Concrete Vibrator Battery, Electric Concrete Vibrator with 2 x 21V Batteries and Charger, Vibration Diameter 35mm, Portable Concrete Vibrating Tool with Shaft 1.2m for Roads, Tunnels, Bridges

Powerful 600W Brushless Motor: This portable vibrating rod provides a high vibration frequency of 3,600 rpm to ensure even concrete distribution and a smooth, flat surface. It is also equipped with a 1.2m vibration rod, made of 35mm galvanized steel with a flexible inner core, which eliminates air bubbles and reduces surface defects, greatly improving concrete strength and surface fineness. The vibration rod is powered by a high-performance lithium battery, without any cables. Equipped with two 21V high capacity lithium batteries. Each fully charged battery allows 30 minutes of continuous work; together, they seamlessly cover the usual daily needs. Full charge lasts 4-5 hours. It has overpressure, overheating, overload, deep discharge and overload protection functions. This concrete vibrator is used to compact concrete in construction and renovation sites, to increase deaeration and improve compaction. Suitable for various scenarios. Suitable for housing construction, road and bridge construction, prefabricated elements, tunnel projects and other concrete work. Meets vibration requirements for beams, posts, slabs, walls, etc. The cordless concrete vibrator is equipped with an ergonomic non-slip handle and self-locking switch that allows continuous operation for long working hours. This reduces workload and reduces finger fatigue. Cast aluminum gear housing, sturdy and durable, optimized air output for fast heat dissipation. Align the hose horizontally to the motor. When you stand facing the motor, tighten it by turning it to the left (counterclockwise). After switching on, the motor runs quickly, but the front end of the hose may not vibrate visibly – this is normal. Lightly tap the metal head on the side against the floor or formwork to trigger vibration.
