Abstract
A mobile pipelayer machine includes a machine chassis having a forward end, a rear end, a first side, and a second side, and a boom extending from the first side of the machine chassis. The mobile pipelayer machine also includes a movable counterweight system extending from the second side of the machine chassis, the movable counterweight system being selectively movable to change a center of gravity of the machine in at least one of a forward or a rearward direction.

A mobile pipelayer machine, comprising:
- a machine chassis having a forward end, a rear end, a first side, and a second side;
- a boom extending from the first side of the machine chassis;
- and
- a movable counterweight system extending from the second side of the machine chassis, the movable counterweight system being selectively movable to change a center of gravity of the machine in at least one of a forward or a rearward direction.
A mobile pipelayer machine, comprising:
- a machine chassis having a forward end, a rear end, a first side, and a second side;
- a boom extending from the first side of the machine chassis;
- and
- a movable counterweight system extending from the second side of the machine chassis, the movable counterweight system being selectively movable forwardly, rearwardly, and laterally towards and away from the second side of the machine chassis to change a center of gravity of the machine in a forward, rearward, and roll direction.
A method for adjusting a center of gravity of a pipelayer machine, the pipelayer machine including a chassis, a boom extending from the chassis, and a connector extending from the boom for coupling to a load, the method comprising:
- selectively moving a counterweight assembly in a forward or a rearward direction to change a forward or rearward center of gravity of the pipelayer machine.
