Swing loader
The swing loader is a variant of the wheel loader . In contrast to a conventional wheel loader, the shovel arm of the swing loader is attached to the front of the vehicle on a turntable and can therefore be swiveled by up to 180 ° (2 × 90 °).
The aim of this construction is to enable a higher tipping load in the pivoted state than when working from the front. However, this is only possible if the device is equipped with a rigid frame and four-wheel steering, as otherwise the center of gravity of the device is too far away from the center when it is pivoted. In order to increase the stability of the device even further, some manufacturers use load-dependent axle supports and swivel chair weights in their swivel loaders. However, there are also swing loaders with articulated steering.
The swiveling shovel arm enables the machine operator to work in one lane, which is particularly beneficial due to the short travel distances, low floor load and minimal traffic obstruction. Another advantage of the swing loader is the versatility of different work tools such as backhoe buckets , grabs or crane arms. This universality led to the fact that swing loaders are often used as pioneer devices in the military.
In 1949, the first European swing loader was developed in Italy by the brothers Carlo and Mario Bruneri, but it can be classified more as an excavator. In 1952, Ahlmann built the first German swing loader.
