Quarry excavator Bucket wear runners

Wear runners are wear-resistant steel wear blocks that are installed along the underside or sides of quarry excavator buckets to protect against heavy abrasion, impact, and ground scuffing.

Enstruc Quarry Bucket Wear Runners (wear blocks) are designed for 54-136 tonne class excavators. Depending on the application, our wear blocks are fitted to buckets on Cat 352, 374, 395, 6015; Komatsu PC490, PC650, PC900, PC1250; Hitachi ZX490, ZX530, ZX690, ZX890, EX1200; Volvo EC480, EC500, EC530, EC550, EC750, EC950; Develon DX490, DX530, DX800, DX1000; Sany SY500, SY550, SY650, SY750, SY870, SY980, SY1250; Hyundai HX480, HX520, HX800, HX1000; Liebherr R956, R960, R972, R978, R992, R998; and other similar excavator models. For larger excavators, see our Mining Excavator Wear Runners. For smaller excavators, see our Construction Excavator Wear Runners.

Yes. They slow down wear on large contact surfaces, reducing bucket underside wear and extending overall bucket life.

Enstruc wear runners are mechanical (bolt-on) for a quick, secure installation. When the wear block has worn out, simply remove the fasteners and slide the old wear block off, and slide a new wear block on and retighten the fasteners.

Using proprietry wear material we cast the wear runner which undergoes advanced heat treatment for extreme wear and impact resistance. For detailed information please contact us.
