Each of the flanges has a length that is longitudinal with respect to the arm and a width that is transverse with respect to the arm and the length of each flange is between and of the length of the arm.

A work machine having a controller configured to receive a first position signal from a first boom position sensor, a second position signal from a second boom position sensor, and a load signal from the load measuring device, wherein the controller is further configured to calculate a map of hydraulic capacities within an envelope of movement for one or more of a first and a second actuators based on the first position signal, the second position signal, and the load signal, and generate a lift path of movement for the pin through at least a portion of the envelope based on the hydraulic capacities, wherein the movement envelope being smaller than the envelope.

A work machine having an intelligent mechanical linkage performance system comprises a frame and a ground-engaging mechanism, a boom assembly coupled to the frame wherein the boom assembly comprises a large boom and a dipper stick. A load measuring device is coupled to the boom assembly and configured to generate a load signal indicative of a payload. A pin is coupled to the dipper stick wherein the pin has an envelope of movement throughout which the pin is moveable by the large boom and the dipper stick. A controller is configured to receive a first position signal from a first boom position sensor, a second position signal from a second boom position sensor, and the load signal from the load measuring device. The controller is further configured to calculate a map of hydraulic capacities within the envelope of movement.

A clamp implement and a control system for controlling the clamp implement such that the clamp implement can be caused to follow motion of a bucket or other primary implement in a selected mode of operation. In another mode of operation, the claim implement can be caused to move independently of the primary implement.

A control system for an excavator, the excavator comprising a movable arm, a movable excavator thumb and a tiltrotator attached to the arm, the tiltrotator being arranged to hold an auxiliary tool which is rotatable and/or tiltable by means of the tiltrotator. The control system is arranged to control the tiltrotator to rotate and/or tilt the auxiliary tool between a plurality of first positions and at least one second position. The excavator thumb is movable between at least one rest position and a plurality of work positions. The auxiliary tool is arranged to cooperate with the excavator thumb when the auxiliary tool is positioned in any of the at least one second position and when the excavator thumb is positioned in any of the plurality of work positions. The control system comprises a first blocker arranged to block the movement of the excavator thumb when the auxiliary tool is positioned in any of the plurality of first positions.

Disclosed embodiments include implement carriers and power machines with implement carriers. In some embodiments, the implement carriers have a mounting structure having first and second mounting structure surfaces with first and second pluralities of mounting features located along the first mounting structure surfaces, respectively. Each of the second plurality of mounted features is aligned with one of the first plurality of mounting features. The mounting structure is configured to receive an implement in a first attitude and a second attitude different from the first attitude.

An attachment that is mountable to an arm of construction equipment includes a mount bracket that is removably attachable to the arm of the construction equipment. An implement is mounted to the mount bracket, where the implement is configured to perform at least one jobsite task. At least one ground support member is mounted on the attachment, and the at least one ground support member includes at least two support legs that are actuatable between a retracted position and an extended, ground-engaging position at which the at least one ground support member is able to support the attachment on the ground when the mount bracket is not attached to the arm of the construction equipment.

A utility system may include at least one moveable arm, and at least one grappling assembly connected to the moveable arm. The grappling assembly includes an upper claw, a lower claw, and fasteners to pivotally secure the lower claw to the upper claw. The upper claw includes lower grasping surfaces and coupling openings. The lower claw includes upper grasping surfaces and mating openings. Each mating opening is axially aligned with one of the coupling openings. The upper and lower claws rotate about the fasteners at first pivot axes when the fasteners are retained within first coupling openings of the upper claw and within the mating openings of the lower claw. The upper and lower claw rotate about the fasteners at different, second pivot axes when the fasteners are retained within second coupling openings of the upper claw and within the mating openings of the lower claw.

A grapple-heel rack having a frame, a grapple, and first and second angle-enabler catches. A grapple attachment (which may be or may include a universal joint) may be used to support the grapple from a nose of the frame. A mechanical grapple return system may be used to return the grapple from a non-neutral position to a neutral position. At least one method for using the grapple-heel rack.
