Cartwright unveils Insuliner trailers

UK-based trailer builder, Cartwright, has delivered four new ‘Insuliner’ trailers to Scottish freight company, Northwards, which are designed to combat salt spray.

Cartwright has said that the Insuliner has been designed to mitigate rust issues that are exacerbated by salt spray. Northwards told the manufacturer that its trailers were being continually exposed to salt spray during 14-hour ferry trips to and from the mainland.

“The trailer has been designed around a fully galvanised chassis with the headboard and rear door pillars made from the same material,” said Cartwright in a statement. “For the crossbearers (supporting the insulated floor), side rave and cant rail, Cartwright used the innovative Magnelis coated steel, which offers the best possible strength with corrosion-resistant properties that are up to ten times better than galvanising.”

Northwards Director, Neil Leslie, has said that the company has a fleet of around 120 trailers that are repeteadly exposed to salt-laden air on ferry journies between Aberdeen and the Shetland Islands, particularly in the autumn and winter months.

“The problem of salt was affecting the build integrity of our trailers, particularly corrosion on the front bulkheads,” said Leslie.

“The bespoke trailer is also fully ENXL compliant giving maximum load security for uniform loads without the need for additional strapping and also features a twin pelmet and heavily insulated curtain to ensure the best possible temperature control in the trailer.

“We are excited by the quality and specification of the new Insuliner from Cartwright.

“We are primarily serving the island communities in Orkney and Shetland and the freight is very varied. With a range of industries from Aquaculture to Oil & Gas it is a mixture of all types of goods for customers large and small to service the community on the islands and keep their economies going.

“These Insuliners will be used to export fresh salmon from the islands with the versatility of being able to load a variety of different cargoes for the return journey by having the flexibility to load/unload through the side rather than being restricted to the opening area of the rear doors on a standard fridge trailer,” he said.
