Question: Does this have a brake?
Document: works great once you get all the grease cleaned off. done every thing I have asked of it so far
Used to raise and lower my mower...works perfectly.
I really like it, and it works great.
I needed to lift a 300lb generator into my truck bed and lift it out at another location. This 1 ton chain block did the trick. Out of the box one of the chains was bound up but a large screwdriver and a little muscle freed it up easily. This is the only project I have use the block for but it has been worth it instead of buying or renting ramps.
I got this so I could build a hoist for my dad to clean his riding mower. We live in southwest Washington and He is obsessed with keeping his new John Deere from rusting out. So instead of having to lift it or push it onto blocks so he can clean the blade housing, we can just hook it up and crank the chain. Works great.
I choose five star because this block is made of good quailty parts and the block did the job ever and over. I will get  many years of use. Yes I would recommend Amazon.com to Everybody because of excellant customer service and fast shipping!! !
I bought this hoist to lift my fifth wheel hitch into and out of the bed of my pickup truck. The hitch weighs about 450 lbs. and this hoist works very well for this job. I have had no problem with the chain twisting or getting stuck. I had read some reveiws before I purchased it and these were some issues that others had. You need to keep the chains from getting tangled, but that would be the same for any brand hoist of this type.
Came with housing damaged and chain hung...able to free it.....works OK and is about what I expected for the price......
Answer: no
