FLOATING SELF-PROPELLED PILE DRIVER Russian patent published in 2024 - IPC E02D7/06 

FIELD: construction; machine building.

SUBSTANCE: invention relates to hammers intended for driving piles on land and on water. Floating self-propelled pile driver contains basic floating conveyor, support frame, portal frame with carts, pile guides, pile driver, floats, hammers, hydraulic equipment. In the rear part of the conveyor there are posts with their lifting hydraulic cylinders, pivotally fixed to the support frame, on the other side to the posts there are telescopic booms with their lifting hydraulic cylinders. Telescopic booms are connected to a portal frame on which pile guides together with hammers and retractable outriggers are suspended. On the sides of the base conveyor there are floats arranged with the possibility of movement along the conveyor side and placement of backbone piles in them. Hammers are made with possibility of rotation relative to vertical axis of symmetry of pile guides at angle of 90°.

EFFECT: higher efficiency, expanded working zone of the pile driver, reduced labour intensity of positioning piles, increasing the stability of the pile driver, reducing the height of the pile driver for transportation.
