ANCHORAGE DRUM FOR VEHICLE SELF-RECOVERY Russian patent published in 2023 - IPC B66D1/14 

FIELD: transport engineering.

SUBSTANCE: invention relates to the field of transport engineering. The anchorage drum refers to the means for a stuck vehicle’s self-recovery when there are no objects to which the cable can be hooked. It contains a housing made of rigid structural material in the form of a hollow closed cylindrical container. The housing is equipped with hatches for loading ballast. Several rings equipped with locking screws for fixing are put on the body with a gap providing axial and radial movement. On the side surfaces of each ring, axes and stops for bayonet hooks are rigidly attached along the circumference. Bayonet hooks with the possibility of rotation are put on the axis. They include handles with support recesses and bayonet blades with an advance in the upper part. Part of the bayonet hooks are immersed in the ground. The winch is turned on to tighten the cable. Due to the occurrence of torque, the housing rotates relative to its axis. The stops are thrust into the supporting recesses of the bayonet hook handles and immerse the bayonet blades in the ground.

EFFECT: ensuring a continuous process of self-recovery without stopping.
