I'm working in a port zone in Brazil , and now I know how twistlocks really work. I didn't know that there are different positions of twistlocks on contêineres. This video was very useful for me, thanks a lot.

Good stuff can't believe I've never seen a single one of these on all the ships I've worked on but the fact you need a special tool to unlock them is ridiculous

A ideia foi muito boa, porém deu certo por pouco tempo. As castanhas sofrem todo o impacto no momento em que o contêiner é embarcado no navio e essa castanha tem uma vida útil,toda tem e quando chega a hora ela geralmente não tem reparo e precisa ser substituída. Na ponta do lápis esse modelo da MacGregor deve sair bem mais salgado que as castanhas que são mais simples e mais comuns de se encontrar nos navios mais novos. Inclusive os navios da maersk,em que quando saíram do estaleiro com essas castanhas do vídeos,hoje usam as tradicionais que precisam ir travadas até a última altura. A ideia de não precisar usar uma vara mais longa para destravar as pilhas acima da quinta altura no inicio otimizava a operação por não precisar usar a gaiola,como ele mostra no vídeo. Mas com o tempo as castanhas foram deixando na mão.

The only problem with this twistlock they have alot of moving part and twistlock don't get maintenance and after 3 year they don't work

You still run into problems with these, especially when the guts get blown out and they aren't springy anymore (you see it slot with these types especially the floor stackers)

Do these belong to the ships and have to be put back on board after unloading the containers they were attached to?

I'm a laser they are new and they are allready falling apart and some times they are in open mode and they remain lock . When use as deck shoes don't open when loading container. Maybe just bad quality materials

This is why you don't see countless pics if containers, at the shipping docks with the ship about to sink, because the containers are falling off the ship from both sides.

I'm a lasher ship is only 4 year old and its my worst nightmare

Tks

I think cma rank number one with the thick wire twistlock

muy maja la pletina muy maja la barra de abrir ,pero no he visto como se abre a 8 alturas

if I worked on the sea, I'd worry if they'd auto unlock in particulally rough weather.

Does this mean that whenever the containers are to be loaded/unloaded at a bay from/on the container ship, people that work there have to unlock the containers from each other manually to be lifted up by the crane? And also be locked manually when the containers are beeing loaded on to the ship from the crane?

But how are the twistlocks on the sides of the containers that are cramped up to other containers operated? I don't see enough space there to lock or unlock them.

Working at container terminal, didn't see worse idea than these type MacGregor locks. Time consuming and waisting ,unsafe ispecialy when need pulling over at 5 high position with longer poles. That is step back not forward.

5th minute of this video is showing container chassis/frame for twist lock installation; I am asking if anyone can help me to find supplier who can provide same.

They auto-unlock? So what prevents that from happening at sea??
