3 Bucket leveling limit device
When the bucket is in the unloading state, if the bucket
manipulating handle is pulled backwards to the extreme
rear position, the bucket manipulating handle will be stuck
by Bucket Receive holding magnet and will be held at the
extreme rear position (the bucket manipulating handle will
not return back to the middle position even you release
your hand), and the bucket will be rotated backwards all
the time; when the bucket reaches the limit position, the
bucket leveling limit switch is actuated, the Bucket Receive
holding magnet is de-energized and loses the attractive
force, and the bucket manipulating handle will automati-
cally rerun to the middle position under the force of spring
and the bucket will no longer rotate. In this case, lower the
arm. When the bucket contacts with the ground surface,
the bucket bottom is flush with ground surface. When the
bucket manipulating handle is again pulled backwards to
the extreme rear position, the bucket manipulating handle
will not be stuck by Bucket Receive holding magnet (it will
return back to the middle position under the force of spring
when you release your hand) because the Bucket Receive
holding magnet is de-energized all the time due to the
Limiting and Holding function of the bucket leveling limit
switch. Only when you push bucket manipulating handle
forwards and the tilting of bucket (unloading) exceeds the
bucket leveling position, can the bucket leveling limit switch
be reset and the bucket auto leveling function be restored.
At this time, if the bucket manipulating handle is again
pulled backwards to the extreme rear position, the bucket
manipulating handle will be held at the Extreme Rear Posi-
tion.
The bucket manipulating handle does not have holding
function when it is at the front position. When the bucket
tilts forwards from the maximum bucket receive angle to
the unloading angle, you need, at all time, push the bucket
manipulating handle in ahead(bucket manipulating handle
will return back to the middle position under the force of
spring when you release your hand), which will not stop
even when the bucket passes the leveling position.
When shoveling and loading, you should fully use arm
lifting limit, arm floating device and bucket leveling limit de -
vice, which will effectively reduce the labor intensity, thus
improving the comfort of operation.
