What Is a Hydraulic Rescue Tool?
Sometimes you need a lot of power to get a job done. This is definitely true for tools that need to cut, bend, or snap steel and other metals. Fire departments and other organizations frequently need to do just that—cut and bend heavy metals—in their life-saving duties. When they come across these situations, they need a tool that can offer power and that is also easy to use.
Hydraulic rescue tools can cut, pinch, spread and ram. These tools use the power of hydraulics, the compression of liquids, to generate the power they need to get through the toughest materials. These tools replace less efficient methods, such as using a circular saw, which may take too long to operate or cause additional safety concerns. For example, using a saw to cut metal may cause flying sparks— something you might like to avoid at the scene of a car accident where there may be exposed fuel or fumes.
When people think about hydraulic rescue tools, they typically picture the Jaws of Life®. Jaws of Life is actually a brand of rescue tools trademarked by the Hurst Performance company. Hurst was the first to develop and market these hydraulic rescue tools. Nowadays, there are several companies who offer these life-saving machines.
What are Hydraulic Rescue Tools Used For?
Rescue tools are commonly used after a vehicle accident. In certain kinds of car accidents, the vehicle is damaged in such a way that one or more people are trapped inside. This could put them in further danger due to the presence of gas and the possibility of a fire or explosion. The person inside the trapped car may need immediate medical attention. Perhaps a piece of the vehicle is pressing or pinning their body. It’s even possible that the car needs to be lifted off them completely. In any of these cases, a fast extrication (that is, getting the trapped person out of the car) is essential. These are the types of scenarios where a hydraulic rescue tool comes into play. These tools free trapped persons by either cutting, spreading or pinching. There are also hydraulic rams.
Hydraulic cutters are the biggest, meanest, sharpest pair of shears you have even seen. They have metal blades (often made of hard steel) that can cut through even the most difficult metals. The hydraulic power that operates them puts forth an amazing amount of pressure, so they can chomp away at anything they’re applied to. They open to varying degrees depending on the size and model.
Sometimes cutting isn’t the fastest or easiest way to get the job done. Frequently in these cases, emergency personnel use a spreader. A spreader looks like two large metal fingers pressed together. They come together into a narrow tip at the end that can be inserted into narrow spaces. The tool then uses hydraulic power to spread the fingers, pushing apart the metal panels. These are frequently used to pop a whole door off of a vehicle. They are also used to lift (the same way a jack would) or spread apart other wedged metals.
Spreaders, of course, can only separate as wide as the spreader mouth is designed to open. In some cases, firefighters or other rescuers will need to push something apart further than the spreader can offer. This is when they might use a ram. An example is when a dashboard of a car is pressing down on a victim’s body. The ram is inserted between the dash and the floor and opens the space up enough for a person to be freed.
Many companies that manufacture rescue tools offer a multi-tool—one tool that can perform more than just one function. This is most commonly a spreader/cutter combination. These tools are perfect for spreading seams to better expose the metal that needs to be cut.
A Must for Emergency Workers
It’s not every day that a person needs to be rescued from a wrecked car, a fallen elevator or other emergency scenarios. However, on those occasions, there is no substitute for a rescue tool that works fast, safely and efficiently. Hydraulic tools offer the power needed to contend with vehicles that are continually being manufactured to be stronger. These tools could offer the power and performance needed to save a life.
