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 so that the hook moves horizontally. This is a cru-cial advantage for assembly and concreting work. The new technology simplifies the crane operator’s job and makes the construction site safer and more efficient.

High handling capacity.Infinitely variable high-performance drives from Liebherr achieve significantly higher load handling capacities. Lieb-herr’s modular crane program offers the

best drive for every application. These intelligent drive systems, manufactured by Liebherr in-house, have a high level of functional reliability and un-compromising performance. Their low energy consump-tion has a positive effect on operating costs. Straightfor-ward changeover from single- to double-reeved hook operation ensures optimal handling performance.

Practical details.HC-L cranes are designed for straight-forward assembly. Even on confined building sites, they are particularly easy to erect. Practical assembly in real-life

situations was a top priority at the design stage. The slewing platform can be taken apart into transportation elements that can be handled by a mobile crane – a crucial advantage if the crane is to be dismantled at a great height.

Climbing inside buildings.Luffing jib cranes from Liebherr are ideal climbing cranes for use inside buildings. The Internal Climbing (IC)

tower system has been developed specifically for these applications. For rapid-rise projects, IC towers can be erected in lift shafts or the smallest of niches. These climbing tow-ers are also secured to buildings externally. Luffing jib cranes are being used to an increasing extent on high-rise construction projects.

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.

1Level luffing.

Intelligent control.Programmable logic controller (PLC) allows a luffing jib crane to perform a horizontal load movement simi-lar 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 automat-ically 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 at any time, for optimal efficiency and to suit con-struction-site requirements.

This new technology makes crucial time savings possible and greatly simplifies the crane operator’s task. Setting down loads with a high level of ac-curacy and precisely where required is also signifi-cantly easier. This greatly facilitates load handling, in particular on confined building sites.

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, travel at micro speeds, use of the full extent of joystick travel and load holding without engagement of the hoist gear brake.

FC slewing gear.The new FC slewing gear drive enables the crane to be slewed at micro speeds without jerks or jolts, and also detects and suppresses wind and load influences. The control unit matches slewing gear drive torque automatically to the jib position. The integrated anti-sway function identifies and prevents crane vibration and load swing.

Greater hook heights.For greater hook heights the new 3-speed FC hoist gear, for instance, is rated at 110 kW. Hook

heights of up to 625 m are available for single-reeved working. With this crane specification, the hook moves at up to 240 m/min, thereby ensuring exceptional efficiency on very high-rise

building projects. Rapid re-reeving.

Straightforward re-reeving of the hook from single- to double-reeved operation allows HC-L cranes to be adapted efficiently and quickly to construction site conditions and maintains their high handling performance. A version for single-reeved hook opera-

tion only is available as an option.

Separate slewing platform elements for assembly and dismantling at great heights.

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 sepa-rate 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 (EMS), the load moment limitation system (LMB), the working range limiting system (ABB) and the ma-chine data logging system (MDE). On request, HC-L cranes can be equipped with additional electronic components such as the anti-collision system (AKS), remote data transmission (DFÜ) and a machine data evaluation system (MDA).

Pre-installed plug connections for rapid start-up.

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 sec-tions need no additional reinforcement.

When dismantling the cranes in high-rise buildings, the add-on compo-nents of the climbing section can easily be removed as a weight reduc-tion measure.

Climbing outside buildings.The IC tower system can also be used for climbing outside buildings. The rigid tower sections provide high hook heights and need only a small number of anchorages to the building.

This tower system is also suitable for trolley jib cranes.
