INV 3 Horizontal arrangement, gliding in the guide channel
The upper run of the cable carrier glides on the lower run or on a gliding surface of the associated guide channel.
Application: For long travel lengths which cannot be implemented as unsupported arrangements. Condition: The cable carrier must be placed in a guide channel, though!
Different cable carrier types provide the option of using glide shoes on the inner radius. These are manufactured from a special sliding and wear-resistant plastic. This allows the sliding friction factor to be reduced to a value of µ < 0.2.
For steel cable carriers, the use of these elements is mandatory to prevent gliding of “steel on steel”. The travel speed, however, should not exceed 1 m/s for glid- ing steel cable carriers. For steel cable carriers, the glide shoes are bolted onto the side band. For plastic cable carriers, the glide shoes are simply clipped on the inner radius and can therefore easily be replaced if necessary.
To reduce wear and increase the service life, we recommend using the abrasion resistant glide shoes for gliding applications. For travel speeds > 2.5 m/s, however, glide shoes should always be used.
Arrangement of the cable carrier Single-sided arrangement with lowered drive connection and reverse bending radius (standard)
The cable carrier length is always calculated with the same formula as for the unsupported arrangement:

The length of carrier in bend L B is increased by the lower drive connection and the resulting cable carrier extension. To keep this elevation of the length of carrier in bend as small as possible, chain links with reverse bending radius (RKR) are used on the drive connection as a standard. This results in a slight S-shape for the bend in the thrust end position. The respective values for L B can be found in the respective individual chapters for the cable carriers.
For the standard arrangement of the cable carrier, the drive connection is reduced for load reasons:
