摘要： A vibration assembly for supporting a base pallet of a concrete pipe manufacturing machine, and a method for adjusting the assembly. The assembly includes an assembly frame, at least two pallet driving blocks supported for position adjustment relative to one another on the frame, and a vibrator connected to at least one of the pallet driving blocks. The pallet driving blocks transmit force to the base pallet of the concrete pipe manufacturing machine.

摘要： Vibrational energy introduced into plastic concrete structures, such as concrete slabs, decks and similar or related concrete structures, at or near the natural resonant frequency of the liquid concrete mass, expedites the consolidation and setting of the concrete. A vibrating apparatus imparts controlled vibrations either onto the surface or beneath the surface of the concrete mass in sequential stages, the frequency of vibrations generally increasing with each subsequent stage, corresponding to the increase in the natural resonant frequency of the progressively-narrowing liquid concrete at the top of the structure. The relatively more consolidated and more dry concrete (typically near the bottom of the slab) is substantially unaffected by the non-resonant frequencies vibrations. In one modification, sensors determine the resonant frequency of the liquid concrete mass during each pass of the vibrator apparatus, and the frequency of the vibrating member is automatically adjusted, accordingly. The number of stages, the amplitude of the vibrations, the physical orientation of the vibration-producing apparatus, the time duration in each stage, is variable depending upon the physical characteristics of the concrete mass.

摘要： A concrete vibrator includes a housing, a handle, an electric motor, a flexible shaft, a vibrator head, and a battery pack. The handle extends from the housing. The electric motor is coupled to the housing. The flexible shaft has a first end coupled to the motor and an opposite, second end. The vibrator head is coupled to the second end of the shaft. The vibrator head is configured to receive torque from the motor and the shaft to cause the vibrator head to vibrate. The battery pack is coupled to a battery receptacle defined on the housing. The battery pack is configured to provide electric power to the electric motor to drive the motor and the shaft. The concrete vibrator is operable in a briefcase configuration in which the handle is used to carry the concrete vibrator with the housing supported in a horizontal orientation.
