PCC


Product Features


CSB-PCC® cable chains are made of high strength and anti-wear plastics, The cable chains are used in a variety of motion modes and strokes. CSB-PCC® cable chains can carry the total cables, data cables, fiber optic cables and energy hoses, such as power cables, encoder cables, switch signal cables, oil and gas hoses.

CSB-PCC®拖链应用图标



▊ Calculation of the chain length

The fi xed end in the center of the travel is the most costeffective solution.

The chain length LK is calculated by using half the length of travel and adding the value K if the fi xed end of the chain is located in the center of the

travel, You can get the value K from the size table in every series chain. It is the most cost-effective solution if Placing the fi xed end in the center of

the travel, Because it requires the shortest chain, cables and hoses.

CSB-PCC®拖链长度计算



▊ Camber

The largest possible unsupported length is influenced by the design, material and camber. Camber is the curve of the upper run along its unsupported length. All CSB-PCC® chains are manufactured with camber. In the Installation dimensions section of each respective chain description, you will fi nd the measurement HF, which specifi es the necessary clearance height, taking the camber into account. The camber allows for longer unsupported lengths and increases service life and operating safety. Upon request, we can deliver chains without camber for restricted space applications - however, these no camber chains do not have the same load-bearing capacity.

▊ Unsupported applications

If the upper run of the chain operates without touching the lower run over the entire travel, it is called an unsupported application. The distance between moving end and the beginning of the radius curve of the is called the unsupported length. The unsupported application is the most common. CSB-PCC® chains are very well suited for high dynamics and long service life. The maximum unsupported length depends on the fi ll weight and the type of chain or tube. As a result, we differentiate among three types of unsupported length.



▊ Unsupported with Straight Upper Run FLG

The chain is unsupported FLG when the upper run still has camber, is straight or has a maximum sag of 1/2 of the chain link height. Installing the chain in FLG is always recommended. The runs smoothly without additional vibration.

 The FLG type of installation always generates the longest service life and can be operated with the max. values for speed and acceleration.



▊ Unsupported with Permitted Sag FLB

The chain is unsupported FLB when the sag is more than 1/2 Chain link height and less than the smallest available radius of this CSB-PCC® series. In most applications the can be used unsupported FLB without any problems. There are restrictions concerning the maximum speed and acceleration.

The FLG type of installation always generates the longest service life and can be operated with the max. values for speed and acceleration.



▊ Critical Sag

When the sag of the chain is higher than allowed for FLB, it is in critical sag. Using an chain in critical sag should be avoided or solved with special solutions. An chain should never be installed with critical sag. Applications may reach critical sag after long service times. The chain or tube should be replaced in these cases.

▊ Vertical, Hanging Applications

For hanging applications, heights of over 100m are possible with CSB-PCC®. Particularly in the area of material fl ow technology, the chain enables a bundled supply of a wide variety of cable types. The use of an chain ensures that individual cables are not entangled in parts of shelves or protruding pallets. We recommend locking mounting brackets for vertical hanging applications.



▊ Cables and hoses

Two important factors in vertical hanging applications are how the cables and hoses lay in the chains and and how they are secured at the end points: all cables and hoses must be hung so that they bear their own weight. The chain the chain fulfi ls the function of orderly conduit bundling only and should not absorb any further tensile forces. The chain interior separation elements should be used for distinct division of all cables and hoses. The cables and hoses must be secured carefully to both end points of the chain. The strain relief must be designed so that the opposite run cannot catch. Safe strain relief and clear separation of the cables and hoses are the basic prerequisites for hanging installations. Cables must be able to move freely and bear their own weight.



▊ Vertical Motion with Lateral acceleration

If the application has a purely vertical movement without lateral acceleration, a lateral support is not necessary. If lateral acceleration occurs, lateral guidance of the chain must be provided in most cases. The diagram shows the principle of such guidance. Partial guidance is also an option however, it must at least cover the area in which the chain may sway. Lateral acceleration can occur in two directions. The lateral guidance must be installed accordingly. If you have a choice, the layout in fi gure A is preferred. The lateral acceleration then acts transversely to the chain, where it is more stable. When using a guide, an chain with camber should be selected. This ensures that the chain is pressed into the trough.

▊ Vertical Standing Applications

Standing applications are standard on many machines and plants. Cables will be guided safely in vertical strokes.



▊ Mounting Brackets

The mounting brackets must be attached so that the chain cannot bow outwards. Locking mounting brackets are highly recommended because they can be attached fl ush to the machine.



▊ Cables and Hoses

Cables and hoses must be laid in the chain so that they can bend freely and bear their own weight. For precise guidance of the cables and hoses, we strongly recommend interior separation elements. Cables must be strain relieved at both ends.



▊ Lateral Acceleration

If lateral acceleration occurs, the chain should, in most cases, be supported along the outer radius. For higher chain heights, it is generally recommended that at least the first three links on the outer radius be supported. For maximum heights and weights, the whole distance must often be supported. Due to the wide variety of combinations involving fi ll weights, stroke heights, chain types and bend radius, we recommend you contact with us.

▊ Side-mounted Chains

CSB-PCC® chains placed on their side can be used unsupported to a limited extent. The turned unsupported length in this case is dependent on the following factors:

 1, Fill weight

 2, Width of the chain

 3, Bend radius

 4, Parallel placement

 We recommend locking mounting brackets for sidemounted applications

侧向安装拖链

The greater the fi ll weight of the chain, the shorter the available unsupported length. When placed on its side, the chain width, in effect, becomes the height. As this height increases, the chain becomes proportionally more stable. If further movement in a second axis is added to the parallel motion of two chains, the unsupported length is impaired. For applications with low fi ll weight, the standard mounting chain is supported brackets are adequate. If, however, the fi ll weight is high and the travels are long, the chain must then be supported either in whole or in part. Due to the variety of application possibilities, we strongly recommend you make use of our consulting services. Side-mounted chains are strongly recommended if the installation height is restricted. Standard values for unsupported lengths, side-mounted, upon request. The unsupported lengths can be extended by supporting the links next to the mounting brackets.



▊ Distribution Rules | Cables and Hoses

In order to ensure that the chain is functioning properly and to avoid damage to the cables or hoses, the following principles must be observed when laying cables or hoses:


电缆或者软管在拖链中的布置▊ This minimum clearance would be 10% for electrical round cables, 20% for hydraulic hoses.
电缆或者软管在拖链中的布置▊ In order to reduce the possible friction, avoid pipes with different skin materials such as cables or hoses.(eg: cable and hydraulic hoses)
电缆或者软管在拖链中的布置▊ In applications where multiple cables and hoses are used, in order to avoid mutual friction between them, it is preferable to place them in a suitable separate space and separate them from each other with a spacer. If there are no conditions to achieve, make sure there is enough space between them to avoid mutual friction (H<D).
电缆或者软管在拖链中的布置▊ The cables or hoses are laid in a symmetrical manner according to their diameter and weight. The largest and heaviest cables are placed on the outside of the section and the small and light cables are placed on the inside.
