TEZ plastic weight bearing drag chain

Cable drag chain—also referred to as cable chain, cable carriers cable track, and energy chain—are flexible hollow structures used to guide, support, and protect cables, hoses, and hydraulic lines when makes reciprocating motion.

Why use drag chains?

Drag chains are used to guide, support and protect the items of cables, hoses and hydraulic lines when in motion. Without drag chains, the potential for such structures to become tangled or damaged would be high

Installation for cable drag chain

Put a screw driver vertically into the opening hole at both ends of the cover and then open the cover .put the drag chain for cables and oil pipes according to the instructions provided .put the cover back .note that the fixed end and the moving end of a cable should be fixed solidly,when used in a long sliding service ,it is recommended to use some supporting rollers or guide groove , it will be perfect.

Principle for selecting cable chain
inner height :take the most thick piece of the internally installed cable ,oil pipe,gas pipe or water pipe as the reference height plus 10%of the space height at least as the inner height HI.if overlapping ,take the overlapped height as the actual height .
inner width :take the sum of the outside diameter of the thicker cables ,oil pipe,gas pipe or water pipe as the reference of the inner width and leave at least 10% of the space as a margin
radius of a bend :take the biggest radius of a bend of a cable ,oil pipe,gas pipe or water pipe as a reference value and leave 10%of the space as a margin

Basic parameters of cable chain
Material:reinforced nylon.
It can stand with high pressure and has good tensile strength,toughness and elasticity,wearing and flame resistance
Resistances:It is oil and salt resistant.
operating speed and acceleration :Max.operating speed is 5m/sec.and max.acceeleration is 5m/sec.(specfic speed and acceleration depends on specific situation).
Service life: Under normal conditions,5million reciprocating motions can be reached (which is also related to the operating conditions.)

Construction of the drag chains
The appearance of the chain looks like the crawler of a tank consisting of certain number of joints.The joints of crawler are freely turned round.
The same series of chain has same inner height and out height and same pitch but the inner height and bend radius R can be made per different specifications.
A unit chain joint is consisting of a left-right chain plate and a updown cover.Each chain joint can be opened up so as to facilitate assembly and dismantal without threading.Cables,oil pipes and gas pipes can be put into the drag chain after the cover plate is opened.
Spacer are available for use,which are able to divide the space inside the chain into divisions according to requirements.
