Wholesale Mono Strand Pulling Jack
YCWB series of Monostrand Hydraulic Jack is my company based on YCWE series jack on the structure, the fourth generation of new lightweight Jack size is further improved and optimized after the successful launch of the. It is a replacement product of YCWE series jack with small volume, light weight, good sealing performance, high strength, high reliability and versatility.
It is widely used in post tensioning construction. Different accessories are used, which can pull OLM clip group anchor and various types of clip group anchor, DM upsetting anchor, LZM cold cast anchor and so on.
YCWB series Mono Strand Pulling Jack.YDC250QX type jack is a Mono Strand Pulling Jack for OLM15, OLM13 single bonded tendon tensioning construction, but also the OLM anchorage system,
It is widely used in pre tensioned and post tensioning prestressed concrete structures, bridges, rock and soil anchorage projects, especially suitable for high altitude operation and easy to carry.
YDQ stressing jacks technical parameters:
Nominal tensile force 255kn
Nominal oil pressure 50MPa
Area of tension piston 5.11x10-3
Return piston area 1.94x10-3
Return oil cylinder working pressure
Stretch stroke 200mm
The minimum diameter of center hole 17mm
Shape size 110x529mm
Minimum workspace 750x110
Mass 20kg
Steel strand reserved length > 220mm
The monostrand jack should be used in conjunction with the electric high pressure oil pump. The anchorage is a flat anchor.
It is mainly used for the whole tensioning of the group anchor on the bridge, the tensioning steel strand, which is mainly used with the prestress anchorage and the tensioning equipment.
It has the following characteristics:
1. A new type of seal is adopted so that the seal strength of the seal is enhanced synchronously when the cylinder is subjected to high pressure.
2, special alloy steel cylinder material and heat treatment process are adopted to reduce expansion ratio of cylinder block during tension process, so that seal life and sealing performance will be increased by 20%.
3, the tension in the process of operation, Jack return overpressure damage problems in jack, increased the overpressure protection valve for pressure relief protection; at the same time the original several common used wire disc and flange type structure was improved, the strengthening of the oil pressure jack backhaul capacity, greatly reduced the possibility of improper operation of damage of jack.
