Liebherr Tower Cranes and components

We select fast-erecting and top-slewing tower cranes, drives and equipment. Configuration is coordinated with the load chart, working area and construction project.

K fast-erecting cranes

The current K programme lists 43 K, 61 K, 91 K and 125 K. Configuration connects hook height, jib length and site conditions. The working load chart belongs to a defined combination of crane equipment.

Compact L fast-erecting cranes

L cranes belong to the fast-erecting group. The manufacturer describes a compact arrangement for restricted sites. Transport and operating configurations are considered together with the lifting task at the project location.

EC-H High-Top and HC Heavy-Load cranes

EC-H is the High-Top group for medium and large projects. HC is identified as the heavy-load group for tasks involving large heights and radii. Lifting parameters follow the selected model and actual configuration.

Derrick DR dismantling cranes

Derrick DR is intended for dismantling tower cranes at height. Its own disassembly and removal belong to the project sequence. Equipment selection is connected to the building, placement and the components to be handled.

Selecting a crane by its load chart

A Liebherr tower crane is selected around loads, working radii and hook height together. Maximum lifting capacity does not describe the available capacity at every point along the jib. Technical comparison starts with the project task and a defined working configuration.

The specification connects the model, jib, tower system, drives and placement conditions. Interfaces with the building and surrounding working areas are considered separately.

This supports comparison of complete equipment options and defines the required components and accessories rather than selecting a crane by the largest figure in the overall programme.

Fast-erecting and top-slewing groups

Fast-erecting and top-slewing cranes represent different project arrangements. Transport configuration and deployment are central to the first group, while the modular tower and erection package are central to the second. A category name does not replace the specification of the selected version.

Procurement connects site conditions, project duration and working area. The equipment schedule distinguishes the crane from accessories and work at the location.

This defines supply boundaries and allows complete options to be compared, including installation, connections and subsequent checks, rather than comparing only carriers without their project requirements.

The modular EC-B package

EC-B Flat-Top belongs to the modular top-slewing programme. A complete package coordinates tower, jib, mechanisms and controls. Replacing one element does not automatically preserve every parameter of the installed configuration.

The technical task separates main assemblies, connections and auxiliary equipment. A replacement component is identified by its position in the machine and its relationship with neighbouring assemblies. This supports agreement on supply content and installation checks.

It also keeps a new-crane purchase distinct from a project configuration change or restoration of an individual mechanism on an existing crane, where equipment and interfaces will remain in service.

Luffing jibs and restricted sites

A luffing crane connects load position with jib geometry and working radius. An urban project considers operating area, out-of-service position and surrounding space. These conditions belong to a particular crane configuration.

The HC-L or HC-LH project separately defines jib equipment, tower system and required mechanisms. A model designation does not replace the placement assessment. Assembly procurement distinguishes load hoisting, jib movement and slewing functions.

This structure helps define a package for the actual working function and supports the checks following installation, with reference to the selected equipment rather than a general maximum rating.

EC-H and HC in major projects

EC-H High-Top and HC Heavy-Load configurations are assessed against the specific construction task. Required height, radius and load chart are connected to the tower, jib and installed mechanisms. Maximum figures from different versions do not form a single operating configuration.

Proposal comparison separately defines main components, accessories and work at the site. Replacement procurement for an existing machine follows the installed version rather than only the heavy-crane category.

This separates an individual assembly’s condition from the parameters of the full structure and supports a connected equipment schedule and subsequent check programme.

A separate dismantling-crane package

Derrick DR addresses removal of a tower crane from a high building. Selection forms part of a project sequence covering placement, component handling and later removal of the dismantling equipment itself. This is a distinct task rather than simply continued operation of the principal crane.

The specification distinguishes the machine, working equipment and required accessories. Equipment boundaries are connected to the work arrangement for the individual building.

This allows complete packages to be compared and separates procurement of mechanisms from design of the operation, which depends on the structure, installation conditions and agreed sequence.

Hoist, gearbox and drive assemblies

A hoist connects drive equipment, power transmission and the rope system. Slewing and radius-changing mechanisms belong to other functional chains. A similar assembly description therefore does not establish the same installation position or function in the crane.

Selection considers mechanism version, mounting interfaces, connections and interaction with the controls. The procurement list distinguishes a complete assembly from specified individual components.

This defines package content before installation and relates the subsequent check to the restored function, rather than treating one motor or gearbox rating as evidence of the condition of the whole connected system.

Tower-system component boundaries

Tower elements and their connections belong to a defined crane configuration. Procurement distinguishes working equipment, the erection package and project interfaces with the building. Similar appearance does not establish that two components are identical versions.

The specification connects assembly identity to its position in the selected system and the intended interfaces. Main elements and required accessories are listed separately.

This supports package checks and installation preparation while preserving the distinction between component selection, restoration of a mechanism and the project decision on placement of the complete tower crane at a particular construction site.

Controls and assistance systems

The tower-crane programme includes controls, assistance systems and the LiCAB cab. An available function belongs to a machine, equipment version and selected configuration. The overall programme does not mean every crane has the same feature set.

Procurement and diagnosis distinguish hardware devices, operating configuration and interfaces with mechanisms. A control message is compared with the crane’s actual behaviour.

This separates a component defect from a connection problem or external condition and supports a reproducible functional check, rather than using the disappearance of a message after an electronic-device change as the only evidence of restoration.

Complete crane project scope

A supply project connects the crane, selected equipment and building site. Tower elements, working configuration, connections and required accessories are considered alongside the principal machine. Package scope follows the technical task and project work arrangement.

Before proposals are compared, equipment supply, site preparation and erection activities are separated. A system and accessory schedule supports responsibility boundaries and commissioning requirements.

It defines items included in the supply, equipment retained by the operator and how the selected configuration will demonstrate readiness for the agreed function under the conditions of the individual construction project.

Logistics and installation preparation

A crane, tower elements and individual drive assemblies require different delivery and installation arrangements. Movement route, access to the assembly position and erection sequence affect project organisation.

Configuration is coordinated with equipment placement and subsequent maintenance access. The scope distinguishes transport, preparation, lifting and system connections. Responsibility is established before installation begins.

A check programme then considers the actual package and project operation. This treats supply as a completed technical configuration at the location and gives the buyer a practical review point beyond the arrival of the principal machine and separate components.

Acceptance of the selected configuration

Acceptance begins with the functions and parameters agreed for the equipment package. The principal machine, working mechanisms and required connections are checked against the technical specification. One nominal rating cannot replace a review of the complete configuration.

The programme reflects the prepared site, available conditions and applicable documentation. Its record identifies completed checks, remaining observations and actual readiness for the specified tasks.

This creates a clear handover point and starting information for maintenance and subsequent observation. The conclusion covers only the scope actually included in the agreed acceptance programme at the individual project location.
