Hydraulic Emergency Door Opener (with CP-700 Manual Pump)

Text in the video: Text in the video: Today we're showing you this fire door opener for emergency situations. The KMQ-890 is a split-type hydraulic tool. Split-type hydraulic tools must be used with a hydraulic pump. That is, there are three pump options for this spreader. The first one is this compact hand pump. It weighs about 4.5 kilograms. With this pump, you'll need to pump more intensively. The second is a large, ten-kilogram one. It pumps very quickly. I'll demonstrate now. Just a few pumps and it's out very quickly. With the smaller pump, you'll need to work a little more and apply more effort. So, these are the two manual pump options. And the third option is the electric version, with a portable electric pump, 220V, 50Hz. It operates simply with these buttons. They are available as complete kits: the tool comes with the small pump, with the large pump, or with the electric pump. If this part gets damaged, the spreader itself can simply be replaced. You just purchase a new one and that's it. Now I'll show you how it connects. First, unscrew these plastic plugs. I'll demonstrate it using the large hand pump. Unscrew the plugs. Then, preferably, when you're finished working, screw them back in to keep the connections protected. It doesn't just slide on and screw in. You need to push it in firmly first. You can see that, right? There's a spring-loaded mechanism here. You need to push it inward and then screw it in. Of course, make sure it's tightened securely and pressed in firmly. That's how it locks into place. Very simple and quick. These are oil-filled connections. For operation, the OFF position is clockwise. And that's it. Let's take a look. We pump the handle and see how quickly it extends. And that's it. It has 9 centimeters of extension and a force of 8 tons. 8 tons of force, with 9 centimeters of extension. Now retract it. Set it to the counterclockwise position. Turn this one here. And that's it. If you're working with the smaller pump, you'll need to make more pumps like these. It will be slower, but the advantage is that the pump is much more compact. Now, the electric version. The hose connects in exactly the same way. Plug it into a power outlet. And here we have two buttons: ON and OFF.
