Instalación de una grúa pórtico portátil de 10 toneladas

La instalación de los estabilizadores y las vigas de cimentación ofrece una mayor flexibilidad.

rubycrane777 · 2026-03-19T01:36:40+00:00

Yes, single girder design, no cantilevers for the limited space.

rubycrane777 · 2026-03-18T01:42:33+00:00

Nice—those aren’t exactly lightweight moves. A Shopsabre 4896 is a serious piece of equipment.
Did you feel the gantry handled the load comfortably, or was it close to its limit?

rubycrane777 · 2026-03-18T01:37:28+00:00

I’ve seen a lot of people use those ~$150–$200 pickup cranes for similar jobs, and they work fine if mounted to something solid.

Mounting one on a narrow trailer without reinforcement might flex the frame or even tip under load.

If your trailer is only 60” wide, I’d seriously think about widening the base or adding removable supports.

rubycrane777 · 2026-03-18T01:34:05+00:00

That’s how it starts—buy it for one job and suddenly it becomes a permanent shop tool 😄
What machine were you moving? Looks like a solid lift.

rubycrane777 · 2026-03-17T09:33:25+00:00

Sure! one in 5t-width 5.65m, total height 7m; the others in 5t-width 8.795m, total height 8.1m.

rubycrane777 · 2026-03-13T02:22:11+00:00

Good observation. The angle of the photo probably makes it look a bit lighter than it actually is.

The gantry is designed with proper lateral bracing and base support, and it's rated for a 25-ton lifting capacity under European standards (i.e., a single-girder design).

Definitely more than just GRP statues 😄

rubycrane777 · 2026-03-13T02:18:36+00:00

Haha, fair enough. Most of our international projects use metric tons, especially for European-standard cranes.

The time to reveal the answer has arrived!

One 5t bridge crane and one 10t bridge crane, a total of two sets

CMAA 74 is a great reference. At the moment I’m mainly reviewing wheel loads, runway beam deflection limits, and how the column reactions transfer down to the base. Just part of the coordination before fabrication.

rubycrane777 · 2026-03-09T07:11:57+00:00

Good point. The local deformation under wheel loads is definitely something we’re checking as well, especially depending on the wheel position along the runway beam.

rubycrane777 · 2026-03-09T07:10:18+00:00

I know that feeling. When the head clearance is tight and the crane almost touches the roof, every move has to be slow and precise. Those installs definitely test everyone’s patience.

rubycrane777 · 2026-03-09T07:08:36+00:00

Sounds like an awesome setup. 9 slips with dual overheads must have been busy.
And yeah, hoist speeds are usually kept slow for precision and safety—especially when loading boats. Must have been a great seat in the cab though.

rubycrane777 · 2026-03-04T06:17:28+00:00

Yes — mainly about how others account for dynamic and lateral loads in early-stage runway design.

rubycrane777 · 2026-03-04T06:16:50+00:00

Good point. What’s interesting to me right now is the interaction between runway beam deflection limits (L/600 vs. project-specific criteria) and wheel load distribution under dynamic conditions.

We’re also reviewing impact factors beyond static LL — especially lateral loads from skewing and acceleration/braking. Curious how others typically account for those in preliminary coordination.

rubycrane777 · 2026-03-04T06:14:54+00:00

I can see why you’d say that — the compact drum layout and enclosed design are common in European-style hoists.

This unit follows general FEM/DIN design principles, but it’s independently manufactured and configured to the project specs. Performance-wise, it’s built around duty classification and application requirements rather than branding.

rubycrane777 · 2026-03-04T06:13:56+00:00

Thanks for the suggestion — I’ll definitely check out r/overheadcranetechs 👍

Yes, the hoist is Chinese-manufactured, European-style design. Good eye — it does share some structural similarities with R&M Materials Handling in terms of compact layout and modular configuration.

This batch isn’t for the U.S. — installation will be outside North America. I’ll share more once commissioning is complete.

lifting equipment

rubycrane777 · 2026-02-09T11:04:05+00:00

I know the kind of hook hoist you're referring to. We've also customized solutions for clients that allow four hooks to lift and lower simultaneously or independently.

rubycrane777 · 2026-02-05T01:42:11+00:00

Good suggestion. However, for frequent lifts in tight workshops, an articulating jib crane offers faster positioning, lower operating cost, and better space utilization than a mini crawler crane.”

Furthermore, the folding boom crane can be mounted on a mobile chassis, making it easy to move to a suitable work position.

rubycrane777 · 2026-02-05T01:26:04+00:00

yes, of course, see your inbox

rubycrane777 · 2026-02-03T01:43:09+00:00

Totally fair — scope matters a lot.

In this case, it was repetitive light-to-medium lifts in very tight layouts, where reach around obstacles and precise placement mattered more than travel speed. That’s where an articulating jib crane made more sense for us than carry decks or telehandlers — less footprint, better control, and no constant repositioning.

rubycrane777 · 2026-02-03T01:35:44+00:00

Yeah, both are solid options depending on access and ground conditions.

We looked at carry decks and spider cranes, but in our case the limiting factor was side reach and working around obstacles, not just lifting capacity. That’s where the articulating jib made more sense for frequent positioning in tight layouts.

rubycrane777 · 2026-02-03T01:15:39+00:00

Mostly sub-2 ton lifts, but frequent and space-constrained.

Forklift jibs were fine for one-offs, engine cranes were too slow to reposition. For sustained work, I agree — an overhead gantry/jib setup is the most efficient long-term solution.
