The bogie further includes a spring and/or damper element, which at one end portion is hinged on the bogie body and at the other end portion is hinged on the second end portion of the swing arm and by means of which the swing arm is capable of being applied with force. A vehicle, in particular a forestry vehicle, is also disclosed having at least one bogie axle with such a bogie.

An example method includes receiving, at a first frequency, sensor information indicative of an actual pressure level of a pilot fluid signal in a pilot line connecting an outlet port of a pilot supply valve to a pilot port of a main valve; determining an estimated pressure for the pilot fluid signal in the pilot line at a second frequency greater than the first frequency; determining a pressure estimate error based on comparing the actual pressure level to the estimated pressure; determining a pressure level error based on comparing the estimated pressure to a commanded pressure value; and operating the pilot supply valve in an open state to provide the pilot fluid signal to the pilot port of the main valve until the pressure level error is less than a threshold value.

Disclosed are apparatus, systems, and methods, including a ground transport drive container comprising an outer container having a cuboid shape and comprising a plurality of fittings for securing the outer container to another apparatus; and a drive wheel assembly. The drive wheel assembly comprises one or more wheels and a deployment mechanism secured to the one or more wheels. An actuating member actuates the drive wheel assembly between a stowed configuration and one or more deployed configurations. In the stowed configuration, the drive wheel assembly is housed entirely within the outer container. In the one or more deployed configurations, the drive wheel assembly extends from the outer container.
