Rock Picks
Pratco Quick Change Rock Pick System
Rock Pick, Hardened Intermediate Sleeve and Primary Holder
In recent years Pratco Industries has been involved in developing a Rock Pick System that delivers optimum wear life for the Iron Ore Mining industry. The key performance areas identified for Rock Pick performance include.
- High strength steel Holder body.
- Tungsten Carbide Tip design which works in conjunction with secondary wear resistance coverage.
- Secondary wear resistance by using a Tungsten Carbide weld matrix– Duratech, to limit Tip undermining and to protect Holder tools.
- Optimum Rock Pick profile design to ensure strength and rotation performance is delivered.
- Quick change Retainers to significantly reduce down time.
The full system shown can ultimately be adopted, or rock picks can be supplied initially with the quick release design to suit existing holders. A package can be supplied which includes special retainers and quick change tools.
Intermediate hardened sleeves can be used to reduce the requirement for the costly replacement of primary holder bodies. With the primary holders being welded to drums, the sacrificial intermediate sleeves can greatly reduce down time caused by cutting out and welding in new holders.
Primary weld in holders designed for the quick release rock pick and sleeves are treated with Duratech prior to fitting.
