SL-TA Self-resetting Bolt Tensioner
螺栓拉伸器的工作原理主要是基于液压传动，利用帕斯卡原理来传递能量。十二
The bolt stretcher applies direct external force to the bolt through a hydraulic cylinder, causing it to be stretched within the elastic deformation zone. This stretching causes slight deformation of the bolt diameter, making it easier for the nut to loosen. During the operation, the design of the hydraulic tensioner allows multiple bolts to be tightened and disassembled at fixed values simultaneously, ensuring even force distribution. This method is not affected by bolt lubrication and thread friction, thus providing more accurate bolt load control.
In addition, the design of hydraulic stretchers also takes into account the requirements of usage space and bolt exposed length to ensure correct use. When using, it is necessary to calculate the set tensile force based on the pre tightening force requirements of the bolt and ensure that it does not exceed the allowable stress of the bolt. For multiple bolts on the flange surface, it may be necessary to stretch them in stages and in order to avoid uneven tensile force between bolts.

SL RCS Low Height Hydraulic Cylinder
柱塞顶部的螺纹孔可用于安装可倾斜鞍座。
Light weight and low height design is suitable for small space, especially in equipment maintenance and disassembly works.
The best performance in a compact and convenient hydraulic jack. SL-RCS cylinders offer a low collapsed height and solid construction enabling safe and stable use in both vertical and horizontal orientations. They include a strong spring return for faster retraction, thereby improving work efficiency.
SL-EPS Multi point intelligent synchronous control jacking system
■ The system adopts PWM pulse width modulation (switching) closed-loop control, relying on the adjustment of the opening time and switching frequency of the switching valve to control the lifting speed of the cylinder, coupled with the electronic control device and displacement, pressure detection system, you can control the lifting speed of the jack, to achieve synchronous lifting of the control of the multi-point, to meet the synchronous jacking, synchronous landing and other functions.
■ Balance equalisation valve adopts the structure of non-leakage cone valve, the main function is to balance the load pressure of the cylinder, so that the jacking cylinder with the load down does not lose pressure and slide down, so that the workpiece will not be free to slide down, even if the jack in the state of blackout can still be loaded and make the jack lifting and lowering are in the state of the oil feed and speed regulation.
