A workhorse flatbed for plant hire firms, groundworkers and landscapers moving mini-diggers, pallets and fencing. The payload relative to its own weight is the reason it is so common on sites: 675kg unladen against a 3,500kg gross leaves a genuinely useful figure.
A tri-axle LM126T is also offered.
