2. In some certain circumstance it can be used in the working of pushing, jackingand transforming and so on.

3. Easy to operate and used widely.

Notice: according to users' requirement, YDC prestressing jack jack can beconfigured

Applications:

It is matched with prestressed anchorage widely used in the construction of bridgeand buildings, railway and subway, water conservancy and hydropowerengineering .

Features:

YDC Feed-through jacks are the new designed products in our company, are theupgrades of the primary jacks.

1. Using the new seals, to synchronous strengthen the seal-ability under greatpressure.

2. Using special alloy steel with heat treatment process, reducing the cylinder'sexpansion ratio in the tensioning process. So that the life of seals and sealingperformance can be improved about 20%.

3. In the tensioning the operating process, jacks is easily damaged under overpressurebecause of the jack-based pullback clinder, so we added the overpressure valve on thejacks to pressure production.

4. Meanwhile we improved the original of commonly used structure by wire disc andflanged disc, to make the bearing capacity for oil pressure strengthen. So thatenormously reduce the possibility of mechanical damage due to improperoperation.

The Grout Mixer Machine:

JB serious mixer is designed and machined multifunctional mixer which are used with

the HB3 type and 2HB6 type mortar pump. It can be used for various construction and

maintenance, such as building, metallurgy, railway, bridge, Prestressing units etc. The

mixer has small volume and light weight, so that it's easy to installing and handling.

For the previous mixer, the mortar of easy sedimentary bottom is not easy clear. So

we designed the punch forming funnel type mixer, and lengthened the mixer's

working life.

13. Strand Pusher Machine

CS pierce duct machine is mechanical transmissions, roller clamping strand, can betransmitted into, back, and continuously transmitted, also can point start transmitted.It has the features of easy operation, reliable performance, efficiency significantly.The machine reduces the labor intensity, and widely used for large-scale bridges、boxgirder、constitutive objects.One: PurposeIt is the main tool of through strand in building bridges and large building withPrestressing work.Two、Working principleReduction gear drives the driving gear to turn, strand is imported from one end insert,the driving and drive gear withhold strand to move forward into reserved slot, so thatthe strand pass through from the other end to attain the stressing measurement.Three、Main featureThe machine can enter to retreat, integrating pay-off threading for an organic whole.It is easy to operate, convenient to maintain.
