It certainly doesn’t look as menacing as many of its larger forklift cousins. 
But your electric pallet jack has its own set of safety concerns. These trucks come in a number of varieties and those are broken out by the Industrial Truck Association this way:
Class 3 – Electric Motor Hand Trucks
- Lift Code 1 Low Lift Platform
- Lift Code 2 Low Lift Walkie Pallet
- Lift Code 3 Tractors (Draw Bar Pull Under 999 lbs.)
- Lift Code 4 Low Lift Walkie/Center Control
- Lift Code 5 Reach Type Outrigger
- Lift Code 6 High Lift Straddle
- Lift Code 7 High Lift Counterbalanced
- Lift Code 8 Low Lift Walkie/Rider Pallet
What are the safety concerns then?
Could you name them all? Here is a list as compiled by Toyota Material Handling
