Rigid Chain Technology

A simple and flexible solution

SERAPID has been designing and supplying linear motion systems for over 45 years. The SERAPID lifting and horizontal transfer systems are designed using a simple mechanical principle making it possible to transfer loads of up to several hundred tonnes using rigid chain technology (RCT).


This technology is based on unique chains which have links that lock together. When the chain is deployed it behaves like a true rigid pushing column. In the other direction, the chain unlocks in the drive housing and stores in a reduced and flexible space.

The Advantages

Rigid Chain is a true alternative to traditional traction and hydraulic solutions with many advantages:

  • simple mechanics

  • low maintenance

  • incompressible system offering precise and repeatable positioning

  • unaffected by temperature, humidity, chemical aggression and dust

  • high load capacity up to several hundred tonnes

  • long travel

  • environmentally friendly solution with no pressurised oil

  • energy efficiency system

  • regenerative drives available on all models

  • compact, low space requirement

  • easy to install and maintain

  • all installations compliant with the Lift Directive 2014/33/EU or the Machinery Directive 2006/42/EC


The SERAPID LinkLift is an electromechanical telescopic actuator specifically designed for the vertical movement of heavy loads.

It is available in a number of sizes and capacities to cater for virtually any lift requirement.

Quality System Certification

Quality is at the heart of SERAPID’s business. All the elements of SERAPID products are designed internally. The company has taken out many patents over the past 45 years. Every lift is designed by our engineers following our own rigorous internal checks and procedures.

Subcontractors are rigorously selected and regularly inspected. Materials are selected and tested to meet the required usage and environmental requirements. The production technologies used guarantee the best accuracy and performance. The rigour used in the design of our products gives an exceptional service life to our systems of up to 45 years.

Each product assembled on our shop floor is unit tested before shipping.

All our European production and processes are covered by our ISO 9001:2015 certification

Product Certification

SERAPID is committed to safety and will provide customers with the best possible solutions. In this context, SERAPID has put its lifting product (as partly completed machine) though Type Test Examination in accordance with:

  • Lifts Directive 2014/33/UE and Machinery Directive 2006/42/EC

  • Standards NF EN 81-20:2014, NF EN 81-31:2010, NF EN 41-20:2014, NF EN 81-50:2014, DIN 56950-1:2012-05
