A track shoe pad structure assembly is connected to a track chain of a caterpillar vehicle. The track shoe pad structure assembly includes a track shoe pad, a reinforcing unit and an elastic element. The track shoe pad is for connecting to the track chain and includes a notch. One side of the reinforcing unit is detachably connected to the notch, and the reinforcing unit includes a base frame disposed on the track shoe pad and at least one supporting rib disposed on one side of the base frame which is located away from the track shoe pad. The elastic element is detachably connected to the other side of the reinforcing unit, and the elastic element includes at least one recessed trough for containing the supporting rib.

A belt for tracked vehicles suitable for being driven in a closed loop between a front wheel and a rear wheel of the vehicle along a longitudinal direction and for supporting a plurality of transverse bars adapted to stick in the ground along at least a portion of the lower run of the belt loop; the belt comprising a fabric multi-layer internal structure embedded in vulcanized rubber, wherein at least a portion of the fabric fiber of at least one layer is made of aramid.

The invention relates to a welding technical field and provides a crawling welding robot. The crawling welding robot includes a vehicle chassis and two crawler wheels connected to two opposite sides of the vehicle chassis, respectively, wheel carriers of two crawler wheels are movably connected with the vehicle chassis. In this way, when the crawling welding robot moves on a non-planar surface for welding, the two crawler wheels can freely adjust its posture relative to the vehicle chassis to adapt to the surface for welding and improve a degree of fit between the two crawler wheels and the surface for welding, making the moving direction of the crawling welding robot easier to be controlled and reducing a probability of the crawling welding robot slipping or falling from the surface for welding.

A transverse bar for tracks of snow groomers is defined by a section bar and by covering plates fixed to the section bar, which is delimited by an outer surface and comprises a fixing portion to fix the transverse bar to the belts of a track of a snow groomer, and two lateral sides projecting from the fixing portion; the covering plates being arranged along the lateral sides so as to define part of an outer surface of the transverse bar.

A track system for a work vehicle includes a first sprocket having a first diameter. The first sprocket is configured to be coupled to a drive system of the work vehicle, and the first sprocket is configured to engage a metal track and to drive the metal track in rotation. The track system also includes a second sprocket having a second diameter. The second sprocket is configured to be coupled to the drive system of the work vehicle, and the second sprocket is configured to engage a rubber track and to drive the rubber track in rotation. In addition, the first and second sprockets are configured to engage a mounting system, the mounting system is configured to interchangeably couple the first and second sprockets to the drive system, and the second diameter of the second sprocket is greater than the first diameter of the first sprocket.

Provided is a crawler pad with improved durability for preventing foreign materials from coming through between crawler pads, greatly improving the strength of steel cores and improving the integrity of a pad body and a steel core. In the prior one, the typical crawler pad had a problem that its life time keeps shortened because foreign materials such as sands, etc. penetrate through into the space between neighboring crawler pads, and the rubber-made pad body was damaged. Foreign material prevention stops are formed on with protruded from the front and back surfaces of the ground contact part, and function to firstly prevent foreign material from coming into space between two neighboring pad bodies, and overlap inclines are formed on the front and the back lower surfaces of the pad body respectively with inclined downwards so as to be overlapped with those of neighboring another pad body and thereby to form an overlap region and secondly prevent foreign material from coming into.
