KirTech LAB Posted August 4, 2013 Posted August 4, 2013 (edited) Hello all!!! I want to show my funny MOC - Tower Crane Mk II (the first Tower Crane is a history now :) It has four RC functions (four M-motors) and it is telescopic! Its normal height is 145 cm. But it can rise himself up to 210 cm! For the counterweight i used three battery boxes with batteries Video: Thanks for watching!!! Edited January 1, 2020 by desert752 Quote
KirTech LAB Posted August 4, 2013 Author Posted August 4, 2013 Awesome! How much can it lift? It depends on the distance between bogie and tower :) The yellow container on video includes two weight-bricks 2x2x6. For additional stability it is possible to add in the base of the tower four more BB! Quote
timslegos Posted August 4, 2013 Posted August 4, 2013 I am surprised you didn't need more weight/bracing at the bottom! The extendable stand is cool too. tim Quote
EyesOnly Posted August 4, 2013 Posted August 4, 2013 How does it extend? I first thought gear racks but can't see any. Still though a really impressive crane. Quote
Chilis Posted August 4, 2013 Posted August 4, 2013 Omg! That thing is just awesome! Great work! Really cool extendable stand! Quote
MVtechnic Posted August 4, 2013 Posted August 4, 2013 Wow, awesome and beautiful tower crane ! Good job ! Quote
FuzzyBallz Posted August 4, 2013 Posted August 4, 2013 Why is the room completely empty? Ps. Great looking tower crane! Quote
KirTech LAB Posted August 4, 2013 Author Posted August 4, 2013 Thanks all!!! How does it extend? I first thought gear racks but can't see any. There are no gear racks in this model! I used a thread that is winded to the reel! Due to 1:40 gear ratio and a simple polyspast system the extension is provided by one M-motor. For stability improving all the motors are placed in the bottom of the moving part of the crane! Quote
weavil Posted August 4, 2013 Posted August 4, 2013 No that is a propper MOC! Very cool Very awesome MOC. Quote
Bricktrain Posted August 4, 2013 Posted August 4, 2013 Great build. Interesting idea telescoping the tower, many advantages over a jacking frame. Nice use of both studded and studdless beams. Quote
Someonenamedjon Posted August 4, 2013 Posted August 4, 2013 That is just big. Really big. Beyond big. Quote
Doc_Brown Posted August 5, 2013 Posted August 5, 2013 That is awesome! I love the telescopic rise. I build a tower crane after xmas, but it was a failure. I couldn't get the boom trolly thing to run along even with no weigh Any chance of some closer pics so i can see how you did it? Quote
skriblez Posted August 5, 2013 Posted August 5, 2013 The beams, so many beams! Awesome looking crane :) Well done Quote

Ok i see. I've been thinking about a similar solution for a project i might start. Quote

kieran Posted August 5, 2013 Posted August 5, 2013 Really nice, i do love these massive models, just wish I had the space. I think the hiding of the batter box in plan sight is fantastic Quote
Doc_Brown Posted August 6, 2013 Posted August 6, 2013 ahh I see, you have 2 reels! I only had one, and it kept spinning around not doing much. Thanks for that! Quote
