A field-configurable apparatus for different aerial applications is provided. The field-configurable apparatus attaches to an aerial boom on a mobile carrier. The apparatus can perform rapid semi-precise cutting of vegetation. Additionally, the apparatus can perform more precise trimming of one or more areas (e.g., limbs) and optionally use a limb clamp to prevent cut limbs/vegetation from arbitrarily falling on objects below the cutting area. Still further, the apparatus can have a grapple or similar device attached to the end of the boom for use in relocating debris or for loading debris. Other industrial applications are also possible (e.g., commercial water blasting, deicing of planes, etc.). In each configuration, the apparatus comprises one or more rotatable or pivoting couplings to allow for rotation about one or more axis and therefore allow precise manipulation of an aerial tool assembly from an operator in the vehicle or on the ground.

A system for a hydraulic tree branch shear including a skid-steer loader and a shear assembly. The skid-steer loader of the system for a hydraulic tree branch shear may be an existing skid-steer loader adapter to have the shear assembly attached thereon. The shear assembly is powered by a hydraulic attachment that is configured to be powered from the skid-steer loader. Additionally, the controls for the shear assembly are configured to be attached to the existing controls of the skid-steer loader. The shear assembly is mounted to the skid-steer loader and allows a user to cut down hard to reach tree branches from the comfort of the skid-steer loader. Furthermore, the use of the skid steer loader provides a user protection from having tree branches falling on the user's head.

A modular structure for an energy wood grapple has at least two opposite jaws (31, 32) that are configured to press vertical trees against a blade, thereby cutting the tree. The remaining portion is held by the jaws (31, 32) against a body (10) of the energy wood grapple. The modular structure comprises two frame plates at opposite sides of the body (10), attached detachably, for example by bolts (23). The jaws (31, 32) are attached between the opposite frame plates detachably, to axles that provide a pivot for the jaws (31, 32).

An articulated boom having two limbs, wherein at least one of the limbs includes a first section, a second section and an electrically insulating connecting piece which connects the first section to the second section and which is rigidly connected to the first section and to the second section. The connecting piece includes glass fibers which are cast with a plastic matrix.

A tree saw attachment for a modular landscape trimmer is disclosed. In one embodiment, the tree saw attachment is provided with a drive unit having a drive shaft operably connectable to a motive source and a transmission operably connected to the drive shaft. An anvil is connected to and extending from an output side of the transmission of the drive unit, and a blade is connected to the output shaft of the transmission. The blade has an arcuate outer peripheral edge with teeth formed along a portion thereof forming a cutting edge so as the output shaft is rotated, the distance between the cutting edge and a central axis of the output shaft increases until the blade has substantially completed one rotation. Rotation of the blade causes the blade to move transversely with respect to the anvil to engage and cut material positioned between the blade and the anvil.

A gripper having at least two gripper arms movably arranged in a pincer-like manner on a base part and a cutting device for material to be cut for attachment to a processing machine, wherein the cutting device is formed by a cutting plate, which is movable by a piston-cylinder unit from an active position, in which the cutting plate projects into a receiving space for the material to be cut enclosed by the gripper arms, into an inactive position, in which the cutting plate is retracted in the base part. The retractable and extendable piston rod of the piston-cylinder unit is connected to the cutting plate via a driver pin which, in the active position of the cutting plate, rests against an abutment of the base part when the cutting plate is loaded.
