Crane at BF 2012

My new crane at Brick Fiesta 2012.


It has three functions: slewing, luffing, and main hoist. It is powered by 6x AA batteries in an old Technic battery box. It is controlled by the old Hi-Technic 4-channel RC receiver. Large PF motors power the boom and hoist. A single medium PF motor operates the slewing (turning).


It has a double set of roller bearings in the turntable. The boom has a triangular cross section and is made up of studless beams. It uses braided nylon string (found at the fishing section in my local Walmart).


More pics to come soon!
