Grousers are devices intended to increase the traction of continuous tracks, especially in loose material such as soil or snow. This is done by increasing contact with the ground with protrusions, similar to conventional tire treads, and analogous to athletes' cleated shoes. On tanks and armoured vehicles, grousers are usually pads attached to the tracks; but on construction vehicles they may take the form of flat plates or bars.

Systems and methods which provide improved pipeline mats are provided herein. Such mats may include one or more of a plurality of the inventive features. For example, some embodiments provide for replaceable top surfaces which allow for portions of the mat to be replaced if in need of repairs, e.g. after excessive wear and tear, rotting, and the like. Further, embodiments may include a built-in air wick channel which allows for airflow to travel between stacked mats, thereby reducing the potential for a mat to rot. Some embodiments may also include a structure which allows for the mat to be moved using a forklift. Such structure may include grouser strips which help direct the forklift while also protecting the top surface from wear. Additionally, such structure may include built-in chocks disposed on the lower surface of the mat. These chocks may also facilitate the air wick channel.

A crawler-type fire-fighting robot includes a crawler and rollers. The track has two rows of tooth irons arranged in parallel, and the bottom of the roller has two rows of tooth irons arranged correspondingly to the track tooth irons, so that the two rows of tooth irons on the track and the two rows of tooth irons on the rollers are of the same polarity. In this way, the rollers are occluded on the track due to the polarity of the tooth irons and the tooth irons. The rotating shaft of the roller rod drives a water spray device, which includes a driving motor installed in the rollers, which is used to drive the rollers to rotate and pass through the machine body. The air blower sprays powder and liquid to extinguish the fire through a nozzle opening to the front at the bottom of the roller, and simultaneously pushes the robot crawler forward. The invention changes the wheeled walking mode of the conventional fire-fighting robot, and utilizes the self-laying support function of the crawler belt to make the rollers run smoothly on the crawler belt and pass through various obstacles in the fire field to activate the fire extinguishing device to extinguish the fire in the fire field.
