Liebherr 620 HC-L Luffing Jib Crane Redefines Lifting Power and Efficiency
Liebherr has unveiled its latest marvel in the realm of luffing jib cranes: the 620 HC-L. This new addition seamlessly blends enhanced lifting capabilities with cutting-edge technology, all within a compact design tailored for the bustling confines of urban construction sites and expansive projects alike.
Positioned as the robust successor to the 440 HC-L, the 620 HC-L promises to accelerate construction timelines and boost overall efficiency.
Elevating Standards in Lifting Capacity
Venturing into the 600-metre tonne category, the 620 HC-L 18/36 emerges as a response to the escalating demands of modern construction landscapes. It boasts a formidable maximum lifting capacity: 18 tonnes in single-fall and an impressive 36 tonnes in double-fall operations.
With a reach extending up to 65 metres, this crane redefines benchmarks in its class. A standout feature is the innovative Load-Plus function, which, for specific load charts, amplifies the lifting capacity by up to 76%, thereby broadening the crane’s versatility across diverse applications.
Towering Heights with Optimised Design
Compatibility is a cornerstone of the 620 HC-L’s design philosophy. It integrates seamlessly with the 24 HC 630 tower system, achieving a freestanding height of up to 74.3 metres.
This strategic compatibility not only curtails procurement expenses by utilising existing tower sections but also offers unparalleled flexibility in site planning. Notably, the 440 HC-L shares this tower system, enabling both models to be assembled using identical sections.
This harmonised approach eliminates the need for intricate building tie-ins, thereby expediting the construction process.
Compact Footprint for Urban Landscapes
Urban construction often grapples with spatial constraints, and the 620 HC-L rises to this challenge with aplomb.
When not in operation, it retracts to a mere 12 metres, and during active use, it maintains a minimal operating radius of just 4.1 metres. Such a compact profile renders it exceptionally suited for inner-city projects where space is at a premium.
This design not only simplifies site logistics but also facilitates the efficient operation of multiple cranes within confined areas.
Streamlined Assembly and Transport
Time is of the essence in construction, and the 620 HC-L is engineered with this principle at its core. Pre-assembled components, including hoist and luffing ropes pre-wound on drums, significantly truncate on-site setup durations.
From a logistical standpoint, the crane is a marvel of efficiency: achieving its full radius necessitates only ten transport units, inclusive of counter-ballast. The plug-and-play system, featuring a central switchgear cabinet alongside swift electrical and mechanical connections, ensures that assembly is both straightforward and swift.
Advanced Performance and Operator Convenience
Beyond its impressive lifting prowess, the 620 HC-L is a testament to modern engineering excellence.
Equipped with Liebherr’s trusted drives and the state-of-the-art EMS-4 control unit, it guarantees operations that are both safe and efficient. The TC-OS platform’s 12-inch display offers an intuitive menu and a configuration wizard, simplifying crane setup.
Moreover, the radio control, furnished with a 3.5-inch display, endows operators with maximum flexibility. Features such as Load-Plus, Micromove, and electric weathervaning are seamlessly integrated, ensuring that operations are not only convenient but also adhere to the highest safety standards.
A Testament to Engineering Excellence
In essence, the 620 HC-L epitomises Liebherr’s unwavering commitment to innovation, safety, and operational efficiency. Its amalgamation of formidable lifting capacity, compact design, and user-centric features positions it as an invaluable asset for construction professionals navigating the complexities of contemporary projects.
