1) The basic version of the dredger with "walking" piles and lifting the trunk of hydraulic cylinders.

 With the help of piles, each of which is equipped with two hydraulic cylinders and a depth control system, the dredger can independently enter the water, move around the water area and leave the water. In the case of towing, the piles are piled forward, the mast is back, and the clearance for passage under bridges is 3.5 m.

2) The basic version of the dredger with "walking" piles and lifting the trunk with a winch through the portal.

With the help of piles, each of which is equipped with two hydraulic cylinders and a depth control system, the dredger can independently enter the water, move around the water area and leave the water. Suspension of the trunk on the cable reduces the likelihood of mechanical damage to the trunk. In the case of towing, the piles are piled forward, the mast is back, the bow portal is forward or backward, and the clearance for passage under bridges is 3.5 m.

3) The basic version of the dredge with "walking" piles, lifting the trunk of hydraulic cylinders and arrows for anchors.

With the help of piles, each of which is equipped with two hydraulic cylinders and a depth control system, the dredger can independently enter the water, move around the water area and leave the water. Arrows 12m long allow the dredger to independently anchor. In the case of towing, the piles are piled forward, the mast is back, and the clearance for passage under bridges is 3.5 m, but dismantling of columns and arrows is required.

4) The extended version of the dredger with vertical piles and the lifting of the elongated trunk winch.

The dredger is equipped with a classic system of vertically moving piles. Lifting of piles is carried out with the help of hydraulic cylinders, the capture of piles is carried out with the help of a strangulation from a cable. Suspension of the trunk on the cable reduces the likelihood of mechanical damage to the trunk. Towing under bridges with a height of less than 4m requires the collapse of the nasal gantry, as well as the dismantling of the hydraulic cylinders of the piles and the piles themselves.
