Liebherr’s latest generation of luffing jib cranes is expanding with the introduction of the 620 HC-L, which brings together increased lifting capacity, state-of-the-art technology, and a compact design, making it ideal for cramped inner-city areas and large-scale construction projects. As the big brother of the 440 HC-L, it offers key advantages for faster construction cycles and increased efficiency.
Liebherr’s range of luffing jib cranes now extends to the 600-metre tonne segment, with the new 620 HC-L 18/36 designed to meet the demands of more challenging construction sites. With a maximum lifting capacity of 18 tonnes in one-fall operation and up to 36 tonnes in two-fall operation, along with a jib length of 65 metres, the 620 HC-L sets new standards in its class. Thanks to its innovative Load-Plus function, lifting capacity can be increased by up to 76% for specific load charts, significantly expanding its range of applications.
The 620 HC-L is compatible with the 24 HC 630 tower system, enabling it to achieve a freestanding height of up to 74.3 metres. By utilizing existing tower sections, costs are reduced while increasing site planning flexibility. This compatibility also extends to the 440 HC-L, allowing both cranes to be assembled using the same tower sections. The optimized tower design eliminates the need for complex building tie-ins, further accelerating construction timelines.
With an out-of-service position of just 12 metres and a minimal operating position of 4.1 metres, the 620 HC-L is exceptionally space-efficient, making it ideal for urban construction sites and projects with limited space. Its compact design streamlines site planning and allows multiple cranes to operate efficiently within tight conditions.
Assembly of the 620 HC-L is significantly faster, with pre-wound hoist and luffing ropes provided on the drum to reduce setup time. Transport costs are also optimized, requiring just ten transport units at full radius, including counter-ballast. The crane’s plug & play system, featuring a central switchgear cabinet and quick electrical and mechanical connections, ensures simple and time-efficient setup.
The 620 HC-L sets new performance standards, with a jib length of 65 metres and a maximum lifting capacity of up to 36 tonnes in two-fall operation. The standout Load-Plus function increases lifting capacity by up to 76%, further enhancing its versatility. Equipped with proven Liebherr drives and the latest EMS-4 control unit, the luffing jib crane also features a 12-inch display on the TC-OS platform, with a user-friendly menu structure and configuration wizard for easy and safe setup.
Additionally, the radio control system with a 3.5-inch display provides maximum flexibility for crane operators. Key functions such as Load-Plus, Micromove, and electric weathervaning are integrated, ensuring optimal convenience and safety during operation.
With its powerful performance, efficient design, and cutting-edge technology, the 620 HC-L redefines modern engineering in luffing jib cranes, offering enhanced safety, efficiency, and economy for construction projects worldwide.
