Hydraulic cable tensioner

摘要

A hydraulic cable tensioning device having a main body and tensioning yoke formed from aluminum and being capable of delivering 5,000 psi to tension a cable bearing a barrel and wedge assembly such as in a mine roof bolt or a cable truss. The body defines a pair of cavities which each receive an elongated member bearing a piston which together act as dual action hydraulic cylinders. A cable receiving bore defined in the body receives a cable gripping member to grip the cable while the tensioning yoke pushes against the barrel and wedge assembly in response to forces from the hydraulic cylinders.
