A chain system is provided that is attached to a continuous track of a tracked vehicle. Embodiments of the chain system can include cross chains that extend from a side chain, and a hook is disposed at a free end of each cross chain. To attach the chain system to the track, the hooks are attached to an inner edge of the track on a top surface of the track. Once all of the hooks are attached, the ends of the side chain are attached to each other and the chain is secured to the track to improve the traction of the track and the tracked vehicle.

The tool includes an elongate rigid bar with fixed chain leaders extending from the bar near ends of the bar. A removable chain leader is provided between these two fixed chain leaders. In one form of the invention, the bar is hollow and a pin translates within this hollow core. A slot in the bar allows a proximal link of the removable chain leader to pass into the hollow core of the bar where the pin can removably capture this proximal link. Because the removable chain leader is provided on the bar, it can initially be captured to the bar for use along with the fixed chain leaders to position a tire chain onto a dual wheel pair. Then, the removable leader can be removed from the bar and act as a handle on a middle elongate section of the tire chain to assist in connection thereof.

A steering control method and system for a vehicle may determine whether the snow chain has been mounted by comparing the number of times of vibrations of a certain peak or more detected by respective wheel speed sensors with respect to a current vehicle speed with a predetermined value, and selectively controls the operations of an AFS and a RWS according to the position of the wheel on which the snow chain has been mounted, when it is determined that the snow chain has been mounted.

A tire chain includes a side member. An attachment bracket is secured at a first end region to the side member. The attachment bracket is formed at a second end region with a slot and with a channel. A crosslink member has an endless link at one end. The endless link defines an opening and is located in the slot so that the opening intersects the channel. A rod extends through the channel and the opening of the endless link and is secured against removal from the channel, whereby the crosslink member is secured to the attachment bracket.

An anti-skid device with mounting from the outside for wheels, particularly with alloy rims with central hole, includes: a central body intended to be placed at the hub of a wheel on which the anti-skid device is to be mounted; arms radially protruding from this central body and terminating in terminal elements intended to be placed on the tread of the tire; chain segments connected to the terminal elements forming a ring on the tread of the tire; a device designed to be fixed to the rim of the wheel; a connecting element between the device and the central body of the anti-skid device; and a tensioning mechanism placed in the central body which can be actuated to pull the connecting element and bring the central body closer to the wheel hub. The device is an expansion device fixed in the central hole of the rim of the wheel.

A device for self-extraction of a vehicle using a towing rope made in the form of a gripper, including at least three arms arranged circumferentially and having a shape that allows installation on the drive wheel of the vehicle. The device has a traverse with a threaded opening in the center where the threaded rod is installed, at the end of the rod facing the vehicle wheel in the operating position, a hub stop heel is installed. The gripper's arms have two L-shaped parts, the first parts with their side that is oriented along the axis of the device are pivotally installed on the traverse, and the second parts are rigidly connected to the first parts at a section of their sides oriented in the radial direction from the axis of the device.

A supplemental tire tread for installation on an outer surface of a solid tire, the outer surface of the solid tire defining opposed sidewalls and a tread surface that extend between the sidewalls. The supplemental tire tread has a tread body having an outer tread surface, an inner surface, and an attachment for attaching the tread body around the tread surface of the tire. The inner surface of the tread body has tire supports with tire receiving receptacles that open away from the inner surface of the tread body and receive the solid tires when installed. The tread body has anchor receptacles that engage anchors that pierce the solid tires to support the tread body against relative rotation of the solid tire and the tread body.

A disabled vehicle moving device configured to allow movement of a vehicle includes a sleeve made of a flexible material and configured to be mounted over a radially outer surface of a tire/wheel assembly of the vehicle that is locked for rotation. A cover is made of a flexible material and configured to be mounted over the sleeve and the tire/wheel assembly of the vehicle. A lubricant is arranged between the sleeve and the cover. The cover rotates relative to the sleeve and the tire/wheel assembly to allow the vehicle to be moved.

The invention relates to an anti-skid chain (1) for tires (3), in particular for bogie axles, wherein the anti-skid chain (1) has two laterally stable guide chains (5) which, when installed, are arranged to the side of the treads (9) of the tires (3), wherein the anti-skid chain (1) has a flexible chain mesh (7) which extends between the two guide chains (5), and wherein at least one guide chain (5) has chain links (15, 17) which are interconnected in an articulated manner by means of joint pins (19) in the circumferential direction (U), and at least one rotation-blocking element (27) by means of which a maximum joint angle (35) between two interconnected chain links (15, 17) is a defined. In order to prevent lateral pulling of the anti-skid chain (1) and, at the same time, to provide an anti-skid chain (1) that is easy to produce, according to the invention, a part of the rotation-blocking element (27) is located on at least one of the joint pins (19).
