Abstract

A work machine includes a first chassis having a longitudinally extending spine with front and rear axles and wheels, and a second chassis having a base with an engine module and an operator'"'"'s cab. The operator'"'"'s cab and engine module are spaced apart to form a gap therebetween, with the gap adapted to accommodate the spine of the first chassis for assembling the first and second chassis together. In view of the modular construction, the second chassis can be attached to a number of different first chassis to provide versatility.

Claims

1. A work machine, comprising:

a first chassis having a longitudinally extending spine and front and rear axles and wheels;

a separate and distinct second chassis having a base, said base having first and second side portions,

an operator'"'"'s cab adapted to be mounted to said first side portion of said base;

an engine adapted to be mounted to said second side portion of said base, said engine being spaced from said cab with said engine, cab, and base defining a u-shaped gap; and

said spine of said first chassis being adapted to be positioned within said u-shaped gap and in contact with said base, and said first chassis being adapted to be connected to said second chassis.

2. A work machine, as set forth in claim 1, wherein said first chassis is releaseably connected to said second chassis by a plurality of threaded fasteners.

3. A work machine, as set forth in claim 1, including a telescopic boom, outriggers, ballast weight, and a plurality of hydraulic cylinders mounted to with said first chassis, and further including a plurality of hydraulic valves, hydraulic pumps and filters mounted to said second side portion of said base, and a fuel tank and a hydraulic tank mounted to said first side of said base.

4. A work machine, as set forth in claim 1, including a drive transmission and first and second drive shafts connected to said second chassis, said first drive shaft being adapted to be coupled to said front axle and said second drive shaft being adapted to be coupled to said rear axle, said first and second drive shafts completing a drive between said drive transmission and said wheels.

5. A work machine, as set forth in claim 4, wherein said first and second drive shafts are positioned below said second base.

6. A work machine, as set forth in claim 1, including a plurality of cylindrical sleeves connected to said first chassis and a plurality of stiffening plates connected to said second chassis, and further including a plurality of threaded fasteners adapted to penetrate said sleeves and said plates and connect said first chassis to said second chassis.
