Aluminium frame bridges (cross bars):
Aluminium frame bridges can be supplied in 1 mm width sizes for inner widths from 67.0 mm – 600.0 mm .
Aluminium covers:
Aluminium covers can be supplied in 1 mm width sizes for inner widths from 43.0 mm – 600.0 mm .
Crossbar connector and frame bridge strain relief plate:
Once inner widths exceed 246 mm, we recommend the use of crossbar connectors (RSV).
Crossbar connectors cannot be used in conjunction with covers made from plastic or aluminium.
If frame bridge strain relief plates (RS-ZL) are to be used in the chain brackets, take standard inside widths into account.

FLg:
Ideal installation situation for high stresses at the limit of the max. travel parameters. In this range the chain upper run is still biased, straight or has a max. sag of 10 – 50 mm depending on the type of chain.

FLb:
Satisfactory installation position for many applications working in the lower to middle range of the max. travel parameters. Depending on the chain type, the sag of the chain upper run is > 10 – 50 mm but less than the max. sag. If the sag is greater than FLb, the application is critical and should be avoided. Please choose a more stable Murrplastik cable drag chain.

Determining the Chain Length

52.4 chain length

L = Travel distance
R = Radius
T = Pitch
E =

Length = L/2 + π × R + 2 × T + E

1 m chain = 11 x 91 mm links The fixed point of the cable drag chain should be connected in the middle of the travel distance. This arrangement gives the shortest connection between the fixed point and the moving consumer and thus the most efficient chain length.

KA 52.4 Flexible Chain Bracket

KA 52.4 Flexible Chain Bracket

This chain bracket offers universal connection options (top, bottom and front) and is attached to the ends of the chain like a side link. This allows the chain to move right up to the bracket. Each chain requires one male and one female bracket. M8 screws are used to secure the brackets in place. Extrusion-coated metal bushes with either a through-hole (-FB) or a threaded hole (-FG) ensure the permanent, high-strength transmission of even extreme forces onto the cable drag chain.

Damping elements for the side links

The damping elements in the stops facilitate a significantly quieter unrolling of the chain links. The dampers can be chosen optionally.
A reduction of the noise emission by up to 10 dB(A) comparing to the variants without the use of damping elements is possible.

MP45 damping3

Target applications (please refer to the data sheets of each energy chain model for more specifics):
• Self-supporting applications up to 7 meter travel distance
• Hanging applications up to 50 meter travel distance
• Standing applications up to 4 meter travel distance
• Sliding applications up to 50 meter travel distance

Separator

We recommend that separators be used if multiple round cables or conduits with differing diameters are to be installed. An offset configuration of the separators is advisable.

Shelving system

efk_52_1_rs

In connection with at least two shelf supports (RTT) the shelf becomes a shelving system. The additional levels prevent cables from criss-crossing and therefore destroying each other, whilst also avoiding excessive friction. Pre-assembly is not necessary as the shelving system and cabling can be assembled quickly and easily on site.

Strain relief with bow clamps

efk_52_1_bak

C-rails (cathodic dipped) for permanent integration, for accommodating the Steel Fix bow clamps in the chain brackets. The bow clamps can take up to 3 cables and are suitable for C-rails with a groove width of 11 mm. Due to the design of the trough elements, a cable preserving cable guidance is ensured. May be assembled on the inside and outside bends at both chain endings. The overall height stated is a guide only. The actual height is, amongst other things, dependent on the diameter and the quality of the cable. A safety distance of 10 mm at the fixed point above the strain relief must be kept during gliding applications.

Glide shoes / sliding blocks

Glide shoes2

In the case of energy chains, sliding blocks are used in a horizontally sliding installation mode (the tight side of the chain slides on the slack side). The sliding blocks are set onto the side links on the interior bend instead of the usual frame bridge interlocks; (no tools needed). This forces the chain to slide on the sliding blocks instead on the side links of the chain.
Depending on the application, the service life of the energy chain may be extended five-fold, by using sliding blocks.

Order No. Installation Min. radius Sliding block height
052490400300 For left side link 150 mm 4 mm
052490400302 For right side link 150 mm 4 mm

Gliding plates

slide plate2

If the installation height is restricted for a horizontal self-supported mounting position, it is recommended to turn installation of the cable drag chain by 90 degrees.
Among other factors which have to be considered, the lateral abrasion of side links is also very important. We recommend the use of special developed gliding plates to reduce the wear and to extend the service life of the cable drag chain.
We recommend a stainless steel surface for supporting a smooth movement.

Extender frame bridge

efk_bs_ma

Large-diameter conduits are routed securely by using a bracket bar (BS). This bar is installed on the frame bridges or the covers of the cable drag chain. The bracket bar can be installed on both the inside and outside bend. The bracket bar support (BSH) is used to attach the bars to PowerLine series frame bridges. Two bracket bar supports are required for each bar. On closed covers and the frame bridges of the HeavyLine series, the bracket bars are secured with screws.

Assembly instruction flexible chain bracket

efk_32_2_ka_fb_mon

Brass bushes guarantee long-lasting fastening without cold flow in the plastic.

Bracket assembly

Version KA-FB: Integrated through-hole fastened down using screw and nut.

Version KA-FG: Built-in threads allow for quick and easy on-site mounting, since a screw, including a retaining washer where necessary, is sufficient.

Rear-facing radius

efk_rue_ra
Side links with radius forward (R) and radius backward (Rü) allow for movement in two directions. This is intended for rotating movements and lowered chain brackets. Note: This type of chain has different chain links for the left or right side!

Guide channel systems for cable drag chains serve as trays for short travel distances and at the same time as guides for long travel distances. If no guide channel is used it is possible that the chain links may lay and move incorrectly. Especially for large bend radii as the side guidance does not exist. In most applications the cables/conduits enter the chain at a position central to the travel. This gives the shortest length of chain. In this case the chain is about half as long as the travel distance. If the chain is moved to the left (see illustration below) it simply rolls in the channel. If it is moved to the right, then it stacks on top of itself once the unsupported length has been exceeded. If the movement is further made into direction B the glide rail adjusts the difference in height and guarantees the minimum possible friction. This ensures the optimum free and correct running of the cable drag chain.
