Start

As early as the 1830s shortly after the birth of the steam car, some people conceived to give the car wheel set wood and rubber “tracks”, so that heavy steam cars can walk on soft land, but the early track performance and use effect is not good, until 1901 when Lombard in the United States developed a traction vehicle for forestry, only invented the first track with good practical effect. Three years later, California engineer Holt applied Lombard’s invention to design and build the “77″ steam tractor.

It was the world’s first tracked tractor. On November 24, 1904, the tractor underwent its first tests and was later put into mass production. In 1906, Holt’s tractor manufacturing company built the world’s first gasoline internal combustion engine-powered crawler tractor, which began mass production the following year, was the most successful tractor of the time, and became the prototype of the world’s first tank developed by the British a few years later. In 1915, the British developed the “Little Wanderer” tank followed the tracks of the American “Brock” tractor. In 1916, the French-developed “Schnad” and “Saint-Chamonix” tanks followed the tracks of the American “Holt” tractors. Crawlers have entered the history of tanks for nearly 90 spring and autumn so far, and today’s tracks, regardless of their structural forms or materials, processing, etc., are constantly enriching the tank treasure house, and the tracks have developed into tanks that can withstand the test of war.

Constitute

Tracks are flexible chainrings driven by active wheels that surround the active wheels, load wheels, induction wheels and carrier pulleys. Tracks are composed of track shoes and track pins. Track pins connect the tracks to form a track link. The two ends of the track shoe are holed, meshing with the active wheel, and there are inducing teeth in the middle, which are used to straighten the track and prevent the track from falling off when the tank is turned or rolled over, and there is a reinforced anti-slip rib (referred to as the pattern) on the side of the ground contact to improve the robustness of the track shoe and the adhesion of the track to the ground.
