New intelligent cab suspension for forwarders from Komatsu Forest

The Komatsu Comfort Ride cab improves operator comfort by reducing vibration and jolts.

The underlying construction of the new cab consists of two frames, one on top of the other. There are hydraulic cylinders between the frames that are fitted with integrated remote position sensors to keep the cab in the centre position. This creates a four-point suspension that allows long and free movements in the suspension. The cylinders long travel allows the suspension to absorb more energy, reducing the chance of the cylinder bottoming out.

The large support area created by the four-point suspension also provides good damping, which results in gentler rocking movements compared to a three-point suspension. A hydraulic stabiliser prevents the cab from excessive side to side rolling. A Ride Height Control function compensates movements so that the cab is always in the centre of the cylinders regardless of any shift in the centre of gravity of the cab.

The operator can press a button to raise the cab to the cylinders highest position. This helps when unloading the forwarder as a much better view of the bunk is achieved. The Komatsu Comfort Ride will be introduced in 2013 as an option on all Komatsu forwarder models. Source: www.komatsuforest.com
