ABSTRACT:
A manual tong is disclosed which includes a continuous composite continuous belt, a handle assembly, and a jaw assembly, where the continuous composite continuous belt is designed to take the place of the convention linked chains used currently in manual tongs. The continuous composite continuous belt is held in place by a set of pins associated with the handle and jaw assemblies. Replacement of the linked chains with the continuous composite continuous belts improve tong safety, improve ease of use, lower cost, make adjustment easier and make continuous belt replacement easier reducing down time and increasing tong utility (one tong can be used for different pipe diameters with a simply adjustment of the continuous belt or a simple replacement of the continuous belt with a different size continuous belt.
