Igus Cable Drag Chain/Cable Carrier/Energy Chain

18 Series small plastic bridge type cable drag chain

Structure:
Drag chain looks like tank chain, consisting of many unit rotating-freely links. Unit link consists of left -and-right link plate and up-and-down cover plate. Each drag can be easily opened and installed, no need threading, just put the electric cable, oil tube, air pipe, water pipe and others into drag chain after opening the cover plate.
Same series drag chain have same inner height, outer height and pitch, but inner width bending radius can have different choice.
Features:
The individual chain links can be connected by a snap connection enabling them to be joined to form a chain of any required length.
Bridge type cable chain can be supplied with or without seperator to guide the cables.
This cable chain can be supplied with the lid hinges open, and various width are available for installation as long as it is the same series with the left-and-right link plate. The internal height will remain the same.
Due to the rigid jointed structure, the chain joint lock in the opposite direction. Enclosed wire can't bend more than fixed bending angles.
The left-and-right link plate can be added with button of various color for more beautiful appearance.
Enclosed type cable chain can provide protection from dirt and debris, such as woodchips or metal shavings.
Material: Reinforced nylon(Flame retardant)
Operating temperature: -40º C(-40F)~250º C(482F)

Chain connection and Installation:
1. Drag chains can, apart from for normal horizontal movements, also be used for vertical, circular and combined horizontal/vertical movements. If the cross section is too small for the cables, it is possible to divide the cables between a number of chains arranged side by side or opposite to each other.
2. The fixed point connection should be laid in the middle of the travel length. This arrangement yields the shortest connection between the fixed point and the mobile unit, and thus also the most economic lengths of drag chain, cables and hoses.
3. A flat surface is required to support the drag chain. This surface must be kept clear in the chains working area. A support tray is required when there is no satisfactory support for the chain.
4. Fill the carrier cavity no more than 60% to prevent damage. Overfilling the carrier cavity may lead to abrasion, twisting, and binding of cables.
5. Distribute weight symmetrically within the carrier. Position heavy conduits or large hoses toward the outside of the carrier with lighter, more-flexible cables toward the middle.

Data required for selection of cable drag chain:
1. Length of travel which is equal to 2(L - π *R)
2. Number and outside diameter of the cables or hoses to be installed
3. Required minimum bending radius of cables or hoses
4. Weight of cables or hoses
5. Available mounting width on a machine
6. Type of application(dwg. If possible)

Applications
The enclosed electric cable moves along the length of drag chain and this cable chain moves in the moving parts of the machine, improving the life of cable, avoiding the direct stretching in the electric wires, removing traction between wires.
Cable chain have been widely used in numerical control machine tools, electronic equipment and CNC machines.
