نظرة عامة على المنتج

HFJD Long Span Cable Ladder is designed for industrial, power and infrastructure projects where cable routes require increased support spacing, higher structural strength and reliable support for large cable loads.

The ladder structure consists of two reinforced longitudinal side rails connected by horizontal rungs. Compared with conventional short-span cable support systems, long span cable ladders are designed around project-specific load, span and structural requirements.

HFJD can customize the side rail profile, material thickness, ladder width, rung spacing, section length and support arrangement according to cable load and engineering drawings.

This product is part of the HFJD

صينية كابل السلم

range and can be supplied together with bends, tees, crosses, reducers, covers, splice plates and structural supports.

المزايا الرئيسية

Designed for Longer Support Spans

The reinforced ladder structure is intended for projects where greater distance between support points is required compared with conventional cable tray installations.

High Structural Strength

Side rail thickness, profile geometry, rung design and connection structure can be selected according to the required cable load and support span.

Large Cable Carrying Capacity

Long span cable ladders can be manufactured in wider and higher configurations for large power cables, control cables and instrumentation cable systems.

Excellent Cable Ventilation

The open ladder design provides free airflow around installed cables, making it suitable for power cable systems where heat dissipation is an important consideration.

Reduced Number of Support Points

When correctly designed for the required load and span, long span systems can reduce the number of intermediate support structures required along the cable route.

Project-Based Engineering

HFJD supports drawing-based manufacturing with customized dimensions, materials, surface treatments, rung spacing and structural configurations.

What Is a Long Span Cable Ladder?

A long span cable ladder is a reinforced ladder-type cable support system designed for installations requiring greater distances between structural supports.

Instead of selecting the cable ladder only by width and height, a long span system should be evaluated according to several engineering parameters:

• Total cable load
• Required support span
• Cable ladder width
• Side rail height
• سمك المادة
• Rung spacing
• بيئة التثبيت
• Concentrated loads
• Safety factor
• Project specification

HFJD can manufacture long span cable ladder systems according to project drawings and confirmed technical requirements.

Long Span vs Standard Cable Ladder

Heavy Duty Side Rail Design

The side rails are one of the most important structural components of a long span cable ladder.

Depending on project requirements, HFJD can adjust:

• Side rail height
• سمك الصلب
• Profile geometry
• Return flange structure
• Reinforcement design
• Connection hole arrangement
• Splice plate configuration

These parameters should be considered together with the cable load and required support span.

Rung Design & Cable Support

Horizontal rungs provide direct support for installed cables and connect the two longitudinal side rails.

Rung dimensions and spacing can be customized according to:

• Cable diameter
• Cable weight
• Cable cleat arrangement
• Required fixing points
• Mechanical load
• Project specifications

Cable cleats, clamps and fastening accessories can be installed on the rungs according to project requirements.

خيارات تشطيب المواد والسطح

الفولاذ المجلفن بالغمس الساخن

Hot dip galvanized steel is commonly selected for outdoor, industrial and infrastructure installations requiring enhanced corrosion protection.

View our

for additional HDG cable ladder options.

الصلب المجلفن مسبقًا

Pre-galvanized steel can be considered for indoor and general industrial applications where project requirements permit.

الفولاذ المقاوم للصدأ

Stainless steel configurations are available for environments requiring increased corrosion resistance or project-specific material performance.

الألومنيوم

Aluminum can reduce the dead weight of the cable support system while providing good corrosion resistance.

Load & Span Selection

The term “long span” should not be defined by one fixed support distance for every project. Actual allowable span depends on the complete structural configuration and cable load.

Before production, customers are encouraged to provide:

• Required support span
• Total cable weight per meter
• Ladder width
• Required side height
• Installation arrangement
• Additional concentrated loads
• Environmental conditions
• Applicable project specification

HFJD can then review the requested configuration and manufacture according to the confirmed technical requirements.
