Leveling System for Lift Device

A leveling system for a lift device, the leveling system comprising:

• a first actuator configured to couple to a base of the lift device;
• a second actuator configured to couple to the base;
• a third actuator configured to couple to the base;
• a fourth actuator configured to couple to the base;
• and
• a fluid circuit configured to facilitate selectively fluidly coupling the first actuator, the second actuator, the third actuator, and the fourth actuator in at least four different configurations where, in each of the at least four different configurations, two of the first actuator, the second actuator, the third actuator, and the fourth actuator are fluidly coupled together while the other two of the first actuator, the second actuator, the third actuator, and the fourth actuator are fluidly decoupled.

A lift machine comprising:

• a base having a first end, an opposing second end, a first side, and an opposing second side;
• and
• a leveling system coupled to the base, the leveling system including a first leveling assembly coupled to the first end proximate the first side, a second leveling assembly coupled to the first end proximate the opposing second side, a third leveling assembly coupled to the opposing second end proximate the first side, and a fourth leveling assembly coupled to the opposing second end proximate the opposing second side;
• wherein each of the first leveling assembly, the second leveling assembly, the third leveling assembly, and the fourth leveling assembly includes:
• an arm having a first end and a second end, the first end pivotally coupled to the base;
• a tractive element coupled to the second end of the arm;
• and
• a leveling actuator extending between the base and the arm;
• wherein the leveling actuator of the first leveling assembly is selectively fluidly couplable to the leveling actuator of one of the second leveling assembly, the third leveling assembly, or the fourth leveling assembly to selectively form a pair of fluidly coupled leveling actuators that freely pivot about a virtual pivot point;
• and
• wherein a height of the virtual pivot point is selectively controllable by removing fluid from or adding fluid to the pair of fluidly coupled leveling actuators.
