A tunable hydraulic vibration damping mount comprises a universal outer housing, inner sleeve, main spring assembly, bottom compliance assembly, and inner bushing. Each of a plurality of flow channel members comprises a cylinder having a common inner diameter, a common outer diameter, and a helical track having a cross-sectional area and a length defining a volume of the helical track. The helical track of each flow channel member defines a different volume. A selected flow channel member is positioned between the inner bushing and the outer housing and between the main spring assembly and the bottom compliance assembly. The selected flow channel member provides a selected dynamic performance of the damping mount.

A hydraulic excavator includes a revolving frame forming a support structure, a cab that is disposed to be positioned on a front side of the revolving frame and in which an operator gets, and a plurality of vibration isolating members that are disposed between the revolving frame and the cab to support the cab on the revolving frame in a vibration isolating state. Further, an intermediate connecting member is disposed for connection between the revolving frame and the vibration isolating member and for a height position adjustment of the cab to the revolving frame. The intermediate connecting member is fixed to the revolving frame from a lower side.

An apparatus comprising a chassis, a compartment and a safety system. The chassis may comprise a chassis base, curved rear chassis pillars and inclined front chassis pillars. The compartment may comprise a compartment base and curved rear compartment pillars. The safety system may be configured to (a) receive a signal and (b) activate a safety measure in response to the signal. The chassis supports the compartment. The compartment provides seating for occupants of a vehicle. The signal indicates an amount of force. The safety measure comprises (a) lifting a front of the compartment from the chassis, (b) rotating the curved rear compartment pillars along the curved rear chassis pillars and (c) absorbing the force with the chassis base while the compartment is lifted.

Disclosed embodiments include power machine frames, and corresponding power machines such as skid steer loaders, which have fully arcuate access aperture features providing improved access to components within a chain case or otherwise positioned interior to the frame.
