The RL-K series – Compact design that inspires
The unique design of the knuckle boom allows the RL-K to be used in many different industries. It benefits from its high flexibility during use combined with its compact and maintenance-friendly design. When it comes to maintenance concepts, LiMain also offers significant added value on this crane. The crane can also be equipped with a pipe handling equipment. Deep-sea applications are also possible with the Heavetronic.

The RL-K 7500
The RL-K 7500 from Liebherr is a ram luffing offshore crane designed to meet the highest demands in subsea lifting. The crane is also designed for general offshore crane applications. The RL-K 7500 is equipped with Heavetronic® - a system developed by Liebherr for active heave control. This Active Heave Compensation system (AHC) enables the luffing boom crane to move loads in water depths of up to 3,600 metres below sea level. The innovative winch concept makes it possible to operate different rope types for different offshore and underwater applications. This increases the crane's flexibility enormously. The choice of rope type and diameter depends on the specific application for which the crane is to be used. Customisation to the desired configuration is simple.
