How to choice the weld ball mount(2)?
Time：2016-10-31 Author:However,Do you know consider from which aspects ?
1)First of all ,make a applicable choices for china weld ball mount.Including the type of ball,the drag force of the ball,trailer arm height,towing arm drag force，The plate thickness of the trailer arm and ball linking,the thickness of the square tube trailer arm.Especially,The drag force of the trailer hitch ball arm is always greater than the maximum drag force.For example,If the loading capitity up to the 1000KG ,We ’d better choice up to 1500 or more.
2)choice the better sense sight of the view ,Which separately reflect on the link board for the trailer arm is comparatively thick just for fine.Besides,The position of the wall thickness of tube trailer arm as thick as possible.It’s better for making combine the trailer arm linking plate with the location of the welded tube if it’s more smooth for welding.
3)choice the thickness of the china weld ball mount.Many people are puzzled by the difference in the size of the trailer arm.The difference of computing units chinese and American led to the difference emerge.
However,Does the size of the square for the trailer arm is no require well?
The external diameter of the material used in china is 50MM,While,Which used for forgigner is 2 inchs equal to 50.8MM.
In fact,The mainstream of domestic arm length is the diameter of 50MM as a standard ,For another reference is the British standard.
According to many experience from many professional ideas ,We give some conclusions :
The domestic party mouth bar diameter is less than or equal to 52MM plus welding reinforcement diameter generally less than 51MM.
The china trailer hitch ball arm using imperial standard is more difficult.
The British standard square mouth bar diameter is greater than or equal to 53MM plus generally more than 52MM diameter welding reinforcement.
Practical English standard or China trailer ball arm can be compatible. So when the trailer ball arm size is critical for the best choice of square is less than or equal to 50MM.
