Lifting and Handling Equipment
Lifting & Handling Equipment
Robust and reliable springs for continuously moving equipment
An industrial partner for lifting and handling
For more than 60 years, Ressorts Dury has been supporting manufacturers and operators of lifting and handling equipment. Our expertise in the design and manufacture of technical springs allows us to meet the robustness, safety and durability requirements specific to this sector.
Our springs equip essential components: winches, hoists, forklifts, overhead cranes, gantry cranes, lift tables, conveyors and safety braking systems. Applications where reliability under heavy loads is an absolute requirement.
Quality standards aligned with the sector’s safety requirements
Lifting and handling equipment is subject to strict regulations in terms of safety and mechanical strength. At Ressorts Dury, we meet these requirements through:
- A complete traceability of raw materials and manufacturing processes, compliant with applicable regulations
- Rigorous controls at every stage: dimensional, load, endurance, shock and fatigue resistance
- With certified processes compliant with industrial standards (ISO 9001) and compatible with the Machinery Directive
- Complete technical documentation (material certificates, inspection reports, certificates of conformity)
Materials and treatments adapted to lifting constraints
We master the processing of a wide range of high-strength materials adapted to heavy loads and harsh industrial environments:
- Chrome-silicon alloy steels (CrSi) – high fatigue resistance and repeated dynamic load resistance
- Chrome-vanadium steels (CrV) – excellent resilience and shock resistance for mobile equipment
- Stainless steels (302, 316) – corrosion resistance for outdoor, humid or aggressive environments
- High yield strength steels – heavy-section springs for heavy and very heavy loads
Each spring benefits from adapted heat and surface treatments (shot peening, phosphating, epoxy coating, galvanizing) ensuring optimal service life against repeated loads, vibrations and harsh industrial environments.
