An endless-track traveling apparatus includes a casing, pulleys having axes arranged in parallel in the casing, a motor for driving the pulleys, and an endless track wound on outer circumferential surface portions of the pulleys to rotate together with the pulleys and move on a traveling target. The endless-track traveling apparatus further includes: a plate-shaped member disposed in contact with the endless track and opposed to the traveling target in a space surrounded by the endless track, and fitted in the casing; a magnet fixed in the casing to attract the traveling target; and an elastic member having one end in contact with an inside of the casing and another end in contact with the plate-shaped member, and urging the plate-shaped member in such a direction as to press the plate-shaped member against the endless track.

There is provided a planar member having a flat portion that makes contact with the inner circumferential surface of an endless track at a position at a traveling subject side with respect to a virtual straight line that connects a vertex, at the traveling subject side, in the outer circumferential surface of a first pulley and a vertex, at the traveling subject side, in the outer circumferential surface of a second pulley.

Monitoring vehicles comprising track systems or tires to obtain information regarding the vehicle, including information regarding the track systems or tires, such as an indication of a level of wear, a rupture like a break, a puncture, chunking, de-bonding, etc., which can be used for various purposes, such as, for example, to convey the information to a user (e.g., the operator); control the vehicle (e.g., a speed of the vehicle, operation of a work implement, etc.); transmit the information to a remote party (e.g., a provider such as a manufacturer or distributor of the track systems or tires); etc.

A suction traveling device includes: a main pressure reducing chamber, sub pressure reducing chambers communicating with the main pressure reducing chamber and disposed in drive parts, ventilation holes on a same side of the sub pressure reducing chamber as suction holes and communicating the sub pressure reducing chambers and suction holes, and an open/close unit for releasing the ventilation holes when a pressure in suction chambers formed by a wall surface and the suction holes is equal to a pressure in the sub pressure reducing chamber and for closing the ventilation holes when the pressure in the suction chambers is higher than in the sub pressure reducing chamber. When the ventilation hole is closed, a gap of a size preventing the pressure in the sub pressure reducing chamber from affecting the pressure in the other suction chamber is formed in the ventilation hole.

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 tracked climbing vehicle containing a compliant suspension apparatus to prescribe the distribution of forces on the adhering members in the tracked climbing machine. The compliant suspension apparatus is configured to negotiate irregularities in a climbing surface without the vehicle tracks losing full surface contact and adhesion by distributing the loads from the climbing machine chassis to the adhering traction members in a specific prescribed fashion. The apparatus thus avoids exceeding the allowable force in any adhering traction member and significantly improves the performance of the climbing machine.
