Abstract: Provided is a system or the like which can achieve improvement in remote operation efficiency of a work machine by improving an efficiency of calibration processing. A determination result of whether a remote operation factor corresponds to an actual machine operation factor is recognized by a first support processing element 121. “The remote operation factor” is a factor defining an operation setting of a remote operation mechanism 211 included in a remote operation apparatus 20. “The actual machine operation factor” is a factor defining an operation setting of an actual machine operation mechanism 411 included in a work machine 40. Processing of making the actual machine operation factor correspond to the remote operation factor is executed by a second support processing element 122 on a requirement that the determination result is negative.

Abstract: A work machine cooling system for cooling primary power source cooling fluid for a primary power source may include a primary power source cooling unit and a second power source cooling unit fluidly connected so that primary power source cooling fluid flows from the primary power source through the primary and secondary power source cooling units is discharged back to the primary power source. The work machine cooling system may further include a primary cooling fan disposed proximate the primary fuel cell cooling unit to discharge airflow onto the primary fuel cell cooling unit, and a secondary cooling fan disposed proximate the secondary fuel cell cooling unit to discharge airflow onto the secondary fuel cell cooling unit. The secondary cooling fan may be turned off until the primary cooling fluid temperature is greater than a transient event threshold temperature indicating the occurrence of a transient thermal event.

Abstract: Both a control for limiting operation of a machine body and a control for raising engine speed are achieved when an obstacle is detected. To this end, a machine controller performs operation limiting control by conducting a control for reducing the speed of the engine when the machine body does not require engine speed increase control and an obstacle is sensed by obstacle sensors, and the machine controller performs supply flow rate reduction control for reducing the flow rates of the hydraulic fluid supplied to hydraulic actuators from a hydraulic pump when the machine body requires the engine speed increase control and an obstacle is sensed by the obstacle sensors.

Abstract: A compact utility loader compact utility loader comprising a frame, a first track and a second track positioned on either side of the frame, and a pair of loader arms. The loader arms are configured to couple with an attachment via a hitch plate and a hitch pin. The compact utility loader is configured such that as the loader arms are raised and lowered, the hitch pin follows a path approximately defined by a curve ƒ(x)=4.641e0.34x. The value “x” represents a horizontal direction and the function ƒ(x) represents a vertical direction.
