  • Patent number: 9342093
    Abstract: The tool carrier disclosed herein has a locking device with a low degree of complexity, a low diversity of parts, and a high degree of reliability. By the completely automated locking process, the setting up of the tool on the tool carrier is considerably simplified for the operator or the driver, since neither has to leave the cabin any longer in order to lock the tool. The actuation of the setting up and holding devices by the tool during the setting up of the tool ensures that the locking device is used only if a tool is also set up. An erroneous movement of the lock into its locking position due to vibrations or by a movement of the tool carrier or the front loader without a set-up tool is effectively avoided.

The tool coupler may also have an actuator connected to move the wedge away from the hook to bias a second pin of the tool against the coupler frame, and a latch associated with the wedge. The latch may be movable between a first position at which the wedge is allowed to move away from the second pin, and a second position at which the wedge is constrained from moving away from the second pin.

  • Patent number: 8662817
    Abstract: A coupler for a backhoe or other excavator includes a frame including an upper portion and a lower portion. The upper portion is adapted to be secured to an associated backhoe or excavator arm. The lower portion includes a first hook adapted to mate releasably with a first associated attachment pin and includes a second hook adapted to mate releasably with a second associated attachment pin. First and second safety locks are movably connected to the frame and move relative to the first hook between an engaged position for capturing the first associated attachment pin in the first hook and a disengaged position for releasing the first associated attachment pin from the first hook. An actuator is adapted to move the safety locks selectively between the engaged and disengaged positions.

  • Patent number: 8585345
    Abstract: An attachment coupler includes a frame including a front hook and rear hook. A rear hook lock moves between an unlocked and a locked position relative to the rear hook. An actuator moves the rear hook lock to its unlocked and locked positions. A gravity lock moves between an engaged and a disengaged position and obstructs movement of the rear hook lock to its unlocked position when the gravity lock is engaged. A supplemental lock arm moves relative to the frame between an engaged position and a disengaged position. A secondary lock is located adjacent the front hook and includes a latch that moves between an extended and a retracted position. The latch obstructs the front hook when extended. The supplemental lock arm blocks movement of the latch from its extended position to its retracted position when the supplemental lock arm is in its engaged position. A spring urges the latch toward its extended position.

  • Patent number: 8585314
    Abstract: A safety device for quick-fastening a tool to the end of an arm including two portions (1 and 2), one of which is attached to the arm of the machine and the other of which is attached to the tool. The first portion (1) includes a cradle (3) that is insertable under the arm of the other portion (2) having an extension (5) in the form of a hook, having at least one side lug (10) that can pass through notched openings (8, 9) in the first portion (1) and in a locking plate (6). The locking plate (6) is capable of sliding on the middle portion of the first portion (1) so as to be inserted under the hook extension (5) by springs (7). The locking plate (6) is provided with an abutment member (12) that limits the return movement of the plate (6) in order to prevent the notched openings (8, 9) from coinciding.

  • Patent number: 8549775
    Abstract: A remotely operable latching system for securing an implement to a carrier mounted to a forward end of a lifting arm for pivoting about a horizontal tilt axis. The latching system is mounted to the carrier and includes a latching rod arrangement operated by an extensible and retractable linear electric motor between a retracted latching position and an extended unlatching position. A secondary latch arrangement is provided for rotating the latching rod arrangement to an arrested position preventing movement of the rod arrangement to its latching position once the latching rod is extended to its unlatching position. Movement of the rod arrangement to its arrested position is aided by a spring and by the electric motor. A microprocessor based control unit is coupled to the electric motor and acts in response to a boom height input signals to prevent operation of the motor when the boom is above a preset height.

  • Patent number: 8528239
    Abstract: A quick coupling device adapted to connect a tool to the arm of a handling equipment comprises a first support member that can be connected to an end of the arm, and a second support member that can be fixed to the tool, which members are mutually engageable as a result of a relative movement along an axis of coupling transverse to the end of arm. Each support member comprise two opposed coupling formations having a double inclination, so as to turn out to be convergent towards the axis of coupling both in the direction of mutual connection of the support members and with respect to a plane transverse to the axis of coupling. A support member includes at least one movable holding member adapted to be inserted in at least one corresponding seat of the other support member in the mutually coupled configuration, in order to mutually lock the two support members.

  • Patent number: RE44771
    Abstract: A rear-mounted implement mounting system includes semicylindrical seats open upwardly and mounted on a lower back portion of a utility vehicle chassis that receive bar members located on a facing lower part of the rear-mounted implement. The utility vehicle chassis further includes semicylindrical receivers open in a rearward direction and adjacent cylinder portions open laterally. The receivers guide cylindrical bosses, located on an upper portion of the rear-mounted implement, into alignment with the cylinder portions, when the rear-mounted implement is pivoted upwardly by extending the boom cylinder of the rear-mounted implement. Connecting pins can be slipped through the cylindrical bosses and cylinder portions to lock the rear-mounted implement to the utility vehicle chassis. An operator remaining in the vehicle cab or operator station can easily operate the mounting system.
