Case: EPIROC
Challenge: EPIROC drill rigs are used in everything from taking ground samples to advanced mining and mine prospecting. They are available both as separate units and as mobile units, mounted on trucks. Our challenge was to provide a secure and durable clamping force in this drilling application.
Solution: KALLER gashydraulic spring system uses gas pressure to provide the large clamping force required to hold the drilling rods in place when adding new rods for deeper drilling. When new rods are added, the hydraulic pressure is released. Instead, the gas spring locks the rod. During drilling, the gas spring system is “unlocked”. The gas spring system adds safety since it is always active even if the hydraulic pressure is lost, thus preventing that drill rods and expensive drill heads are dropped.
