One or more techniques and/or systems are disclosed for identifying field conditions of a field. Site conditions of a target site affecting machine sink can be identified using real-time or historical data. Soil conditions, weather conditions, moisture levels, and other factors may be used to determine whether a target site may result in machine sink of a target piece of equipment. The machine sink information can be identified for a target area, that comprises a target site, and a machine sink map can be generated for the site. Target equipment specifications can be used to determine whether the target equipment may effectively traverse the target site based on the machine sink map. Further, a travel path may be generated for a piece of target equipment based on the machine sink map, site conditions, and the equipment specifications.

The present disclosure provides a fatigue management system capable of managing fatigue of each portion of a construction machine more accurately than conventional systems. The fatigue management system S includes: a stress calculation section S1 that calculates stress acting on a plurality of portions of the construction machine based on the output of a sensor 18 attached to a part of the construction machine; a damage degree calculation section S2 that calculates the cumulative damage degree of each portion of the construction machine based on the stress calculated by the stress calculation section S1; and an index value calculation section S3 that calculates a fatigue index value, which is a weighted value of the cumulative damage degree, for each portion.

A vehicle with a track system including a track for traction of the vehicle on a ground can be monitored (e.g., during operation of the vehicle) to obtain information regarding the vehicle, including information regarding the track system, such as a temperature and/or another characteristic of a wheel of the track system sensed by a sensor associated with that wheel, which can be used to inform a user (e.g., an operator of the vehicle) and/or control the vehicle (e.g., a speed of the vehicle), for properly aligning the track and/or other purposes. This may be useful, for example, to help prevent rapid wear or other deterioration of the track and/or for various other reasons.

Devices and systems for track tension measurement and alignment of tracked vehicles are provided. A device for measuring tension on a continuous track includes a shaft having a hollow cross section, a pin disposed at least partially through an aperture of the top end of the shaft, a compression member disposed within the inner volume of the shaft such that the pin contacts the compression member, and a base having a hollow cross section and removably attached to an outer surface of the shaft. When the base is attached to the outer surface of the shaft at a predetermined height, and the pin is depressed into the inner volume of the shaft at a predetermined distance, the distance between the top end of the pin and an end of the base is known.

In some implementations, a controller may obtain, during an event, pressure data regarding an amount of pressure of fluid associated with a component of the machine. The controller may obtain, during the event, flow data regarding a flow of the fluid associated with the component of the machine. The controller may determine, based on the pressure data and the flow data, an amount of wear of a track of the machine. The controller may perform an action based on the amount of wear of the track of the machine.

A track system includes an attachment assembly including at least one of a first pivot defining a roll pivot axis, a second pivot defining a pitch pivot axis, and a third pivot defining a yaw pivot axis of the track system. A frame assembly is disposed laterally outwardly from the attachment assembly and connected to the attachment assembly. The track system further includes at least one actuator for pivoting the frame assembly about at least one of the roll and yaw pivot axes, and at least one monitoring for determining, at least indirectly, at least one of a state of the track system and a ground surface condition. The at least one monitoring sensor is communicating with a track system controller to control the operation of the at least one actuator based on the at least one of the state of the track system and the ground surface condition.

A track system includes an attachment assembly, a frame assembly connected to the attachment assembly including at least one wheel-bearing frame member. The track system further has leading and trailing idler wheel assemblies at least indirectly connected to the at least one wheel-bearing frame member, at least one support wheel assembly at least indirectly connected to the at least one wheel-bearing frame member, an endless track extending around the leading idler wheel assembly, the trailing idler wheel assembly, and the at least one support wheel assembly. At least one monitoring sensor connected to the endless track and including an array of sensing devices communicates with a track system controller for determining, at least indirectly, at least one of a state of the track system and a ground surface condition.
