The actuator is not simultaneously secured to both the frame and the loader arm.

A compact utility loader compact utility loader comprising a frame including a lower portion and an upper portion. A width of the lower portion is smaller than a width of the upper portion. The compact utility loader additionally comprises a first track and a second track, with each track being positioned on a side of the frame. Each of the tracks has a width of at least 7.5 inches, and the compact utility loader has an overall width of no more than 36 inches.

A mobile apparatus includes a main frame with displacing means, a rotating sub-frame rotatably connected to the main frame such that the sub-frame is rotatable around a rotation axis relative to the main frame, and a working arm connected to the sub-frame. The sub-frame includes a standing or seating position for an operator. The working arm includes at least two arm segments, and a first arm segment of the at least two arm segments is pivotally connected to the sub-frame around a pivot point located at a distance of the rotation axis. The first arm segment and the sub-frame are configured such that the first arm segment can be moved rearwards onto the sub-frame in the direction of the rotation axis to a rearward position in which the first segment extends over the rotation axis.

A compact utility loader compact utility loader comprising a frame, and a pair of loader arms supported by the frame. The frame includes a right side, a left side, and a bottom side extending between the right side and the left side. The compact utility loader additionally includes an engine mount secured to the bottom side of the frame and spaced apart from each of the left side and the right side of the frame. The compact utility loader further comprises an engine supported on the engine mount.

The invention relates to an expansion sleeve (10), the sleeve being configured to be arranged on an axle (110) to secure the axle in a hole (4), the sleeve comprising: a first and second section (20, 30) with a first and second outer diameter (D11, D2); wherein the first section has a conical shape with a tapering inner wall (22), and an outer wall (24) configured to abut an inner wall of the hole, the second section being configured to axially abut a fastening device (130) arranged at an end of the axle, wherein the second outer diameter is smaller than the first outer diameter, and wherein the second section comprises an inner wall (32) extending with an angle relative the axial direction (A) of the sleeve which is smaller than the angle (β) of the tapering inner wall of the first section.

A first pinhole is formed in a first member in a section facing a second member. A second pinhole is formed in the second member in a section facing the first member. A connecting pin is inserted into the first pinhole and the second pinhole from the side of the machine center. A coming-off prevention mechanism includes a coming-off prevention lever. The coming-off prevention lever can abut the inner end surface of the connecting pin. The coming-off prevention lever is supported by the second member to be able to move between an abutting position of abutting the inner end surface of the coupling pin and a non-abutting position of not abutting the inner end surface.

A boom for a working machine, in particular a concrete-distributing boom for guiding a concrete delivery line, with a plurality of boom arms which can be moved into a working position and which are composed at least partially as a box construction of a plurality of side walls delimiting a cavity region, and with a sealing bulkhead arrangement for sealing a cross section of the cavity region, wherein the sealing bulkhead arrangement has a bulkhead wall provided peripherally with an at least partially encircling sealing groove, and wherein the sealing groove has arranged therein an elastic seal which bears tightly on the inside against the adjoining side walls.

A compact utility loader compact utility loader comprising a frame and a loader arm configured in a vertical-lift configuration. The compact utility loader additionally comprises a link pivotably secured to the loader arm and to the frame, and an actuator pivotably secured to the loader arm and to the frame. The compact utility loader further comprises a track assembly configured to maintain the loader arm in direct attachment to the frame.

Disclosed embodiments include power machines and related structures of lift arms, implement carriers, follower links, and driver links which improve manufacturability, reduce component failures, and improve power machine design and functionality. In some embodiments, lift arm structures include cast lower lift arm portions. The cast lower lift arm portions include contoured upper ends which are sleeved onto contoured lower ends of upper lift arm portions to control stress points and to reduce stresses on welds. The follower link structures can include follower links which are configured to be positioned at least partially outside of the lift arm structure to improve rear visibility. The driver link structures can be configured to be laterally overlapping with innermost surfaces on the lift cylinder, but configured such that as the lift arm is raised the laterally overlapping portions are moved above the innermost surfaces of the lift cylinder.

A rotary working vehicle is provided with: a lower traveling body; an upper rotating body; a rotating frame constituting the bottom of the upper rotating body; a boom bracket supported by the rotating frame so as to be capable pivoting horizontally; a first vertical plate and a second vertical plate, which are raised from the bottom plate of the rotating frame; a swing cylinder provided on the opposite side of the second vertical plate from the first vertical plate and connecting the rotating frame and the boom bracket; a protrusion piece protruding toward the swing cylinder from a side wall of the second vertical plate above the swing cylinder; a hose guide provided to the protrusion piece; and first and second hydraulic hoses which pass above the first vertical plate and the second vertical plate, extend downward from above through the hose guide, and reach the swing cylinder.
