An eyelet is rigidly attached to the boom from below, which is connected to the body of the additional hydraulic cylinder by means of a cylindrical rotation hinge. The fork gripper in the upper part is connected to the handle and to one end of the first rocker arm by means of a cylindrical rotation hinge, and in the lower part of the fork gripper, the eyelet is connected to the second end of the first rocker arm and to one side of the connecting rod by means of a cylindrical rotation hinge. The additional hydraulic cylinder is connected by a rod to the other side of the connecting rod and to one end of the second rocker arm using a cylindrical rotation hinge, and the other end of the second rocker arm is attached pivotally to the boom and to the handle. The handle, connecting rod and two rocker arms in the assembly represent the form of a parallelogram mechanism.
