Every question and its answer choices. The correct answers and explanations appear when you take the test above.
A lift truck's capacity plate is missing. What should the operator do?
- Ask another operator what it can lift
- Not operate the truck and report it
- Operate it, but only with light loads
- Estimate the capacity from a similar truck
You must move carpet rolls or drums that do not sit on pallets. What does guidance recommend?
- Carry the load balanced across the very tips of the forks
- Tie the load to the mast with a strap or rope
- Use the proper attachment for that kind of load
- Ask a co-worker to ride along and steady it
A walk-behind electric pallet truck controlled by a pedestrian belongs to which truck class?
- Class 7, rough terrain lift trucks for outdoor sites
- Class 5, internal combustion pneumatic tire trucks
- Class 1, electric motor rider counterbalanced trucks
- Class 3, electric motor hand trucks
Except during a test, when may material handling equipment be loaded beyond its maximum rated load?
- For short distances under 10 metres
- When extra counterweight has been added
- When an experienced operator is driving
- Never
A lift truck is modified in a way that affects its capacity. What is required?
- A note in the operator's daily log and a slower speed limit for the first month
- Written approval from the maker or an engineer, and updated capacity plates
- Approval from the shift supervisor and a sticker that says modified
- Nothing, as long as the truck passes the next daily circle check
What does Ontario's regulation require about marking a lift truck's maximum load?
- It must be written only in the owner's manual kept in the main office files
- It must be plainly marked so the operator can tell the maximum load in any condition
- It must be painted on the floor of the loading dock beside each door
- It only needs to be marked on trucks bought after the year 2000
Which class covers rough terrain lift trucks used on uneven outdoor ground?
- Class 3
- Class 7
- Class 1
- Class 2
Which information does a lift truck's capacity plate show?
- The date of the operator's last training course and the trainer
- The fuel price and the cost of a new battery
- Rated capacity at a stated load centre and lift height
- The name of the supervisor on the current shift
An order picker or reach truck used in narrow warehouse aisles is in which class?
- Class 2
- Class 8
- Class 6
- Class 4
Why should a gas or propane lift truck not be used where exhaust can build up?
- Exhaust can cause carbon monoxide poisoning
- Exhaust drains the battery faster than normal
- Exhaust makes the floor slippery for tires
- Exhaust weakens the forks over a few weeks
What separates a Class 4 truck from a Class 5 truck?
- Class 4 runs on electricity; Class 5 runs on propane fuel
- Class 4 has cushion tires; Class 5 has pneumatic tires
- Class 4 is for outdoor use; Class 5 is for indoor use only
- Class 4 lifts people; Class 5 is limited to lifting loads
Electric and engine-powered tow tractors with a drawbar pull over 999 lb are grouped in which truck class?
- Class 6
- Class 3
- Class 2
- Class 7
When must a lift truck have an overhead guard, cab or screen for the operator?
- Only when the operator is younger than 18 years old
- Only when the truck is used outdoors in rain or snow
- When the operator may be exposed to falling material
- Only on trucks that travel faster than 15 km/h on site
Truck classes and the capacity plate: key rules to remember
Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗
Appendix II (Industrial Truck Association classes)
- Class 1: electric motor rider trucks (counterbalanced, sit-down or stand-up).
- Class 2: electric motor narrow-aisle trucks (order pickers, reach trucks, turret trucks, side loaders).
- Class 3: electric motor hand trucks (walkie pallet trucks and other pedestrian-controlled units).
- Class 4: internal combustion engine trucks with cushion (solid) tires.
- Class 5: internal combustion engine trucks with pneumatic tires.
- Class 6: electric and internal combustion tow tractors.
- Class 7: rough terrain lift trucks.
- Class 8 in the ITA list covers personnel and burden carriers; Manitoba's code covers Classes 1 to 7.
- A competent operator is assessed on, and should operate, only the class or classes of truck they were trained and assessed on.
Capacity (data) plate and load chart
- The capacity plate shows the model and serial number, the rated capacity at a given load centre and lift height, the maximum fork or attachment height, the truck weight and, on electric trucks, the minimum battery weight.
- Reg. 851 s. 51(1)(c): a lifting device must be plainly marked so the operator can tell the maximum rated load under any operating condition.
- Reg. 851 s. 59: material handling equipment must not be loaded beyond its maximum rated load, except during a test.
- Every truck should display the maximum rated load and how the safe load changes with reach; if the truck is modified, the information must be revised to the new rating.
- Modifications or additions that affect capacity or safe operation need the written approval of the manufacturer or a qualified professional engineer, and the plates and decals must be changed (Manitoba Code of Practice s. 4.2).
- An operator should not use a lift truck that has no capacity rating information (CCOHS).
- Attachments (for example a carpet spike or drum grab) change what the truck can safely carry; use the proper attachment for special loads.
- The capacity of the forks themselves also matters; overloading can bend and weaken forks.
Selecting the right truck
- Truck choice should match the load, the terrain, the atmosphere and the building design.
- Gas, propane or diesel trucks should not be used where explosive dust, gas or vapour may be present, or where exhaust can build up and cause carbon monoxide poisoning.
- Trucks should have an overhead guard or screen where material could fall, warning devices and lights suited to the workplace, and a seat belt or operator restraint where feasible.
