Boom Frame:
The collapsible boom frame of the structure is made of welded steel pipe and mounted on the front of both sides of the pontoons.
Boom (ladder) winch:
• traction up to 11 tons on the first layer
• speed 0.15 m / min
• drive from an electric motor with a power of 4 kW
Hydraulic washing out:
The water wash tip is a removable part of the suction pipe. It has 4-6 nozzles of various diameters under different slopes, which allows the funnel to erode in clay soil more than the diameter of the suction pipe around the tip circumference. Unit power 15 kW, flow 80 m3/ hour at a pressure of up to 80 m
Cutter unit:
The cutter ripper is mounted on the milling shaft with a screw thread. Cutter drive from a 20 kW hydraulic motor, adjustable speed from 0 to 50 rpm. The hydraulic motor is mounted on the cutter.
The front end of the cutter device provides with a front plate and a removable suction tip of a special shape with a nominal surface area of about 125% of the surface of the suction pipe. The suction pipe is also mounted to the cutter mechanism. The wall thickness of the suction tip is 10 mm, comes with a mesh, the passage is slightly less than that of the pump capacity. The diameter of the cutter is 800 mm, the weight of the unit is about 500 kg.
The cutter is designed for cleaning vegetation from a reservoir, such as reeds, roots of reeds, algae and small shrubs (diameter up to 2 cm), as well as soil up to category 4th .
Side winches
To rotate the dredger, side winches with electric drive in front of the cab are installed.
Side ropes pass through a pulley on pontoons and are connected to anchors.
• number of winches 4 pcs.
• pulling force to 8 tons on the first layer
• speed 0.25 m / min
• drive from an electric motor with a capacity of 2.2 kW
For maneuverability of a dredger: Side Winch Anchors – 4. Each anchor comes with a buoy and a hoisting rope
For the power network, a three-phase insulated power distribution system with a voltage of 380 V, frequency 50 Hz is used
For a lighting network in a dredger, a two-wire insulated power distribution system with a voltage of 220V and a frequency of 50Hz is used.
For control and signaling networks, as well as emergency lighting, a two-wire insulated 24VDC power distribution system is used.
