Due to the gun-drilled piston rod the PR 30 can be employed for medium-weight (DP-M) tests. An optional 20 kg weight ring is pulled over the drop weight cylinder and secured by a clamp ring to achieve the30kg drop weight mass. Like with the PR 10 the outer drop weight cylinder is powder-coated whereas the other components are galvanized, a crucial advantage when it comes to maintenance and value conservation. A transport bracket with carrying handle included in the delivery content protects the device during transport and makes for an ergonomic haulage. Two safety guiding rods allow for operating the tool from a distance of 1m. The PR 30 is CE-confirmed and fulfils the outdoor directive 2000/14/EG (noise emission).
