Prestressing Pulling Jacks

The pressure with a front jacks, internal transfer check with jack, can prevent in drawing process, cylinders and pistons patch of relative rotation between. Jack built-in repeatedly tools used in the work can be anchored and automatic tool clamping and loosen, the anchor clamp pressure of jack is through the roof of JinYou return oil and simplify the structure of jack, jack repairs and maintenance.

YCQ front-arresting jack is a core-through front- arresting jack with the tool anchorage being able to be used repeatedly in it. It can automatically tighten and release the tool anchorage wedge in the operating and is mainly used in the single stressinsg of various bonded and unbonded tendons. YCQ jack adopts the new sealing element, lightened design and anti-turning devices which will the jack from rotating during stressing.
