Cross drive loading
Always set the wheel loader facing at a right angle to the stock-
pile. After digging in and scooping up the load, drive the
machine straight back in reverse, then bring the dump truck in
between the stock pile and the wheel loader.
This method requires the least time for loading, and is extremely
effective in reducing the cycle time.
V-shape loading
Position the dump truck so that the direction of approach of the
wheel loader is approx. 60 degrees from the direction of
approach to the stockpile. After loading the bucket, drive the
wheel loader in reverse, then turn it to face the dump truck and
travel forward to load the dump truck.
The smaller the turning angle of the wheel loader is, the more
efficient the operation becomes.
When loading a full bucket and raising it to the maximum height,
first shake the bucket to stabilize the load before raising the
bucket. This will prevent the load from spilling to the rear.
Precautions when piling up loads
When forming products into a pile, be careful not to let the rear
counterweight come into contact with the ground.
Do not set the bucket to the DUMP position when piling-up
loads.
REMARK
As far as possible, do not use the transmission cut-off function
during screaping-up operation. This will prevent the machine
from rolling back.
