ABSTRACT This invention relates to an anti-skid device for motor vehicles, of the kind in which a friction pulley abuts a drive wheel and the pulley is provided with chain links the free ends of which are thrown between the tire and the ground. In the invention the friction pulley pro- vides strong but resilient anchorage of the chains and is supported on one end of an arm the other end of which is pivotally supported about a journal rigidly connected to the vehicle or the spring system thereof. Pneumatic means controlled by a control means in the driver's cab is provided for swinging the arm and the pulley from a protected non-operative position to a pneumatically re- silient contact position against the tire. The chains preferably have a root portion of rubber coated steel cable to avoid tangling and reduce tire damage.
