  • Publication number: 20190170569
    Abstract: A vibration monitoring system at a work site is provided. The vibration monitoring system includes a vibration detection sensor associated with a structure provided at the work site. The vibration detection sensor is configured to generate a signal indicative of vibrations in an area proximate to the structure. The system includes a stationary alert assembly provided at the work site. The stationary alert assembly is proximate to the structure and the stationary alert assembly is positioned such that an alert provided by the stationary alert assembly is perceivable by users operating at the work site. The system also includes a controller coupled to the vibration detection sensor and the stationary alert assembly. The controller is configured to receive the signal indicative of the vibrations and compare the signal with a predetermined threshold. The controller is configured to provide the alert to the users through the stationary alert assembly based on the comparison.

  • Publication number: 20190162296
    Abstract: 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.
