The Lehmatic Safety Control (LSC) from Lehnhoff is an assistance system designed to prevent unintended triggering of the coupling procedure. The system is operated from the driver’s cab, giving the driver a clear overview of all coupling statuses.
Two sensors monitor the coupling process on the lock plates and the locking pin independently to ensure that the attachment is correctly in place at all times. For safety, two-finger operation is required for the unlocking function.
Should the coupling process experience a malfunction, the LSC will detect it and signal the driver. 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.
