Digging machines, in particular, hydraulic excavators, are used in a wide variety of construction sites. For example, a user may control the digging machine to operate a bucket at an end of a boom attached to the machine to excavate dirt, rocks, clay, sand, asphalt, cement, etc. In most digging machines, the operator is positioned within an operator cab positioned on a platform above the undercarriage of the digging machine. The operator cab is typically adjacent to the connection of the boom to the platform. As such, the boom may obscure the operator's visibility around the machine and into the excavation site. The operator is also off-center from the boom and the bucket, which may impair the operator's ability to operate the boom and bucket. Other elements of the machine positioned on the platform may interfere with or limit the rotation of the excavator boom and/or the operator cab. Additionally, if the digging machine includes cameras, sensors, or other electronic units that may be used in automated procedures, the electronic units must adjust the calculations or otherwise account for the boom and bucket being off-center from a longitudinal centerline of the machine.
U.S. Pat. No. 9,510,522, issued to Yrjänä et al. on Dec. 6, 2016 (“the '522 patent”), describes a forestry machine with a boom structure that includes a branched or fork-like structure. The boom structure of the '522 patent includes branches on left and right sides of the cab. The cab of the '522 patent is positioned in the longitudinal middle of the work machine, which may improve the visibility of the worksite from the cab. The cab of the '522 patent rotates or pivots with the boom to perform various operations at the worksite. However, the cab of the '522 is positioned in a central position along the longitudinal length of the frame of the machine, which does not rotate with the boom or cab structure. The cab and boom of the '522 may not provide for sufficient operator visibility and maneuverability for some applications. The cab and boom configurations of the present disclosure may solve one or more of the problems set forth above and/or other problems in the art. The scope of the current disclosure, however, is defined by the attached claims, and not by the ability to solve any specific problem.
