32
24-4-2015 Leo Korthofopleidingen 31 Operating a Lift Truck
33
24-4-2015 Leo Korthofopleidingen 32 Operating a Lift Truck Only trained, authorized operators Immediately report forklift-related accidents Seat belts must always be worn No person should stand under elevated portion of lift truck Forklift controls operated only from driver’s seat Never block exits or emergency equipment Smoking is not permitted
34
24-4-2015 Leo Korthofopleidingen 33 Loading/Unloading Before raising a load, understand: Approximate weight of the load Location of the load’s center of gravity Inspect load for stability, projections, damaged pallets before lifting Restack unstable loads Never place weight on the back of a lift truck to increase its capacity Towing always done from rear towing pin
35
24-4-2015 Leo Korthofopleidingen 34 Traveling Always look in the direction of travel Keep body inside the cage When moving, the mast must not be raised Sound the horn Operate at safe speeds When turning, watch rear end swing Clearance under overhead installations
36
24-4-2015 Leo Korthofopleidingen 35 Traveling Avoid loose objects or holes If load blocks view, travel in reverse Never carry passengers Pedestrians always have the right-of-way Safe distance from edge of ramps or docks Never eat or drink No stunt driving or horseplay
37
24-4-2015 Leo Korthofopleidingen 36 Ramps and Railroads Never turn on a ramp On ramps the load should be upgrade Ascend or descend ramps slowly Railroad tracks are crossed diagonally Never park within 8 feet of the center of railroad tracks
38
24-4-2015 Leo Korthofopleidingen 37 Docks Inspect the dock plate Check the trailer floor condition Trailer wheels are chocked Nose of the trailer is supported by the tractor or a fixed jack

24-4-2015 Leo Korthofopleidingen 43 Forkliftmast Mast The mast is the vertical assembly responsible for lowering or raising a load. A forklift mast is made up of interlocking rails necessary to provide lateral stability. These rails are guided by rollers or bushings. Hydraulics Forklift masts consist of metal plates used to move materials and are hydraulically driven. Hydraulics refers to the transmission of power via the use of pressurized fluid --- in this case, oil. Hydraulic cylinders that link directly to the forklift motor drive the mast, enabling it to lift, lower or tilt a load. The pressurized oil drives the cylinder piston to move in strokes, or linear motion. The mast is typically operated via a lever in the cab, or the area in the forklift used to house the operator and forklift control components

24-4-2015 Leo Korthofopleidingen 47 Verschillende hoogtes. Hefhoogte = maximum forkhight maximale heffing van de vorken boven de vloer Afzethoogte= max.height to pick up and/or put down loads =Maximale hefhoogte – 25 cm Vrije hefhoogte= freelift of freelift, vrije werkruimte zonder uitschuiven van de mast Doorrijhoogte= Driving hight Hoogste punt van mast of kooi met de last of lege vorken op 15 cm van de grond. Bouwhoogte= Overall height is het hoogste punt van de truck met de vorken op de grond. Page 21

24-4-2015 Leo Korthofopleidingen 48 Lastdiagram Korte omschrijving Op een heftruck moeten een typeplaat en een werklastdiagram aanwezig zijn op een plaats waar ze voor de heftruckchauffeur duidelijk en afleesbaar zichtbaar zijn. Bij het heffen van lasten spelen onderstaande zaken een rol: Totale hoogte van de uitgeschoven hefmast Maximale vorkhoogte Totale hoogte ingeschoven hefmast Maximale vrije heffing Gewichtsverdeling en de afmetingen van een last

24-4-2015 Leo Korthofopleidingen 49 Stability of Powered Industrial Trucks Definitions General Basic Principles Stability Triangle Longitudinal Stability Lateral Stability Dynamic Stability
51
24-4-2015 Leo Korthofopleidingen 50 A B C Vehicle Center of Gravity (Unloaded) Center of Gravity of Vehicle and Maximum Load (Theoretical) 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.

24-4-2015 Leo Korthofopleidingen 69 Quiz 1.If your forklift has a rearview mirror, looking behind you is not necessary. True or False 2.Name two of the three ways to detect a propane leak: _______________, _______________ 3.Describe the four items that must be completed prior to driving your forklift into a trailer. 4.If a load blocks your vision, it is OK to raise the load while moving to see under it. True or False 5.Preoperation inspections are done only because OSHA says we have to do them.True or False
71
24-4-2015 Leo Korthofopleidingen 70 Quiz (cont.) 6. Attachments reduce capacity by increasing the load center and adding weight. True or False 7.Minimum PPE items required when refueling a propane tank are ___________, ____________. 8.The most important differences between a forklift and a car are weight and steering.True or False 9.Name at least one condition that when combined with turning sharply may cause a tipover. 10.Pedestrians have the right-of-way only while in designated pedestrian lanes. True or False
72
24-4-2015 Leo Korthofopleidingen 71 Quiz Answers 1.False. You must always look behind you before backing up. 2.Hissing sound, distinct odor, or frost on fittings. 3.Chock the wheels, support the nose of the trailer, inspect the dock plate, check the trailer floor. 4.False. Never drive with the load up. Drive in reverse when the load obstructs forward vision. 5.False. Inspections are also done so that the operator can prevent mechanical failure accidents and because the company needs to prove compliance with OSHA’s requirement.
73
24-4-2015 Leo Korthofopleidingen 72 Quiz Answers (cont.) 6.True. Attachments are heavy, and they cause the load center to move away from the forklift. 7.Gloves and safety glasses are the minimum PPE required. 8.True. There are many differences, but the most significant are weight and steering. 9.Hitting a pothole, carrying an off-center load, getting a flat tire, having a raised & tilted back load, or being on a ramp. 10.False. Pedestrians always have the right of way.
