doug72 Posted October 2, 2015 Posted October 2, 2015 (edited) Currently building an alternative horizontal jib for use on my TC8 tower crane entry after the contest is over by using that base & tower to mount the alternative jib. Design of jib done completed after two attempts and approximates to a triangular cross section. A hoist trolley traversing system was devised using a single rope system. Found that using studless beams for the trolley to run on causes wheels to drop as they passed over joints between the 15L sections - now replace by studded Technic 16L beams with 8x1L plates on top edge for the wheels with rubber tires to run on. Winding drum house: 1st attempt used a design based on the TC8 design but did not look right and did not allow hoist trolley to get in close to the tower. Then a "Eurecka" moment relaxing in a hot bath ! Turn the winding house so that it is vertical. Next step design / build the tower top, jib support tie rods and the counterweight jib. This time the counterweight box will be filled with lead ! Edited October 2, 2015 by Doug72 Quote
