Question 1

When traveling UP a ramp with a LOAD, you should:

Accepted Answer

When loaded, the center of gravity shifts forward. Driving forward uphill keeps the load stable against the backrest and maintains traction on the front drive wheels.

Question 2

When traveling DOWN a ramp with a LOAD, you should:

Accepted Answer

To prevent the load from sliding off the forks and the truck from tipping forward, you must travel in reverse so the load remains pointing uphill.

Question 3

When traveling UP a ramp EMPTY (no load), you should:

Accepted Answer

When empty, the counterweight is the heaviest part. It should be kept uphill to prevent the forklift from tipping backward. Thus, you drive in reverse going up.

Question 4

When traveling DOWN a ramp EMPTY (no load), you should:

Accepted Answer

Driving forward downhill keeps the heavy counterweight uphill, maintaining stability and traction.

Question 5

Turning on a ramp is:

Accepted Answer

Turning on a grade shifts the center of gravity laterally across the slope, creating an extremely high risk of a lateral tip-over. It is strictly prohibited.

Question 6

OSHA defines a 'grade' requiring special travel procedures as a slope greater than:

Accepted Answer

OSHA 1910.178(n)(7)(i) specifically mandates the load-upgrade rule for grades in excess of 10 percent.

Question 7

When traveling on a ramp, the forks should be:

Accepted Answer

Forks may need to be raised slightly higher than on flat ground to avoid 'bottoming out' the tips on the incline, but they should be kept as low as possible.

Question 8

If a load blocks your view while going UP a ramp, you should:

Accepted Answer

You cannot drive in reverse going up a ramp with a load (load would be downhill). You must drive forward, so a spotter is required if visibility is blocked.

Question 9

The phrase 'Keep the Load Uphill' applies:

Accepted Answer

This simple rule ensures stability: If loaded, the load points up the slope regardless of travel direction.

Question 10

Why must you avoid parking on a ramp?

Accepted Answer

Parking on an incline relies entirely on the mechanical brake, which can fail. If unavoidable, wheels must be chocked.

Question 11

When traversing a ramp, the forklift's center of gravity shifts:

Accepted Answer

Gravity pulls the center of mass toward the downhill side relative to the wheelbase, reducing the stability margin.

Question 12

If the forklift stalls while climbing a ramp:

Accepted Answer

Maintain control. Rolling backward uncontrolled or turning can lead to a tip-over.

Question 13

Bottoming out (where the chassis scrapes the ground) usually occurs at the:

Accepted Answer

The 'breakover angle' at the top of the ramp is where the center of the forklift chassis is most likely to get high-centered.

Question 14

To improve traction on a wet ramp:

Accepted Answer

Mechanical traction aids (cleaning/sand) are the only safe solution. Diagonal driving is prohibited.

Question 15

Coasting downhill in neutral:

Accepted Answer

You must keep the forklift in gear (or drive mode) to maintain engine braking and steering control.

Question 16

If a ramp has a 10% grade, it rises:

Accepted Answer

A 10% grade means a vertical rise of 10 units for every 100 horizontal units (Rise/Run).

Question 17

Before driving onto a portable yard ramp (used for loading trucks from ground level):

Accepted Answer

Portable ramps introduce multiple hazards: movement, collapse, and traction.

Question 18

On a ramp, the load backrest is vital because:

Accepted Answer

When tilting back for ramp travel, gravity pulls the load toward the mast. The backrest prevents it from hitting the operator.

Question 19

If you drive forward DOWN a ramp with a load:

Accepted Answer

All three are major risks. The load slides off, the CG moves forward (tipping), and weight transfers off the drive wheels (braking loss).

Question 20

When positioning a load on a ramp (e.g., placing it on a truck bed on an incline):

Accepted Answer

The tilted mast and sloped ground change the stability geometry. Lifting high on a slope is extremely dangerous.

Question 21

What is the primary reason for driving backward up a ramp when EMPTY?

Accepted Answer

An empty truck is rear-heavy. Driving reverse up keeps the heavy end uphill, preventing a backward tip-over.

Question 22

If the ramp is very steep, what might happen to the fork tips?

Accepted Answer

The transition from flat to steep can cause the fork tips to hit the concrete. You may need to lift them slightly higher than 4 inches to clear the transition.

Question 23

Which forklift type typically has the best gradeability (climbing power)?

Accepted Answer

IC trucks generally have more torque and better traction for steep grades compared to electric warehouse equipment.

Question 24

When approaching the top of a ramp, you should:

Accepted Answer

Breaking over the top changes traction and visibility. Slow down to maintain control.

Question 25

Soft shoulders or edges on outdoor ramps can cause:

Accepted Answer

Stay in the center of outdoor ramps. Soft edges can collapse under the immense weight of a forklift.
