Rung Profile & Cable Support Surface

A ladder cable tray relies on repeated rungs to carry cables across the tray width. The rung geometry affects its stiffness, available bearing surface, and connection with the side rails.

A simple flat strip can be used for lighter cable loads, while a deeper formed section can provide greater rigidity. Ribs or folded edges may also be introduced where the rung needs additional resistance to deformation.

The forming tooling can be developed for different rung cross-sections, such as:

Flat ladder rungs

Raised-center rungs

Ribbed rungs

Channel-shaped rungs

Reinforced cable tray rungs

Slotted or perforated rungs

Rung Production Parameters

Rung Length & End Preparation

The rung is normally installed between two cable tray side rails, so its finished length needs to correspond with the internal tray width and the selected connection method.

After continuous forming, the profile can be cut into individual rungs at programmed intervals. Where the assembly requires special ends, additional equipment can be integrated to perform punching, notching, flattening, or other preparation.

For example, connection holes can be positioned near both ends of the rung so that it can be fastened to the side rails. Alternatively, the end can be shaped to engage directly with a slot or opening in the rail.

Optional Processing Arrangement

Integration with Ladder-Type Cable Trays

Once cut to length, the finished rungs are assembled horizontally between the two side rails of a ladder cable tray. Their spacing can be adjusted according to the type and quantity of cables being supported.

The rung production line can therefore be matched to different tray sizes and load categories.

Power Cable Trays
Wider and stronger rungs can support heavier power cables, particularly when the tray uses relatively large support spans.

Control & Instrumentation Trays
Medium-width rungs provide regular cable support while maintaining an open structure for inspection and maintenance.

Communication Cable Systems
Lightweight rung sections can be produced for data and signal cable installations where ventilation and accessibility are important.

Industrial Cable Bridges
Heavy-gauge rung designs can be used in larger cable-support structures installed above production areas or between buildings.

The finished rungs can be supplied in different lengths to match the internal width of the tray. Production can also be organized around several standard dimensions when the manufacturer supplies multiple ladder-tray sizes.

Rung Tooling & Production Matching

The roller set is developed from the required rung cross-section and material specification. Since the component is relatively narrow, maintaining strip alignment throughout forming is important, particularly when the profile includes a small central rib or folded edge.

The following information can be used when defining the production setup:

For manufacturers producing multiple cable tray specifications, separate forming tools can be prepared for different rung sections. The cutting program can then be adjusted to produce the corresponding lengths without changing the basic production principle.

The resulting equipment is focused on one specific part of the ladder cable tray: forming consistent transverse support members that can be repeatedly cut and assembled between the tray's side rails.
