1.Application
Using for pulling the YM anchor group as well as other type anchorages,through changing the different accessories,it can also be used for DM upset head anchorage and casting anchorage,so it has been widely used in pre-tension working tasks.
2.Usage&Feature:
YCW-B series jacks are light core-through jacks with multifunction
which fit for various anchorages in prestressing tension operation.
The device can be utilized widely in post-tensioning operation for
immense constructions, structures, prestressed concrete bridges,
ground anchorage, marine constructions, foundation anchorage,
etc.
YCW-B series jacks are advanced devices based on their
former structures of YCW, redesigned with high-strength steel,
advanced structures, sealing function, optimization technology.
This new type features tight structure, lightened weight, short
axial length, strands saving by short reserved length in prestressing
strand anchorage. The result of test shows its perfect performance,
durability, flexibility of lifting, convenience of using and repairing.
