and narrow construction areas where wheeled cranes would not be practical. The machine can also perform pick-and-carry operations at low speed, enabling loads to be repositioned within a jobsite without repeatedly setting up the outriggers.

Stability during lifting operations is achieved through a four-outrigger spider configuration. The outriggers can be deployed in multiple positions to adapt to different site conditions, allowing the crane to operate even when space restrictions prevent full extension. This flexibility enables safe lifting in tight urban construction environments, atriums, factories, and other complex job locations.

The lifting system is powered by hydraulic winches designed for smooth and precise load handling. The crane typically features both main and auxiliary hoists, providing flexibility when switching between heavy lifts and lighter precision work. The slewing system allows continuous rotation of the superstructure, enabling operators to position loads efficiently without needing to reposition the entire crane.

Power for the URW-706C is provided by a diesel engine mounted within the compact chassis, delivering reliable hydraulic performance for lifting, slewing, and boom operations. Some configurations are available with electric power options to allow indoor or emission-restricted operation, expanding the crane’s usability in modern construction environments.

Operator control is performed through a radio remote control system, allowing the operator to maintain a clear view of the load while controlling crane movements from a safe location. This improves both safety and accuracy during lifting operations. The crane’s control system includes load monitoring and safety features designed to prevent overload conditions and ensure safe working limits are maintained.

The compact dimensions of the URW-706C are a key advantage. The crane is designed to pass through narrow access points and operate in confined areas while still delivering strong lifting performance. This combination of compact design and high lifting capacity makes the machine particularly suitable for glass installation, façade construction, steel erection, and industrial plant maintenance.

Overall, the Unic URW-706C represents a balance between lifting power, compactness, and operational flexibility. Its telescopic boom, optional fly jib, crawler mobility, and advanced remote control system make it a versatile lifting solution for projects where access limitations and precision lifting requirements are critical.
