I just realized that the arguments used on generative AI are basically the same as those used on NFT. They treat anything on the Internet as free to use and completely disregard the fact that copyrights exist for everything that someone made on the Internet.

Just because something exists in a public space doesn't mean it is in the public domain (free to use, copyright-free).

You'd think that's a no brainer but apparently not. And when they broke those boundaries, they just go, "Oops, it's already in the model/chainblock. You should have never upload them publicly/minted it first so you can keep the work to yourself."

sth sth demean human desire to socialize and part of that involve sharing things they are passionate about, aka the thing they had worked on to connect with other people. And taking it for yourself and disregard the original artist is insanely disrespectful sth sth

On tumblr (and a little bit of Twitter), there’s a lot of Jikook/Taekook shippers on here, I’m not one myself (if I ship, it’s platonic) and I have absolutely no problem with shippers and rpf enjoyers (just don’t be toxic about shit) but a lot of them are very angry about the fact that 3D is about a girl or doesn’t have any neutral lyrics, mainly because they are pretty insecure about the status’ of their ships and whether they are real or not. Not because they want the song to be more inclusive to people who listen to it, nope. Just because of ships. [Disclaimer: you’ll find that A LOT on tumblr, no matter which one of the 7 members posts. Tumblr shippers tend to believe that everything a member does HAS to be about the person they ship them with. E.g. if JK was to perform in Busan hypothetically, they’d be like “oh he’s performing there because Jimin is from there omg”. And don’t get me wrong, ship whoever and however you want, but come on now]

So yeah, tumblr mainly has hardcore shippers on here. Not that that’s bad, it can just get hectic sometimes.

The amount of 'Girl' in the lyrics threw me off as a genderqueer person but for them to be so delusional to be mad that hes not singing abt tae or Jimin(or anyone else) is crazyyy.

I feel like I'm learning so much about the Tumblr community LMAO tho I was seeing a glimpse of the shippers as I went thru the Jungkook tag last night. I will have to have the block button locked and loaded 🤺 too bad there's no chainblocks like Twitter, I used the fuck out of those lol

[qqchurch]

i wish the chainblocker still worked on twitter because good god i want to isolate this section away from my feed completely

"scared of simple death threats?" jesus christ on a pogo stick, i actually hope these guys experience even a fraction of the hate they're sending just because they're this entitled to whiteknighting an artist they're parasocial about

Optimizing Load Handling: The Role of Chain Pulleys in Modern Crane Design

In the world of heavy lifting, cranes are the undisputed giants—commanding skylines, dominating construction sites, and moving materials that would otherwise be impossible to handle. But inside these steel titans, there’s often an unsung hero doing the heavy work behind the scenes: the chain pulley.

Whether it's a compact jib crane in a factory or an overhead gantry system in a warehouse, chain pulleys are a vital component in many crane configurations.

What Is a Chain Pulley?

Before we dive into cranes, let’s start with the basics. A chain pulley—also known as a chain block or chain hoist—is a mechanical device used to lift, lower, or pull loads using a chain and gear mechanism. It works on the principle of mechanical advantage, allowing users to lift heavy objects with less effort.

The core components include:

Load Chain: Connects to the load and moves vertically.

Hand Chain: Pulled by the operator (or motorized in electric models).

Gearing System: Multiplies the input force.

Hook or Lifting Eye: Connects to the crane or lifting structure.

Chain pulleys come in manual and electric variants and are used in industries ranging from automotive and construction to warehousing and marine.

The Role of Chain Pulleys in Crane Operations

 While large-scale tower cranes or mobile cranes typically use wire rope systems, many other crane types—especially for small to medium lifting tasks—utilize chain pulley blocks as their primary lifting mechanism.

Common Crane Types That Use Chain Pulleys:

Jib Cranes (Wall-mounted or Pillar-mounted)

Gantry Cranes (Mobile and Portable)

Overhead Cranes (Bridge cranes in warehouses)

Workstation Cranes

Portable Cranes used in workshops and maintenance areas

How Does a Chain Pulley Work Within a Crane?

In a crane setup, the chain pulley typically hangs from the trolley or boom of the crane. The lifting chain is connected to the load, and when the hand chain is pulled (or the motor is activated), the internal gears rotate, pulling the load chain and lifting the object.

This allows for:

Vertical lifting of loads

Precise control over lift height

Manual or powered operation

Safe, controlled movement of materials

Especially in environments where space is tight or power access is limited, chain pulley systems in cranes provide an elegant, efficient solution.

Benefits of Using Chain Pulleys in Cranes

1. Cost Efficiency

Chain pulley blocks are significantly cheaper than wire rope hoists or hydraulic systems. They are ideal for small operations, repair shops, and businesses on a budget.

2. Precision Lifting

Thanks to the gear mechanism, chain pulleys offer smooth and accurate lifting, which is essential in delicate assembly tasks or when aligning heavy components.

3. Compact & Space-Saving

Manual and electric chain hoists are compact in design, making them perfect for tight workspaces or cranes operating indoors.

4. Low Maintenance

Fewer moving parts mean less frequent breakdowns. Chain pulley systems are easy to inspect, maintain, and repair compared to complex hydraulic setups.

5. Versatile Applications

From hoisting engines to lifting molds, chain pulley-equipped cranes can handle a wide variety of materials and shapes.

Applications of Chain Pulley Cranes

1. Manufacturing Plants

A wall-mounted jib crane with a chain pulley hoist is ideal for lifting machine parts, dies, and equipment in small-scale manufacturing.

2. Construction Warehouses

Portable gantry cranes with chain pulley blocks can help move heavy bags of cement, steel bars, or prefabricated panels in temporary setups.

 3. Automotive Workshops

Mechanics often use chain pulleys with engine hoists or small gantry cranes to lift vehicle engines safely and efficiently.

 4. Shipbuilding Yards

Marine-grade electric chain hoists on overhead cranes help lift and position propellers, engines, and other bulky components.

 5. Assembly Lines

Cranes fitted with chain pulleys offer repeatable, safe lifting in assembly processes, such as fitting gearboxes into machines.

Limitations of Chain Pulley Use in Cranes

While chain pulleys are incredibly useful, they do have limitations:

Slower Lifting Speeds compared to wire rope hoists

Limited Lift Height depending on the chain length

Not Ideal for Very Heavy Loads over 10+ tons

Manual Operation Can Be Fatiguing for frequent use

If your operation involves extreme lifting heights or very heavy loads, consider a wire rope hoist or hydraulic system instead. But for everything else—chain pulley blocks often offer the perfect balance.

Safety Tips for Using Chain Pulleys in Cranes

Safety is paramount in lifting. Here are best practices when using chain pulley systems in crane applications:

Inspect Before Each Use – Look for wear, deformation, or broken chains.

Check Load Capacity – Never exceed the rated WLL (Working Load Limit).

Use Proper Mounting – Ensure the chain pulley is securely attached to the crane’s hook or beam.

Wear PPE – Gloves, helmets, and steel-toe boots are essential.

Train Operators – Make sure only certified or trained personnel handle crane-lifting operations.

 Choosing the Right Chain Pulley for Your Crane

When selecting a chain pulley block for your crane, consider the following:

Load Capacity: Match the heaviest load you’ll lift

Lift Height: Make sure the chain length suits your crane’s reach

Frequency of Use: Go electric for frequent tasks

Environmental Conditions: Opt for stainless steel or galvanized units for outdoor or marine use

Compliance: Ensure the product meets safety standards (IS 3832, EN 13157, ASME B30.16)

While they may not be the flashiest component on a crane, chain pulley systems are the quiet powerhouses behind many lifting operations. From construction to manufacturing, chain pulleys enable cranes to do what they do best: lift safely, precisely, and efficiently.

So next time you see a crane lifting a load with ease, remember—it might just be the humble chain pulley doing the hard work in the background.
