If you have any question or sugestion I would be happy to answear .

Looks great. I never thought about mounting a kick stand on the front of mine. Sure beats using an apple box.

Sergiu,

Great job! You have me wanting to build a completely new jib. :-)

What are the dimensions (length, width and thicknesses) of the square tube that you used?
Is it all aluminum tube, alternatively a mix of Aluminum and steel tube?

I like the double square tube arrangement on the pivot section.
Had you thought of using a rectangular section there?
If so, why did you go with two square tubes?

Bill

The dimensions for square tubes are :
60x60x4
50x50x4
40x40x4

All tubes are from aluminium . Others parts like "U" from the pivot point or camera plate are from steel for a strong durability

I used 2 square tubes instead of 1 rectangular becouse boom arm and counterweight arm are slideing in thoses 2 60x60x4 tubes for a minimum lenght when the crane is transported .

Sergiu,

Thank you, I am putting together a shopping list now. ;-)

What were the lengths of the tubes I'm guessing around a meter and a half?

Bill

Dont forget the beer in your shopping list :)

If you have other question I'm glad answering you !

No beer ;-( I'm a rummy! :-) gotta have my Myers

What were the lengths of the tubes I'm guessing around a meter and a half?

Bill

Nice man! liking the look of this! :)

Correct. The lengths of the bars are :
1500 mm for the 60x60x4 bar
1550 mm for the 50x50x4 bar
1600 mm for the 40x40x4 bar

The extra length between bars is for safety reasons where the bars are united .

Damn, I have a good eye and it works in inch and metric!! LOL

Thank agin for your help.

Bill

the link is dead!

works for me :)
BEAUTIFUL!

Link is working , I just review it and everything is fine . Maybe was a timeout from server .

Sergiu,

Nice bit of work. I checked out your site and it is pretty impressive and I like what you can do with it!!

I was wondering, what the bill for the materials and motor would come to when you are finished??

After seeing this i might cancel my boat building project for awhile to build a crane like this!!

oops.. I think its banned in China somehow. I will have to wait till I get home then. Cant wait to see the good work! Planning on building one real soon too..

The motorized head cost me aprox 2'200 $ ( it's a cameraturret PT20 ) with shipping and taxes , the tripod ( Cartoni ) - 700 $ and the rest of materials aprox 700 $ .

Hope this help you decide what you what to build :) !

I will post soon another video with the creane on a music concert .

Hi Sergiu, that is one nice looking crane. I have a few questions that I hope u can help me with :)

1. How are the bearings done for the pivot point? Are they fitted onto the bracket?
2. I noticed a rotating interface between the tripod and the braket that holds the crane itself. Did u machine that with some kinda bearings below as well?

I m having headaces with the bearings now.. dun know how to complete that part of the design.. hopw u can give me some photos if possible. Thanks!

Link updated and working again.

What can you tell me about the performance of the head? would you be comfortable using that is a profesional envirment.
I have been lokking at the Jimmy jib lite, but I don't have that kind of cash. I need that over the crowd concert shot.

The head perform very well. No problems until now. You need to practice a little bit to become comfortable with the joystick. I usually operate this crane alone and using in professional environment ( tv and film work, events and stage concerts ).

how much camera can that thing hold?

about 10-11 kg
