amiga4001 33 #1 Posted September 15, 2019 First try rotating does not work,lifting and extending does,lift uptill now is 220kg. Rotating works with a steeringhouse off a visa connected to a hydraulic cylinder,maybe pulling out off line with one will try to add another cylinder and try again. supporting legs is new model which can swivel over the tires to give the crane as much support as possible,still needs work to get it more stabil. takelproef.mp4 10 3 3 Share this post Link to post Share on other sites

Stormin 9,975 #4 Posted September 15, 2019 Be handy for lifting logs onto a trailer or saw bench. 2 Share this post Link to post Share on other sites
ZXT 2,394 #5 Posted September 16, 2019 I have car engines and heavy stuff spread out all over the place. I can see where something like that would be extremely handy to have! Great job building it. I would probably have to build a platform between the tractor and the hoist to set whatever it was to get it where I needed, since there's no telling how far I'd need to move it. I didn't even know that there were any WH's in the Netherlands! I wonder what all countries they're in. Share this post Link to post Share on other sites

amiga4001 33 #8 Posted November 15, 2020 New rotatingsystem in use,works ok.It is a flywheel of a toyota aygo and the gearwheel on a hydraulic engine,rotatingspeed is fine. For the moment powered with a small electroengine/hydraulicpump about 0.7 KW so maximum load now 140kg. Mechanical no stress but you can hear the sound the electroengine makes to complain fur the load. Next time I will put the wheelhorse in front of it see how it maxes out. kraantestklein.mp4 3 5 1 Share this post Link to post Share on other sites

DennisThornton 4,769 #10 Posted November 15, 2020 More! Details and closeups! I'd like one even if I had to push it to load where I wanted it dropped, still got to secure and then release the load so I'd be up anyway. Share this post Link to post Share on other sites
amiga4001 33 #11 Posted November 15, 2020 I downloaded some detail pictures onto the gallery. Seems I maxed out my upload limit with the video in this topic. The crane has a front axle which can steer and a pole? to connect it to my wheelhorse tractor. The steering part is as the crane main shaft done with a axle hub only upside down works great! The main shaft off the crane is bolted onto a hub and axle-end from a truck trailer. These axles are 9ton and normally it is fitted with a truck wheel off course so it can withstand the forces. Onto this hub I bolted the flywheel and main shaft. The legs for stabilization must be pulled out so the crane stays small so it will fit through small passages. Still these legs are not done,I like to make them hydraulic in the future so work for the future,still they seem to do the job for now. Hoping the wheelhorse will pull some more it at least has much more power then the electric engine. If it exceeds 300kg I would be a very happy crane operator. 1 Share this post Link to post Share on other sites
DennisThornton 4,769 #12 Posted November 15, 2020 Not sure what the video limits are. Perhaps someone will jump in. Close up pictures when you have time would be helpful. Nice build! Share this post Link to post Share on other sites
