Self-Erecting Crane (GMR) The Self-Erecting Crane (GMR), or Self-Erecting Crane (GMA), is a tower crane that is erected autonomously by a mechanical or hydraulic process. The commissioning of this type of crane is thus much simpler than that of part-erecting cranes (GME) which are assembled by a mobile crane.
Quick-erecting cranes are ideal for short-term jobs, as they can be easily set up, dismantled and transported. Most of the CMGs are indeed radio controlled by a single operator. They are particularly suitable for working on small buildings at a medium height, or in tight spaces.
The boom of the quick-erect crane can be horizontal or slightly raised to gain height. Horizontally, the tip can be folded back to avoid hitting surrounding buildings.
