CARRIAGE SUSPENDED CONCRETE DRILL GANG ASSEMBLY
First Claim
1. A drilling machine for boring holes in a vertically oriented surface of a slab, the drilling machine comprising:
- a drilling machine frame supported on left and right front wheels telescopingly connected to the drilling machine frame and left and right rear wheels telescopingly mounted to said drilling machine frame;
a drill gang assembly connected at a lower end of a mast which is telescopingly mounted relative to said drilling machine frame and rotatable relative to said drilling machine frame three hundred and sixty degrees about a mast axis extending vertically through said mast;
said drill gang assembly including a drill support frame supporting a plurality of drills in parallel spaced alignment; and
said left and right front wheels and said left and right rear wheels are extendable and retractable laterally relative to said drilling machine frame.

Abstract
A drilling machine for boring holes in a slab having a hole formed therein includes a main frame to which a drill gang assembly is rotatably and telescopingly mounted. The drill gang assembly includes a drill support frame supporting a plurality of drills in parallel spaced alignment. The drill gang assembly is mounted on a mast which may be rotated three hundred and sixty degrees relative to the main frame about a vertical axis up to at least one hundred and eighty degrees. The mast slides laterally relative to the main frame and the wheels supporting the main frame telescope laterally so the wheels can be supported on an adjacent lane or shoulder when the drill gang assembly is supported over a hole extending the width of a lane of a road forming by the slab.
