Bridge crane wheels
Bridge crane wheels are mainly used in all kinds of lift machines, such as single girder overhead crane, double girder overhead crane, gantry crane, and port crane etc. Bridge crane wheels are various, like single rim wheel, double rim wheel, non-rim wheel, and other nonstandard wheels.
There’re three heat treatment methods according to different requirements: the first is through hardening and tempering, wheel surface hardness HB300-380, mainly used for standard crane products.
The second is surface medium frequency quenching and termpering, wheel surface hardness HB300-380 or HRC50-56, mainly used for products which with low wheel center hardness, high wheel surface surhardness requirements and unsuited whole heat treatment.
The last one is through hardening and tempering, wheel surface hardness up to HRC50-56, wheel surface hardness decay with depth due to the differences of raw materials, forged alloy steel wheels’ the depth of hardening layer up to 15mm and thus low hardness attenuation, mainly used for port crane, bucket-wheel excavator, bucket-wheel stacker reclaimer and other heavy load products.
