ABSTRACT:
An improved hydraulically actuated take-up device, for use with conveying members subject to both sudden accelerations and variations in length resulting from changes in thermal loading, wherein a portion of the member is displaced to maintain a predetermined tension therein. Minor corrections are effected gradually through action of a hydraulic damper while a relief valve prevents tension build-up beyond a predetermined limit. The action of the take-up may be reversed to relieve the tension on the member to facilitate periodic maintenance and adjustment.
