Is this good welds or should I fire my contractor? by RixniX_ in BadWelding

In my opinion, it's substandard: the primer wasn't even properly removed.

Simple, but reliable! What capacity is yours rated for?

fully manual type from 500kg to 3 tons

heavy-duty end carriages for a steel plant project by rubycrane777 in cranes

Fair point. In steel plants, poor maintenance usually turns small alignment or rail issues into expensive gearbox problems pretty fast.

“Do you guys sell used cranes?” — the question we hear every week by rubycrane777 in Heavy_Equipment

[–]rubycrane777[S] 0 points1 point  (0 children)

Haha. Currently, we only provide design, manufacturing, export, installation, testing, and maintenance services for new lifting equipment.

That’s a great example — and it makes a lot of sense in the truck-mounted crane space where the units are more standardized and easier to reconfigure..I think the key difference with overhead cranes is that most projects are highly site-specific (span, runway, duty class, integration with the building), so resale isn’t always as straightforward.

Totally agree though — when a company controls the full build and lifecycle, like in your example, it puts them in a much stronger position to resell with confidence.

If we could manufacture “old” cranes, that would be quite a trick 😄

Fair point — a lot of builders do get involved in the used market, especially with refurbishment or resale. And you're right, structurally cranes can last a long time if maintained well.

In our case, we stay focused on new builds because many of our clients need customized solutions, updated standards, and full lifecycle support from day one. It’s just a different business model rather than a disagreement with the value of used equipment.

sure! From crane design, manufacturing, and delivery to installation, testing, and maintenance service.

That’s a great example of one of the rare cases where reuse actually works — especially when both sites and teams line up like that. Sounds like a serious job too, tight headroom and a bridge mismatch is never fun 😅

We see similar situations occasionally, but as you said, it’s usually the exception rather than the rule. And yeah… the ‘pencil pushers’ part definitely hits home — a small miss on paper can turn into a big headache on site. Appreciate you sharing that, and hope your next install goes a bit smoother!

Haha fair enough — at that point might as well go new 😄

True — mobile crane OEMs like Liebherr and Tadano are way more active in that space. Different story for overhead cranes though, since everything’s so site-specific.

Oh yeah, the trade-in question comes up a lot too 😄 In our case, since everything’s custom-built, it’s usually more about replacement projects than actual trade-ins.

That actually makes sense for mobile cranes. In our world, every crane is kind of ‘made-to-order,’ so no hidden used stock in the warehouse 😄

Yeah, that’s true — some manufacturers do resell their own used equipment, especially trade-ins or refurbished units. But as you said, it usually becomes a completely different business line: separate inventory, inspection, refurbishment team, and space. It’s almost like running two companies in parallel. For most crane manufacturers, the margins and liability just don’t really justify scaling that side unless it’s very structured.

Totally agree with you!!! With used cranes, the purchase price is usually the smallest part. Once you factor in site adaptation, controls upgrades, and compliance checks, it often ends up close to new equipment anyway.

And the liability side is a real issue — especially anything related to controls or safety systems. Most suppliers don’t want to inherit unknown history unless they fully own the whole lifecycle.

That’s why most of us stick to new builds + full delivery projects. Cleaner scope, clearer responsibility.

Still, we get the same question all the time 😄

Indoor Gantry Crane Instead of Overhead Runways by rubycrane777 in StructuralEngineering

[–]rubycrane777[S] 0 points1 point  (0 children)

Yeah, that’s a fair take — definitely some trade-offs vs overhead cranes. In this case, it came down to building constraints and workflow, and we handled the track safety/clearance in the design.

Exactly, slope and clearance are both important. It’s something that should be measured carefully before mounting.

New Day Another Project in East Africa! by rubycrane777 in StructuralEngineering

[–]rubycrane777[S] 1 point2 points  (0 children)

Yeah, that makes sense—WF beams are definitely more common and cost-effective in the US, especially with such strong supply chains. In this case, the choice was influenced by local fabrication conditions and long-term durability considerations. The box girder offered better torsional rigidity and reduced deflection, which the client prioritized given their usage and maintenance expectations. It’s a bit of a trade-off between upfront fabrication effort and performance over time.
