    Default Does digging force equate to lifting force?

    By that I mean,

    If a backhoe has 4100 lbs of bucket digging force, would that equate to being able to curl the bucket and lifting 4100lbs of something, or would the lower dipper digging force limit that?

    No it does not.

    The 4,100 rating is misleading to the consumer
    for a number of reasons.


    The 4.100 pound rating could be either
    the relief setting for the specific function
    spool in question or the actual main relief
    cartridge of the tractor in question.


    The upper boom, dipper boom and the bucket
    digging cylinder all act independently.


    The upper boom only lifts and lowers both
    the dipper boom and digging bucket.


    The lower boom(dipper boom)only extends
    and retracts the bucket cylinder and bucket.


    The breakout force refers to the force required
    to break the grip of the material being excavated.


    The actual resistance encountered by the square
    area of the digging edge(s) and teeth if any
    encountered and overcome to excavate the
    compacted material, this itself is regulated
    by the normal system operating pressure and
    the over pressure relief setting.

    Also, cylinders are stronger extending than retracting (more surface area to push against.) All backhoes are built to extended on the dig stroke, not the lift. FELs are built to extend on the lift stroke.
