Abstract: A hydraulic tank for a machine is disclosed herein. The hydraulic tank includes a casing defining an interior space and having an outer surface, an inner surface opposite the inner surface, and a return hydraulic fluid inlet extending through the casing. A first concave member is connected to the inner surface of the casing to form a passage. The passage is positioned and shaped to transport hydraulic fluid from the return hydraulic fluid inlet to another location within the hydraulic tank.

Abstract: Ladders and methods for assembling ladders are disclosed herein. A disclosed example ladder includes a mount, a frame including a step, an aperture defined in at least one of the mount and the frame, a lug positioned in the aperture to pivotably and translatably connect the mount and the frame, and a plate. The disclosed ladder also includes a saddle positioned to engage the plate to releasably secure the frame to the mount. The frame can, thus, be displaced from the mount in response to a force to avoid breakage.

Abstract: A fluid tank with a base assembly, a first wall extension member, and a second wall extension member, is provided. The base assembly includes a base member, a first wall, and a second wall. A first end of the base member is integrally attached to the first wall and a second end of the base member is integrally attached to the second wall. Each of the first wall and the second wall includes a stepped portion and a stiffener portion. The first wall extension member includes a first end with a stepped portion and a second end, which is in a first fitted engagement with the stepped portion of the first wall. The second wall extension member includes a first end with a stepped portion and a second end. The second end is in a second fitted engagement with the stepped portion of the second wall.

Abstract: A four-bar linkage ladder is used to provide access to the cab of a mobile machine. The ladder is light enough for manual operation and may include a spring assembly, but avoids the need for the electric, pneumatic, or hydraulic actuators of prior art moveable ladders. The ladder swings from bumper height to an ergonomically desirable height for access and egress and allows passage over uneven terrain without ground contact.
