ST-26 gallery

The bridge measured 7.35 meters in length and weighed 1,100kg and was intended to support the armoured units equipped with T-27 tankettes and T-26 and BT light tanks, allowing the passage of vehicles with a maximum weight of 14 tons.
This variant of the ST-26 was tested in military maneuvers of 1933 along with two other variants with different bridge laying systems, but it was determined that the cable system used by this version was much easier and more reliable for the battlefield than the others.
The system was composed of a front frame, a rear frame and a cable winch. The bridge was lowered with the help of the winch in about 40 seconds and without the crew having to leave the vehicle. The winch was driven from inside the tank by the engine’s reverse gear mechanism.
Sixty-five ST-26 bridge-laying tanks were manufactured with the cable-laid bridge system of the initial order of 100. Nine of these vehicles participated in the 1939 Winter War against the Finnish demonstrating little mechanical reliability and propensity to breakdowns, although none was lost in combat. In 1941, more than 50 ST-26 vehicles were still in service throughout the Soviet Union, although the majority were in poor condition.
