  • Page 18 Section I - SAFETY PRECAUTIONS (cont'd) SAFE STEERING LOAD, GVWR, GAWR, & GCWR (cont'd) 1.1 CHASSIS LIMITATIONS (cont'd) Furthermore, information may be available from your chassis manufacturer that tells you to maintain a specific amount of weight on the front axle of your chassis for safe steering. If the chassis manufacturer recommends that you should maintain more weight on your front axle than safe steering formula indicates, then you should adhere to the manufacturer’s recommendation. 2. Do not exceed the GVWR (Gross Vehicle Weight Rating) of your chassis when you are towing a load. Exceeding the GVWR of your chassis can affect its braking and handling.
  • Page 19 Section I - SAFETY PRECAUTIONS (cont'd) SAFE STEERING LOAD, GVWR, GAWR, & GCWR (cont'd) 1.2 CALCULATING SAFE STEERING LOAD (cont'd) A simple formula for calculating the maximum lifted load for safe steering is shown below. It is based on the requirement for maintaining one-half the unladen steering weight. This formula has been used by the towing industry for many years and has proven reliable for determining the maximum lifted load for safe steering under good towing conditions as stated above.
  • Page 20 Section I - SAFETY PRECAUTIONS (cont'd) SAFE STEERING LOAD, GVWR, GAWR, & GCWR (cont'd) 1.2 CALCULATING SAFE STEERING LOAD (cont'd) You can use pounds and inches or centimeters and kilograms in your calculations. If you use kilograms instead of pounds and centimeters instead of inches, the safe steering limits will be in kilograms. Do not mix pounds and kilograms nor inches and centimeters in the same calculation.
  • Page 21 Section I - SAFETY PRECAUTIONS (cont'd) SAFE STEERING LOAD, GVWR, GAWR, & GCWR (cont'd) 1.2 CALCULATING SAFE STEERING LOAD (cont'd) FIGURE 1.2 FIGURE 1.3 3.

OTHERWISE, THE TOWING LIMITS WILL...
  • Page 22 Section I - SAFETY PRECAUTIONS (cont'd) SAFE STEERING LOAD, GVWR, GAWR, & GCWR (cont'd) 1.2 CALCULATING SAFE STEERING LOAD (cont'd) 5. Multiply the result of step 4 by the wheel base. 6. Divide the result of step 5 by the overhang. The result is the maximum load that the truck can lift and maintain safe steering.
  • Page 23 Section I - SAFETY PRECAUTIONS (cont'd) SAFE STEERING LOAD, GVWR, GAWR, & GCWR (cont'd) 1.2 CALCULATING SAFE STEERING LOAD (cont'd) In the above example, 7,437 pounds is the maximum safe steering load that should be lifted by the wheel lift at its usual towing position. You can calculate safe steering loads for other positions by substituting the overhang distance.
  • Page 24 Section I - SAFETY PRECAUTIONS (cont'd) SAFE STEERING LOAD, GVWR, GAWR, & GCWR (cont'd) 1.3 CALCULATING GAW, GVW, & GCW (cont'd) EXAMPLE OF CALCULATING REAR AXLE GAW: This example uses numbers from the previous example to show the types of information to use: 4,250 1/2 the front axle weight + 7,437 maximum load for safe steering) + 10,000 unloaded rear axle weight 21,687 GAW of rear axle. See Figure 1.5.
  • Page 25 Section I - SAFETY PRECAUTIONS (cont'd) SAFE STEERING LOAD, GVWR, GAWR, & GCWR (cont'd) 1.3 CALCULATING GAW, GVW, & GCW (cont'd) EXAMPLE OF CALCULATING GVW: This example uses numbers from the earlier example to show the types of information to use: 8,500 unloaded weight of the front axle + 10,000 unloaded weight of the rear axle + 7,437 maximum load for safe steering 25,937 GVW. Refer to Figure 1.5. Thus, the GVWR of the truck chassis used in the example should be at least 25,937 pounds.
  • Page 26 Section I - SAFETY PRECAUTIONS (cont'd) SAFE STEERING LOAD, GVWR, GAWR, & GCWR (cont'd) 1.3 CALCULATING GAW, GVW, & GCW (cont'd) Remember, these are only examples. You must use the actual weights and dimensions of your tow truck when calculating GAW, GVW and GCW. Weights for most vehicles that you might encounter when towing can be obtained from various trade sources and consumer report magazines.
