A work machine includes a frame, one or more drive members coupled to the frame, an engine for providing power to the one or more drive members, one or more components coupled to the frame, and a monitoring system for monitoring wear of the one or more components. The system includes a user interface and a controller. The controller is in circuit communication with the user interface. The controller is configured to receive information inputted into the user interface by a user and send an alert notification regarding the servicing of at least one of the one or more components based on the received information.

Work machines and systems for monitoring wear of components of work machines

A screed assembly, for a paving machine, may include a frame, a main screed and a screed plate. Additionally, the screed assembly may include an overload support system mounted on the screed assembly. Further, the overload support system may be configured to contact the surface extending beneath the screed assembly and to support the screed assembly during transport on the surface.

Overload support system for a paving machine screed assembly

A screed assembly for a paving machine may comprise a main screed having a frame with a fixed width, and an extension screed slidably connected to the main screed and configured to extend laterally from the main screed to a fully-extended position. The extension screed may include a deflector, an inner plate proximate a central axis of the main screed, and an outer plate opposite the inner plate. At least one extender tube may extend between, and may be fixed to, the inner plate and outer plate. Each extender tube may have a shell comprised of a first material with a second material disposed therein, the second material offering increased stiffness to the extender tube so as to restrict flexion of the extender tube when the extension screed is in a fully-extended position.

Stiffened screed extender tube

An asphalt paver machine includes a main screed and an extender screed. The extender screed is coupled and configured to move laterally relative to the main screed. The extender screed includes a first screed carriage movably coupled to the main screed by a first cylinder and a second cylinder diagonally arranged relative to one another, and a second screed carriage movably coupled to the first screed carriage by a third cylinder and a fourth cylinder diagonally arranged relative to one another.

A method for cleaning a screed of a paving machine includes activating a vibration generator to induce a vibration into the screed such that the screed is excited at a resonant frequency of the screed to cause dislodgement of a residual build-up of a material from the screed.

A screed extension for a main screed frame of a paving machine includes an upper frame and a lower frame disposed below the upper frame. A height adjustment system is disposed between, and coupled to, the upper and lower frames. The height adjustment system is configured to moveably couple the lower frame to the upper frame. The height adjustment system includes an upper mounting plate affixed to the upper frame, and a lower mounting plate affixed to the lower frame. The height adjustment system also includes a first tube that is located between and coupled to the upper and lower mounting plates such that a first end of the first tube is configured to establish an interference fit with the upper mounting plate and a second end of the first tube is configured to establish an interference fit with the lower mounting plate.

A screed assembly for a paving machine is disclosed including a main screed portion and a screed extension portion being laterally exterior to the main screed portion. Furthermore, a screed extension tube is coupled to a screed frame and a screed extension portion frame, the screed extension tube adjusts a width of the screed extension portion. The screed assembly may further include an extension tube support mechanism having a bushing circumferentially surrounding the screed extension tube and disposed within a bushing recess defined in the screed extension portion frame. The extension tube support mechanism further having a retainer ring that circumferentially surrounds and is in direct contact with at least a portion of the bushing, and the retainer ring is capable of being adjusted between the bushing and the screed extension portion frame to eliminate an uncontrolled movement of the screed extension tube and the screed extension portion.

A system associated with a machine is provided. The system is configured to engage with a vehicle. The system includes a first frame and a second frame to support a first roller and a second roller, respectively. The first roller and the second roller are configured to abut a first and a second set of ground engaging members, respectively, of the vehicle. The system further includes a pin member to couple the first frame and the second frame. The first frame and the second frame are moveable relative to each other about a rotating axis defined by the pin member. The system further includes an actuating member coupled between the first frame and the second frame. The actuating member is configured to move the first frame and the second frame about the pin member.
