This concrete vibrator rental has a double-insulated 1 horsepower motor which is molded in safety yellow for visibility. Its handles are fixed in rubber motor ends that absorb the shock if the motor is dropped. It also has a super-tough Zenoy Resin housing that concrete won't adhere to. On the head, the inner core is wound from high carbon spring-wire to resist unraveling and stretching. It also has a coiled flat-wire reinforcement that keeps the shaft from kinking. It has forged eccentrics mounted on high-speed ball bearings and the industry's strongest outer casing constructed of steel flat-wire covered by alternating layers of wire mesh, fabric, and rubber.
