OPERATION
2-64
12.17.6 LOADING OPERATIONS
Select the method of operation which will give the minimum amount of
turning and travel and provide the most efficient method for the jobsite.
WARNING
Always keep the working area flat. Do not turn suddenly or apply
the brake suddenly when traveling with a raised load.
These actions are dangerous.
It is also dangerous to drive the bucket at high speed into a
stockpile or pile of rocks.
NOTICE:
If the tires slip, the tire life will be reduced, so avoid slipping or
spinning of the tires during operation.
Avoid excessive shaking of the bucket.
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 approximately 60E 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 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 carrying out piling-up
operations.
