HLRU
Hook Lifting Release Unit
HLRU is a family of 14” gravitational release EMRUs (Electro
Mechanical Release Unit), energized via double solenoid
and redundant electrical circuits.
Due to its high reliability, HLRU has been extensively adopted worldwide by various platforms, both fixed and rotary wing, including PC-21, M345, AW101, AW/T129, AW149, AW159, NH90, EC135 and many others.

DESCRIPTION
For rapidity and safety of store loading operations, the
kinematics of the HLRU allows the independent closing
of the hooks which, once positively engaged, can be
simultaneously raised, thus also guaranteeing an optimal
distribution of the preload, as well as the repeatability
of the alignment, which makes unnecessary any further
harmonization procedure.
Safety pin and operating points are accessible from both sides of the unit.
HLRU is available in multiple variants, for land or naval use, and may install optional adapters, specific for non-standard stores such as torpedoes, pods, and special launchers. Moreover, based on actual mission requirements, HLRU may install arming units and single or double-connector flying harnesses, or wall mounted connectors.

Due to the growth potential embedded in its design, HRLU
is suitable for configuration upgrades in support of new
applications.
