You can have all the procedures in the world but they only serve to reduce the risk, they will never make something 100% safe. As soon as you release the harness, there is a risk that the person can fall to the ground, you reduce that risk by providing things like fall arrest harnesses and edge...

Not off the top of my head, I could have a look when I'm next in work but the way things are going that could be quite a while.

Could be, that would make it the same as the backup engine used on Kumali at Flamingoland. Evacuation is dangerous, that's why it should only ever be done as a last resort. You have to go through a whole list of options to recover the train before you can even consider evacuation away from the...

Indeed, evacuation is a last resort only if the train can't be moved by other means.

It's hard to tell from the picture, a good view of the rocker cover or switch panel would give a good clue.

Pretty much every coaster has an engine designed to either drive a system such as the lift or a generator to provide limited power.

Pretty much, it provides a load for the drive to work against and all the energy is bled off as heat. In theory, any braking resistor can be replaced by a capacitor or battery to store a portion of that energy for later use. It is just a matter of wether or not it is worth the expense...

You are correct, in order to start the ride, the system needs to see a low water level so that the boat can be chucked up the tower a couple of times. The gates that control the water level would be set up so that if there is a failure, the water gets dumped back into the channel...

Judging by how well it maintains speed around the track, it looks like Vekoma have finally ditched tapered roller bearings in the wheels and gone for good ole ball bearings. I'm seeing hints of Intamin in that chassis and wheel assembly design and I'm liking it. Now if only I could persuade...

They could indeed have a dry mode added that basically ignores the water level and gate sensors and alters the overcurrent threshold and braking curve for the LSM's to allow for the drive having to provide all the braking power. As far as extra equipment is concerned, the only thing that would...

The short answer is it will not work without water in the channel. The rides control system is expecting to see certain water levels at specific points during the ride cycle. If the reported level is not what the system is expecting then the ride shuts down with a fault displayed. That being...

Parts are usually standardised even across different models. But this only applies to the design currently in use as designs are always being updated to take advantage of new technology and feedback from customers. As time goes on and designs evolve, new parts made to the latest specification...

If a part is worn beyond the specified limits, it will be replaced regardless of how old the ride is. Otherwise you end up with problems that will be a little more serious than a bit of roughness. The problem for older rides like Nemesis is that replacement parts get more expensive per part and...

That bit did raise an eyebrow but it would be sort of correct as newer designs would mean having to re-tool in order to produce parts for older stuff. It would work out cheaper for B&M in the long run to offer a complete upgrade in order to reduce overall manufacturing costs.

Ye....... that's probably for the best. I've had the (mis)fortune of providing an engineering review of some of their designs and I established that safety standards do exist in China, but noone seems to know what they are. I don't think that's fair on B&M as they can only sell a ride if a...

I would be suprised if more than a couple of track sections get replaced. At a guess I would say a new lift chain and guides, new sprockets and bearings, new main drive and gearbox. New station drives and gearboxes. New brake units with most of them replaced by magnetic brakes as Nemesis chews...

They also use Banner for some optical proximity switches too. https://www.bannerengineering.com/th/en/products/sensors.html Might even find a few Sick sensors too https://www.sick.com/gb/en/

A lot of companies tend to advertise jobs internally for a week or two first before making the advert public. This is definately true of Merlin as they would put job adverts up in staff areas for about 2 weeks before the vacancy went on the website. The jobs weren't limited to that particular...

This is why I think LSM systems will dominate for a long time to come. Even flat rides with regular rotary motors now have variable frequency drives that have the option to feed braking power into a capacitor for later use, rather than sending it through a resistor grid to be bled off as heat...

This. A ride can run for months on end flawlessly but when it comes to your visit it decides to throw a hissy fit over something silly, almost as if the ride suddenly doesn't like the way you have the train lined up.....
