Compact tool carrier with articulation joint
A stand-up, ride-on work vehicle adapted for multiple applications. The vehicle comprises a base unit, an articulating joint, and one of a plurality of interchangeable equipment chassis. The base unit has at least one ground supporting member, and provides power and mobility to the work vehicle. The articulation joint is supported on a front end of the base unit. An operator station extends from a back end of the base unit. Each of the plurality of chassis comprises at least one ground support member and is pivotally connected to the base unit by the articulation joint. Each of the plurality of chassis may be a dedicated equipment chassis or a universal equipment chassis. Each dedicated chassis comprises a dedicated work tool. Each universal chassis comprises an attachment surface for connection to one of a plurality of work tools. The ground supporting members may be any combination of drive wheels, trail wheels, tracks, or work tools.
1. An articulated work vehicle, comprising:
a base unit, having a front end and a back end, the base unit comprising a power unit adapted to power the work vehicle, and at least one ground drive member powered by the power unit and adapted to provide mobility to the work vehicle;
an operator station, extending from the back end of the base unit, the operator station adapted to allow operation of the vehicle while walking behind or standing on the vehicle;
an articulation joint comprising a work attachment plate and a pivot attachment, the pivot attachment operatively connected to the front end of the base unit such that the articulation joint is pivotally connected to the base unit about a substantially vertical axis to the base unit; and
an equipment chassis, removably attachable to the work attachment plate of the articulation joint comprising at least one ground support member, adapted to provide mobility and support to the equipment chassis and the base unit.
