Swellex (Python bolts) are water expandable rock bolt range which act as friction bolts with superior product characteristics to meet the most demanding roof support applications. The high load-bearing capacity combined with excellent elongation properties ensure safer working conditions and faster excavation cycles for low costs. Python® System binds effectively through fractures and fissures with its high load capacity. Elongation properties allow substantial movements of the rock without breaking of the bolt.
Panchvaktram Engineering offers “Jennmar make” Swellex bolts in 120kN, 160kN, 200kN and 240kN loads along with accessories. The bolts are available in 2m, 3m, 4m, 5m, 6m lengths.
