Innovation and Industrial Leadership

The patented two-piece, expendable CONICAL tooth system for earthmoving buckets won design awards following its introduction in 1962, established ESCO as the industry’s leading innovator in both products and metallurgy. Subsequent proprietary product developments (the SUPER CONICAL, KWIK TIP, ZIPPER LIP, HELILOK, and SPERILOK tooth and lip systems, to name a few) kept ESCO at the forefront of earthmoving wearparts innovation, as have patented products for dredging, crushing, conveying, logging, and other industries.
