Constant hangers are used for piping and related components where higher levels of vertical travel occur. Their job is to transfer the working load over the whole travel area while keeping it constant, i.e. without any considerable deviations. The functional precision of the constant hangers is decisive for favourable long term behaviour of the components involved.

Mode of operation

The mode of operation is based on the lever principle, according to which variable spring forces are transformed into a constant support force by way of lever mechanics. This allows for a lower installation height compared to the conventional LISEGA constant hanger.

Scope of performance


0.21kN to 100kN / 29.23 lbf to 112,404.47 lbf

Travel range

up to 300 mm / 11.81 in

LISEGA Benefits

Users of LISEGA constant hangers benefit from many special features:

360 Degree view
  • front view
  • rear view
    • Name plate contains complete technical specifications.

    • Load scale with permanent marking of adjustment load.

    • Principle-based constancy by way of a special mode of operation.

    • Pre-relaxed springs eliminate any significant loss of load-bearing capacity.

    • Directly readable travel scale with marking for hot/cold load positions.

    • Torque-free load application due to a single suspension point.

    • Reduced friction due to minimised number of bearing points.

    • Blocking is adjustable to practically any travel position through fine-tooth notching.

    • Turnbuckle function allows re-adjustment of pipe installation position.

Product Preview
  • Symmetrical design ensures direct flow of forces through axis of symmetry.
  • Favourable power-weight ratios for reduced installation loads.
  • Arranged by load groups and travel ranges to simplify selection (modular system).
  • Consistent functional behaviour due to high-quality corrosion protection and maintenance-free, chemically nickel-plated finishes.
  • Readily adaptable to the installation situation due to suitable designs and standardised accessories.
  • Double load-tube guiding of constant supports for transmission of side loads.
  • Secure connection of load chains due to load- and connection-compatible modular components.

Pipe supports and services

A complete product portfolio with tens of thousands of components covers all support situations, operational loads, temperatures and travel ranges normally experienced in piping systems in industrial plant construction. LISEGA’s modular system provides the corresponding basis. All components have a connection compatible with their load groups.
