LINKS INTERMEDIATES


Intermediate links are designed to increase and regulate the length of the suspension, the transition from one type of connection to another, change the location of the axis swivel, coupling fittings, designed for different loads.
Intermediate links can implement:

- Extension of isolating hangers (links types PR, 2PR, PRT);
- Change of plane pivotally (links type PRV);
- Adjustment of the radial rocker types 3KL, 5KL, 8KL (links 2PRR type);
- Ease of installation (such as links PTM);
- Switch connection for the various failure load (links transition PRT, PRC;
- The transition from the compound "finger-eye" to the chain coupling (PCR type units).
