  • Patent number: 8985837
    Abstract: A concrete vibrator for a hopper which feeds concrete to a slip form is mounted to the outer surface of the hopper wall. The vibrator is fixed to the end of a tube which extends into the hopper through a hole in the hopper wall. A rubber isolator molded on the tube is clamped between flanges one of which is welded to the outer surface of the hopper wall.

  • Publication number: 20120092948
    Abstract: A concrete vibrator system with a constant speed motor, one of a set of vibrator heads with different load characteristics, and one of a set of drive shafts connecting the motor output shaft with one of the vibrator heads. A speed control circuit senses motor shaft speed and maintains constant speed. The motor is cooled by a fan mounted on the motor rotor which draws air through an inlet and exhausts air through an outlet both of which face downwardly when the motor is in use. Rain or other liquids are prevented from reaching the motor.

  • Patent number: 6109111
    Abstract: In a concrete finishing machine having a plurality of vibrators to be at least partially submerged in concrete or other semi-fluid viscous material for vibration thereof, a monitor is provided for displaying and/or recording operational parameters of the plurality of vibrators. The monitor includes a display, responsive to signals generated by sensors operatively associated with the plurality of vibrators, for providing a visual indication of operating parameters for the plurality of vibrators, and a recording device receiving the signals generated by sensors operatively associated with the plurality of vibrators and recording the operating parameters for the plurality of vibrators.

  • Patent number: 5992238
    Abstract: In a vibrator intending to be at least partially submerged in concrete or semi-fluid or viscous material for vibration thereof, the vibrator having a housing open at one end and enclosing a rotating eccentric weight assembly, and a motor attached to the housing open end driving the rotating eccentric weight, a vibration speed sensor includes a magnetic pick-up disposed in a port in an end wall of the motor and adjacent an end of a gear/gear shaft of magnetic material in said motor, wherein the gear/gear shaft has a discontinuity adjacent the magnetic pick-up, whereby rotation of the gear/gear shaft is sensed by the magnetic pick-up. The motor includes hydraulic inlet and outlet ports in the motor end wall with the magnetic pickup port disposed adjacent thereto. An output cable is connected to the magnetic pick-up and extends in parallel with hydraulic hoses attached to the hydraulic inlet and outlet ports.

  • Patent number: 5564824
    Abstract: A vibrator for use in concrete or other semi-fluid or viscous material is provided with a casing having an open chamber therein, a cap detachably connected to the casing, a cantilevered stub shaft extended into the chamber from the cap, a bearing on the stub shaft, and an eccentric weight mounted on the bearing for rotation about an axis and the stub shaft for generating vibrations.
