The Penny Duke Prop is a self-contained hydraulic mining prop, unique in the European market, designed for safe, consistent and reliable operation in arduous conditions. It can be carried by one person and positioned and set in place quickly using basic tools to provide full-caving, long-wall support and resistance to convergence. The Penny Duke Prop is available in 15, 20 and 25 tonne yielding capacity versions. Each unit is fully-enclosed for protection with separate valves for setting, release and yield to promote safety, simplify operation and ensure consistent performance and reliability. More than five million Duke Props have been sold and it is believed to be the most widely used prop in the global mining industry.
The Penny Gun Set Prop offers a consistent yield characteristic up to 40 tonne loading and is designed for applications where a higher support density is required. The use of the gun set (also known as gunset) mechanism allows the prop to operate in the 600 to 2500mm setting range. A suitable source of hydraulic pressure and appropriate hose system is required to power the Penny Gun Set Prop. Each unit is designed and constructed for robust, durable and reliable operation.
The Penny Power Prop provides safe, lightweight, temporary support in thicker seams between 2200 and 3500mm. The prop yields at 11 tonnes and is powered by hydraulic pressure from any available oil or water source including the mine’s underground water supply or even the fire-fighting range. A remote control facility ensures the Penny Power Prop can be deployed while the operator is kept away from the immediate unsupported roof area and is less at risk from falling material. Operating costs and waste are reduced significantly because water rather than expensive oil is released on to the floor when the prop is lowered. The use of water also eliminates risks associated with oil such as slipping.
Each prop can be supplied with a range of extensions, friction tops, channel tops, prong tops and other spares to enable deployment in any mining and roof support application.
