Abstract

Anti-skid device for vehicles including a chain provided pulley (1) arranged rotatable on an arm (4) journalled on a shaft (5). The shaft is connected with an eccentric pulley. Cables (7,7') extend around the eccentric pulley and are also fastened to the eccentric pulley. The two cables are in flexible pipes led to an air cylinder (8) and an air spring (9) respectively and movement of arm and chain provided pulley (1) from parking position to working position is achieved by the air cylinder pulling in the cable that in turn turns the pulley and the connected arm (4). A shelf (15) is arranged below the parking location of the chain provided pulley (1). When the chain provided pulleys are parked the chains are drawn over the edge of the shelf (15) and they are thus pulled up from possible contact with the ground. In this way it is possible to use necessary chain length together with a very low mounting of the device.
