Buy or hire the GH Plant with DigaDoc if...
Bought by plant hire and groundworks firms that need to prove what left the yard and where it went, since DigaDoc records load movements electronically on top of the standard GH plant trailer chassis. It is the same GH94 base trailer as the plain GH94, with the tracking hardware added.
