For clients who value streamlined operations, these cranes ensure minimal downtime and reduced labor requirements. Their compact transport dimensions and modular LiTRAX axle system facilitate easy movement to and from the site, making the K Series an excellent choice for urban areas and constrained spaces.
Liebherr 42 K.1: The Compact Powerhouse for Urban Construction
The 42 K.1 represents the entry point to the K Series lineup, yet it delivers impressive lifting capabilities and reach that exceed its size. This model is particularly suitable for residential and small-scale commercial projects where space is limited, but reliability and power are paramount.
Key Specifications:
- Maximum Hook Height: 28.0 meters
- Maximum Lifting Capacity: 4,000 kg
- Maximum Radius: 36.0 meters
- Lifting Capacity at Maximum Radius: 1,200 kg
Features:
The 42 K.1 is engineered for projects needing compact yet powerful lifting solutions. Designed for quick setup and takedown, it’s ideal for projects requiring equipment to be relocated frequently. Adjustable jib lengths and multiple hook heights enable this crane to cater to varying project needs, adapting easily to different site conditions.
Use Case: Multi-Story Residential Projects in Densely Populated Areas
For multi-story residential builds in urban environments, the 42 K.1 offers an efficient solution that requires minimal space. For example, in a recent project within a tightly-packed city center, the crane’s compact design enabled it to be positioned close to the building, efficiently lifting materials up to the desired height while occupying a minimal footprint.
The 42 K.1’s swift assembly allowed the project to commence immediately upon crane arrival, enabling construction crews to stick to a tight schedule. Its robust construction and smooth operation provided the necessary power to lift and position heavy materials, all while navigating narrow city blocks and reducing noise, which is a crucial factor in residential areas.
Liebherr 65 K.1: The Versatile Performer with Expanded Reach and Power
The 65 K.1 is a step up from the 42 K.1, featuring extended reach and an enhanced lifting capacity suited for a broader array of construction applications. Its design accommodates commercial projects that demand higher capacity and flexibility.
Key Specifications:
- Maximum Hook Height: 34.6 meters
- Maximum Lifting Capacity: 4,500 kg
- Maximum Radius: 43.0 meters
- Lifting Capacity at Maximum Radius: 1,350 kg
Features:
The 65 K.1 combines power with versatility, allowing operators to adjust jib lengths and hook heights according to project requirements. This crane also includes the Load Plus function, which temporarily increases the crane’s lifting capacity by reducing hoist speed. The Load Plus feature is ideal for jobs where heavier loads are required at certain stages of construction.
Use Case: Mid-Rise Office Buildings and Retail Developments
The 65 K.1 has been instrumental in numerous commercial projects, such as the construction of mid-rise office buildings and retail centers. During one recent project, a retail building required a crane capable of lifting steel beams and prefabricated materials up to 43 meters. The 65 K.1’s adjustable reach allowed it to position components precisely without repositioning, ensuring a seamless workflow and reducing setup adjustments.
Moreover, the crane’s adaptable features enabled it to work around existing structures, even on a crowded site. This versatility allowed the project team to operate efficiently without compromising safety or project timelines.
Liebherr 81 K.1: The High-Capacity Crane for Industrial Applications
The 81 K.1 is a robust model in the Liebherr K Series cranes, boasting impressive lifting power and an extended reach that meets the demands of industrial construction projects. Equipped with high-performance systems like SPEED2LIFT and MICROMOVE, the 81 K.1 is ideal for projects that require both heavy lifting and precision placement.
Key Specifications:
- Maximum Hook Height: 40.4 meters
- Maximum Lifting Capacity: 6,000 kg
- Maximum Radius: 48.0 meters
- Lifting Capacity at Maximum Radius: 1,350 kg
Features:
The 81 K.1 shines in situations requiring high lifting capacities. Its SPEED2LIFT system optimizes hoisting speed, while MICROMOVE allows for precise positioning of loads, which is crucial for heavy or delicate items. This crane’s design also includes advanced safety features, ensuring both operator and on-site safety.
Use Case: Large Industrial Facilities and Manufacturing Plants
In a recent project involving the construction of a manufacturing facility, the 81 K.1 played an essential role in moving large prefabricated wall sections and placing machinery components. The crane’s substantial lifting capacity allowed it to handle heavy loads without compromising stability or control, significantly aiding in the installation of high-capacity equipment.
The 81 K.1’s reach enabled it to access all areas of the construction site, and its MICROMOVE system allowed precise positioning of machinery parts, enhancing operational efficiency and ensuring that each component was accurately installed on the first attempt. This minimized rework and maintained project momentum, an invaluable benefit in industrial construction.
Liebherr 125 K: The Heavy-Duty Crane for Large-Scale Civil Engineering Projects
The 125 K is the largest crane in the Liebherr K Series cranes, designed for high-capacity lifting and extended reach. This crane is perfectly suited for large-scale infrastructure and civil engineering projects, such as bridge construction or highway overpasses, where maximum lifting power and stability are critical.
Key Specifications:
- Maximum Hook Height: 41.5 meters
- Maximum Lifting Capacity: 8,000 kg
- Maximum Radius: 55.0 meters
- Lifting Capacity at Maximum Radius: 1,300 kg
Features:
The 125 K crane is equipped with advanced features that provide adaptability, including a 30° luffed jib position and a 45° obstacle-avoidance position. These configurations offer operators exceptional flexibility, allowing them to avoid obstacles and position loads with precision. The crane’s stability and strength make it a trusted tool for projects requiring high safety and reliability standards.
Use Case: Bridge and Highway Construction
The 125 K’s extended reach and heavy-duty lifting capabilities were recently put to the test during a highway overpass construction project. This crane was crucial in lifting heavy concrete segments and positioning them accurately across the bridge span. The 125 K’s impressive reach ensured that materials could be moved and installed without relocating the crane multiple times, saving valuable project time and resources.
In another instance, the 125 K was deployed to lift steel bridge girders. Its advanced positioning features allowed for exact placement, ensuring that the girders were secured with precision and stability.
