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

efk_bekl

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

Length = L/2 + π × R + 2 × T + E

1 m chain = 13 x 77 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.

Chain bracket flexible

Chain bracket flexible

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. M6 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.

There are several options regarding the chain bracket. The fixed-point bracket (inside/bottom) and the moving end bracket (inside/top) are supplied as standard. However, any other combination can be supplied upon request. The chain bracket is fastened at the end like a side link. This enables the chain to move right up to the bracket. Each chain requires two chain brackets. The brackets should be fastened with M6 screws.

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.

Rear-facing radius

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.

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.
