عمر أمين Posted March 12, 2017 Share Posted March 12, 2017 Hello Everyone I am trying to choose between different types of power hammer, the leaf spring one and the coil spring one Can anyone please help me in this? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted March 12, 2017 Share Posted March 12, 2017 Now when you say coil spring vs leaf spring do you mean like a Little Giant type hammer vs a Champion type hammer or do you mean a tire hammer type hammer vs an appalachian/rusty type hammer? Also "better" requires more details. Easier to build? Easier to maintain? Easier to tool? Easier to buy used? Takes up less space? It's sort of like asking which is a better vehicle a 15 person van or a full sized pickup truck---you have to know the details to say which is better for what.

Frosty Posted March 12, 2017 Share Posted March 12, 2017 Welcome aboard, glad to have you. If you'll put your general location in the header you might be surprised how many of the Iforge gang live within visiting distance. Both types of spring have a pretty rudimentary if necessary job in a mechanical power hammer some advantages or disadvantages per type like everything else. What are your expectations of the spring or more importantly the hammer? Are you buying or building? What do YOU think the difference is? We need more information to provide a meaningful answer.

عمر أمين Posted March 12, 2017 Author Share Posted March 12, 2017 Dear Thomas and Frosty, I mean by the coil spring hammer, the one in these links https://goo.gl/IB3yCQ https://www.youtube.com/watch?v=q3nUCwQ6JQk And I mean by the leaf spring hammer, the one in these links https://goo.gl/cE7tQB https://www.youtube.com/watch?v=KPZSYzDCRVE I mean by "better", I need to compare them in according to cost and easiness to manufacture and build Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted March 12, 2017 Share Posted March 12, 2017 If you are just building one for personal use then I suggest you look into building a tire hammer. If you plan to manufacture a large number of them then you need to evaluate the designs against your manufacturing capabilities. The reason that the Little Giant is so very popular here in the USA is that the manufacturer sold them on time payments and so nowadays there is a large base of them around and it is even possible to buy parts for them. Other designs were perhaps better but now are "orphan" machines and all parts have to be custom made. Quote Link to comment Share on other sites More sharing options...
عمر أمين Posted March 17, 2017 Author Share Posted March 17, 2017 You mean by "tire hammer" and "little giant" the coil spring hammer? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted March 17, 2017 Share Posted March 17, 2017 Yes the home built tire hammers usually use a coil spring like the Little Giant. I have seen a couple with the leaf spring arch like Champion hammers used. Quote Link to comment Share on other sites More sharing options...
Frosty Posted March 17, 2017 Share Posted March 17, 2017 The tire in a "tire hammer" is typically an easy and reliable clutch mechanism unlike a Little Giant's conical clutch and wooden clutch shoe design. All the spring designs have their advantages and disadvantages both to use and to manufacture. I believe the main concern is your intent. Are you planning on building power hammers for sale? Or are you planning on building one or a few to use? If you're thinking of manufacturing power hammers you have a lot more to think about than the ram linkage spring. I don't know about what you need to have a meaningful opinion. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
