Stanley Hydraulic Hammers

Everybody knows what pile drivers are. Pile drivers are those big noisy construction machines that drive big steel beams into the ground for construction of skyscrapers, and other tall buildings. Their noisy as all get out, and they make the ground shake for blocks around. Well, hydraulic hammers are closely related to those pile drivers, and could actually considered their little brothers. Hydraulic hammers haven't been around for as long, but they provide much of the same brute strength for smaller jobs. A combination of pneumatic, diesel, and hydraulic technology, is what makes them work.

Any discussion on the workings of hydraulic hammers, would be incomplete without an understanding of fluid dynamics. Fluid dynamics is simply, the the study of the how fluid flows, taking into account it's environment, how it is contained, and the pressures exerted on it. Understanding how the fluid moves, and controlling that movement, is what makes it possible for devices like hydraulic hammers to work. In order to move that fluid, some sort of pumps, a motor, and some array of piping is employed. By pressurizing that liquid, the raw energy can be diverted to a mechanical device to do whatever job needs to be done. Tasks, like driving piles, breaking up concrete, or other construction work. By pressurizing the liquid, and then releasing it in a controlled manner, the hydraulic hammer is able to trasfer that pressure and force to whatever job it is required to do.

Without going into some rather long and boring formulas, the principles of fluid dynamics, and some rather sophisticated mechanical engineering allow a small amout of force to be converted into a very large output of power. It's basically quite possible for a good hydraulic hammer to convert two pounds of pressure into a walloping two thousand pounds of pressure. That's a great return on your power investment.

That amount of power is one of the reasons why hydraulic hammers are so good at a variety of mechanical, demolition, manufacturing, and construction type tasks. When employed as a pile driver, the hydraulics of the hammer often serves a dual purpose. It works both to dig dirt and drive piles into the earth. When considering the size of hammer necessary to do the job, a number of technical specifications need to be taken into account. When all considered, they provide a sum total of what the hammer is capable of. Ram weight and stroke, hammer weight, pressure, and motor size all factor in.

Hydraulic hammers often come with many interchange end pieces, which can be changed depending on the task at hand. Tearing up a road would use a asphalt cutter, but if concrete is your target, than a good moil point would be more appropriate. To compress loosely packed soil, you would attacher a tamper to the business end of your hydraulic hammer.

While hydraulic hammers may seem noisy, and cumbersome to handle, their really not. Compared to other construction and demolition devices, their actually much quieter, and less disruptive. Vibrations hammers like jack hammers are much noiser, and more likely to damage other structures and objects in the work area.
