Talk:Twistlock

kock
I assume, that the original name for a twistlock is kock. For sure, it can be confused with cock. So the word has no influence in the english language. Jörg Lietmeyer I think the word is used in the netherlands, too. Jörg Lietmeyer —Preceding unsigned comment added by 217.184.5.154 (talk) 19:03, 8 December 2009 (UTC)

How does Container stacking work?
Do containers have twist locks on their upper corners? What is a container which is stacked on or above another container locked to? --174.234.79.20 (talk) 15:30, 24 May 2012 (UTC)

Clothing
What about such fasteners on clothing, e.g. File:Beavertail Wetsuit.jpg? --AVRS (talk) 10:31, 21 September 2012 (UTC)

Accidental Unlocking
Is there a mechanism that prevents the twisting part from untwisting? If so, how does that work? Danielx (talk) 05:16, 9 June 2013 (UTC)

Locking/Unlocking tool?
The article does not describe how the locking head is rotated. There must presumably be tools or mechanisms to do this, and they must engage the locking head in some manner. Could somebody add a clear explanation, preferably with a good line diagram or photo? Reify-tech (talk) 12:57, 20 December 2013 (UTC)
 * No, actually. Push, twist, release.Dovid (talk) 20:26, 9 January 2014 (UTC)
 * Push with what? Twist with what? I'm sure this is obvious to somebody who has operated a twistlock, but can anybody find a picture or diagram understandable by the rest of us? Reify-tech (talk) 00:46, 10 January 2014 (UTC)

Looking back through his talk page, Dovid appears to be one of those editors who jumped straight into reviewing and the bureaucratic side of Wikipedia without actually having any aptitude for communicating information. He isn't going to be around for very long with responses like that and Wikipedia doesn't need more people like him. How is the head turned, when the container is in the middle of a 3x3 stack? -Ashley Pomeroy (talk) 20:16, 11 January 2015 (UTC)
 * Please stop being a first-class, arrogant twit. It was one thing when you wrote like that on my talk page, which is moderately private. It is quite another in this shared conversation page. You seem to be one of those editors who delight in claiming to be elite, especially to your betters. As with the user talk page entry, here's a reformulation of your remarks:
 * Non-twit version: Too bad Dovid gave such a terse answer. I left a note on his talk page, perhaps he'll come back and explain. Looking back at his history, he's done a lot of editing, in addition to some administrative work. While he hasn't done as much in the last year, perhaps with my nice invitation, he'll come back to this.
 * Twit version: I'm an idiot who has been on WikiPedia for over 10 years, and yet I still don't understand the Archive bots. Since Dovid only has a handful of entries on his user talk page, I guess that must be his entire history... there's no way he can have been an editor for a decade himself like I myself like to boast about. And those entries relate to fairly narrow areas of the WikiPedia world, so he must not be so worldy as to have contributed significant original text to thousands of articles. Only I can claim such a throne, me, me, me. I think I shal insult him on his talk page and here, because it just seems like the right thing to do.
 * By the way, the answer to the original question from over a year ago really is as simple as I stated. If it is connected (inserted and locked), then grab its housing with your hand, push in, twist counterclockwise until it stops, pull out. If it is not inserted yet, then insert it, push until you meet solid resistance, twist clockwise, and release your hand; give it a little tug to assess whether it properly seated. How does it work? That was beyond the scope of the question, but here goes. It depends somewhat on the exact type of twistlock plug. The most basic configuration has L-shaped blades, which project out of the plug. The "head" of the L is attached to the plug frame, the "stem" projects out, while the "base" of the L at the other end of the stem is the curved part. The corresponding holes have the same curve. The holes actually have a longer channel with the same curve behind them; the holes expose about half the channel, but the other half is concealed/blocked by the face of the receptacle adjacent to the hole. Push in, and the base of the L blade, being in the channel, can move freely. The stem of the blade can also move freely, because the hole it is in, while not as long as the channel underneath, is still wide enough for the stem to move through its curve. All 3 or 4 blades run along the same circle, so the plug is balanced along the curves of the receptacle, and can be twisted, so long as those heads clear the channel covers that edge the holes. (The channel cover is really the whole face of the receptacle - everything except the holes.) In some versions, there is also a center pin that helps align the whole structure, and allows it to more perfectly rotate about that center pin. In some there is also a spring, to add tension and make it harder to accidentally engage or disengage the plug from the receptacle. Also, in many cases the L shaped curved blade has a lip at the end of the "base," so that once locked, the spring pushes the plug out a bit, and the lip catches on a projection within the channel. The plug now cannot be twisted without pushing it furthe rin again, against the force of the spring.


 * You're welcome. Dovid (talk) 04:21, 12 January 2015 (UTC)
 * , whether your answers are short or long, please could I remind you to be WP:CIVIL in your communication with other editors. —Sladen (talk) 10:35, 12 January 2015 (UTC)
 * , you are correct, but did you take a moment to read the scurrilous post I was responding to? I'm not saying it is cool to respond to unprovoked, unfounded personal attacks on oneself in kind. Nevertheless, I find it odd that you singled out my response, and not Ashley's. Dovid (talk) 22:32, 13 January 2015 (UTC)

Load Capacity
The load capacities quoted are incorrect. The tensile Minimum Breaking Load is 500 kN and the Shear Minimum Breaking Load is 420 kN. Compressive capacity is estimated in US National Institute of Standards and Technology Report 6557 - Strength Evaluation of Connectors for Intermodal Containers. That report finds a minimum capacity for being compression loaded and still being operable of 445 kN Subsea (talk) 20:24, 13 December 2014 (UTC)

Twistlock patent
The book The Box has a diagram of the all-important patent 3,027,025 on page 189. MountVic127 (talk) 06:03, 5 April 2024 (UTC)

The first mention of the Twistlock is on page 74. MountVic127 (talk) 06:07, 5 April 2024 (UTC)
