Basic concept of crawler tows

Tracked drags are traction systems used in heavy machinery that use chains articulated with rollers to move over uneven surfaces or difficult terrain. These systems allow a greater contact surface with the ground, which improves stability and load capacity compared to conventional tires.

Its use is essential in sectors such as construction, mining and agriculture, where the terrain presents obstacles or conditions that make the mobility of wheeled vehicles difficult. In addition, tracked tows help distribute the weight of the equipment, minimizing the pressure exerted on the ground and reducing the risk of sinking.

Main elements of the track system

The track drive system is made up of several key elements that work together to ensure efficient and stable movement. These components include the track chain, support rollers, drive gears and tension wheels.

The track chain is made up of articulated metal links that form a continuous band. These links usually have shoes or plates that provide additional traction and protection against wear. Support rollers help distribute the load and allow the track to ride smoothly on the drive wheels and idlers.

Drive wheels, usually located at one end of the system, drive the chains using toothed gears that fit with the links. For their part, the tension wheels maintain the appropriate tension of the track, preventing it from coming off or loosening during operation.

Materials used in manufacturing

The materials used in the manufacture of crawler drags must guarantee high resistance to wear, abrasion and mechanical fatigue. Generally, special high-alloy and heat-treated steels are used to increase the surface hardness of the links and shoes.

Additionally, some manufacturers incorporate additional coatings or treatments, such as chrome plating or the use of rubber compounds on the pads, to improve adhesion and protect the base material against corrosion and impact.
