My intent on this blog is to better inform people in the industry and companies that have cranes in their facility.<br />You are correct that the many hoist on the market today do not have a load brake but only a motor brake. Like you said, because of the friction gearing that is on the market today there is not a need to have load brakes. <br />The load brakes I was discussing are Weston style load brakes.Weston style load brake is what you see on P&H or Shepard Niles. There are other types of load brakes out there. Like you stated Shawbox has a different style load brake. Shawbox uses an electric solenoid. I focused on Weston because this is a traditional style load brake which is very common in the industry. I will see what I can do about putting something together to explain all the different load brake styles. That is a good idea.

I've already passed of the link to your blog to some of our inexperienced techs.<br /><br />Touching on what mrmikeb wrote. I've been trying to wrap my head around how a clicking pawl can tell you that the load brake needs to be adjusted. Can you clarify what model of hoist that it's on? It's the first I've heard of this.<br /><br />For example, Shawbox, a very common brand doesn't use ratchet pawls in their hoists. Nor does Whiting, Detroit, or R&M. A clicking ratchet in a Yale EW series usually means that the friction spring in the pawl has broken. The same goes for P&H Hevi-lift.<br /><br />Also, I think it might be a great idea to touch on the newer package hoists coming out that don't have load brakes due to better friction gearing and squirrel cage motors. And of course eddy brakes and VFD dynamic braking.<br /><br />Again, thanks for doing this and keep up the good work!MattMhttps://www.blogger.com/profile/07987308689298097401noreply@blogger.comtag:blogger.com,1999:blog-2401928500968492592.post-48689507343597511532012-01-11T10:31:47.060-08:002012-01-11T10:31:47.060-08:00Thank you Mr.Mike.

If the ratchet and pawl are always hitting each other, eventually it will wear out. Harrington is a good hoist but you do want to be careful load brakes that are designed to hit the pawl and ratchet assembly. For the most part load brakes are designed so the pawl does not hit the load brake ratchet.LeCrane Chroniclehttps://www.blogger.com/profile/10128970482514813973noreply@blogger.comtag:blogger.com,1999:blog-2401928500968492592.post-63023233254027868312012-01-08T08:44:38.521-08:002012-01-08T08:44:38.521-08:00Well written.

The KITO or Harrington ES series and some Coffing EC hoists allowed the pawl to lightly touch the ratchet.mrmikebhttps://www.blogger.com/profile/16550241026414172466noreply@blogger.com
