Who is jackhammer

Wider bits don't penetrate very quickly, so using them often takes longer. Regardless of the style, it's vital to avoid going too deep into the rock. It's extremely easy to get the bit stuck, meaning you'll be taking an unscheduled break until you figure out how to loosen it.

Sharp bits are critical for maximum efficiency. When bits become dull, both the man and the machine have to work much harder to crush and crack the rock.

That means you should sharpen the bit regularly, and the harder the rock, the more often you should check the bit. Most jackhammers are used to work straight down or on an incline.

It's possible to hammer horizontally, but because of the tool's immense weight, this task requires two people, or better yet, a jackhammer stand that supports the heft without human help. Overhead hammering requires smaller jackhammers or machine assistance. Jackhammers are heavy, powerful tools, and they take a toll on the human body.

The weight and vibration inherent to jackhammers tends to wear out even hardened construction workers. Some companies regularly rotate workers on jackhammer duty to save their strength and spare them the constant work of controlling such powerful machines. Adequately rested workers are less likely to make mistakes or hurt themselves. Jackhammers are renowned and often despised for the racket they create.

That's why many modern jackhammers include silencer boots to dampen their noise output. Yet these rock-breaking marvels still rate as one of the noisiest tools, often subjecting workers to decibels, which is louder than a jet engine at takeoff.

As such, hearing protection is necessary protective equipment for both the jackhammer operator and anyone nearby.

Excessive vibration from jackhammers can also damage the human body. Even with vibration dampening components, the relentless violence exacted upon the concrete below comes back on the operator to some degree.

Too much vibration can cause fatigue, headaches, stomach issues, insomnia, and muscular and skeletal issues. Medical researchers link power-tool vibration to Raynaud's phenomenon, which affects blood vessels in the extremities. After too much jackhammer vibration exposure, people who suffer from this condition wind up with poor circulation in their hands, which might even turn white from lack of blood.

Jackhammers often create clouds of dust, and sometimes that dust can be dangerous. For example, breaking up concrete pavement can release crystalline silica , which is known to cause lung cancer. To keep dust levels down, workers can attach a hose that sprays a mist of several ounces of water per minute, wetting the work area for a safer breathing environment.

Shrapnel is not unusual, so it's a really good idea to wear long, tough pants and long-sleeved shirts. Steel-toed boots are also recommended. And because jackhammers are heavy, some have optional lift-assist technology that pushes the tool upwards out of the ground, making it much easier to move around in the work area.

Although jackhammers make quick work of many substrates, they aren't the right tool for every demolition job. On some sites, buried gas or electrical lines might lurk beneath the surface, just waiting for a jackhammer's hefty bite to suddenly make the local emergency room a lot more exciting. It's easy to point out the dangers of jackhammers. They are powerful machines with potential for serious destruction. But, of course, destruction is the whole point.
