In order that the pneumatic piston vibrator has durable structure and anti-explosion specification, it is used as a mold vibrator for concrete placing of the tunnel site over many years. Also, this is used for years as industrial machinery in precast concrete factory and as blockade prevention of the scale hopper of the fine aggregate silo of ready mix concrete factory.

The durable body enables use in the severe site

Structure that hose coupling for air supply was attached to the durable ductile cast iron body. This structure is tough against shock from the outside, and since there is no valve in the body, and fully withstands at severe civil engineering site and the ready mix concrete factory.

Number of vibrator used can be reduced by using exclusive holder

This piston vibrator is replaced according to movement of concrete placing. So, the exclusive use plug holder is supplied as an optional. This is the convenient piston vibrator that both direct installation and installation using holder are available according to situation of the site.

Simple structure makes less troubles

Simple principle of vibration, few component parts, many actual results and reliability with few failures

Operation only by air supply

Activation and a interruption can be made only in opening and closing of air valve. General methods for use are remote control with solenoid valve, and manual operation while checking situation in the site.

Vibration power is variable by air pressure regulation

Vibration is variable by air pressure regulation in reducing valve. In order that operation suitable for object shape and weight can be made, the application extends.

Fall prevention wire is available

PSB and PLB provide mounting hole of fall prevention wire. In order to ensure the safety, we recommend you use mounting wire. (The wire is an optional)
