Abstract
An improved oil drip mat assembly for use with heavy machinery having a cab and a center pin supporting the cab, such as a crane or derrick. The oil drip mat assembly includes a mat that is preferably rectangular in shape. The mat includes a central aperture and a slit positioned between the central aperture and the periphery of the mat. The slit defines a pair of edges that are flexible to be positioned around the center pin. The central aperture of the mat is therefore designed so that the edges of the slit may be adjusted so that the periphery of the central aperture can be placed around the center pin. The oil drip mat assembly also includes a plurality of eyelets surrounding the periphery of the mat and a connecting means to couple the mat to the cab such that the mat can be positioned under the cab of the machine and remain under the cab during operation of the machine to retain dispensed materials.
