Overview of Intelligent Tensioning Equipment (Made in China)China-made Bridge Tensioning Mechanical System – This intelligent tensioning equipment is a professional bridge tensioning mechanical system from China, developed based on advanced domestic prestressing technology. Tailor-made for bridge prestressing construction scenarios, it is widely used in post-tensioning prestressing operations of various highway, railway and municipal bridges. As a core equipment to ensure bridge structure safety and improve construction efficiency, it demonstrates the technical strength and exquisite quality of China's bridge machinery manufacturing.
Core Structure & Working Principle
The core of the equipment consists of three key components: system host, high-precision hydraulic oil pump and intelligent jack, combined with professional monitoring software and various sensing equipment, forming a fully automatic and high-precision tensioning control system. The system takes stress as the core control index and elongation error as the calibration index. It collects key data such as working pressure of jack and elongation (including retraction) of steel strand in real time through sensing technology, transmits them to the host for analysis and judgment, and synchronously instructs the oil pump to adjust the parameters of variable frequency motor, so as to realize precise control of tension force and loading speed, and completely get rid of the artificial error caused by traditional manual tensioning.
Technical Advantages & Quality Assurance
As a bridge tensioning mechanical system from China, this equipment integrates the R&D and production experience of bridge prestressing equipment of many domestic enterprises for more than 17 years, introduces advanced European and American production processes, and has passed the ISO9001 international quality management system certification, reaching the leading level in the industry in technological innovation and quality control. The equipment has the core advantages of one-key operation and intelligent control, which can automatically complete the whole process of initial tensioning, 100% tensioning, anchoring and cylinder withdrawal. One host can control two jacks, effectively reducing construction costs and improving operation convenience.
Precision & Safety Performance
In terms of precision and safety, the equipment's displacement measurement accuracy is less than 0.20%, the pressure measurement accuracy is less than 0.9%, and the unbalance degree of double jack tension is controlled within 5KN, ensuring that the tension data accurately meets the design standards. At the same time, it has functions such as automatic storage of tension results, real-time printing and query, and remote monitoring. Multiple safety protection designs can realize intelligent alarm, power-off protection and unloading protection, ensuring the whole construction process is safe and controllable.
Application Scope
The equipment has a wide range of applications, and can complete post-tensioning prestressing construction of various bridges such as precast hollow slabs, precast T-beams, precast box girders, cast-in-place continuous beams, cast-in-place capping beams and cast-in-place steel structure bridges. It adapts to different tonnage construction needs, and can not only meet the large-scale construction of large bridges, but also adapt to the refined operation of small municipal bridges. It provides an efficient and reliable tensioning solution for bridge construction in China and even the world, helping China's bridge technology move towards the world.
