Pipe laying machine with improved stability

Pipe-laying machine for laying pipes in the construction of gas, oil and water pipelines, the pipe-laying machine comprising a central body to which two track assemblies are mechanically connected, for its movement said central body being adapted to support a base on which at least the following are installed:

• a boom configured to move/lift/position the pipe,
• lifting means for handling the boom comprising a main winch,
• a control cab suitable to house an operator,
• wherein said boom comprises a first end pivoted on said base and a second end, connected to a control cable of said lifting means, adapted to wind/unwind itself on the main winch in order to rotate said boom carrying the second end away from/towards the ground, wherein between said base and said central body a levelling mechanism is interposed adapted to tilt said base with respect to the track assemblies, according to a longitudinal axis oriented in the direction of advancement of said track assemblies and/or according to a transverse axis orthogonal to the direction of advancement of said track assemblies wherein the levelling mechanism comprises a first rotation device rotatable about the transverse axis and a second rotation device rotatable about the longitudinal axis, wherein the levelling mechanism comprises a first and a second piston configured to rotate both the first rotation device and the second rotation device, and wherein said first and second pistons, when operated in unison, rotate the base about the transverse axis and, when operated independently of one another, rotate the base about the longitudinal axis.
