Maritime Transport has bought from Mercedes-Benz for the first time in five years, with an order for 65 Actros tractor units.
Mercedes has already begun delivering the vehicles, which have BigSpace cabs, to the haulier.
The deal comes just days after Maritime announced its purchase of 30 Volvo FHs.
Group financial director Alan McNicol said the company was “delighted to rekindle [its] association with Mercedes-Benz after five years”.
He said: “These tractors are a great addition to our fleet and I know our drivers are going to be delighted with their nearly 6,000 litres of internal capacity.”
Truck fleet sales manager at Orwell Truck and Van, Rob Dale, said: “We are extremely happy to supply Maritime with these trucks, reigniting what has historically been a great working relationship with the company.
“We are very proud of this model which boasts 449hp and have no doubt it will look fantastic in the iconic Maritime livery.”
Maritime also recently bought 100 new Lawrence David trailers and 200 skeletal sliding trailers from Dennison.
