Wheel Block & Open Teeth Wheel Set
Choice of Rail Wheels
Rail >>> Wheel >>> End carriage >>> Power >>> Gear unit
According to FEM 4.2.4.1.2 ; FEM 4.2.4.1.3
Wheel pressure P'max =D x ( b-2 x r ) x K
Wheel diameter=D (cm)
Useful of the rail head width=b (cm)
Useful of the rail head rounded corne=r (cm)
Materiality the limiting pressure=K (kg/cm^2 )
Load pressure P'=(kg)--At four wheel crane system

According to CMAA 4.13.3
Wheel pressure P'max = D x W x K
Wheel diameter=D (inches)
Effective rail head width=W (inches)
Hardness coefficient of the wheel=K (Lb/in^2 )
Where : K=BHN x 5 (for wheels With BHN ≤260)
K=1300 (BHN / 260) ^ 0.33 (for wheels With BHN ≥ 260)
