When loading and unloading trucks with forklifts, several safety precautions should be followed. Always load/unload the machine on level and hard ground 1, 3, 4, 5. Use ramps, platforms, or embankments with sufficient width, length, slope, rigidity, and strength 1, 3, 4, 5. Ensure the surface is free of slippery materials like mud, dirt, water, snow, ice, grease, and oil 1, 3, 4, 5, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 20. Set the engine speed to LOW and the travel speed to LOW (1st) speed 1, 3, 4, 5. Do not use any attachments during the loading and unloading process 1, 3, 4, 5, 20. Use only the travel levers when the machine is on ramps 1, 3, 4, 5. Avoid making turns on the ramp to prevent tipping 1, 3, 4, 5. If using a platform or embankment, ensure it is wide enough for the machine and that the angle to the ground is 15 degrees or less 2, 6, 7, 8. Also, make sure the embankment is sturdy enough to hold the machine's weight and that the surface is level with the trailer bed 2, 6, 7, 8. Chock the trailer wheels before loading the machine 9, 10, 11, 12, 13, 14, 15, 16, 17, 18. It may be helpful to have a signal person to guide the loading and unloading process [1].
