  • Publication number: 20100028080
    Abstract: A trench compactor assembly for use with a piece of equipment, the trench compactor assembly comprises: a compactor wheel, a frame assembly, a compactor mount, and an exciter. The frame assembly comprises one or more primary frame members and one or more extension members. The one or more primary frame members have a first end disposed adjacent the rotational axis of the compactor wheel, a second end spaced apart from the peripheral compaction surface of the compactor wheel, and a length greater than the radius of the compactor wheel extending between the first end and the second end. The exciter is disposed adjacent the second end of the one or more primary frame members such that the exciter is substantially aligned with the first and second ends of the primary frame members and the rotational axis of the compactor wheel. The exciter is selectively connected to a hydraulic system of the piece of equipment such that the exciter is further selectively actuated to generate vibrations.

  • Publication number: 20080205986
    Abstract: A vibrating trench compactor apparatus including a first frame, a second frame, and a compactor wheel. The first frame has an adapter plate connectable to a vehicle and a first arm and second arm extending from the adapter plate. A plurality of vibration dampening members are disposed through each arm. The second frame has a motor mounting plate and a first leg and a second leg extending from the motor mounting plate where the first and second leg are interconnected to the vibration dampening members. The compactor wheel is rotatably connected to the first leg and the second leg and a vibration motor is mounted to the motor mounting plate of the second frame for imparting vibrational movement to the compactor wheel via the second frame.
