Quick couplers with Front Pin Lock

Front Pin Lock Steelwrist 900x600

Front Pin Lock - FPL

Safe when changing work tools

Every day buckets are dropped on job sites! Most often without casualties, but sometimes the result is a serious accident. Work safety is paramount, that is why we in 2012 developed our patented Front Pin Lock technology that enhances safety on quick couplers. The Front Pin Lock (FPL) system minimizes the risk of a dropped bucket or work tool as long as the front pin is connected. The front pin is easily visible from the cab by the operator.

Front Pin Lock is designed for high durability and tough environments. The system is not dependent on sensors and works equally well with all types of excavators and control systems, and is compliant with ISO13031.
