Abstract
A loader has an operator's station, comprising a cab with an operator's seat that is mounted on a pivot at the forward portions of the operator's station. An actuator is mounted between the operator's station and a loader frame to tilt the operator's station about the pivot a limited number of degrees when operating accessories mounted on a forward portion of the loader frame. The accessory is shown as a backhoe, and the forward tilting of the operator's station permits increased the downward field of view for an operator to observe the lower end of a digging arm of a backhoe at greater depths than with a fixed position operator's station.
Claims16
A cab for a work vehicle having a frame with a first support for a digging work arm at one end of the frame, a second support adjacent the one end of the frame for pivotally mounting the cab about a transverse axis, the cab including an operator's compartment with an operator support, a control for controlling the pivoting of the cab about its pivotal mounting, said control being operable to permit tilting the cab about the axis in a direction so that upper portions of the cab move upwardly and toward the one end a selected number of degrees to a selected position and to retain the cab in the selected position, wherein the selected position is a working position during use of the digging work arm.
A loader having a frame, the frame having a forward end and a rearward end, an operator's cab mounted on the frame in a first working position for operating loader arms, and pivotally mounted to the frame about a generally horizontal axis adjacent the forward end of the frame, a mounting structure on the loader for supporting a work arm for digging at the forward end of the frame, said cab being pivotable in a direction to move rear portions of the cab upwardly and an operator's seat in the cab forwardly about the pivotal mounting to a second working position for operating loader arms wherein an operator's seat is raised and moved forwardly, and a mechanical connection between the cab and the frame for retaining the cab in the second working position.
An operator's station for a work vehicle having a frame, a first support for a digging work arm at a forward end, a second support adjacent the forward end of the frame for pivotally mounting an operator's station on the frame, the operator's station having an operator seat, and a device at rear portions of the operator's station operable to hold the operator's station pivoted upwardly from a normal position so that the operator's station is moved upwardly and retained in a working position such that an operator on the operator's seat can observe an outer end of the digging arm at a greater depth below a surface supporting the frame during operation of the digging arm.
