doug72 Posted September 7, 2015 Posted September 7, 2015 (edited) Following the build of the 42042 B model crawler tower crane with powered hoist trolley traversing, I decided to build a static free standing tower crane. Progress to date:- Base unit with 3 PF motors complete and drives to turntable unit completed. M motor (1) for slewing the turntable and jib arm / M motor (2) for hoisting / L motor (3) for hoist trolley travel. Turn table unit: transfer gearbox for two drives (2) & (3) to hoist drum and trolley traverse drums completed Only one tower unit at present as easier to work on the top sections - when completed more sections will be added to desired height. During construction the motors are controlled using PF switches to test the drive trains but once completed I will be using the Electric Technic Control unit 2840c02 which can be programmed to operate automatically.

ludov Posted September 7, 2015 Posted September 7, 2015 I don't know if it is intentional, but you're off to a great start for TC8 Quote
doug72 Posted September 7, 2015 Author Posted September 7, 2015 (edited) No - I started building it several days ago and just noted the crane contest today. Doug Edited September 7, 2015 by Doug72 Quote
