New-generation crane girder revolutionises load handling in SA

Demag’s innovative crane girder

Demag’s newly-launched V-Type crane girder can easily manage more than 500 000 load changes.

The Demag’s V-Type girder, which was launched in early 2016, delivers safety and impressive load handling rates. Regardless of the model type selected – the V-Type girder can be adapted to any building shape, and is the ideal solution both for existing buildings, as well as for new construction projects.

The following Demag V-Type girders are available:

Type 1: The ends of the standard crane girder slope at a 45° angle. The bottom edge of the girder is at the same level as the crane runway, offering sufficient space for loads such as pipes.

Type 2: On the compact version, the bottom edge of the V-Type crane is significantly lower than the crane runway. This variant is particularly suitable for projects that offer limited space.

Type 4: The lower edge of the slightly raised crane girder is located higher than the crane runway, which offers a gain in lifting height, making it suited to applications with considerable space.

Type 5: The girder is significantly raised. Its lower edge is located above the crane runway, which provides for a large range of lifting heights.

Type 6: Types 1 and 2. These can be adapted to suit the available space, since the dimensions above and below the crane rail can be freely selected. The bottom edge of the crane girder is below the level of the crane runway.

Built with safety in mind, the V-Type girder allows 30 per cent more light to pass through, enabling personnel to better see their surroundings, while brightening the workspace. This improved view ultimately results in a safer and more attractive working environment. The V-Type girder also has a shorter time cycle, helping to increase productivity and overall output. It boasts several lifting points for safer installation of the load and has more clamping and attachment points for lamps.

The tapered diaphragm joints also replace the solid box-section design of conventional cranes. On average, the V-Type crane is 17 per cent lighter than comparable cranes that have box-section girders. This not only reduces the forces transmitted to the existing support superstructure and provides architects with greater freedom when planning new building layouts, but also improves the relative deadweight-to-load-capacity ratio.
