Product Description

Product Description

Introducing the Bridge Tensioning Concrete Prestressed Front Jack, a hydraulic cylinder designed for seamless performance and reliability. This hydraulic jack is an essential tool for any construction project, offering a range of features that ensure efficiency and ease of operation. With its hydraulic mechanism and durable construction, this jack guarantees optimal functionality and longevity. The inclusion of hydraulic parts further enhances its performance, making it an indispensable tool for lifting heavy loads with utmost precision. The steel wire and lifting jack are thoughtfully incorporated to allow for seamless tensioning, ensuring that every aspect of your project is executed flawlessly. Its lightweight design makes it particularly suitable for high-altitude or space-constrained operations. The mono strand jack is specifically designed for single-hole tensioning, and it can be utilized for porous preloading, tensioning, and troubleshooting as well. Additionally, it is compatible with various sizes of high-strength steel wire bundles and steel strands. The installation and construction process is incredibly convenient, as it eliminates the need for rotating the arbitrarily installed working anchor and the radial direction of the jac. In fact, it is even easier and faster to install the tool anchor plate and tool clamp piece compared to the original post-card type. The separate and independent components, including the limit plate, tool anchor, and tension jack, ensure a secure and efficient operation. With the Bridge Tensioning Concrete Prestressed Front Jack, you can expect superior performance, durability, and ease of use, making it an invaluable addition to your hydraulic tool collection.

Description Datils

Multi Mono Strand Jacks can be used for single-hole tensioning and group anchor tensioning one by one. The mono jack is light in weight, easy to operate, high in efficiency, and has a short reserved length of steel strand, which is especially suitable for high-altitude or small-space operations.

Product Features
1. Mono strand jack is mainly used for single-hole tensioning. It can also be used for porous preloading, tensioning, and troubleshooting, and can be applied to high-strength steel wire bundles and steel strands of various sizes.
2. Installation and construction are very convenient: no need to rotate the arbitrarily installed working anchor; no need to rotate the radial direction of the jac; it is easier and faster to install the tool anchor plate and tool clamp piece than the original post-card type.
3. The limit plate, tool anchor and tension jack are separated and independent.
4. Better stability: the conventional post-card tensioning jack for a 3-point piston guide, this series of tensioning jacks for a 4-point piston guide; overcome the 3-point guide eccentric tensioning force often produces the phenomenon of pulling the cylinder scrap jack.
5. It overcomes the shortcomings of cumbersome and inconvenient installation of the overall front card tensioning jack at home and abroad.

FAQ

 

FAQ:
Q1: Whether the rig is used for rock holes or soil holes?
A1: Equipped with different drill bits according to the application object. Rock drilling rigs are equipped with round steel drill impact hammers and rock drill bits. The soil drilling rigs require a twist drill pipe and a three-blade drill bit.
 
Q2: How much tonnage can a bridge jack lift??
A2:  The range is from 50 to 1000 tons, depending on the application needs we have the right choice for you.       

Q3: How many meters is the connection between the jack and the oil pump?
A3: The factory standard is two meters. If you need longer, we will make it for you.
                                                                                                                     
Q4: What is the difference between the hydraulic oil pump?
