HS - hydraulical quickcoupler

NEW: with safety coupling Double Lock

Convenient, quick and safe locking from driver's cab at the touch of a button. The locking operation is carried out via a lockable push button or optional with the control panel Lehmatic Control (see figure). An Optical locking indicator, visible from driver's cab, indicates the right locking position of the locking pins.  A constant pressurisation and an integrated safety valve on the hydraulic cylinder ensure an always secure holding position of the lock.

NEW: All hydraulic quick couplers of the sizes HS01 / HS03 / HS03H / HS08 / HS10 / HS21 / HS25 have the new Lehnhoff Double Lock as standard. The system prevents the attachment from falling off in the event of incorrect locking, thanks to the centrally located additional claw.
