  27. Operating a Lift Truck • Preoperation Inspection • Operating a Lift Truck • Loading/Unloading • Traveling • Ramps and Railroads • Docks • Parking • Battery Charging Leo Korthofopleidingen

  28. Preoperation Inspection • It is your responsibility to make sure your forklift functions properly • It requires preoperation inspections • You must be sure equipment is maintained Leo Korthofopleidingen

  29. Walk Around • Forklift properly disengaged • Forks down, key off, neutral gear, parking brake on • Left/right side • Tire condition, tight lug nuts, no debris around axle, overhead guard is solid, no debris behind the mast • Front • Forks in good shape, fork pins in place, backrest solid, mast & chains greased, hoses in good shape • Rear • Counterbalance bolt is tight, radiator clear of debris Leo Korthofopleidingen

  30. In the Seat • Nonmoving checks • Gauges, lights, horn, back-up alarm, blinking warning light, operate the tilt & lift mechanism, check the parking brake • Moving checks • Put on the seat belt, check the running brakes, check the steering • Look for oil or water leaks on the floor Leo Korthofopleidingen

  31. Operating a Lift Truck 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 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 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 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 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 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 Leo Korthofopleidingen

  38. Parking • Lower the forks • Set gear to neutral • Set the parking brake • Turn off the key Leo Korthofopleidingen

  39. Propane Refueling • Propane is a combustible, compressed gas • Propane leaks are detected by: • Distinct odor • Hissing sound • Frost on fittings • PPE: gloves, safety glasses Leo Korthofopleidingen

  40. Battery Charging • Inspect battery connectors for damage • No smoking in battery-charging area • Immediately clean up electrolyte spills • PPE includes face mask, acid-resistant gloves, and an apron Leo Korthofopleidingen

  41. The forklifttruck Leo Korthofopleidingen

  42. Blz 19 Components of a Forklift Truck* *One of the most common types of powered industrial trucks 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 Leo Korthofopleidingen

  44. How a Forklift Mast Works • single mast • Mast with 2 parts • Mast with 3 parts Leo Korthofopleidingen

  47. Page 21 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. . 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 Leo Korthofopleidingen

  49. Stability of Powered Industrial Trucks • Definitions • General • Basic Principles • Stability Triangle • Longitudinal Stability • Lateral Stability • Dynamic Stability Leo Korthofopleidingen

  50. Page 25 Stability Triangle - Figure 1 Vehicle Center of Gravity (Unloaded) B A Center of Gravity of Vehicle and Maximum Load (Theoretical) C 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. Leo Korthofopleidingen
