A work machine includes a frame, a traction system, an engine, an implement system, an operator cab with a roof; a machine control system, and a secondary control system. The secondary control system is configured to interface with the machine control system and includes a secondary control device, a control module, a communication module, a base plate, and two rails. The base plate is configured to support the control module and the communication module, and protect the plurality of harness connections. The two rails are configured to support the base plate in an operation orientation and a service orientation and each include a plurality of channels configured to support the base plate in the service orientation.

A self-propelled ground milling machine, in particular a road milling machine, a stabilizer or a recycler, comprising a machine frame borne by traveling devices, a ground milling device mounted on the machine frame having a milling drum box and a milling drum which can be rotated within the milling drum box about a rotation axis running transverse to a main working direction of the ground milling machine, and an operator platform from which the ground milling machine is operated by an operator, having an operator platform floor on which the operator can stand while operating the ground milling machine, having a main floor plate. What is now essential according to the invention is that, in addition to the main floor plate, a side floor plate is provided which can be pivoted about a vertical axis or can be adjusted along a horizontal adjustment axis, and by means of which the standing area of the operator platform can be varied.

A working machine includes: an operating body switchable between a first position to prevent an operator from getting on/off an operator's seat and a second position to allow the same; a plurality of hydraulic actuators whose operation is enabled when the operating body is in the first position and disabled when in the second position; a manipulation member to be manipulated to operate the hydraulic actuators; and a pattern switching member to be operated switchingly to select one from among a plurality of manipulation patterns of the manipulation member to operate the hydraulic actuators. When the operating body is in the first position, at least a part of the pattern switching member is covered by the operating body so that the pattern switching member is impossible or difficult to be operated. When the operating body is in the second position, the pattern switching member is exposed to be operable.

A cab for a construction machine includes: a specified side wall having a side window frame defining a side window and at least one side transparent plate supported by the side window frame; an air conditioner unit having an air conditioner outlet hole; a side beam extending in a front-rear direction along the specified side wall and below the side window frame; and a side duct located above the side beam, extending in the front-rear direction along a lower section of the side window frame, and receiving at least a part of the air blown out from the air conditioner unit, the side duct having at least one side duct vent for blowing out the air toward the at least one side transparent plate.

This disclosure provides an engineering vehicle and an air conditioning system thereof beneficial to improve comfortability of drivers. The air conditioning system includes: an air conditioner body, including a shell with first and second air outlet; a first air supply pipeline, a first end of the first air supply pipeline being connected to the first air outlet; first air support port(s), arranged at an inner front end of a cab of the engineering vehicle and connected to a second end of the first air supply pipeline; a second air supply pipeline, a first end of the second air supply pipeline being connected to the second air outlet; second air supply port(s), arranged at an inner rear end of the cab and connected to a second end of the second air supply pipeline; and a flow distribution device including a flow dividing portion located in the shell.

Power machines and loaders having doors with an integrated display that allows the display of information, such as gauges, user inputs, mapped obstacles, boundaries, etc., that allows the operator of the machine to see the displayed information closer to the line of sight with the work area. The display can show augmented reality information about a worksite.

A working machine includes a machine body an operator seat mounted on the machine body, a front working device swingable upward and downward, the front working device being provided forward of the operator seat and on one side in a machine-width direction eccentric with respect to a central portion of the operator seat, and a front guard provided forward of the operator seat. The front guard includes a first frame member provided forward of the operator seat and on the one side, and a second frame member provided forward of the operator seat and on another side opposite to the one side, the first frame member includes a main rod portion defining upper and lower portions of the first frame member, extending between the upper and lower portions of the first frame member, and provided rearward of the front working device, and the main rod portion is formed to be positioned in a machine fore-and-aft direction closer to the operator seat than the second frame member.
