Liebherr Hydraulic Hoses and Hose Kits
Liebherr-Australia Hose Production has been manufacturing high pressure hose assemblies in the Adelaide head office complex since 1999, and is situated in our 12,000m2 state-of-the-art national distribution centre facility with a dedicated assembly production team.
Hose Production Capabilities
The facility has dedicated lines for its low/medium and high pressure manufacturing, feeding into the 8 inch diameter, 450 tonne crimp force press; with the additional capability to test hose assemblies up to 1,500 bar in the 5m dual-bed test bench. This testing capability supports stringent Liebherr-Australia and MDG 41 requirements.

Design and Testing
Liebherr-Australia designs, develops and carries out rigorous testing in our Adelaide manufacturing facility. Initial designs are developed in-house and then tested at our research facilities, with all fittings designed and developed in accordance with relevant international standards.
Hose assembly designs are tested and accredited to internationally recognised specifications. We test assemblies at up to 1500 bar (14500psi), which far exceed normal operating pressures. The machines test up to 2” 6 wire hose assemblies.
Static testing is carried out on individual hose assemblies prior to supply. These are tested to the relevant pressure specific to the hose type. Test certificates are available upon request.
All hoses are designed and manufactured to suit specified applications; our custom built hoses take into account the following factors:
- Material being transported
- Wear resistance
- Exposure factors such as UV and Ozone
- Product temperature
- Flange orientation
- Chemical resistance
Quality– ISO 9001 and MDG41
Liebherr-Mining Operations in Adelaide achieved successful certification by an independent certification body (BSI) to ISO9001:2008 at the end of 2015 and was registered as a certified company in February 2016, which included the hydraulic hose assembly operations. This certification reinforces the Liebherr Core Value of ‘Quality in everything we do’, and provides added value for our customers.
During the introduction of ISO9001, the hydraulic hose assembly operations also adopted the requirements of MDG41 in a comprehensive, risk-based and systematic manner. The hose assembly operations and associated systems form part of the stringent independent internal process and quality audit process managed by the quality assurance department, with the aim of ensuring technical and work standard compliance.
The Hose Manufacturing Department is structured to have a systematic risk-based approach to the assembly operations, with control points built into ensure the quality at key stages with records to demonstrate. All materials received and used in the assembly operations are supplied by the OEM factories. A rigorous supplier quality management process in place to ensure Liebherr-Australia receives raw material that comply to the Liebherr, customer and other international technical requirements before being used for assembly operations.
MDG41 22.214.171.124 - Quality Plan
The process of hose manufacture, from raw materials shall comply with ISO Standards 9001, 9002 and shall be batch tested for conformance and recorded. The hose end assembly manufacture should hold third party accreditation.
Stringent quality assurance process for raw material used and is fully traceable to the source
Inspection and Test Plans (ITP) show each step of the assembly process, with the various control points and records for each
MDG41 126.96.36.199 - Competence
Persons fabricating hose assemblies shall be competent and trained in the proper use of equipment, materials, assembly procedures and testing. People should be assessed in their competence for hose assembly and the assessment should be recorded.
Assembly operations team are OEM factory trained and able to work effectively in all areas of the assembly process
MDG41 188.8.131.52 - Cleaning & Packaging
Hose assemblies should be supplied free from water, debris, metal shavings, dirt or any other foreign material. A cleaning projectile should be shot through the hose assembly in both directions. End connections should be sealed and capped to maintain cleanliness.
Hose assemblies should be packaged such that external abuse during shipping, handling and storage does not damage the hose or fittings.
All hoses are cleaned and packaged to ensure peace of mind
