rak-40 drain cleaning machine

The rak-40® drain and sewer cleaning machine – the professional tool for day-to-day sewer work

The rak-40® is regarded as the all-round workhorse among drain cleaning machines. The basis for that is the external clamping jaw system, which lets the jaws be changed in a matter of seconds. The external jaws also make room for a continuous, one-piece drive shaft inside the machine, through which the cable is guided. Neither moisture nor dirt can travel along the rotating cable into the interior of the rak-40®.

Thanks to this design, the rak-40® runs on permanently lubricated ball bearings that make later re-greasing unnecessary. The motor built specifically for the rak-40® offers high starting and breakdown torque, which keeps the machine steady in operation. The shaft driving the cable turns at 670rpm, placing the rak-40® among the high-speed drain cleaning machines – an advantage in particular when working with chain knockers.

The drive lever on the longitudinal axis can be locked in place and then serves as a carrying handle, which makes the machine easier to move.

The rak-40® is used in pipes from 30 to 150mm with 16mm and 22mm cables. The optional adapter drums and adapter hoses also allow 8mm and 10mm cables to be run, opening up smaller pipe diameters as well.
