Articulated boom telehandler

A telehandler, comprising:

• a frame assembly;
• a plurality of tractive elements rotatably coupled to the frame assembly;
• a boom assembly, comprising:
• a base boom section having a proximal end pivotably coupled to the frame assembly and a distal end opposite the proximal end;
• and
• a telescoping assembly having a proximal end pivotably coupled to the base boom section and a distal end configured to be coupled to an implement, wherein the telescoping assembly includes at least two telescoping boom sections slidably coupled to one another;
• and
• a controller configured to selectively reconfigure the boom assembly between a high lift mode and a high capacity mode, wherein the base boom section is free to rotate relative to the frame assembly when the boom assembly is in the high lift mode, wherein the controller is configured to limit movement of the base boom section when the boom assembly is in the high capacity mode, and wherein the telescoping assembly is free to rotate relative to the frame assembly when the boom assembly is in the high capacity mode.

A boom assembly for a telehandler, comprising:

• an intermediate boom section;
• a base boom section having:
• a proximal end configured to be pivotably coupled to a frame assembly of the telehandler;
• and
• a distal end opposite the proximal end of the base boom section, wherein the distal end of the base boom section is pivotably coupled to the intermediate boom section such that the base boom section rotates about a first axis relative to the intermediate boom section;
• an upper boom section having:
• a proximal end pivotably coupled to the intermediate boom section such that the upper boom section rotates about a second axis relative to the intermediate boom section, wherein the first axis is offset from the second axis;
• and
• a distal end opposite the proximal end of the upper boom section;
• an implement coupled to the distal end of the upper boom section;
• and
• an actuator selectively reconfigurable between a locked configuration and an unlocked configuration, wherein the boom assembly is configured to move freely when the actuator is in the unlocked configuration, and wherein the actuator includes a pin positioned to engage the intermediate boom section to prevent movement of the intermediate boom section relative to the frame assembly when the actuator is in the locked configuration.
