Impact wrench Kraft: features, characteristics, comparison
Content
On the driver's forums, the Kraft wrench gets good reviews: “indestructible”, “reliable”, “long-liver”, “faithful companion”.
A wrench is a universal tool that can be found in any car. Most often, drivers use it when beading tires and replacing tires. But wheel nuts - large and stuck - are not easy to unscrew by hand. Mechanical devices come to the rescue, one of which is a hand-held Kraft wrench made in Taiwan using German technology.
Types of nutrunners
The gradation of tools for installing and disassembling hardware is very wide. According to the type of drive, wrenches are:
- Hydraulic. The drive in the device is a hydraulic pump.
- Electrical (network). The devices are powered from a conventional 220-volt electrical outlet.
- Pneumatic. Powered by compressed air from a compressor.
- Rechargeable. Power source - battery.
- Manual ("meat grinders"). They are driven by the force of the hand of the master, and the planetary gearbox (multiplier) inside the device increases the applied force by 60-80 times.
Devices are also divided into shock and unstressed, angular and straight.
Technical specifications
The design of the manual device is simple: a planetary gearbox is placed in a cast steel case, the main element of which is the drive shaft. At one end of the shaft there is a handle for rotating the mechanism, at the other there is a connecting square, to which heads are attached to work with fasteners. A manual impact wrench is attached to the object by means of a movable stop foot.

Turning the handle sets the multiplier in motion. The gearbox increases the torque to several hundreds and thousands of Nm. Threaded connections of any complexity lend themselves to such an effort.
When buying tools, pay attention to the following characteristics:
- The gear ratio of the multiplier. Most often it is 1:56. This means that for 56 rotations of the handle, the fastener will turn 1 time. This is a very slow unscrewing speed, but sufficient to undermine a rusty bolt. Next, you need to switch the device to a second, increased, speed, or continue unscrewing it with your hands or with an ordinary wrench.
- Torque. It is chosen based on the type of tasks: a torque of 200 Nm is enough to work with nuts in passenger cars, 1000 Nm and more for trucks, special equipment.
- Connecting square. In choosing the size, they are guided by the heads of the fasteners with which to work. The most popular square is half an inch, but heavy trucks require a 1 inch connection.
