Robust mechanical crimping tool with ratchet. Terminals can be crimped very easily by swinging the movable handlever. The construction with the built-in-forceblocking device guaranteed a constant and exact crimping depth and therefore an excellent electrical and mechanical quality of the crimping connection. The collapsible tool head enables a quick changing of the die sets. Caused by the crimping force of 100 kN the construction offers an alternative to hydraulic operated tools.
