Diamond 4-Ton 6×6 Truck T975 for Boat Bridge Erection, Trailer, 2 Wheel, Utility and Boat Bridge Erection 27 ft.
Very rare and impressive unit designed and used in the Korean War!
This combination is basically an upgraded Diamond 4 Ton 6×6 Truck T975 long wheelbase (produced in 1945) which has been executed in the fifties for the specific purpose to transport a Bridge erection boat. It is featuring an open cab, winch and comes with many small details.
The unit is an older restoration. Truck and trailer will be delivered in as-is condition but running conditon. The original fuel system is currently not in use, vehicle runs on a separate fuel tank bypassing the original fuel tank.
Will come with Dutch road licence.
The Boat for Bridge Erection (27 ft) is only externally restored.
Boat is basically complete, both engines are still installed but need a full maintenance / restoration.
It is a very nice and complete unit and therefore a very impressive combination and a great buy for the serious collector. This is most probably the only surviving example in this condition!

Diamond 4 Ton 6×6 Truck T975
In 1939-1941 the Army Ordnance Corps was developing a complete line of tactical trucks that could operate over all roads and cross-country terrain in all weather.
4-ton (3,600 kg) load rated six-wheel drive trucks had been successful towing artillery in the 1930s, the size would be standardized to tow the new 155 mm howitzer M1.
Autocar, Diamond T, and White were building prototypes; Diamond T built 1,000 Model 967s in 1940.
In 1941 their improved Model 968 was standardized and went into production at their Chicago plant. They would build over 30,000 chassis between 1940 and 1945.
Developed for the Artillery Branch, the chassis also became the standard medium wrecker and was used by the Corps of Engineers for cargo, dump, and specialty bodies.
A crane for chemical weapons and an extra-long cargo version for Canada were also built.
In addition to trucks built for Canada 2,245 were exported under the Lend-Lease Act, most to the British, French, and Canadians.
This specific truck is after the war modified as boat bridge erection transporting unit. A very impressive unit and almost impossible to find these days!
Trailer, 2 Wheel, Utility, Pole Type
The Trailer, 2 Wheel, Utility, Pole Type, 2 ½ Ton Model D-2540-S is built by Electric Wheel Co. from Quincy USA. The company founded in 1890 build in the early day’s wheels for farm implements, wagons, and other equipment.
In 1916 they start to construct tractors for agricultural purposes. One of their first models was a Light Allwork tractor powered by a four-cylinder engine with a 5-inch bore and 6-inch stroke – also designed by the company. The Allwork weighed 4,800 pounds and provided 27 to 30 hp on the belt and 12 to 15 hp at the drawbar. The tractor used a two-speed transmission and burned kerosene fuel.
Later many models followed in the same range.
In 1927, the Electric Wheel Co. expanded its line and produced the huge EWC 80 crawler tractor. It came with a Waukesha 6 ¾-inch bore by 8-inch stroke engine that put out 110 hp at 800 rpm. Consequently, the crawler carried a 60-gallon fuel tank to feed that big, thirsty engine. The company also built a smaller version, known as the EWC 5-ton crawler, that same year.
The Electric Wheel Co. quit the tractor business entirely by 1930, likely because of the Great Depression, but continued to make wheels and wagons until 1957. This trailer is built by the company for the US Army corps of Engineers in February 1951
Boat Bridge Erection
The first of these boats were produced in 1951 and have been in production for about 20 years thereafter. The first boats were equipped with 2 Gray Marine petrol engines. Later the boats were built with 2 Detroit Diesel engines and several old petrol boats were also equipped with this.
The boats were made for the US Army Corps of Engineers who used these boats for building pontoon bridges and for transporting cargo.
The boat is divisible into 2 parts, making transport on smaller trucks easier.
Famous places where these boats have served for the US Army are; America, South Korea, Vietnam, and Germany. In America, these types of boats have also been on standby to help in the event of an oil spill by the Marine Spill Response Corporation (MSRC).
Between 1981 and 1983 these boats were phased out by the US Army in Germany. Many these boats were then sold (most of them to a buyer in the Netherlands) or scrapped. Below a picture of a similar boat on exercises in Germany in the late seventies

Finish Collector, Director of Camp Degerö, Major (Rtd.) of the Finish Army a.o..
This combination is very rare and impressive. However, it is basically a post war vehicle it fantastically fits in the collection dedicated to the Korean or Vietnam War period.
This combination is most probably currently the only available on the market.
It’s a very rare and unique set used as well by the US forces and many European nations.
Therefore, it is a good investment for a serious collector
