SCRAPER OPERATION CONTINUED
C AU T I O N
Always return ejector to rear of bowl after dumping load. This reduces the chance of
hydraulic cylinder damage due to bouncing when traveling at higher speeds.
10. Return ejector to rear of bowl and close apron.
11. Return to cut area at highest practical travel speed for job site conditions.
12. On subsequent dumping/spreading passes, consider straddle dumping:
a. Leave a gap between 1st and 2nd dumping passes that is less than distance between tires.
b. On the third trip, unload between 1st and 2nd passes, at a spread depth GREATER THAN previous passes;
this will leave a new ridge.
c.
Repeat until desired depth of spread is achieved.
Picking Up Windrows
0005
A windrow is a row of excess material that must be removed. Typically, a dozer or motor grader creates the wind-
row, pushes it off to the side, and leaves it to be loaded into a dump truck by a wheel loader. When working with
other construction equipment, the scraper should NOT be used as a dump truck. Instead of bucket loading with an
excavator, wheel loader, or dozer use scraper to pick up the windrow.
Pick up windrows as follows;
a. Approach windrow.
b. Partially open apron.
c.
Lower cutting edge until it just clears the surface.
d. Load bowl.
e. Repeat as required until windrow is removed.
