As the main support frame of the conveyor cover, the length of Z type steel or the connection angle iron is equal to the length of the installed conveyor cover. Please weld the Z type steel or the connection angle iron on the channel steel or the little stiffening angle iron on both sides of the belt conveyor. If need the stiffening angle iron, at first, weld the stiffening angle iron on both sides of the conveyor, then weld the Z type steel or the connection angle iron on the stiffening angle iron, detailed steps are as following:
1) first weld the little stiffening angle iron ∟40*40*100*4(just for reference, it also can be indicated by users) every 1.5m or 2 m on both sides of the belt conveyor ( eudipleural ). The height from the intermediate frame to the top of little stiffening angle iron should ≥50mm ( it also can be decided by users).
2) Then weld the Z type steel 30*50*30*(2.0~3.0),( just for reference, it also can be replace by angle iron) and fix it on both sides of the intermediate frame top, the inner size should be 10-20mm bigger than outside size of intermediate frame.
3) After being welded please remove welding slag then paint.
