One of our instructors, Randy Bucher, recently got the honor of sitting in Bigge’s 125D, an A-Frame Derrick crane with 1,520 ton capacity.
This derrick crane has a stationary counterweight of 5,600 tons. The crane runs on a track around the counterweight providing 360° operation. The twin boom length is 560 ft and requires 2-1/2 inch cable.
