Abstract: A bogie for a train vehicle includes two side frames, each side frame including two axle openings, each axle opening disposed on a corresponding end of the respective side frame, each side frame further forming a central slot disposed between the two axle openings; two wheelsets, each wheelset including an axle passing through two opposing axle openings between the two side frames; and a central beam having two ends, each end being slidably disposed within a corresponding central slot such that the central beam is disposed generally parallel to the axles of the two wheelsets and is slidable towards or away either of the two wheelsets.

Abstract: The present disclosure provides a load carrying member for a machine. The load carrying member includes an outer shell, an inner shell disposed within the outer shell. The inner shell is pre-stressed. The load carrying member also includes a pin disposed through the outer shell and in contact with the inner shell to add stress to the inner shell during operation of the machine.

Abstract: A counterweight removal and installation system for a counterweight attached to a frame of the machine is provided. The counterweight removal and installation system includes a lever member having a first end and a second end. The lever member is rotatably coupled to the frame at the first end. The first end is positioned below a center line of the counterweight and the second end positioned above the counterweight. The counterweight removal and installation system further includes an arm coupled to the lever member and transversely extending thereof, the arm positioned above the counterweight. The counterweight removal and installation system further includes an end of a first flexible connection member attached at the second end of the lever member. The counterweight removal and installation system further includes a second flexible connection member provided between the arm and the counterweight.

Abstract: A machine system installed on a marine vessel is provided. The marine vessel includes a first mounting portion and a second mounting portion. The second mounting portion is positioned proximal to the first mounting portion. The machine system comprises a machine, an enclosure, and a power unit. The machine includes a frame and a work unit. The frame is rotatably mounted on the first mounting portion of the marine vessel. The work unit is positioned on the frame of the machine. The enclosure is mounted on the second mounting portion of the marine vessel. The power unit includes a power source for the machine. The power source is removably positioned within the enclosure, such that the power source is isolated from the machine. The power source is connected to the work unit.
