EKD SYSTEMS, part of HELUKABEL GmbH since 2022, specializes in manufacturing energy chains since 1970. They offer a variety of steel and plastic energy chains, including custom solutions with cables, connectors, and mounting kits. Their services encompass selection, design, assembly, and commissioning.
Energy chains are available in steel and plastic. Plastic is preferred for its chemical resistance, lightweight, and cost-effectiveness, while steel is used for extreme payloads and mechanical requirements. The cross-section for wires is calculated based on motion, environmental conditions, and other factors.
- Material Selection: Plastic is preferred for general applications; steel is for high-stress conditions.
- Cross-Section Calculation: Requires clearance for each line, with specific percentages for round cables, flat cables, and hoses.
- Bending Radius: Determined by the minimum permissible bending radius of cables and hoses, installation space, and polygon oscillation.
- Energy Chain Length: Calculated based on travel distance, bending radius, and connector position.
- Pretension and Sag: Energy chains are supplied with pretension to increase free carrying lengths. Sag is influenced by load, material, and environmental conditions.
Different arrangements include normal, multiaxial, free overhang, and moved end downside, each with specific applications and limitations.
EKD offers systems like SYSTEM MARATHON for unlimited travel and gliding energy chains for specific applications. Accessories include support rolls, support rails, and carriages for enhanced performance.
- Nested Travel: Utilizes multiple energy chains with different bending radii for various cables and hoses, moved by a common driver.
- Opposite Running: Two energy chains run synchronously or independently in one line, increasing the number of moved lines without extra space.
- Gliding Arrangement: Used when the free carrying length is exceeded, requiring a trough and sliders for increased lifespan.
- Vertical Travel: Common in systems with multiple linear axes, using chains without pretension, with weight supported by the straight part of the chain.
- Vertically Hanging: Used in elevators and doors, with energy chains predominantly tensile stressed.
- Horizontal Arrangement: Chains lie on their side for space constraints or long traverses at low speeds.
- Driving Apart: Requires custom calculation of chain length based on application needs.
- Circle Arrangement: Involves circular motion with a part of the chain manufactured with an opposite bending radius, allowing rotation up to 520°.

If several lines are to be laid in one chamber, the chamber dimensions have to be restricted so that they maintain their relative positions. Even multi-layer arrangements of flat cables have always to be seperated with horizontal dividers. When using pressure hose a change in length has to be taken into account through additional clearance in the chain bow (radius), which can be achieved by a corresponding chain height (a). The distribution of the energy chain cross-section should be symmetrical in order to ensure an uniform load. In addition heavy lines are laid out close to the links to minimize...

DESIGN GUIDELINES In standard applications the fixed connector of the energy chain is arranged in the middle of the travel distance. The moving connector moves horizontally over the fixed connector between the end positions of the travel. The required length of the energy chain between the first and the last pivoting link is then determined as follows: Order infos If the fixed connector is not in the middle of the travel, the energy chain has to be extended by a displacement of x: L length of the energy chain LV length of travel R bending radius of the energy chain Design guidelines Energy chain...

The sag is due to the additional load and the weight of the energy chain. Due to the significantly lower elongation of steel (0.2% linear elongation) compared to plastics the permissible sag of the steel chains is limited lower than for plastic energy chains. On the other hand, the effect on plastic energy chains of a long-term static load with a long unsupported length of the upper strand chains will increase the sag (creeping of plastics). Elevated temperatures and humidity increases this effect. The sag of energy chains is also increased by use-wear. sag The maximum allowable sag can only...

DESIGN GUIDELINES Order infos This type is mainly used with plastic energy chain applications. As with the use of support rolls the maximum travel can be increased up to four times the free carrying length. Because of the larger permissible sagging, support rolls are not suitable for plastic energy chains. Design guidelines Raised trough Support carriage For long travel distances and high additional loads support carriages can be used with reverse travelling energy chains. The side-mounted support rolls carry the energy chain and move the support carriage. The energy chains now only face pull...

driving apart (a) With energy chains moving apart the calculation of the energy chain length does not follow the usual pattern, but be adapted to the individual requirements of the application. The circular motion is a special form of chain movement. For circle movement a part of the energy chain has to be manufactured with an opposite bending radius R2. The outer radius R3 is derived from the link height, the bending radius of the energy chain R1 and the opposite radius R2. Design guidelines Energy chains are arranged horizontally lying on their side, for example, if the space does not allow...

Order infos Design guidelines For laying in energy chains only highly flexible cables with permissible bending radii and sufficient dynamic capacity suitable. The cables have to be laid twist free to move freely lengthwise. Cable on a reel should be unrolled in the reverse winding direction and placed in the extended state in the energy chain. For intermediate storage the lines are ideally laid out straight. The material relaxation occurs in this case facilitates a twist-free installation. The distribution of the chain interior must prevent mutual interference between the wires with dividers...
