With that said, it’s worthy to note that the community’s risk profile can rapidly change due to weather conditions (e.g., Houston in 2017 after Hurricane Harvey made landfall three times in six days. On the other hand, both countries have many regions-and not just coastal areas-where roads and those bodies of water coexist.

and Canada certainly have areas where the interfaces between road networks and bodies of water are very limited, so the probability of a vehicle ending up in a river, stream or lake is practically nil. The primary factor that should help guide your department’s decision to consider underwater cutting tools should hinge upon your department’s geographical response area’s risk profile. “They may think, ‘Well, it's a three-year-old battery, I probably should replace it before something happens,’ and the battery could actually still be good,” said Crowbridge.An unexpected addition: Enter the underwater cutting tool Without knowing, a fire department could end up replacing perfectly good batteries, from a budgetary standpoint.

How many times has the battery been charged?Īccording to Crowbridge, with the program you can make more informed supply purchasing decisions.The software helps answer questions like the following: Another battery management feature is the diagnostic software program.įire departments can load the program on a desktop or notebook PC and review battery condition just by plugging the battery into the computer. LED indicators provide real-time feedback on tool temperature, maximum pressure reached, battery temperature, battery state of charge and battery state of health. Holmatro's battery diagnostic program analyzes the health of Pentheon Series batteries. Watch the speed and power of the Pentheon Cutter PCU50 versus the Holmatro CORE Cutter CU 5050 as both are used to cut the B-pillars of a late-model Volkswagen Golf automobile. One moment it may need a little more volume to give the working end of the tool some more speed, but then suddenly it may need a little bit more pressure in order to overcome an obstacle or a force, either a spread or a cut,” said Crowbridge. “Whatever the tool’s operator is trying to achieve, the tool itself will seek maximum peak performance to do that. The mechatronic pump uses both pressure and flow sensors to gauge its need to switch gears, or stages, continuously. So when a tool needs more force to cut the high-strength steels found in new model cars, there’s no significant drop in speed. This unique feature of the Pentheon line’s pump is made possible using Holmatro’s patented Stepless Speed Maximization system that automatically shifts a tool into higher speed than it would normally have, without loss of force, to deal with higher loads like those encountered with cutting the high-strength steels used in modern automobiles. More simply? Pentheon tools give you the highest possible speed over the full pressure range.Ī mechatronic pump is a mechanical pump that is electronically controlled to improve efficiency in its performance. And for the tool’s operator, it means that at any given battery capacity, a Pentheon tool is going to deliver a maximum flow at every pressure/force. The key element is a mechatronic drive system that precisely controls the motor and pump settings. Holmatro’s new Pentheon tools are more than just compact and powerful: They’re smart, too. “In addition, our engineers found a way to integrate the motor and pump, which allows for a slimmer and more compact tool design”, said Crowbridge. This resulted in a much smaller and lighter pump.

The engineers determined the number of plungers that are necessary in a pump, how big or how small they needed to be to get the flow and pressure needed for optimal tool operation. “Basically, they started with a clean piece of paper and they wrote down everything they wanted to have, whether it was currently achievable or not.” It can be as far-fetched as anybody can imagine,” said Crowbridge. We know what we want to achieve, and the engineers figure out how to make that achievable and design it to meet that criteria.”Īll hydraulic rescue tools have one thing in common: a sealed system that moves the prescribed volume of hydraulic fluid to achieve pressure in the tool.Ĭrowbridge described how Holmatro engineers were given the freedom to design from the outside in. (Photo/Holmatro)Īccording to Dan Crowbridge, Holmatro’s rescue and training consultant, the Pentheon Series’ advanced design started with the pump. Holmatro's Pentheon Series 360 carrying handle is made of a flexible high-grade synthetic polymer, which always returns into its original shape.
