Improved safety and flexibility for your hydraulic quickcoupler.

Worsley Plant are pleased to introduce to the UK a new safety feature from Lehnhoff – the Lehmatic Safety Control.  Lehmatic Safety Control (LSC) is a high-quality assistance system that makes locking your hydraulically operated quickcoupler even safer, with maximum flexibility and comfort and added peace of mind.

LSC prevents unintended triggering of the coupling procedure. The system is operated from the safety of the driver’s cab, and therefore the driver always has a clear overview of all coupling statuses. Two sensors monitor the coupling process on the lock plates and the locking pin independently.  This ensures that the attachment is safely and correctly in place at all times.  Safe two-finger operation is required for the unlocking function.

Should the coupling process experience a malfunction, the LSC will automatically detect it and signal the driver.  Safety is therefore ensured at all times.  LSC also detects if the wear limits are exceeded, or if there is signal interference within the system.  Load hook mode is used for hoisting without an attachment.

Lehnhoff Quickcoupler Systems with Lehmatic Safety Control are available for almost every excavator size.
