Name :tension machine

tension machine of YC series is a kind of feedthrough pre-tensioing jack with a tension rod in the center, having 4 types of tensioning strength, namely: 1000 KN, 2000 KN, 3000 KN, 4000 KN. As the end of the tension rod is connected to the anchor with thread, it can be applied to various forged anchors, chilled iron anchor used for stayed-cable bridge and other similar anchors, as well as pre-tension pulling for pipes. In accordance with actual requirement, the support of two heavy-weight jacks can be replaced with a baseplate and rolling hinged bearing provided by the manufacturer, to be used as a vertical jack, or for horizontal pushing during installation. The customer can also demand a change in thread specifications for the connection of the anchor to enlarge the scope of application.
