螺栓拉伸器與液壓扭矩扳手都是工具中的一種，而這種工具體積大，重量沉，工作效率可是高于普通的各種工具。再熟練的拆裝技師，可能都比不上一個螺栓拉伸器的工作效率呢。因為螺栓拉伸器這款工具可以同時改變多個螺母的松動或者緊實力度，或者可以同時拆卸多個螺母。那么，螺栓拉伸器與液壓扭矩扳手的差別有哪些呢？
Bolt stretcher and hydraulic torque wrench are both one kind of tools, but this kind of tool is large in volume, heavy in weight, and its working efficiency is higher than ordinary tools. No matter how skilled the disassembly technicians are, they may not be as efficient as a bolt stretcher. This tool can be used to remove multiple nuts or bolts simultaneously. So, what are the differences between bolt stretcher and hydraulic torque wrench?
一、在狹小空間受限度有所差異
1、 In the narrow space, the limit is different
由于螺栓拉伸器具備高效工作的能力，在設備檢修、維修的工作過程中身都會看到他的身影呢?但對于一些先進設備來說，使用它絕對沒有問題。而對于一些老舊款設備而言，可能使用液壓扭矩扳手會更適合，尤其是在空間狹小的縫隙里操作的時候，使用螺栓拉伸器就沒有使用液壓扭矩扳手更順手。這就是他倆另外的不同之處。
Because the bolt stretcher has the ability to work efficiently, we will see him in the process of equipment maintenance and repair. But for some advanced equipment, it is absolutely no problem to use it. For some old equipment, it may be more suitable to use hydraulic torque wrench, especially when operating in a narrow space, it is easier to use bolt stretcher than hydraulic torque wrench. That's the other difference between them.
二、使用范圍比較廣泛
2、 It is widely used
螺栓拉伸器是在液壓扭矩扳手功能基礎上，研發而成的一款高效率工具，它具備較強的抗拉度。當在設備內部需要對大號螺母進行拆裝或者緊實的時候，如果同時操作多個螺母，它就比液壓扭矩扳手效率高，同時可以保證工作進度。但是如果在特定空間內，螺栓拉伸器就不一定能有液壓扭矩扳手好用，但是多數情況下肯定是螺栓拉伸器被常用，被使用的用途也會很廣泛。而液壓扭矩扳手被使用的就不是很廣泛，這就是兩種工具的一些不同之處。
Bolt stretcher is a high efficiency tool developed on the basis of the function of hydraulic torque wrench. It has strong tensile strength. When the large nut needs to be disassembled or tightened inside the equipment, if more than one nut is operated at the same time, it is more efficient than the hydraulic torque wrench and can ensure the work progress. However, if in a specific space, the bolt stretcher may not be easy to use with hydraulic torque wrench, but in most cases, it is sure that the bolt stretcher is commonly used and will be widely used. The hydraulic torque wrench is not widely used, which is some of the differences between the two tools.
