Similar to the LCC-1 Sno-Train, the Overland Mark 2 came with a jib crane. It was designed for moving freight and even changing a tire if needed. The jib crane had a usable capacity of 20 tons. But, the weight capacity changed based on the angle of the crane arm.
The cargo size limitations also changed depending on the jib crane angle. For example, if your working load was 10,000 pounds, the maximum width crate the Mark 2 could load was 8 feet 6 inches.
