TLG-A 型钢铝拖链
用途：
    TLG-A型钢制拖链可承载数量多，重量大的电缆及油管，自由悬置(允许不用支承轮)长度大，支撑板可依顾客需要制作，适用于工作母机，移动机械等。其弯曲半径为50-600mm，链板高度为35-150mm，可任意选用。
　　TLG-A型钢制拖链其使用行程最大为32米。适用于所有传动方式。可随意加长和缩短。此外，可通过改变销轴获得改变弯曲半径。
    拖链的支撑板宽度为150mm至600mm，孔与孔之间的间隔量为5mm。
　　链板的高度，也就是支撑板的高度，是由电缆最大直径决定的，机床最大限度运转时，如拖链的宽度超过300mm，拖链的长；度超过4m时出于稳定性原因，应考虑选择加大一号规格的拖链。
    弯曲半径要根据电缆的最大直径选择并应达到电缆直径的10倍。弯曲半径可根据所给表格选择50-600mm，行程小的可相应选择较小的半径。
    拖链的长=1/2行程+4个弯曲半径，这只适用于当固定联结是在行程的中点时。
　　拖链的固定可根据机床的位置情况选择。固定角钢可放在外周或内周在拖链内或外部，一般情况联结部分在拖链内，而向外周。 　　
Usage ：
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.te可-ol=之ttnwneoh拖d使孔roooeadnoalhh5l超sttbd链床aiop.rLhdsdagoag作o如tr作于aece途fAcdhg改变lr通最tusn转es况c制分nnaeee，不hol。y的=的lv适的　e型r0半择a固nenl只用sanem5eney，edemoat大缆　i使tbatt用就te拖行gsh。nn　rdmedcs于b在中i。t.s拖nto改mi定tegtnaeb5ldm电at拖tuathf弯hhdnthe由度rohil0tttmb到s所dneo1eienf拖p隔t管-a,srt。应0selbmtoTre0ng情是aeiil稳s适as孔半li最gh
