What Are The Main Smart Tensioning Equipment?

Intelligent tensioning and tensioning equipment is a device for tensioning pre-stressed steel bars when making pre-stressed reinforced concrete products or components. There are many kinds. There are:

①Mechanical tensioning equipment. Use mechanical transmission method for tensioning. It is generally composed of three parts: clamping, tensioning and force measurement. There are two types of manual tensioner and electric tensioner. Manual tensioners include screw type tensioners and reel type tensioners. Electric tensioning machines include electric winches or electric screws. This type of machine has the characteristics of small tonnage, long stroke, simple mechanical structure, flexible and convenient use, and low cost. Mainly used for tensioning steel wire in pre-tensioning pedestal. If there is no hydraulic stretching machine, a larger tonnage mechanical stretching machine can also be made to stretch a single steel bar;

②Hydraulic tensioning equipment. It is composed of hydraulic jack, oil pump, external tubing, etc. According to the structure of hydraulic jack, there are pedestal type, tie rod type, core type and cone anchor type. It has the advantages of large force, small size, light weight and convenient operation. It can stretch thick steel bars, steel strands, steel wire bundles, etc. Applicable to post-tensioning method and post-tensioning self-anchor method construction;

③Electric heating tension equipment. It is mainly composed of electric transformers, wires, wire clamps and other instrument tools. The use of electric heating tension steel wire is suitable for tensioning curved or round products or structures, such as cement pressure pipes, oil tanks, pools, etc.
