Steelwrist symmetrical quick couplers are unique. No other manufacturer cast the entire quick coupler in steel and includes front pin locking as standard for maximum safety. We also include Expander pins so that we create a truss structure taking up the lateral forces that comes when you start using a tiltrotator.
The advantage of casting in steel is that materials can be optimized where needed (for example, contact surfaces to pins in order to minimize the preassure per square mm) and eliminate material where it is not needed. The result is an unrivaled relation between strength and weight.
With Front Pin Lock you are safe during tool changes regardless of control system, the size and age of your excavator. A simple mechanical solution that protects against the most common risk, i e that you by misstake connect the rear pin in the wrong way without noticing it.
