  • Drilling apparatus mounted on wheels, with articulated chassis
    Patent number: 6152244
    Abstract: A mobile drilling apparatus has a front chassis with two wheels, and a rear chassis with two wheels, which are joined together by an intermediate articulation about a vertical axis. To improve the lateral stability when turning, the front chassis is extended backward behind the intermediate axis of articulation and above a portion of the rear chassis. The front chassis thus extends support, in addition to the drilling arm or arms and the driving and work station of some of the electrical and/or hydraulic equipment of the apparatus. In a converse arrangement, the rear chassis is extended forward, in front of the axis of articulation and over a portion of the front chassis.
