Mining dozer Semi universal blade

Enstruc mining SU dozer blades combine the load-holding capacity of a universal blade with the control of a straight blade, which is ideal for heavy-duty mining operations where versatility is essential. With a semi-curved moldboard and moderate side wings, the semi-universal blade offers high material retention and accurate dozing performance across a wide range of conditions.

Built for mining-class dozers up to 100+ tonnes, each blade is delivered as a complete blade assembly, ready for direct fitment to OEM push arm systems. Manufactured from high-tensile, abrasion-resistant steel, our mining SU blades are engineered to withstand extreme impact, abrasion, and cyclic loading. We offer custom configurations with extreme duty bolt-on cutting edges, end bits, and integrated wear protection to maximise blade life in the toughest mining and earthmoving environments.
