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, these blades offer 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 bolt-on cutting edges, heavy-duty end bits, and integrated wear protection to maximise blade life in the toughest mining environments.

Mining SU Dozer Blades - FAQ

What are mining SU dozer blades used for?

They are used in surface mining for pushing, grading, and backfilling where material control is essential but capacity must remain high. These blades are ideal for stockpile shaping, dump maintenance, and site reclamation work.

Which machine sizes are compatible with these blades?

Enstruc mining SU blades are designed for bulldozers over 40t up to 100+ tonnes, including the largest units used in coal, iron ore, and hard rock mining.

Which OEM models are supported?

We manufacture SU dozer blades for:

Caterpillar: D8, D9, D10, D11
Komatsu: D155, D275, D375, D475
Liebherr: PR 756, PR 766, PR 776
John Deere: 850L
Equivalent large dozers from Shantui and other global OEMs

For flat-blade precision work, see our Mining Straight Blades

For high-volume pushing, view our Mining U Blades

For smaller bulldozer models, see our Construction Blades

How do these blades compare to straight or U blades?

An SU blade combines moderate curvature with short wings, offering better control than a U blade and higher capacity than a straight blade. It’s ideal for mining operations that require both precision and productivity.

Can Enstruc customise these blades?

Yes. We offer full customisation, including:

Blade dimensions, moldboard shape, and side wing geometry
Cutting edge styles: single/double bevel, weld-on or bolt-on
End bits: standard, abrasion-resistant, or rock-duty
Added wear protection and reinforcements for high-impact use
Mounting layouts to match OEM or retrofit push arm setups

Do you offer global delivery and technical support?

Yes. Enstruc delivers to mine sites worldwide, with logistics and tech support coordinated for on-time installation and site integration.

Are hydraulic components or arms included?

No. We supply the blade assembly only. Push arms, rams, and hydraulics are not included.
