Selecting of Drag chains
1.The hole diameter of the inner cavity of supporting board D1
=d+¡Ö0.1d (take round number).Where,d=outside diameter
of cables,wires,liquid/gas hoses.
2.The height of the supporting board and the model number
TLXX of drag chains depends on the max, hole diameter of the
inner cavity of the supporting.
3.The bend radius depends on the functions of the drag
chains.
(1).When there is a large load from larger calibre or cables on
the drag chains,high strength model I supproting board
(integral)should be used.
(2).When the size of the connectors are greater than that of
the hole diamete of the inner cavity of supporting board of
frequent assembly or dismantal operations are required,type
lll supproting board (frame type) can be used.
4.The width of supporting board B1 can be decided accroding
to the quantity of the cables installed so that the width of the
drag chain B can be arrived.
5. When limited by locations or environment and if bracing
boardwith steel strapsare needed,please contact our company
for soIutlons. |
| When back up wheel is not allowed,relatonship between the drag chain length and the additiona lad |
 |
| Note:If the drag chain length exceeds a limit where a back up wheel is not allowed to use,it is recommended to add a supproting wheel beneath the drag chain,avoid hanging down but improve the stability. |

Drag chains with 3 chain board
One or more drag chain boards can be Installed on a wider
drag chain,because the max.length of the supporting board is
600mm-650mm. This arrangement can also improvethe stability
of the narrower chains. In this way, the conduit and the cables
can be separateddfromoneanother by a third chain board.
Note£ºParameters D,12,e be used for SLE type and f,J,k for
TLtype
Elastic status for hydraulic pipes
Note that the pressure of a hydraulic pipe may extend or
contract downward,so the elasticity should be taken into
consideration,especially under high pressure or with long length.
