Forklift Operator: Stability, load centre and tip-overs

All 14 questions in this test

Every question and its answer choices. The correct answers and explanations appear when you take the test above.

1. What does lateral stability refer to?

   1. Resistance to tipping over sideways
   2. Resistance to tipping forward onto the forks
   3. How quickly the truck can stop on a ramp
   4. How far the mast can tilt back from vertical

2. Ontario guidance lists travelling with the load more than how high as a dangerous activity?

   1. 10 cm above the floor
   2. 1 m above the floor
   3. 50 cm above the floor
   4. 2 m above the floor

3. What happens to a lift truck's stability as the load is raised higher?

   1. Stability does not change at all
   2. Only steering becomes lighter
   3. The truck becomes less stable
   4. The truck becomes more stable

4. Where must your hands, arms, head and legs be while the truck is moving?

   1. Resting on the overhead guard
   2. Outside, to feel for obstacles
   3. Free to signal to pedestrians
   4. Inside the operator compartment

5. Why should you avoid turning the steering wheel sharply at speed?

   1. A sharp turn wears out the horn and the back-up alarm
   2. Turning sharply uses more fuel than driving in a straight line
   3. A sharp turn at speed can tip the truck or spill the load
   4. Sharp turns are only a problem on trucks with cushion tires

6. At about what height should forks or a load be carried when travelling?

   1. Touching the floor so it cannot slide off
   2. About 1 m, so the operator can see under it
   3. As high as the overhead guard allows
   4. About 10–15 cm (4–6 in) above the floor

7. A load is slightly over the truck's rated capacity. What do guidelines say about adding weight to the counterweight?

   1. Never add weight to the counterweight to handle an overload
   2. Have a co-worker stand on the back of the truck while lifting
   3. Add weight only if the load will travel less than 10 metres
   4. Add sandbags until the rear wheels stay firmly on the ground

8. A crate is much heavier at one end. How should you place it on the forks?

   1. Heavier end toward the front wheels, mast tilted back
   2. Heavier end toward the fork tips, mast tilted forward
   3. Heavier end hanging off one side to balance the truck
   4. Lighter end toward the mast so the weight is spread out

9. Why should the load be kept close to the front wheels?

   1. It makes the forks easier to clean
   2. It keeps the lift truck more stable
   3. It lets the operator see over the load
   4. It allows faster travel up any ramp

10. A loaded truck must stop quickly while carrying an unstrapped load. What is the main risk of a sudden stop?

    1. The tires can lose air pressure
    2. The horn can stop working
    3. The load can slide off the forks
    4. The battery can disconnect itself

11. A heavy load is raised high and the operator tilts the mast forward. Which kind of stability is most at risk?

    1. None, because the truck is stopped
    2. Longitudinal, tipping forward
    3. Lateral, tipping to the left
    4. Lateral, tipping to the right

12. Which factors does Ontario guidance say affect lift truck stability?

    1. Speed, acceleration, sharp turns, height, grades and load security
    2. Outside air temperature and the time of day the work is done
    3. The colour of the truck and the brand of its tires and seat
    4. The operator's age and the number of hours left in the shift

13. Besides tipping, what can overloading a lift truck cause?

    1. Lower fuel consumption
    2. A faster top speed
    3. Loss of steering control
    4. Better traction on ramps

14. Your sit-down lift truck starts to tip over. What do safety guidelines tell you to do?

    1. Stay in the truck, held by the seat belt
    2. Jump clear on the downhill side
    3. Stand up and lean against the tip
    4. Jump clear on the uphill side
