Product Description
Product DescriptionYDC250 jack is a prestressed front-clamping center hole jack used for single tensile reinforcement construction with M15 and M13 bonded tendons. And it is an anchoring system, which is widely used in pre-tensioned and post-tensioned prestressed concrete structures bridges, geotechnical anchoring, and other constructions, especially for high-altitude operations. as it is easy to carry.
A front cassette jack is a tool used to lift heavy objects. It usually consists of a jack and a crossbar fixed to the top. When in use, the bottom of the jack is placed under the object that needs to be lifted, and then the object is gradually lifted by rotating the handle of the jack. The "front cassette" in the name of the front cassette jack means that there are two arms at the bottom of the jack, which can be used to support the front of the object, making the lifting more stable and safer. This type of jack is often used for car repairs or other situations where heavy objects need to be lifted.

The jack is one of the indispensable and important tools in the tension and anchorage construction of prestressed projects. No type of jack is perfect. The jack structure, structural dimensions, and tensioning tonnage limit its scope of use. The QYDC270-200 front clamp hydraulic jack is suitable for single-hole tensioning, group anchor tensioning one by one, troubleshooting, anchor withdrawal, and supplementary tensioning. In terms of prestressed steel strength, it can stretch Φ15.24 steel strands and Φ12.7 steel strands below 2000 grade. If the parts are replaced/removed, precision-rolled threaded bars can be stretched (customers place an order) Rebar, etc.
The jack is small, light, and efficient. The important thing is that the reserved length of the thousand-card steel strand is short (about 260mm). It is especially suitable for operations at high altitudes or in small spaces.
This jack is used with a dual-circuit oil pump greater than or equal to 63Mpa.
Features 1. Adopt the construction method of tool anchor in front to shorten the exposed length of steel strands and achieve the purpose of reducing material costs;
2. Rotate the tool anchor so that its hole position corresponds to the hole position of the limit plate, thereby smoothly penetrating the steel strand, completing the jack installation process, achieving synchronous installation and rapid positioning of the jack and tool anchor, and reducing the installation of the tool anchor plate. Reduce labor intensity and improve tensioning effect:
3. When using the front cassette jack for tensioning, the tool anchor plate is close to the limit plate, which prevents the steel strands from getting entangled in the jack and reduces the probability of slippage and wire breakage during the tensioning process. , and improve the tensioning quality.
Structural featuresA. Both the tensioning cylinder and the return cylinder adopt double seals, which improves sealing reliability. The small cylinder and the second cylinder, the small cylinder and the rear end cover, and the small cylinder and the tool ring are all connected by keys to prevent rotation. They are all sealed with a Grain ring or Sturt ring, which ensures reliable sealing.
B. The second cylinder and piston head are designed as an integral form, which avoids the possibility of failure due to welding of the two bodies or threaded connection of the two bodies. It increases the difficulty of the processing technology but improves the reliability.
C. The improved design of the wear-resistant ring and wear-resistant sleeve avoids the possibility of the assembly coming out due to force and improves product reliability.
D. All important parts bearing force are made of high-quality alloy structure or tool steel to increase hardness and strength.
