As a powerful partner of the maritime industry, Liebherr Components offers ideal solutions for a wide range of requirements. For many years, electric machines and control technology, gearboxes, winches, slewing bearings and hydraulic components have been successfully used in a wide range of maritime applications. These are offshore winches, ship, offshore and container cranes, propulsion systems and special equipment, for example in pipe-laying ships or jack-up platforms. Diesel-electric systems for ships complete the portfolio.
Liebherr uses advanced production technologies to manufacture its high quality, exceptionally long-serving components. All components are designed for outstanding ruggedness and withstand even extreme environmental influences like major temperature fluctuations, vibrations and maritime ambient conditions. The range is completed by a comprehensive after-sales programme that among other things includes the remanufacturing of components.
The maritime portfolio of the Liebherr Components Division on display includes a large diameter bearing with a slewing drive (either electrical or hydraulic), as well as a selection from the hydraulics portfolio showcasing a DMVA double motor as well as an axial piston pump.
Double motor DMVA 165-165
The double motor is specially designed for maritime rope winches to achieve maximum lifting capacity and performance. Due to a strong piston-sliding shoe connection and 2 small drive units back to back, it reaches a very high conversion range and, consequently, high performance and efficiency. The DMVA series provides high displacements and speeds and includes 2 motors of size 275 cm3 (up to 591kW at 430 bar) and 335 cm3 (up to 750kW at 430 bar) displacement and reach speeds up to 4.590 rpm.
Variable displacement hydraulic pump with impeller, DPVO215i
Designed for open circuit with inverse piston technology, the pump has a swivel angle of 22°, high pressure resistance as well as possible through-drive of up to 100%. Due to the integrated impeller an increase in the maximum rotation speed is possible. The DPVO215i is combinable with all common controls.
Slewing system with large diameter bearing, slewing drive and hydraulic motor
Optimally matched components of the system ensure a long service life and low lifetime costs. It is characterized by high individual load capacity, as well as easy and cost saving maintenance. It features proven coatings, materials and sealing systems for harshest environmental conditions. The system solution is not only used in maritime applications, but also in mining excavators and construction machinery
