HC-L cranes. Technology for the future.

The HC-L series with level luffing. The HC-L series of luffing jib cranes developed by Liebherr-Werk Biberach GmbH sets new standards. The latest HC-L generation features pioneering technology with level luffing for a horizontal load path. Programmable logic controller (PLC) enables a luffing jib crane to perform a horizontal load movement similar to that of a top-slewing crane with a trolley jib. Horizontal load movement. Horizontal load movement is a genuine innovation on the Liebherr HC-L series of luffing jib cranes. During jib movements the control unit automatically adjusts the hoist gear...

1Level luffing. Intelligent control. Programmable logic controller (PLC) allows a luffing jib crane to perform a horizontal load movement similar to that of a top-slewing crane with a trolley jib. This is an entirely new overall technological concept. During jib movements the new control unit automatically resets the hoist gear so that the hook moves horizontally – a crucial advantage for assembly and concreting tasks. Precise load movement. The level luffing function can be switched on or off by the crane operator as required. Simultaneous operation of the jib and hoist gear is also possible...

2High handling capacity. High-performance drives. Liebherr luffing jib cranes are equipped with high-performance drives that guarantee maximum handling capacities and boost profitability. HC-L cranes are equipped with the very latest Liebherr-built hoist, luffing and slewing gear drives. All cranes with a level luffing function are fitted with infinitely variable frequency-controlled drives. FC hoist and luffing gear. Liebherr offers a wide range of high-performance drives, with the ideal rated output available for any application. Their principal benefits include automatic load moment monitoring,...

Practical details. Easy-assembly transport units. HC-L cranes employ a modular system for assembly in real-life situations. The slewing platform can be broken down into separate parts, each of them easy to erect. The cab platform with the crane cab can be bolted on or detached separately. Easily accessible drives. All drives are easily accessible for servicing tasks on a machine platform of generous size. A large number of plug-type electrical connections is provided for rapid crane assembly. Control and monitoring system. These cranes are supplied as standard with the electronic monitoring system...

The IC tower system. Climbing inside buildings. The Internal Climbing (IC) tower system was developed specifically for lift shafts of limited size. The tower has overall dimensions of just 1.9 m x 1.9 m and is therefore suitable for the narrowest of lift shafts. To save space and to protect the assembly, the entire climbing hydraulics are located inside the tower section, with everything designed to keep the tower’s external dimensions as low as possible. Particular attention has also been paid to easy handling of the guide frames. Special tower sections are used at the clamping points. The tower...
