Stability Triangle - Figure 1
Notes:1. When the vehicle is loaded, the combined center of gravity (CG) shifts toward line B-C.
Theoretically the maximum load will result in the CG at the line B-C. In actual practice, the combined CG should never be at line B-C.
2. The addition of additional counterweight will cause the truck CG to shift toward point A and result in a truck that is less stable laterally.

Effective Powered Industrial Truck Operator Training Program
• Four major areas of concern must be addressed:– The general hazards that apply to the
operation of all or most powered industrial trucks;
– The hazards associated with the operation of particular types of trucks;
– The hazards of workplaces generally; and,– The hazards of the particular workplace
where the vehicle operates.
20
Types of Powered Industrial Trucks
• There are many different types of powered industrial trucks covered by the OSHA standard.
• Commonly used types include:– High lift trucks, counterbalanced trucks, cantilever trucks,
rider trucks, forklift trucks, high lift trucks, high lift platform trucks, low lift trucks, motorized hand trucks, pallet trucks, straddle trucks, reach rider trucks, high lift order picker trucks, motorized hand/rider trucks, and counterbalanced front/side loader lift trucks.
• A single type of truck can only be described by calling it by all of its characteristics, (e.g., a high lift, counterbalanced, sit down rider truck).
21
Unique Characteristics of Powered Industrial Trucks
• Each type of powered industrial truck has its own unique characteristics and some inherent hazards.
• To be effective, training must address the unique characteristics of the type of vehicle the employee is being trained to operate.
22
A PIT is a PIT NOT a CAR
Controls are different from those of cars. Steer very differently than cars. Are used for different purposes than cars. Steer from the rear, and have drive wheels in the
front. When turning, the rear end swings in a circle. Front drive wheels support most of the load. Less steering control when turning, especially if
loaded. Difficult to stop quickly and dangerous to swerve.
23
Components of a Forklift Truck*
*One of the most common types of powered industrial trucks
24
Classes of Commonly-Used Powered Industrial Trucks*
• The Industrial Truck Association has placed powered industrial trucks into 7 classes.– Class I - Electric motor rider trucks– Class II - Electric motor narrow aisle trucks– Class III - Electric motor hand trucks or hand/rider trucks– Class IV - Internal combustion engine trucks (solid/cushion
tires)– Class V - Internal combustion engine trucks (pneumatic
tires)– Class VI - Electric and internal combustion engine tractors– Class VII - Rough terrain forklift trucks
* Note that this classification refers to commonly-used vehicles and does not include all powered industrial trucks covered by the OSHA standard.
25
Class I - Electric Motor Rider Trucks
• Counterbalanced rider type, stand up
• Three wheel electric trucks, sit-down
• Counterbalanced rider type, cushion tires, sit-down (high and low platform)
• Counterbalanced rider, pneumatic tire, sit-down (high and low platform)
26
Class I - Electric Motor Rider Trucks

Must be done at least daily or at the beginning of each shift
Check the power-plant
Gas, Diesel or Propane Powered
Electric Powered
Check for damage and proper operation.
Pre-use Inspection
32
Performance DataGross vehicle weight without a load will
always exceed the vehicle’s rated lifting capacity
Gross vehicle weight will normally be about 2 times the vehicle’s rated capacity
Weight distribution varies depending on load weight and position
33
NEVER EXCEED the rated load capacity of your PIT
Look for Impact or Capacity plate to find: >machine working capacity>gross vehicle weight>rated load center >capacity rating with attachment>tire data>attachment identification>maximum lift height
Load Stability
34
Reduce your load if:The load is too tall, wide, oddly shaped or if
you are using attachments.A high lift is involved or if the route is rough.The load can’t be centered on the pallet or
carried close to your drive wheels.You have to make tight turns or travel on a
ramp or slope.
35
To Keep the Load Stable:Space your forks as far apart as possible.Make sure the load won’t shift while
traveling.Secure loose or slippery items.Transfer loads on broken pallets to sound
pallets before picking them up. Wrap or strap loads made up of individual
items.
36

37
Stability in PracticeYour PIT and load become less stable in
any of the following situations:– whenever the load is raised
– when you are turning
– on slopes, either front to back or side to side
– when tilting the load forward or backward, or side to side
– on rough or uneven surfaces

40
Counterbalance
load is carried at front of vehicle and is offset or counterbalanced by the weight of the vehicle located behind the drive tires which act as a pivot point internal combustion-engine, steer axle,
transmission, counterweight, and frame electric powered battery, control panel,
motors and pumps, steer axle, counterweight, and frame
41
Some Questions to Help Judge a Load:
What is the rated load capacity of my truck? Is this load well within the capacity limits? Will the shape of this load affect my stability? Will the load affect my visibility? Do I need to split up the load? Do I need to drive in reverse? What hazards are along the route? ?
42
Some Questions to Help Judge a Load:
What turns will I have to negotiate? Are there ramps, slopes, rough ground or
obstacles? What about the destination? Can I get close enough? Can I pull straight in? Is the area free of overhead hazards like
power lines, pipes or ventilation equipment?
?

45
Maintenance of PITs
If defective, take out of serviceRepair by authorized personnel onlyRepair parts as safe or safer than originalDo not alter from manufacturer’s designRepair in designated location
46
Safe Parking Procedures
How and Where to Park?Attended ParkingUnattended ParkingParking on an incline
47
Lifting a Load Level the forks and slowly drive
forward until the load rests against the mast.
Do not slam a load into the carriage.
Lift the load high enough to clear whatever is under it.
Assess the stability of the load. Tilt the mast back slightly to a
traveling position.
48
Lifting a Load If there is another load in front of yours, lift
without tilting. Reassess load stability. Look over both shoulders to make sure it is
safe to move in reverse. If there are no obstacles to the rear, back out
slowly about one foot to insure the load will clear.
Back away to completely clear the load. Lower load to travel and reassess load stability.
49
Carrying the Load
Keep your vehicle under control at all timesKeep forks close to floor Maintain safe distance (3 vehicle lengths)Examine surfaces - safety and strengthSafe speed - a brisk walking pace
50
Carrying the Load Stay within the vehicle lanes. Look over both shoulders before you back up. Stop before raising or lowering loads. Tilt the load slightly back with forks low. Drive at a slow, steady pace. Observe speed limits and controlled Slow down for turns, sound your horn and stay
near the inside corner.
51
Carrying the LoadSlow down and sound your horn at
intersections and places with limited view.Drive in reverse if your vision is obstructed
by your load.Yield to pedestrians - always!!!
52
Carrying the Load
Never travel or turn with the load elevated.
Never drive up to anyone standing in front of a fixed object.
53
Carrying the Load Never allow anyone to stand on your fork or
lift people without an approved platform.
Never allow anyone to walk or stand under your forks, whether the forks are loaded or empty.
54
Carrying the Load
Surfaces you should avoid or be very careful on or around include: – Loose objects, bumps or uneven floors
– Rough surfaces
– Wet, oily or icy surfaces
– Railroad tracks and similar edges, which you should cross at a 45-degree angle whenever possible
55
Putting Down a Load
Square up and stop about 1 foot away from the loading area
Drive about 1/2 way into the unloading areaLower the load, assess alignment, stabilityLower forks slightlyLook over both shoulders and back out
slowly
56
Working with StacksThe higher you go - the less stable
your PIT and load
57
Working with Stacks
Remember these stacking rules:
– Set the top load squarely on the stack
– Never raise or lower a load unless you fully stop
– Never attempt to turn with your mast raised
– Approach load straight on and back straight out
– Make sure you have enough overhead clearance
– Watch for electrical lines, pipes, fixtures, sprinklers
58
Traveling on Grades
Stay well back from the edge Never turn around on the slopeDrive with your load on the uphill side!!!
– When loaded, drive up slopes with your load in front and drive down slopes in reverse.
– When the forks are empty, back up a slope and drive down it forward.
59
Working on Docks DOCK WORK CHECK SHEET
Check to make sure that wheels are chocked!
Check the front support on a trailer to insure it won’t shift.
Check to make sure the train car or trailer brakes as set.
Check the dock locks.
Check the deck capacity.
Check combined vehicle and load weight.
Check dock plate condition and position.
