lifting jack (used with anchorage)

YCWE series light jack is designed to meet the needs of the users and engineering , It has maintained and developed the traditional YCW series‘ advantage of advanced technology and good quality . Through computer analysis and optimum combination design, after repeated experiments, (especially cylinder of the jacks is made with progressive technologies of the prestress) .this kind of jack is small size, light weight ,good seal , high strength , safty and reliable . The product can be widely used in different types of the anchorage in prestressed engineering with different attachments.
