Grove Manitowoc National Crane RT9150E Technical Manual

A crane that’s off the book on load charts because someone slapped a counterfeit spec sheet in the cab gets people killed. That’s not dramatic—that’s Tuesday in a heavy-equipment yard. This 28-page product guide from Grove Manitowoc National Crane is the only source I trust for the RT9150E. You need the factory load moment limits, the anti-two-block system data, and the exact counterweight configurations. Aftermarket printouts are garbage. I’ll say it flat: if you’re running a 150-ton (USt) crane on a jobsite without the official specs, you’re gambling with iron and bodies.

Specifications on Page 4: What You Get

Page 4 lays out the superstructure and counterweight options. Standard counterweight is 39,000 lb (17,690 kg), hydraulically installed and removed. Optional heavy-lift package adds 24,000 lb (10,886 kg), bringing total to 63,000 lb. You also get the six-section MEGAFORM boom with TWIN-LOCK pinning system—boom length 12.9 m to 60.0 m (42.3 ft to 197 ft). Maximum tip height 209 ft. The manual lists the manual offset bi-fold extension (11–18 m, offsets 0°, 20°, 40°) and the optional hydraulic swingaway extension. Both stow alongside the base boom section. If you’re setting up a pick and carry, you need the dimensions from page 7 and weights from page 8 to decide transportability.

Load Charts: 39,000 lb vs 63,000 lb Counterweight

Load charts start on page 12 for the 39,000 lb counterweight, page 16 for the 63,000 lb setup, and page 20 for pick-and-carry configurations. Each chart is specific to the RT9150E’s boom length, angle, and radius. Don’t mix them. If you’re running the heavy-lift package, you use the 63,000 lb charts—no exceptions. The manual also includes rigging charts (page 21) and load handling procedures (page 23). The anti-two-block system and load moment indicator are described on page 4: graphic display with audio-visual warning and control lever lockout. Work Area Definition System lets you pre-select safe working zones.

Working Ranges and Rigging Charts

Boom elevation comes from a single double-acting hydraulic cylinder with an integral holding valve—range from -3° to 78°. Working range diagrams on page 9 show radius vs height for every boom section. Rigging charts on page 21 tell you the exact sling angles and hook load capacities. If you’re using the bi-fold swingaway extension with inserts (8 m and 6 m), those specs are in the manual too. Do not attempt to lift without verifying the offset setting (0°, 20°, or 40°) because the load moment changes significantly.

Audience Fit: Who Needs This Manual

This product guide is not a service manual—it won’t walk you through an engine teardown. It’s a technical reference for crane operators, riggers, and equipment owners who need the factory load charts and dimensions for setup. If you’re a DIY mechanic working on the RT9150E’s hydraulic systems or the TWIN-LOCK boom pinning mechanism, you’ll pair this guide with the full service manual. But for daily operation, site planning, and counterweight configuration, these 28 pages are the only source that matters.

Source Validity: Why Aftermarket Won’t Do

I’ve seen third-party load charts that round off values and skip the 63,000 lb counterweight table entirely. That’s a lawsuit waiting to happen. This manual is direct from Crawler Crane manufacturer’s documentation—same spec sheets that ship with the crane. The TWIN-LOCK system details, the MEGAFORM boom data, and the dual-axis proportional controllers are all factory-verified. If you need the official torque specs for the outrigger box bolts? Not in this guide (it’s a product guide, not a service manual). But for load handling, rigging, and dimensions, this is it.
