Description

YDC post-tensioning hydraulic hollow jack is the fourth-generation new lightweight jack successfully launched after further improvement and optimization of structure and size on the basis of the original structure of YDC. This new type features tight structure, lightened weight, short axial length, stands saving by short reserved length in prestressing strand anchorage. The hydraulic hollow jack can be used in pre-tensioning and post-tensioning. Equipped with different accessories, the hydraulic hollow jack can tension M clip anchors and various types of clip anchors, as well as DM pier head anchors, LZM cold cast anchors, etc.

There are 25 tons, 60 tons, 80 tons, 100 tons, 150 tons, 200 tons, 250 tons and 300 tons of small tonnage hydraulic hollow jacks, and the tension stroke is 200mm (can be customized). The small tonnage hydraulic hollow jack is suitable for tensioning single steel strand and 2~15 hole finishing rebar. The jack is small in size and light in weight.

Large tonnage hydraulic hollow jack

Large tonnage hydraulic hollow jack

The large-tonnage hydraulic hollow jack is a hydraulic jack above 400 tons, with a tensioning stroke of 200mm (can be customized). The large tonnage hydraulic hollow jack is suitable for 16~32 hole finishing rebar. The jack has good sealing performance, high strength and reliability, and strong versatility.

Long stroke hydraulic hollow jack

Long stroke hydraulic hollow jack

The tension stroke of this long stroke hydraulic hollow jack is 400mm. Generally, the tension stroke is designed to be 200mm. We can lengthen or shorten according to the user's needs, and customize the special itinerary for the user.

Intelligent hydraulic hollow jack

Intelligent hydraulic hollow jack

The intelligent hydraulic hollow jack adds a displacement sensor to the conventional hydraulic hollow jack. The function of the displacement sensor is to measure the length dimension of the extension of the jack piston. In the past, the elongation was measured manually, but now it is measured by the displacement sensor, which is controlled intelligently.


Hydraulic Hollow Jack Features

1. On the basis of the original YCW series hollow jack, the hydraulic hollow jack adopts high-strength steel, improves the structure and sealing performance and the processing method. It is a light new type of jack.

2. The characteristics of the hydraulic hollow jack are compact structure, light weight, short axial length, and short reserved length at the anchorage of the prestressed strand bundle, which can save strand material.

3. It has been proved by experiments that the hydraulic hollow jack has good performance, durability, flexible hoisting, convenient use and maintenance.

4.The hydraulic hollow jack is mainly used in the construction of bridges and other projects in conjunction with products such as prestressed anchors and tensioning equipment (electric hydraulic oil pump, PLC intelligent tensioning system).


Application

Application of Hollow Hydraulic Jack
