The TLG-A 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 user`s requirements. It is suitable for machine tools and moving machines. Their bent radius ranges from 50-600mm and the chain`s height is from 35 to 150mm. Users can make a free selection of them. The TLG-A type drag chains has a max. travel range of 32 meters and are suitable for all kinds of transmissions. It can freely be made longer or shorter. In addition, the bend radius can be changed by changing the pinshaft.
The 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 cables. When the machine tool is working in the highest speed and if the max. width of the drag chain is longer than 300mm with the chain`s length longer than 4m, one size larger than normal should be selected just out of considration of safety.
The bend radius should be selected according to the max. diameter of a cable and shoulod be 10 times of the diameter 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 = 1/2 travel 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 location of 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 or in the oute side. In common cases, it is in the inner side of the chains and face towards outside.
Note: 1. When you need drag chain schedule gets 20 meters, width is 500 millimeter above, e. when speed gets. Need to install the return roller. 2. TLG steel drag chain of support plate width (L) can be any design. 3. "a" on the chart for each of the drag chain biggest hole size, outside of the "c" for this kind of drag chain high dimension, outside of the drag chain should support plate width + 2 d wide, "e" for the thickness of the plastic article insulation, "f" refers to the installation of joint distance between two holes. "g" for the mounting holes to drag chain of the lateral distance. "h" refers to the size of the mounting holes, "k" refers to the width of the joint board.
