25 Ton Mono Strand Jack


25 Ton Mono Strand Jack Features

1. The YDC250QX jack adopts the front clip type (that is, the tool anchor is in the front). The steel strand can be stretched with a reserved length of 200mm, which can save the material of prestressed tendons.

2. During the tensioning process, the jack can automatically clamp the prestressed tendons and retract the anchor, thereby reducing labor intensity and improving efficiency.

3. The jack is designed with accessories with various functions, which can be selected according to needs during work.

4. The jack will not spin when working, which avoids the excessive elongation of the steel strand due to rotation.
