Telaketjut

Telaketjut, or continuous tracks, are belts that loop around wheels to propel a vehicle. They are common on tanks, bulldozers, tractors, and some snow machines. They spread the vehicle’s weight over a large area, reducing ground pressure and improving off-road mobility.

Construction: An endless belt made of metal links or rubber blocks passes around a drive sprocket, an idler, and sometimes return rollers. Track tension, guided by a tensioner, keeps the loop aligned. The outer surface has lugs or shoes to grip terrain.

Types: Steel tracks provide durability for heavy-duty use; rubber tracks are lighter and quieter, favored on civilian machines. Some designs mix materials or use modular links for easier maintenance. Track width, pitch, and shoe design influence load capacity and grip.

Performance: Benefits include low ground pressure, better traction on soft or rough ground, and the ability to traverse uneven terrain or obstacles. Drawbacks include heavier weight, higher maintenance, more complex steering, longer setup times, and often higher cost.

History and usage: The concept emerged in the early 20th century and was rapidly adopted for military vehicles, improving mobility across challenging terrains. Steel tracks dominated military use for much of the 20th century, while rubber and modular designs gained prominence in construction, agriculture, and civilian applications in the late 20th and early 21st centuries.

Maintenance and safety: Regular inspection for wear, proper tension, and cleaning to remove debris are essential. Check drive sprockets, rollers, and return rollers for damage. Damaged tracks should be replaced promptly to prevent derailment or loss of vehicle control.
