I recently got an engine crane,or hoist,cherry picker,whatever you want to call it--I've been using it to load heavy junk in my truck--but the dam things teeny iron wheeled casters are a joke--one pebble and its impossible to move it,and forget moving it if one wheel goes off the edge of the asphalt!--your DONE!..no way I can move that ballbuster around alone!--since the casters were spilling bb's all over the place,now they wont swivel very easy, making life even more miserable....its usless to be able to LIFT something if you cant roll it to the truck--and I have lots of heavy stuff on the dirt and grass to move too... I'd seen them with trailer tires in the back so you could tow it to the job with a car or truck--and I had a set of "Holmes" dolly wheels off an old wrecker I found in the landfills metal pile--too scary to tow a car with(rusty,bearings kinda rough,etc)--so I got out the sawsall and cut them up--I made them slide into the square tubing pretty easy,only needed a peice of pipe they slid onto to "bush" it to fit inside the square tubing more snugly,and used a "pinch" bolt like the ones the crane had with welded nuts to secure them--that took care of the rear wheels....BUT Now I'm stumped as to how to rig up the front wheels!--if I just make them slide on and off,and they dont "steer",it wont be very useful(A 'Straight Ahead Only" crane ain't much use!)--and making a complete "steerable" front axle for it is a lot of work... I'd hoped to be able to tow this thing around the hard with my lawn tractor and clean up the yard easier--I was thinking maybe I only REALLY need wheels in the front (non steerable)and I could attach the rear of it to the tractors hitch somehow so only the front wheels touch the ground--then it would act like a trailer and turn easy,right??-...I made the dolly wheels easy to remove so I can use it with the original casters(the big tires wouldn't fit under most cars )-- But I'd prefer to leave it with the big tires for "yard" use behind my tractor,I have another nicer crane in the shop I could use for engine swaps... but how can I make it "steer" with all 4 tires on the ground??---I'm thinking I'm going to have to make a front end like a kids "little red wagon" to tow and steer it,thats a lot of time and work-(and the crane would be facing the tractor--maybe the REAR wheels should be the "steering" and the front rigid??) -I even thought about making it a "trike",a 3 wheeler,but that seems like it would be too tippy and scary..anyone ever put a lift kit and bigger tires on your cherry picker for off road use??--If so,speak up!--I'm desparate!-- I saw just such a rig on the net a few weeks ago,but I cant find the site I saw it on,stayed up til 5am looking!!...stupid me didn't "save" the web adress!... Any ideas,photos or suggestions appreciated!...I'm thinking of just making a swivel base for the "boom" part of the hoist and bolting it to my 82 K20,and say screw the 4 wheeled platfrom!--I already have a nice swiveling crane with an electric winch thats on a flatbed,but I havent finished building the trailer its sitting on,it needs to be wired up,etc---plus the trailer isn't registered yet...and scrap prices dropped ten bucks a ton this week already! --HELP!
