ESCO standard open and closed take-up assemblies 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 assure that every open and closed take-up assembly meets or exceeds quality standards. All castings and ancillary components are manufactured in North America.

ESCO manufactures a complete line of standard fully engineered Open and Closed Take-Up Assemblies, ranging from cable diameters of ½" to 6", and stocks many sizes. Standard Take-Up lengths are 9", 12", 15", 24", 36", 48", 72", 84" and 96." Special take-up lengths are available upon request. Assemblies are available self-colored or galvanized.

All cast components used in take-up assemblies 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. Threaded rods are manufactured to ASTM A193 Grade B7, nuts to ASTM A194 Grade 2H, and washers to ASTM F436 Hardened Steel. Coarse UNC series threads are standard, and fine series threads are available upon request.

ESCO standard open and closed take-up assemblies conform to the dimensional requirements of Federal Specification RRS-550D, and exceed the mechanical requirements of RRS-550D.

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