Axle and wheel loadings
Axle and Wheel Loadings
Axle loadings can be calculated as shown. To obtain wheel loadings, divide the axle loadings by the number of wheels carried on that axle. (For the purpose of these calculations two load wheels in line, as on a reach truck, are as though carried on a single axle). Truck dimensions, service weight and unladen loadings on each axle must relate to truck specification.
- Loading on rear, steer axle: QR=unladen, QRL=laden
- Loading on front, load axle: QF=unladen, QFL=laden
- Q = load weight
- Y = wheelbase
- A = C + X (counterbalance truck)
- A = C + reach travel - X (reach truck)
Counterbalance truck and reach truck with
'reach out'
- QRL = QR - Q x A / Y
- QFL = Truck Weight + Q - QRL
Reach truck with 'reach in' and pallet truck, etc.
- QFL = QF + Q x B / Y
- QRL = Truck Weight + Q - QFL
