A soil processing machine includes a machine frame having two longitudinal members positioned parallel to a machine longitudinal direction and spaced from each other transversely to the machine longitudinal direction, and two transverse members positioned extending transversely to the machine longitudinal direction and spaced from each other in the machine longitudinal direction. A soil processing roller is supported on the longitudinal members such as to be rotatable about a roller rotational axis and positioned between the transverse members in the machine longitudinal direction. A coupling assembly couples the machine frame to another machine frame of the soil processing machine or to another machine. A chassis assembly includes at least one height-adjustable chassis unit supported on the machine frame.

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 working machine includes a track guide for restraining a crawler belt from displacement in a left-and-right direction. The track guide includes a front attachment member and a rear attachment member each detachably attached to a crawler frame, and a right contact plate member and a left contact plate member laid between the front attachment member and the rear attachment member. Each of the right contact plate member and the left contact plate member includes a restraint plate and a reinforcement plate, and is supported on the front attachment member and the rear attachment member with an outer surface of the restraint plate and an upper surface of the reinforcement plate both being in surface contact with the front attachment member and the rear attachment member.

A kit and corresponding method can be used to convert wheels of a power machine to track assemblies, such as to convert a four-wheeled power machine to a quad track power machine. A stub shaft (346) can be secured to an axle (328) of a power machine (300) and can be configured to support a track frame (366) of a track assembly in place of a wheel (319). A bearing (368) can be secured to the stub shaft (346) and a bushing (376) can engage the axle (328) to rotatably support the track assembly relative to the axle (328). Pieces of a segmented sprocket (378, 380) can be separately secured to a hub (306) of a power machine (300) to help install and drive a track of a track assembly.

A work machine includes an undercarriage assembly. The undercarriage assembly includes a chassis and a ground-engaging mechanism for rotating around the chassis to move the work machine. A pair of rails is coupled to the chassis. A pair of sliders is coupled to a front-assembly. The sliders are aligned with the rails and movable relative to the rails to facilitate movement of the front-end assembly relative to the chassis.
