Underwater Chainsaws: What They’re Used For (And Why They Cost So Much)

Underwater chainsaws are hydraulic powertools that use compressed air to rotate a bladed chain. As with common chainsaws, that chain is affixed with blades to chop via wooden, and a few may even deal with concrete, metallic, and plastic. They do not all the time have the identical rip-roaring energy or portability as gas-powered chainsaws, however they’re invaluable for underwater purposes. Their waterproof encasings are higher outfitted for moist circumstances, so additionally they serve nicely within the mud and rain. Some fashions even have diamond-grit enamel to stop kick-backs and jams while you’re slicing away at extra-hard supplies. 

Underwater chainsaws are primarily used for slicing the picket pilings of docks, bridges, and different submerged buildings. It sounds area of interest, nevertheless it’s really fairly widespread. The water is a robust catalyst for rotting wooden and eroding docks, so fixed upkeep is vital. 

To use an underwater chainsaw, all you want is a appropriate air compressor and a hose to hook it up. Most customary air compressors will do, however diesel-powered compressors are normally extra moveable in comparison with electrical ones. Many underwater chainsaws have additional security options. For instance, they usually have cooling programs, powered by both water or oil. Options with hand guards and chain brakes forestall damaged chains from taking off a hand. Furthermore, you’ll be able to anticipate interlocking security triggers to assist decrease accidents.

These Tires Have Retractable Snow Chains You Don’t Have To Put On

“During normal driving, the shape memory alloy located inside the wheel is compressed into the shape of the letter ‘L’ and does not contact the road surface,” Hyundai says. “When the driver activates the function, an electric current is applied, causing the shape memory alloy to revert to its original profile: the material forms a ‘J’ shape, pushing the module out of the tire to make contact with the surface, improving grip, stability, and safety on snowy roads.”

One added function prevents any alloy spokes from breaking ranks and protruding earlier than their time (resulting from a worn-out tire). If the floor of the tire is worn out, the driving force is signaled to switch it so the automobile would not begin grinding like a Flintstones automotive with a foul tire. Hyundai says the expertise is patent-pending in each South Korea and the U.S., and plans to think about mass improvement after additional testing. While prompt tire chains will probably be a welcome reduction, clearly, it is solely a matter of time earlier than a button causes the tires to shoot out fireplace and soften the ice, or simply hover above it.

You Should Avoid These Products When Cleaning Your iPhone

Apple advises against using compressed air to clean your iPhone, but they don’t explain why. It turns out that the use of compressed air for cleaning purposes is a somewhat complicated issue. In certain areas of Canada and the United States, using highly compressed air for cleaning in work environments is actually illegal. Additionally, many commercial canned air products contain dangerous solvents instead of air. When these products are misused, they can spray out liquid which could be disastrous for your electronics.

Specifically for iPhones, the risk lies in damaging the internal components of the phone. If you use compressed air to clean the speakers and other openings of your iPhone, there is a possibility that you could blow out the microphone. A Reddit user shared their experience of only picking up static from the microphone after using compressed air.

People often consider compressed air as a suitable option for cleaning electronics because it doesn’t involve water. However, the high-pressure air can still displace or damage delicate parts, and it can turn debris into harmful shrapnel. It’s advisable to follow Apple’s recommendation and avoid using canned air on your iPhone.
