Special multi-axle vehicles, ro-ro tractors, terminal tractors and special equipment - the profile of the Dutch company Terberg.
Its history began in 1948 with a tiny workshop for the repair of military equipment left in Europe after the WW2.
When in the late 1970s and early 1980s, multi-ton ferry transportation by sea and the term RO-RO appeared, special port equipment was required, which was among the first to be developed by the family firm Terberg.
The company was not only at the origins of the manufacture of special port tractors and tractors, but is still the largest manufacturer of this kind of equipment in Europe: it produces up to a hundred trucks and about 600 terminal tractors per year, of which most of them are ro-ro tractors. ...
The company's port products can be divided into two large groups: RO-RO tractors (RT series) and terminal (YT series - formerly TT). In turn, each of these groups is subdivided into a pair of subgroups according to the total mass of road trains - ro-ro tractors can have a carrying capacity of either 120 tons or 230 tons, and all are all-wheel drive.
Terminal tractors have only rear-wheel drive (i.e. 4x2 wheel arrangement) and are divided into two groups according to the height of the fifth wheel from the roadway - 921 and 938 mm with a total weight of up to 80 tons.
True, this slender classification was violated by the recently appeared four-axle vehicle (8x4), which can operate both as a ro-ro tractor with a total mass of a road train of up to 350 tons, and as a terminal tractor designed to transport large containers.
It is driven by the wheels of the rear axle pair Axletech. Tractors have either a right or left cab arrangement, depending on the customer's requirements, which depends on the specific pier where the tractor will have to work in the future.
Structurally, terminal tractors differ from ro-ro tractors only slightly. The old cab has a side entrance, the driver sits in only one position - in the direction of travel. Engines and gearboxes are of the same firms, but the front axles are supplied by Volvo.
