电力的Impact Wrench -够力量拆轮胎吗？

看参数应该够了，不过还是弄个brake bar 吧
 
brake bar 有，其实主要是想看看这个在实际应用中的扭矩到底有多大，看看能不能用在其他地方 ;)
 
经验之谈---电动力矩扳子不建议用于拆螺栓，我曾经把螺栓帽拧坏过（可能是因为设定的力矩不足，光咔哒了），至少先用手动的拧松，再用电动的省力（松了意义不太大）。

力矩扳子是用来紧的。
 
我买了这个，目的是拧木螺钉。还挺好用。卸轮胎我还是用break bar
 
去年在canadian tire 买了一个，计划用来换雪胎，费了很大劲结果只卸下一个螺帽，后来退了。换胎建议用breaker bar 或气动Wrench。
 
真有240 ft-lbs of torque是够用了，很多便宜的气动的也就220 ft-lbs of torque
 
用break bar松动螺母，然后impact wrench卸下。上的时候impact wrench上螺母，不要拧紧，然后torque wrench拧到指定的扭矩。五分钟搞定一个。:p

这个不像是真小鸭啊，最近是那个傻子用这件马甲？ :D

平均 torque电动与气动差不多，但瞬间 torque还是气动有优势。

冲击扳手只有一个指标，就是瞬间的冲击扭矩。
 
没有网名 说:
有没有人用过 这样的 Impact Wrench?

I borrowed it from a friend last year to replace snow tire. It worked well but too heavy on hand.
I bought this one from CT on discount http://www.canadiantire.ca/en/pdp/mastercraft-3ko-corded-impact-wrench-0541216p.html. it is much lighter and also works . I putted four season on this spring using that.


remember you should never over torque the wheel. the standard torque for most wheel is between 80 to 100 lb/ft. For impact wrench has 200lb torque is way enough.
To get the correct torque for wheel .
Using the wrench come with the car, it is about 1 ft long. and push it down with your hand your body weight. Assume your body weight is 160lb, you should get 80 to 100lb torque.

Another tip, go home depot spend few dollars buy a piece pre-cut 1/2 inch cast iron water pipe. Us it as extension of wheel wrench to loose and tight nuts. It worked very well for me before I bought my impact wrench.
