A remote-operated palm tree trimming system and apparatus, configured to ascend a palm tree safely via treaded tires and trim the tree via at least one saw blade. The tires are disposed in communication with actuators which apply pressure against the trunk of the tree, ensuring that the tires maintain adequate grip to overcome gravity during ascent. A remote control, operated by user on the ground, enables control of the wheels, actuators, and saw blade, facilitating manipulation of the device to effectively trim the tree remotely, ensuring the safety of the operator.

A device for allowing work to be carried out on or about an object includes at least one gripping arrangement. The at least one gripping arrangement is configured to grip and traverse the object so as to reach a desired location on the object and to anchor the device thereto for allowing the work to be carried out.

A machine for debranching living trees can move up and down the tree autonomously via a drive mechanism and has an upper cutting unit including three blades and below it a lower cutting unit including two blades. The in total five blades are arranged so that they cover the full girth of the tree. The two blades in the lower cutting unit are horizontally offset so that their end portions can overlap. To move the machine along the tree trunk there are two belt drives which press against the tree and are both driven by a single hydraulic motor. The upper cutting unit with its three blades can move horizontally as a whole, so that when the machine is moved and encounters thicker or slightly bent parts of the tree trunk it can give way in order to prevent the bark from being damaged by the blades.

A mobile apparatus with a fluid pressure-operated implement mounted at a distal end of a boom includes a connection apparatus for selectively rotating the implement about an actuator axis at the distal end of the boom. The connection apparatus includes a rotary actuator and a pressurized fluid circuit for delivery of pressurized fluid through the rotary actuator to the implement. The pressurized fluid circuit includes channels establishing a fluidic connection axially through the rotating shaft of the rotary actuator. The pressurized fluid circuit facilitates passage of pressurized fluid through an internal, protected environment to the implement.

An automated tree cutting assembly includes a collar that may be positioned around a tree. A plurality of climbing units is movably coupled to the collar. The climbing units frictionally engage the tree thereby facilitating each of the climbing units to urge the collar around and up the tree. Each of the climbing units is positionable at selected angle with respect to the collar. Thus, each of the climbing unit units may urge the collar to travel in a spiral along the tree thereby facilitating the collar to climb upwardly and downwardly along the tree. A cutting unit is movably coupled to the collar to cut branches from the tree when the collar is positioned around the tree.
