KZKT-545

from Wikipedia, the free encyclopedia

The KZKT-545 ( Russian КЗКТ-545 ) is a heavy tractor from Soviet production, which was designed in the late 1960s to replace the MAZ-537 in the following decade. The four-wheel drive trucks were assembled by the Russian manufacturer Kurganski Sawod Koljosnych Tjagachei , but never got beyond a few prototypes. Since the Minsky Avtomobilny Sawod participated in the development, the name MAZ-545 can also be found in the literature.

History of origin

In the 1960s, the Soviet Ministry of Defense saw the need to replace the Soviet MAZ-537 tank transporter with a new design. It became increasingly clear that the performance of the MAZ-537, mainly due to its motorization, reached its limits in the context of dynamic warfare with extensive, rapidly operating tank formations. At the end of the 1960s, engineers at Minski Awtomobilny Sawods developed two prototypes , the MAZ-545 tractor unit and a version with a ballast bed named MAZ-545A . Both first designs were produced from 1969 to 1970 in Kurganski Sawod Koljosnych Tjagatschei (KZKT for short). The trucks were based on the chassis of the MAZ-537 and outwardly differed only in an elongated driver's cab that could accommodate eight people. In the first drafts, the cabin was extended, but not provided with additional doors. One of the passenger seats had to be folded down so that the crew in the rear row of seats could get out.

However, the main difference to its predecessor was in use the more modern F-38 diesel engine, a variant of the T-34 -Aggregats W-2 consisting of the Tscheljabinski Traktorny Sawod was delivered. In addition, the trucks received a new four-speed transmission. Further modifications were made until the mid-1970s. These included armoring the cabin, redesigning the front and installing two additional doors for the rear row of seats. Neither the MAZ-545 nor the MAZ-545A went into series production because the powerful W-38 tank engines were not available in sufficient numbers.
