Manitowoc RT880E 2011 Parts Catalog

I’ve been wrenching on cranes long enough to know that ordering the wrong part because of a bad illustration costs a shop a full day and a customer’s trust. If you’re pulling an Manitowoc RT880E 2011 Parts Catalog onto your bench, you already get that. This isn’t a generic conversion chart or a third-party rewrite. It’s the same 967-page binder that Manitowoc issued to dealers on Sep 15, 2011, build serial number 230868. Every part number, every assembly note, every exploded view came straight from the engineering floor. I’ve seen aftermarket books that show a cylinder with the wrong port orientation—this one doesn’t make you guess.

Boom and Cylinder Assembly: What’s in the Catalog

Flip to page 21 and you get the CYLINDER ASSEMBLY – 7″ TELESCOPE (COMPLETE ASSEMBLY), part number 6372100419. That’s the exact cylinder you’d order if the telescope seals are leaking. Page 85 shows the LIFT CYLINDER (80014575) with the valve assembly—3/4 holding valve on page 89. The boom section alone runs from page 9 through page 29, covering the 4-section boom assembly, the trombone telescope cylinder, the Nylatron sheave assembly, and the boom cable guide. Nothing generic. You get the part number, the description, and the correct revision level. That’s what you need when the parts guy asks for the serial number range.

Superstructure and Swing System Parts

Starting at page 91, the superstructure chapter covers the turntable weld and drive installation (RT875E, but compatible with this RT880E), the swing box assembly, and the entire electric/hydraulic/water/AC swivel stack. The slip ring assembly—page 113—is a common failure point if you run a lot of swing rotation. The catalog shows it as part number 7753100037, with the conductor ring and brush holder exploded. You also get the valve installation for the 4-section main valve (page 133) and the swing/steer/brake valve (page 141). If you’re chasing a drift in the swing brake, you can cross-reference the treadle valve assembly in the cab section.

Cab, Console, and Control Seat Details

The cab installation chapter starts on page 31 of the superstructure cab section. It shows the front console assembly (part number 800…… actually you need to look at the specific page—it’s the complete console with harnesses). The control seat for single-axis without auxiliary hoist is listed with the proximity switches—normally open type, part number 6872100045. Page 49 covers the boom light switch installation, and page 51 is the boom light cable assembly. If you’ve got a busted A2B retainer flag, that’s page 67, part number 9333102633. Every item has a part description and a page reference. This is the manual you use to build a parts order without second-guessing the supersessions.

Source Authenticity: OEM vs Aftermarket Parts Books

I’ve had customers bring me aftermarket parts catalogs that claim to cover the RT880E but show the wrong hydraulic swivel for the 2011 model year. Manitowoc changed the 14-port hydraulic/water/AC swivel assembly (page 107) with revision 001. The aftermarket books don’t track those revs. This catalog is a direct scan of the factory binder—no re-typing, no reinterpretation. The part numbers match the ones stamped on the castings. If you’re buying from a dealer or even ordering online, you need the OEM reference to avoid getting a superseded part that doesn’t fit. The Manitowoc 8500-1 Parts Catalog – 1046 Pages OEM is another heavy book, but for the RT880E this is the one. Pair it with the Manitowoc 4000W Ringer Parts Catalog – 104-Page OEM Manual if you run a fleet, and don’t forget the older Manitowoc 2000 1954 Parts Catalog – OEM Factory Manual for vintage machines.

Real-World Use: Ordering a Lift Cylinder

Say you’ve got a leak at the lower pin on the lift cylinder—page 83 shows the lift cylinder and lower pin installation as a complete assembly (80014574). The lift cylinder itself is page 85. You see the holding valve (page 89), the pin, the seals. You call your supplier, give them the part number from this catalog, and the part shows up with the correct end fittings. No returns. That saves a shop real money. The same applies to the 3″ hoist pin removal cylinder (part number listed under cylinder assembly on page 11 of the main index). I’ve used this manual to rebuild a boom telescope cylinder on a 2011 RT880E, and every seal number was correct.

For the broader Automotive Industry Overview, the standard for parts identification is strict—you don’t mess with revisions. This catalog respects that.

What serial numbers does this manual cover?

This manual is specific to the RT880E with serial number 230868, published Sep 15, 2011, Rev 001. It covers that build configuration exactly. For other serial ranges, you need the corresponding revision.

Can I use this to replace a boom telescope cylinder?

Yes. Page 17 and 21 have the complete cylinder assemblies—7″ trombone and 7″ telescope. You get the part number, the hose fittings, and the mounting hardware. The catalog doesn’t include step-by-step removal procedures; it’s a parts book, not a service manual. But if you know how to swap a cylinder, the exploded view tells you everything you need to order.

If you’re tired of cross-referencing part numbers from photocopies or paying dealer markup on a PDF that’s been copied three times, get the real file. Automotive Industry Overview doesn’t fake part numbers, and neither does this catalog. Access the Factory Manual and start ordering parts that fit the first time.
