Danish Army
Specific: Delivered as part of
the MDAP
1951/55. A total of 28 vehicles were delivered with the
standard M9 trailer. Intentionally use in Denmark was
artillery-tractor, but because of lack of all-wheel-drive
the M20, coupled to a 55 ton Blumhardt trailer, was used
as prime-mover for the Centurion.
Both soft- and hard-top version were used.
The Diamond were replaced by Magirus-Deutz
270D34AS from 1971
onwards.
Historical: Produced to a British specification
drawn in 1940, due to the fact that no British
manufacturer was able to produce tank transporters in the
quantity needed.
In conjunction with the Washington-based British
Purchasing Commission Diamond T took a heavy-duty truck
chassis and from it, developed a diesel-engined ballast
tractor which, coupled to a multi-wheeled draw-bar
trailer was capable of hauling 40 to 45 tons.
A prototype was ready for approval in September 1941,
although production had taken place since mid 1941.
Its main use was evacuation form points along the axis of
evacuation and supply. Its use in battlefield recovery
was limited because it was not designed for travel over
rough and muddy terrain.
The rear body consisted of a large, flat-sided box which
was designed to carry up to 6.750 kg (15.000 lb.) in
cast-iron weights to provide sufficient traction for the
rear wheels.
Produced with open cab and folding windscreen from august
1943. Around the same time winch controls were moved
outside the cab and placed alongside the winch itself.
Adopted in the US Army as "substitute standard"
and with the introduction of the M26 "Dragon
Wagon" downgraded to "limited standard" in
June 1943.
More than 6.500 produced from 1941 until 1945, some under
a subcontract by FWD.
The standard trailer was a 40 ton drawbar unit known as
M9 and produced by Checker Cab, Cranes, Dyson, Fruehauf,
Pionter-Williamette, Rogers and Winter-Weiss.
During the 1950´s many of the British Diamonds were
re-powered with a Rolls-Royce C6NFL-134 12.1 liter
petrol-engine.
