®RPM II Design

Front Ring moved rearward:

Less Weight

provides larger capacity without increased weight

RPMII vs. Conventional

Lower Trunnion for better control and dumping



®

CGPull Point

Dig Angle

Increasing Pull to Tip Geometry



® Reverse Spade Lip

As bucket engages the cut, the rear of bucket lifts slightly, pulling the center teeth out of the material.

With the force concentrated on the corner teeth, there is less resistance and bucket penetrates better.



® RPMII Features

Cast Front End Ring for structural integrity, low

maintenance

Integral Trunnion cradles bucket, resulting in faster,

cleaner dumping

Reverse Spade Lip penetrates easier, resulting in faster fill

with S145H122K Adapter and 122K Series Points

Stiffener plates reinforce casting-to-plate transitions

Lower Trunnion• Smooth, quick dump

• Better Recovery

• Vertically Hanging Bucket

• Reduced Carryback

Dragline Buckets & Rigging

•What does a dragline do?•Removes overburden from the top of:

• Coal (main use)• Phosphate• Bauxite

•Also used to dig aggregate from underwater gravel pits.

Coal

Seam



®

•Why are draglines used?

•When conditions…•Are relatively flat•Have homogeneous seams•Have an abundance of Resources

…Draglines are the lowest cost to dirt move.

Chain Terminology



®

• Chains are sold in strands• A strand is usually made up of:

• Intermediate Links – the links making up the main portion of the chain strand

• Stud End links – an end link with a hole, usually bushed, that accepts a pin to lock the chain in place.

OR• Pear End links – an end link that is pear shaped, with

extra wear metal. A shackle fits through a pear link to fasten the chain in place.

• Some chains have STEP UP Links, where the size of links near the end is bigger than the intermediate links.

• Strands can be:• Opposite Plane – a strand with an even number of

links, resulting in the end links being 90 degrees apart in orientation.

• Same Plane – a strand with an odd number of links, resulting in the end links being in the same orientation.

Chain Terminology



®

• We use functional descriptions

400SS20

Refers to the chain size, in thiscase 4 inch

Refers to the end links, either “S”tud or “P”ear

Refers to thetotal # of links between the end links

Chain Terminology



®

• Examples:• 412PP20 – 4.5” chain, Pear links on each

end, 20 links in between the end links• 300S312P312-9 – would consist of (7) 3

inch intermediates, (2) 3.5” step up links, a 3.5” Stud link on one end, and a 3.5” Pear end link on the other end.

• Field Terminology• 7 & 2 or 7 +2 – Means 7 intermediate

links and 2 end links.

Chain Terminology



®

• Common Inquiries• “I need a quote on a socket”

• ESCO utilizes Long BowlTM sockets• Typically will accommodate 3 different rope sizes• Different sockets have different bowl angles

Dump sockets have a tighter angle for better grip.

Drag sockets have a less tight angle for easier removal

• Most wedges are specified by 1/8” rope increments

• Example: W25A; divide by 8, wedge is 3-1/8” rope

• There are oddballs, however, so be sure to check the catalog.

Chain Terminology



®

• Catalog Usage for Problem Solving• Tabs identify the major sections

• First determine what area of the bucket they are talking about: Lip, Hitch, Trunnion, Anchor, etc.

• Titles across the top identify the part name• Key things to help you when searching:

• Pin Size - #1 Key thing for many parts• Male or Female (Clevis or solid end)• For shrouds, identify the lip width and nose size, and find

that section.• For dumpblocks, identify the diameter to start with.

• Maintenance Pieces - Available on Steel Network


Chain Terminology



®

• “I am looking for a replacement bushing for a PDEXXXXX link.” • “I need a pin for a CEXXXX link.”

Solution: For these two, go to the spec book first. If you can’t find it there, go to agile for the drawing. The notes on drawings sometimes call out “Mating Parts”.

• “I have a part number A14358 but it doesn’t come up.”

Put a “C” in front of this and try in Oracle. Old PMID’s sometimes didn’t utilize the first letter.

• “I need a CE9847A#5 but there are none available. Can we use a CE9847A#3 instead?”

Send this to Product Coordinator. The #’s on the back of parts designate minor variations, such as different pin sizes. Product Team will research and advise you what options may exist.

Other Common Questions



®My Expectations of You

• Email communications for RFQ’s• Include Customer name

• Gain comfort using PMID’s• They are the language your customers use.• Seven digit numbers are foreign to Products Groups

• No dumping – if you need help with someone, please call, but stay on the line.

• Learn the basics of the spec book.• You should expect this from your dealers and your

DM’s as well.
