Trapezoidal Bucket - Komatsu PC220LC -8 Operation & Maintenance Manual

ATTACHMENT GUIDE

TRAPEZOIDAL BUCKET

Use the trapezoidal bucket when digging trapezoidal ditches in
fields. By installing the variable plate, it is possible to excavate
three angles of ditch slope face (45°, 40°, 38°).
The position of installation of the variable plate is different for
each ditch slope face angle (45°, 40°, 38°).
Digging Work
Operate the boom, arm, and bucket so that line A of the side plate
of the bucket is always perpendicular, then carry out digging.
Horizontal calculation plate B is welded to the bucket pin hole
portion, so when digging, operate so that the plate is horizontal
during the digging operation.
Ditch slope face 45 degrees
Use the bucket only or install the variable plate using the ditch
slope angle holes, and use the method above for digging.
