Thread: DEFENDER CRANE

May as well show this one I made for the 120.
Its my workshop engine crane that sits doing nothing for most of the time so pulled the bulk of it off the stand and put it on here. The ram gives exra height and the 3000 pound winch gives the lift.
The winches are under $100 on ebay and have cord and cordless remotes.
Good value
Picked up this post hole digger from Quigley today, he cant use it on his Fergy because its a left hand one so we will paint it up and stick it on Gumtree.
Old B section belts make great lifting strops. Engines, gearboxes, you name it. I dont know what they are rated at but havnt broken one yet

They're very handy.

I have a chinese 950KG crane with winch.I payed $350 with postage and its been good.


bolted to my car trailer and a yet to work out how to stop tipping up when lift of the ground.


work has bought jarret back savers. Its best if these are not use to pull vehicles out of bog holes.

Put a jack under the point of the lift. I often use my high lift.

I have two mounting tubes on my trailer. Front left and rear left (wish I had 4 points) and I find that on the front I don't have the same problems with the trailer listing to the lift side when I use it on the front as I have when its on the rear.

BTW: When a steel fabricaton engineer saw my crane, he bought one too, but suggests the base plate is not rated the same as the jib unit. He even contacted the importer who's response is that the crane has the rating and not the base plate. Apparently the problem is the welding on only one side of the webs and the dimensions of the base plate. The problem is the horizontal moment at the base when you have the rated loads at the end of the jib.

The tubes on my trailer are thicker wall tubing and welded into the trailer frame with extra supports.

Sounds like your engineer is smarter than a lot, but they don't take a lot to strengthen up.

No just the extra welding, although the wall thickness could be increased. I guess its because he has the responsibility that what he builds meets code.

The point is that many on this forum may not realise that the base has inadequate strength, so need improvement.
