What is the material for Crane Wheel Blocks?
ZG340-640 cast steel or ZG-50SiMn low alloy steel is used to make the wheels. The working surface must be quenched, and the depth must be at least 20mm. The rolling surface hardness of ZG340-640 cast steel wheels is 300-350HBW, while ZG-50SiMn wheels have a rolling surface hardness of 420-480HBW.
To compensate for the gauge error caused by track and wheel installation, the width of the wheel tread must be slightly larger than the width of the rail top. Increasing the height of the wheel flange can increase the contact area between the wheel flange and the rail side, lowering contact stress and extending wheel life. The wheel flange must frequently bear the lateral force of the crane when it is running at a slant and be sufficiently thick. The wheel flange frequently has a 1:5 slope, and an arc transition is used between the wheel flange and the tread.
