Bossprop 200mm
The BossProp 200mm is a precision-engineered elongate comprising a steel tube and two types of timber—Saligna for load-bearing strength and Pine for yielding properties—integrated with a pre-stress unit. It has a load-carrying capacity of approximately 30–40 tons and a yield range of 250mm to 500mm.
It has a load-carrying capacity of approximately 30–40 tons and a yield range of 250mm to 500mm. The design incorporates ‘softer’ timber, allowing the prop to maintain a constant load during use.
This consistent performance improves hanging wall stability and enhances miner safety underground. The BossProp weighs an average of 40–45 kg.
