China has pulled the curtain back on a “crab-walking” heavy vehicle prototype, reportedly being eyed for transporting, positioning, and potentially launching intercontinental ballistic missiles (ICBMs).
At the heart of the design is a modular wheel system that allows engineers to scale the platform by adding or removing wheel units to handle a wide range of loads.
Moving away from fixed axles and rigid mechanical connections, each wheel can operate independently for propulsion, braking, steering, and suspension.
A centralized electronic control system synchronizes the wheels, letting the vehicle move sideways like a crab, shift diagonally, and pivot on its axis.
Electric propulsion gives the platform a low-observable profile, with minimal heat output, no exhaust smoke, and near-silent operation, potentially aiding concealment.
Center-axis steering also lets the vehicle turn in place, while wheel-by-wheel electronic control supports zigzag climbs on steep slopes and precise maneuvering in confined areas.
The Road Ahead
The project is led by Tsinghua University, with support from the Beijing Institute of Launch Vehicle Technology, Jilin University, Beijing Institute of Technology, and Southeast University.
Funded by the National Natural Science Foundation of China since January 2024, the program focuses on heavy-load logistics for both military and industrial applications.
According to the China Society of Automotive Engineers, the platform is now included in Beijing’s new energy vehicle technology roadmap, signaling plans for wider adoption.
Future models are expected to handle aerospace components and other oversized payloads, highlighting potential use in both military and civilian roles.
