The Bedford QLD was the Bedford QL series general transport truck manufactured by Bedford for British forces during World War II .

History 

The Bedford QL was built from 1941 to 1945. Approximately 52,250 vehicles of this type were manufactured in total. The QLD was the most commonly built version of the series.

QL1: orignal Prototype.

QLB: Bofors gun tractor. Approximately 5,500 QLBs were built.

Several QLBs were fitted with shortened GS bodies and recovery cranes to be used as wreckers by the Danish Army (Used until late 1960s).

QLC: Fire engine,Signals vehicle,Petrol tanker.

QLD: General service cargo truck and was the most numerous version in the series.

QLR: Signals vehicle. Originally mounted on the QLC chassis/cab, special QLR chassis were soon put into production, which differed from the standard type in having special electrical equipment, radio suppression, fitment of a 660 W auxiliary generator driven by the transfer case power-take-off and, like the QLT, two 16 gallon petrol tanks instead of one behind the cab. The interior furniture, partitioning and radio equipment varied from the different functions. On vehicles installed for the wireless role, a tent could be erected at the rear. Between cab and man body were lockers for aerial masts and other equipment. Beneath the body were further lockers and racks for cable drums, batteries, tyre chains, 20 gallon drinking water tank, rectifier box, tools, fuel tank for the auxiliary engine, jerrycans and other items. The basic body shells were produced by Duple, Lagonda, Mulliner, Tickford and others. A revised body was introduced in during 1944 for the Command High and Low Power and Wireless High Power roles. This body had an improved "L"-shaped tent which could be erected alongside the left-hand side and rear of the body.

QLT:Troop carrier. From August 1941 and until the end of WW II more than 3,300 QLTs were produced.

QLW :Air portable tipper.
