Comparison of Chain Drag Technologies
|
Category |
Ordinary drag chain |
Paten drag chain |
|
One.Different structures and materials |
1.The chain plate with arc sliding slotted holes are butt jointed. |
1.The chain plate with arc sliding slotted holes is made from a thickened plate,which greatly enhances the intensity. |
|
2.Without bracing piece,it is liable to be twisted and it is of low intensity. |
2.2 metal bracing pieces are installed between two supporting board to enhance the anti-twisting capacity of the drag chain,and the intensity is greaatly enhanced. | |
|
3.The plating solution does not reach everywhere.which produces dead angle that is liable to be rusted. |
3.There is no dead angle, and no rust, therefore,the service life is longer. | |
|
4.The two jointed chain palte is of low intensitty. |
4.The thickened plate without joint is of high intensity. | |
|
5.The butt joint of the two chain plates is liable to produce errors. |
5.No error. | |
|
6.Due to the restriction of pressing technology,the traditional chain drag uses Q235 materials. |
6.The company adopts laser engraving technology and uses 45# steel,which greatly enhance the intensity. | |
|
Two.Different processing technology |
1.The chain plates with arc sliding slotted holes are stamped with die. |
1.The chain plates with arc sliding slotted holes are engraved with laser. |
|
2.The plate has spilliness,burr and the surface is rough. |
2.There is no spilliness and burr ,and the surface is highly polished. | |
|
3.The surface of the chain palte is not vertical with the processing surface. |
3.The surface of the chian plate is vertical with the processing surface. | |
|
4.For non-standard drag chain,extra expenses on die and extra time is needed. |
4.For non-standard drag chain, it does not need extra expenses on dire and extra time. | |
|
Three.Different treatment of components |
1.The chain plate is galvanized with ordinary technology. |
1.The chian plate is glavanized with anti-corrosive technology. |
|
2.The chain plate does not undergo heat treament. |
2.The chain plate undergoes surface heat treatment to enhance wearaabolity.The intensity of the palte intensity of the plate is greatly enhanced and the service life prolonged. | |
|
3.The pin bearing does not undergo any treament. |
3.The pin bearing undergoes heat treatment,which enhance wearability. | |
|
Four.Different effect |
1.It is seriously worn during the eaely period and che chain hangs down. |
1.It is not liable to hang down.. |
|
2.The chain is liable to be twisted. |
2.The chain is not liable to be twisted. | |
|
3.The bolt on the aluminum alloy supporting board is liable to become loose. |
3.The bolt is not liable to become loose. |
