This product is used for the following applications:

• Concrete placement in general
• Test piece manufacturing

• Features

  The handy held hard shaft vibrator is a small, powerful vibrator consisting of a vibrating unit connected directly to a motor. Suited mainly for secondary concrete products, along with stone masonry. test piece manufacture, and other purposes. The product comes in a long lineup of models, with various vibrator diameters of 23 mm, 25 mm, 28 mm, and 32 mm, with diverse vibrating unit lengths. Equipped with a robust double-insulated sealed motor made of die-cast aluminum, this handy vibrator is lightweight, coming in a variety of models, which makes it easy to operate on a wide variation of worksites.

  Lightweight and highly operable

  The handy hard shaft series weigh about 5 kg and are lightweight and user-friendly on a standard basis. They vary greatly in length and diameter. Because of their offerings that can be used according to different work environments, they prove to be very easily operable.

  The motor case is made of robust die-cast aluminum

  The handy held vibrator series of motor cases are made of lightweight, strong die-cast aluminum. Robustly designed to meet the particular worksite operating conditions, these vibrators can be used with peace of mind.

  

  The vibrating unit is easy to replace

  If the vibrating body is worn, it is easy to replace. To replace it, you have only to detach the four bolts fastening the rubber damper of the vibrating body on the motor.

  

  A long lineup

  The vibrating body of the handy held hard shaft series comes in a variety of diameters and lengths, which allows you to select the appropriate model according to the condition of the particular compaction worksite with concrete and to the mold dimensions, depth, rebar arrangement, and freshly mixed concrete. The vibrating body of the electrode series comes in various lengths: 23 mm, 25 mm, 28 mm, and 32 mm.

  

  A double-insulated structure requiring no grounding

  The handy held series of motor cases are safe, user-friendly motors with a robust die-cast aluminum body having a double-insulated structure requiring no grounding. The armature shaft is insulated from the winding core by using resin, and the motor case is insulated from the field core by using resin, thereby ensuring double insulation. That insulation is further reinforced by a resin cover on the inner lead wires.

  

  Concrete adherents are easy to remove

  On worksites with handy held vibrators, concrete mortar adherents close up much of the air suction and exhaust ports of the motor. Removal of hardened mortar is also hard to perform. The suction port cover and bearing case are therefore coated with fluororesin to enable the concrete to be easily cleaned, resulting in higher maintainability.

  Excellent rubber characteristics

  Handy hard shaft, handy punches, handy scrapers, handy wall concreting, and handy tamper series are equipped with rubber dampers having damping performance that meets the particular uses. This makes this series of vibrators easy on the worker’s hands and user-friendly.

  

  A motor handle with a double-damped structure

  E motors employed in the handy held vibrator series are each equipped with four small rubber dampers on the handheld handle and the motor frame. The result is that the handy baby flexible series are attenuated in vibration in the flexible hose, while the handy hard shaft, handy punch, handy scraper, handy wall-concreting, and handy tamper series are of a double-damped structure together with the rubber dampers on the motor and the vibrating unit mounts. These are therefore designed to be easy on the workers’ hands.

  

  Control on motor exhaust sound

  The handy held vibrator series of vibrators control motor noise, thereby being easy on the worksite environment. The exhaust sound from the cooling fin of the series of motors running fast is controlled as far as possible by specially shaping the cooling fin and exhaust port. (5 dB down from our earlier models)

  

  The motor suction port equipped with a dustproof filter

  On worksites with handy held vibrators in severe dusty operating environments, it is also much feared that some fine aggregate from the dry concrete mortar may go into the motor. The suction port of the motor is therefore equipped with a dual filter. The filter is employed to minimize the incidence of the motor from accidentally being locked in revolution due to the ingress of small pebbles or something similar.

  

  A shutoff brush employed

  The motor is equipped with a shutoff brush to protect against burns. The motor is prevented from burns by employing a structure that stops the motor by shutting down the power before the brush completely reaches its wear limit in order to prevent imperfect contact with the armature and scratches in the commutator due to brush wear.
