E4Q energy chains

E4Q series energy chains have been developed to offer the best possible solution for unsupported and long travels. Based on the robust E4.1 energy chain standard that has been proven for over 12 years, the new series brings a long service life and a high degree of modularity.

Typical application areas: machine tools, cranes, automation systems

Product presentation extender crossbars E4Q

Design study: Clever, modular extender crossbar design E4Q

Modular extender crossbar concept with E4Q opening mechanism: adapt energy chain individually to hose diameter. Easily install without tools and replace hoses as needed.

Large hoses
The modular extender crossbar means maximum flexibility and adaptation to hose dimensions
Save assembly time: simple, fast and tool-free assembly
If a repair is required, the hose is quickly replaced by opening the crossbar on the extender crossbar

The new universal interior separation

Complete flexibility, reliability and ease of assembly in one

Depending on accessibility, choose the side from which you want to fit the shelf and see whether it is easier to access the inner or outer radius of the energy chain in order to release the crossbars. The shelves are locked in place by means of the integrated slider and automatically when the crossbar is fitted. Thanks to positive-locking, assembly is possible with virtually no force. Locking is simple and fast but the shelves are held securely in place. To unlock, release the crossbar on the inner or outer radius, depending on accessibility. The new E4Q e-chains can be opened quickly and without tools. After the crossbar has been released, the shelf can be unlocked by means of the slider and then simply pulled out.

Universal separator

Opening of the lock via integrated slider.

Shelf can be used in several layers and securely locked

When the crossbar is inserted, the lock is automatically activated.

Real-world examples

E4Q e-chain® in machine tools

E4Q e-chain® as ready-to-install energy supply in SAMAG machine tool

A 5-axis universal machine for tool and mould making is designed by Samag Machine Tools from Saalfeld/Saale. The y and z axes of the long bed machine tool have a travel of 1,000mm, and the x-axis a travel of up to 7,500mm. In the machining area, there is usually a very high load of swarf and coolants. In order to ensure high reliability, the engineers use cables from the chainflex® range (a.o. CF270 and CF 27) and E4 series energy chains (E4Q.82).

E4Q for safe and low-vibration operation of the DMF 200|8 milling machine from DMG MORI

Despite high milling speeds of up to 20,000 revolutions per minute, the DMF 200|8 milling machine from DMG MORI works with maximum accuracy in the micrometre range. This means that highly complex geometric workpieces can be machined using the five-axis milling machine. Accordingly, safe guidance of cables and hoses is essential to counteract vibrations or shocks. For this reason, the company DMG MORI opted for the E4Q energy chain series.

System E4Q/R4Q

1

Optional noise dampening (only upon request) - new type of concealed system for noise reduction. Can be retrofitted at any time. Rubber elements attached to the horizontal stop-dogs additionally dampen the impact noise of the already very quiet e-chains®. 17dB(A) less noise than 4040C series.

2

Two vertical and two horizontal stop-dogs per link provide more rigidity for the E4Q and a greater unsupported length or higher fill weight are possible. 20% more stability compared to the E4.1.

3

Crossbars (e-chain)/lid (e-tube) – the e-chain and e-tube can be opened and closed without any tools at all. Crossbars and lids/shelves lock in the side section for even greater holding forces. The e-chain/e-tube can be filled in considerably less time. 40% faster filling than E4.1.

4

Reduce weight – New findings have allowed material to be left out where it has no function with regard to the load on the e-chain . This approach has been taken inside, between the stop-dogs, and outside. Nature-inspired rounded shapes were used for the design. 10% less weight than E4.1.
