The portable external vibrator is a small but powerful concrete vibrator with a vibration unit directly connected to the motor. It is ideal for surface finishing of walls and pillars, concrete precasting, stone masonry work, and test piece manufacturing. The motor uses a robust aluminum die-cast double-insulated motor, and the body weight is light as approx 5 kg only. The EKCA is lightweight and easy to use, while the EKDA is powerful. It can be used according to the needs of the site.
The vibration unit is made of aluminum die-cast, designed to be lightweight and highly durable. Its compact size makes it easy to handle, allowing for effortless surface finishing work on pillars and walls, even in work sites with poor footing.
By attaching the exclusive holder to both the EKCA and EKDA, the effective vibration range is widened, reducing work time (Holder sold separately).
The motor case is made of aluminum die-cast, offering excellent durability and a lightweight design.
If the vibration unit wears out, it can be easily replaced. To replace the vibration unit, simply remove the four bolts that secure it between the motor and the rubber flange.
The double insulation structure is achieved through resin insulation between the armature shaft and winding core, and resin insulation between the motor case and field core. Additionally, an insulation cover is provided for the internal lead wires, ensuring a safer design.
To facilitate the cleaning of adhered concrete and mortar, a fluororesin coating has been applied to the intake cover and the bearing case of exhaust port, making it easier to remove adhered concrete.
Anti-vibration rubber has been used at the connection points between the handle and the motor case to reduce the vibration transmitting to operators.
A highly dustproof double filter has been adopted to prevent mortar from entering the casing, and the shape of exhaust port has been improved to reduce noise.
To prevent damage to the armature caused by brush wear, an auto stop brush has been adopted.
A grease cover has been provided to shorten maintenance work time, making the task easier.
