This is a model of a typical heavy duty pedestal crane used in the offshore construction and transportation industry. It is not modeled after any specific crane, but incorporates the typical characteristics.

Details of the Model:
• Maximum Lift: 48.0 lb (21.8 kg) (SEE DETAILS HERE)
• Scale: 1:30 (approximate)
• Power: 12V battery (from cordless drill)
• Controls: 4-channel R/C from HiTechnic
• Total Lifting Lines: 2 (main hoist and whip hoist)
• Counterweight: water (in plastic bags) and battery
(later, steel was used as ballast)
• Total Height: 6.5 feet; 2.0 meters
• Boom Length: 5.5 feet; 1.7 meters
• Total Motors: 14
• Thrust Roller Bearing: 29 Wheel Hubs (30.4 x 14 VR)
• Total Building Time: 71 hours

The only modified parts used were all the sheaves (pulleys). The cross-axle holes were bored out so that they spun independently of the axle. The non-Lego parts used were the battery, string, water (later, steel ballast), and the R/C controls from HiTechnic.
