Robust Innovation = Low total cost of ownership.

The Dedicated Demolition Line consists of the DL-series and the DR-series. Both D-series are available as combi or demolition shear and as pulveriser. The DL-series (DLC/DLD/DLP) is equipped with the standard cylinder technics with float valve. The DR-series (DRC/DRD/DRP) is equipped with the "well known" DemaPower-System with 4 pressure chamber and double acting speed valve.

Optimal jaw construction
The upper jaw has a ground tooth plate that has two front teeth which ensure outstanding penetration into the concrete during demolition. The front teeth go between the shrouds in the lower jaw, so the reinforcing steel is always separated optimally from the concrete. This all-rounder is therefore also extremely suitable for secondary demolition.

This unique cylinder technique has been developed in house at DEMAREC. The DemaPower-System has a double-action differential technique, which means the pulveriser has extremely fast cycle times. The jaw can open and close in 5 seconds. Furthermore the cylinder has 20% more power than conventionally constructed cylinders thanks to the application of 4 pressure chambers in the cylinder. This gives an enormous increase in working capacity of as much as 30%.

Twin rotation motors and filters
DEMAREC rotating pulverisers are fitted with twin rotation motors for extra rotation power as standard. The overpressure safety device in the rotation circuit ensures that no harmful forces are exerted on the machine. All models are also fitted with filters in the rotation circuit as standard.

Exchangeable wear parts
Unique to DEMAREC Dedicated Demolition Line is that the lower and upper clamping jaws are made entirely of exchangeable wear parts. This renders welding-on virtually unnecessary and prevents fatigue of the parent material. The movable jaw is fitted with an exchangeable ground tooth plate, which in turn is fitted with two exchangeable teeth. The fixed jaw is fitted with exchangeable scraping teeth. The shrouds in the fixed jaw can be not only exchanged but also turned. DEMAREC Demolition Line are therefore extremely cost-effective to use.

The DLL model is ideal for combination with hydraulic quick-change systems that involve (dis)coupling of the hose connection. A unique cylinder technique, 20% more power and extremely fast cycle times.
