Profile roller e-chain®: For very high fill weights and speeds

Over 1,000 systems worldwide are in permanent use with conventional profile-roller e-chains®. Industry, in particular the crane building sector, places increasing demands on travel distances, fill weights, special and high travel speeds whilst operating quietly at the same time. igus® fulfills these requirements with the P4 system. Facilities of this type are designed by our project engineers. We'd be glad to submit an offer. You may talk to us about this.

Benefits:

The pitch for chain links with and without rollers is the same
The upper run rollers run through the lower run rollers, not overthem, as in previous designs. This avoids undesired bumps
Captive roller integrated in side plate
Long distances (up to 800 m), high additional loads (up to 30 kg/m)
For very long travel distances and high speeds up to 10 m/s travel speed
autoglide crossbars ensure safe guidance on very long travel distances
Available in 4 inner heights (32, 42, 56, 80 mm)
Modular P4 construction kit with shelving from the E4 system
Strong reduction of the driving force required for moving the energy chain to below 25%

P4 System - Very quiet running due to same pitch on all chain links. AUTO-GLIDE crossbars ensure safe guidance on very long travel distances

Safe, quiet, abrasion-resistant energy supply system on long travel distances - igus® P4 System

The low maintenance igus® P4 system allows a reliable energy supply system to be implemented on long distances up to 800 m for crane equipment or conveyor systems. The top and bottom run roll offset from one another. This means that nothing rolls over the tribo-optimized plastic rollers, but instead they roll on a continuous, wide rolling surface. The comb-like AUTO-GLIDE crossbars and the special trough system reliably guides the P4 e-chain®. Ideal for applications with high travel speeds (up to 10 m/s) and large fill weights (up to 30 kg/m)
