K-3 Bomb Lift Truck By Note: This item is currently in storage. The K-3 bomb lift truck was designed for use with the Convair B-36 bomber. Because of the bomber's mammoth size, the B-36's top bomb shackles were more than 17 feet from the ground. Hand-cranked hoist and cable loading of the large bombs was too hazardous, so the Air Force ordered a self-powered weapons loader. The first K-3 was delivered in 1950, followed by eight more in the next four years. The K-3 could pick up a bomb of up to 5,000 pounds and lift it to the maximum height of 17 feet, 9.9 inches in 60 seconds. In addition to bombs, the K-3 also could raise fuel tanks, pylons, rockets, missiles, ammunition cans and maintenance platforms. Donated by Mr. W.N. Oswald.
