GP Demolition and Sorting Grabs
Robust Innovation = Low total cost of ownership.
For users who are looking for a robust demolition and sorting grab with a low construction height and a favourable own weight, Demarec has developed two new General-Purpose grabs. These grabs are meant to be mounted on wheel excavators which have to drive around a lot containing their load.
The yoke of the new General-Purpose grabs has been developed according to the Delta-box principal. The rotation motor has been installed in the yoke, which results in a very compact construction. No concessions have been made to the robustness of these grabs. The General-Purpose grabs are standard equipped with wide sealed pivot points, hardened pins, perforated shells made from Hardox, hydraulic cylinder with end damping and a load safety valve.
These grabs are also standard equipped with heavy duty side plate and straight exchangeable wear blades.
Working Safely
The application of the standard load safety valve in the grab's open/close circuit ensures safety when working with Demarec demolition and sorting grabs. For example, unsafe situations when picking up and laying dock boards are avoided.
In short, Demarec demolition and sorting grabs are by default extremely robust and fully equipped, because Demarec accepts no compromise in quality.
