Cast Iron Expansion Shell Expansion Leaves For Mining Roof Support Systems
Product Details
Application
Expansion shell rock bolt anchors come in a wide variety of styles but the basic principle of operation is the same in all of these anchors. The components of a typical expansion shell anchor are a tapered cone with an internal thread and a pair of wedges held in place by a bail. The cone is screwed onto the threaded end of the bolt and the entire assembly is inserted into the hole that has been drilled to receive the rockbolt. The length of the hole should be at least 100 mm longer than the bolt otherwise the bail will be dislodged by being forced against the end of the hole. Once the assembly is in place, a sharp pull on the end of the bolt will seat the anchor. Tightening the bolt will force the cone further into the wedge thereby increasing the anchor force.
