Quick-assembly crane

How does a quick-erecting crane work?

The principle of automated unfolding (GMA)

Everything hinges on a well-designed mechanism. Gone are the long and tedious assembly of traditional models; we're talking about a Self-Erecting Crane (SEC). Its mast, articulated or telescopic, erects itself thanks to a system of hydraulic cylinders and cables. The crane operator controls the entire system from the ground using a remote control. This represents a huge safety improvement, as no technician needs to climb to heights during installation. In just a few hours, the boom is locked in place. You're ready to lift your first loads.

Transport and ballasting: the example of the Terex CBR and CSE ranges

The real strength of this equipment lies in its mobility. The structure folds completely onto an axle to form a compact unit, easily transported with a standard truck. Once on site, precise leveling is essential. The Terex CBR and CSE ranges are excellent examples of this efficiency. They feature very simple mechanisms for positioning the ballast blocks at the base. This guarantees exceptional stability against wind and heavy loads. Another advantage is their small footprint, allowing them to easily navigate dense urban centers or confined spaces.

The ideal construction sites for this type of crane

Detached houses and small apartment buildings

Builders of houses or small apartment buildings love using a GMR (. On these sites where space is always limited for storing materials, the machine centralizes all handling. Its reach easily covers the entire building. No more endless trips with ground-based equipment. Masons save a tremendous amount of time pouring concrete or laying floors. The pace increases, and above all, physical fatigue is significantly reduced.

The development of small local infrastructures

These systems aren't limited to housing. They're ideal for urban renewal or the creation of small-scale infrastructure. Whether you're building a single-story school, developing a local station, or restoring a historic rooftop, the compact base allows for installation close to the work site. Furthermore, the discreet assembly significantly reduces noise pollution for neighbors—a compelling advantage for securing public contracts in urban areas.

Fast-erecting crane vs. conventional tower crane: making the right choice

GMA: autonomy and short-term agility

The choice of equipment often determines the overall profitability of a project. The automated version stands out for its high degree of independence. True to its name, it assembles itself. By eliminating the rental costs of support equipment, you significantly reduce the installation budget. It's the ideal solution for projects lasting from a few weeks to a few months. Here, flexibility is prioritized over extreme heights.

The GME, reserved for large-scale projects

The modular assembly crane (MIT) is designed for massive and lengthy construction projects. Its installation requires significant logistical planning. Several trucks are needed to deliver the mast and jib sections, not to mention the giant mobile crane required for assembly. If your project involves dizzying heights or colossal loads, you will need to opt for a conventional tower crane. These are built to withstand the enormous stresses of large structures or very tall buildings.

Buy or rent a self-erecting crane

The advantages of buying your own crane

Having this equipment in your own fleet is a real winning strategy for general construction companies. The market for quick-assembly cranes is full of excellent opportunities, especially in the used market. To give you an idea, buying a refurbished, second-hand quick-assembly crane will cost you around €40,000. This is an investment that pays for itself over several years and guarantees you always have a machine available. You can also consult our catalog to see our currently available used models
