The construction machinery and heavy machinery sector is one of the industries where shot peening is most widely used. Especially in parts subjected to high loads, continuous vibration, impact, and fatigue stresses, shot peening significantly increases the reliability and service life of the equipment.

In the construction and heavy machinery sector, shot peening is a critical surface treatment process that extends the life of power transmission, suspension, and coupling components operating under high loads and fatigue. Shot peening is applied to many critical components used by manufacturers such as Caterpillar, Komatsu, Liebherr, Volvo CE, Hitachi, and JCB, to increase fatigue resistance and improve field reliability.
Therefore, the construction machinery sector is considered one of the most important application areas for shot peening technology, following the aerospace, automotive, and energy sectors.
