girder pole
2.Taking the prohect example as basis,the author describes thoretically the design of the tank which is very rarely used in foretime inland and has a conical roof supported by big sized beam and pole,the foreign and domestic related design standards are introduced,calculating formula for the tupical structures inclined rafter,cross girder and vertical pole are given,and the calculating mote is compiled with excel electronic form,
3.We mainly produce shifting fork and release fork of large-scale and heavy-duty truck; shifting fork, release fork, shifting block, choosing-gear shaft, reverse-gear shifting fork shaft, right-and-lfet steering joint arm, upper cross arm shaft, wheel hub, link rod of all kinds of cars right-and-left supports, nipbutton of train auto-girder parts; Centeral wedge, fixed lean-board of absorber; shifting fork, erankshaft, link rod, under-link board, startup pole of motocycle; mould forging of mine, construction machinery, textile machinery, non-ferrous metal industry, etc.
