Profile: J. V. Engineering is a manufacturer, supplier, and exporter of construction equipment and allied products. Our products include double beam surface vibrator, concrete trolley, groove cutting machine, vacuum de-watering pump, power trowell and flootor. Our double beam surface vibrator is used for obtaining properly leveled and compacted concrete surface. These vibrators can effectively vibrate and compact concrete up to a depth of 150 mm depending on concrete consistency, and can also be provided with frequency adjustment to suit the concrete. Double beam surface vibrator consists of two main parts: beam unit and vibrator unit for electric drive. The main components of the beam unit are two hollow special alloy-light weight extruded profiles, while the vibrator unit consists of a fractional horse power motor designed to withstand continuous vibrations. The amplitudes of vibrations can be changed in steps of 10% from 30 to 100%.
