BRAKE PERFORMANCE CURVE
Method of using graph
Example: Downhill distance: 1500 m (4921 ft)
Travel resistance -11% [grade resistance -13%, rolling resistance 2%]
Load: 32 tons for HD325, HD325(4WD sepecifications), 40 tons for HD405
Obtain the maximum permissible speed and the transmission speed range from the graph when traveling downhill
under the above conditions.
1. Use the brake performance graph for the downhill distance of 1500 m (4921 ft).
2. Starting from point (A) which corresponds to the overall weight of the machine, draw a perpendicular line down.
3. Take the point where it crosses the line for travel resistance -11% as (B) and draw a horizontal line.
4. Take the point where it crosses the performance curve as (C), and draw a perpendicular line down. Take the
point where this line crosses the travel speed scale as (D).
5. The following information can be obtained from this procedure.
From point (D): Maximum permissible speed = 28 km/h (17.4 MPH)
From point (C): Speed range = F4
This maximum permissible speed is one guideline determined from the retarder brake performance, so on an actual
jobsite, determine a safe downhill travel speed (below the maximum permissible speed) to match the conditions of
the jobsite so that the retarder brake oil temperature gauge is always in the green range.
