An autonomous stability control system may include a sensing system configured to collect position and orientation data about a work machine on a construction site and a controller. The controller may be configured to receive or generate a work path plan, operate the work machine according to the work path plan, continually or periodically monitor the orientation data from the sensing system, compare the orientation data to a vibration slope threshold, and, when the orientation data exceeds the vibration slope threshold, deactivate a vibration system of the work machine.

Work machine stability control system

A construction machine having a frame and at least one compaction member is provided. The machine also includes a propulsion system having a hydraulic motor adapted to rotate the compaction member. The propulsion system also includes a hydraulic pump fluidly coupled to the hydraulic motor via a high pressure line and a low pressure line. The high pressure line allows flow of a fluid at high pressure from the hydraulic pump to the hydraulic motor. The low pressure line allows flow of the fluid at low pressure from the hydraulic motor to the hydraulic pump. The propulsion system further includes a hydraulic valve fluidly coupled to the low pressure line and a casing of the hydraulic motor. The hydraulic valve selectively allows flow of a portion of the fluid at low pressure from the low pressure line to the casing for cooling of the hydraulic motor.

Propulsion system for a construction machine

A machine for milling a surface of a roadway is provided. The machine includes a frame and an operator station arranged on the frame. A canopy assembly including a canopy and a support assembly is provided. The support assembly supports the canopy on a portion of the frame forward of the operator station such that canopy is movable between a raised position and a lowered position. The canopy and the support assembly are configured such that in the raised position the canopy extends over at least a portion of the operator station and in the lowered position the canopy is arranged in a substantially flat orientation relative to and adjacent an upper surface of a portion of the frame forward of the operator station.
