Abstract:
It is known to retro-fit continuous track units to wheeled vehicles. This apparatus permits this to happen such that the continuous track units are securely attached and so that the vehicle can withstand shock loads and be operated over rough terrain without them becoming dislodged. This is effected by a first portion (240) attachable to the vehicle's chassis (75), the first portion arranged to substantially surround the drive hub (25), a second portion (250) including a support arm (280) for supporting the continuous track unit, the second portion releasably attachable to the first portion, and a drive sprocket (260) releasably attachable to the drive hub for transferring torque from the drive hub to the continuous track unit so as to rotate the track in use with the wheel removed and the apparatus attached to the vehicle.
