TLG drag chain    Character:
  The TLG drag chains are suitable for installing a large quantity and heavy duty of cables and oil pipes which allow suspending installation (supporting is not allowed)and is lengthy.The supporting plate can be made according to the users requirements.It is suitable for machine tools and moving machines.Their bebt radius ranges from 50-600mm and the chains height is from 35 to 150mm.users can
make a free selection of them.
  The TLG type drag chains have a max travel range of 32 meters and suitable for all kind of transmissions.It can freely be made longer or shaort.In addition,the bend radius can be changed by changing the pin shaft.
  The TLG width of the supporting board is from 150mm to 600mm.the distance between the holes is 5mm.
  The height of the supporting board depends on the max.outside diameter of the cable.When the machine tool is working in the highest speed and if the max the width of the drag chain is longer than 4m,onesize larger than normal should be selected just out of considerationof safety.
  The bend radius should be selected according to the max.diameter of a cable and should be 10 times of the cable used.The bend radius can be selected as 50-600mm according to the given table.Small radius should be selected for those ones with small travel range.
  Drag chain length=1/2travel range+4 bend radius,this is only used for the fixed connection which is located at the middle point of the travel range.
  The fexation of the drag chains can be done according to the machine tools.The angle steel can be put in the outer or the inner,in other words,in the inner side of the chains of in the oute side.In common cases,it is in the inner side of the chains and face towards outside.
