ESCO specialty mining products are designed to withstand the full minimum breaking load (MBL) for rope and strand without permanent deformation.

ESCO uses state-of-the-art design, manufacturing, testing and inspection technology and procedures to ensure that each casting meets or exceeds quality standards. All castings are manufactured in North America.

ESCO manufactures a complete line of fully engineered specialty mining products, including pendant line sockets and take-up assemblies for Bucyrus draglines and shovels – as well as open and closed flanged sockets for Marion machines.

All cast components are manufactured to ASTM A148 Grade 105-85. ESCO uses the argon oxygen decarburization (AOD) refining process to purify and strengthen cast steel alloys. No-bake sand molding techniques are used for excellent dimensional control and superior surface finish.

ESCO Specialty Mining Products conform to the manufacturing, testing, dimensional, assembly, and inspection requirements of Bucyrus-Erie Specification SD-2155.

To ensure complete traceability, each casting is individually serialized. Upon request, certified documentation on chemistry, mechanical properties, heat treating and non-destructive testing requirements are available.
