Question 1

Which type of forklift is most suitable for use in a cold storage freezer environment?

Accepted Answer

Electric forklift with cold-storage rated batteries

Answer

Electric forklifts with cold-storage rated batteries are designed to withstand low temperatures and avoid exhaust emissions in enclosed freezer spaces.

Question 2

What is a 'slip sheet' and how does it differ from a standard wooden pallet?

Accepted Answer

A slip sheet is a thin sheet of plastic or fiberboard that replaces a pallet and requires a push/pull attachment

Answer

Slip sheets are flat, thin platforms that replace pallets and require a specialized push/pull forklift attachment to handle, saving storage and shipping space.

Question 3

What is the maximum allowable fork wear before a fork must be removed from service?

Accepted Answer

10% reduction in original thickness

Answer

ASME/ANSI standards specify that forks with a 10% or more reduction in original thickness at the critical cross-section must be removed from service.

Question 4

When stacking loads in a warehouse, how should heavier loads be positioned relative to lighter loads?

Accepted Answer

Heavy loads on the bottom, lighter loads on top

Answer

Placing heavier loads at the bottom lowers the center of gravity of the stack, making it more stable and preventing toppling.

Question 5

What is the function of a 'load backrest extension' on a forklift?

Accepted Answer

It prevents loads from falling backward onto the operator when elevated

Answer

The load backrest extension (LBR) creates a vertical barrier behind the forks to stop loads from sliding back and striking the operator or mast.
