"The Chinese "crab walker" design is roughly 6 meters long, and two meters wide, including its legs. It has eight main legs, four on each side of the body, and has two rear mounted legs to brace itself for stabilization during firing; there is also another stabilization leg installed in the front). The size of the Crab Walker would make it capable of being airlifted by heavy helicopters like the Mi-26 and its prospective replacement, the Sino-Russian Mi-46. During transport, the Crab Walker's three stabilizing legs would be retracted to allow faster movement.

In the present design concept, the Crab Walker's main weapon is a 30mm autocannon, which is also found on Chinese ZBD-86, ZDB-03 and ZBL-09 infantry fighting vehicles. Presumably the 30mm autocannon could be swapped for other remote weapons station, like anti-tank guided missiles or a mortar. Also, there are bulges located in front and behind the 30mm autocannon, which are likely to house communications and sensor equipment. "
