TLILIC0003 Forklift Stability and the Stability Triangle

Question 1

What is the 'stability triangle' on a standard counterbalanced forklift?

Accepted Answer

The three-point suspension formed by the two front wheels and the rear axle pivot point

Answer

The triangular shape formed by the mast, forks, and counterweight

Answer

The area between the load, the operator, and the rear axle

Answer

The three contact points between the forks and the load

Question 2

On a counterbalanced forklift, where is the fulcrum point located?

Accepted Answer

At the front axle between the two drive wheels

Answer

At the centre of the rear axle

Answer

At the tips of the forks

Answer

At the base of the mast

Question 3

What happens if the combined centre of gravity moves outside the stability triangle?

Accepted Answer

The forklift will tip over in the direction the centre of gravity has moved

Answer

The forklift's speed automatically reduces

Answer

The load capacity indicator will sound an alarm

Answer

The rear wheels will lift, but the forklift remains balanced

Question 4

What is the 'combined centre of gravity' on a forklift?

Accepted Answer

The single point representing the combined weight distribution of both the forklift and its load

Answer

The centre of gravity of the load alone

Answer

The centre of gravity of the empty forklift alone

Answer

The midpoint between the front and rear axles

Question 5

Which type of stability refers to the risk of a forklift tipping sideways?

Accepted Answer

Lateral stability

Answer

Longitudinal stability

Answer

Rotational stability

Answer

Dynamic stability

Question 6

Which factor directly reduces a forklift's longitudinal (forward/backward) stability?

Accepted Answer

Raising the load to a greater height while stationary

Answer

Using pneumatic tyres instead of solid tyres

Answer

Carrying a heavy load with the mast tilted fully back

Answer

Operating at low speed on a flat surface

Question 7

What is the primary purpose of the counterweight on a counterbalanced forklift?

Accepted Answer

To offset the weight of the load being carried and keep the combined centre of gravity within the stability triangle

Answer

To increase the speed of the forklift when travelling without a load

Answer

To provide additional braking force when descending ramps

Answer

To protect the engine from damage during collisions
