ABSTRACT:
This is a chain tensioning system which uses a link section and a hydraulic power section. The link section is rectangular in shape and has a cross-link which is secured by a rod to a load hook external of the link. A securing nut is provided on the threaded rod inside the link frame. A hydraulic power section is used to move the cross-link away from the end of the link section and the securing nut then secures the cross-link in the tightened position. The hydraulic power section is then relaxed and removed and can be used on another appropriate link section.
