One of the questions asked a lot is whether or not the concept is fully compatible with all types of machines. Although most 1.5 tonne excavators are almost identical in their design there are can be slight differences in the undercarriages. This is of most concern to us because we need to ensure the machine is able to fully track to the front of the cowls without anything catching or preventing this to happen.
Another adaption to the cowls is the overall shape in them. In the past we always worked under the assumption that the majority of machines had expanding tracks. This meant the machine could get into position and then expand its tacks to sit flush against the side of the trailer. However, not all machines have expanding to tracks and to account for this the cowls have been had a slight redesign to ensure there is no lateral movement regardless of whether the tracks are expanded or not.
We have tried the most popular machines and will always arrange a demo with a machine we haven’t tested it on to be positive that it fits securely. In the pictures shown below the trailers are carrying a Kubota KX016-4, Takeuchi 216 and JCB 801 cabbed. Scottish Southern Electric recently purchased a number of Digadoc trailers from Brian James Trailers to use with their JCB 801 cabbed machines. The benefits of this concept are even more prevalent in relation to cabbed machines because these are even more difficult to secure properly due to the fact that ratchet straps have to work around the closed cab of the machine.
