Answer:
Vertical Wheel Loads
QC (a component due to the self-weight of the crane)
QH (a component due to the hoist load)
Horizontal Wheel Loads
HT (a component due to starting/braking the crane bridge)
HS (a component of skew forces due to starting/braking the crane)
HT3 (a component due to starting/braking the crane trolley or hoist)
Longitudinal Loads
HL (a component due to starting/braking the crane)
If a skew force (S) or a buffer force (HB) is also effective, it can be specified below the table.
