What you'll practise
Try a question
Why does the eTool say a large rectangular box should be loaded widthwise across the forks rather than lengthwise?
- Loading it lengthwise blocks the horn
- Widthwise loading makes the forks longer
- Loading it widthwise blocks the operator's view, so lengthwise is the safer way
- Loading it lengthwise moves the load center forward and can exceed capacity
Show the answer
D. Loading it lengthwise moves the load center forward and can exceed capacity — Placing a long load lengthwise shifts the load center forward, away from the front wheels, which can exceed capacity and lift the rear wheels.
