Abstract
The invention discloses a self-clamping fork arm carrier used for a small-tonnage electric forklift. An inner frame, a middle frame and an outer frame are combined and connected to from the fork arm carrier, and a buffer spring is arranged in the connection position. A fork is arranged on the outer frame, and a self-clamping pressing rod is arranged on a goods blocking frame connected with the outer frame. In the process that goods are carried through the forklift, the fork, the outer frame and the goods blocking frame are driven to fall as a whole through the self-weight of the goods. The self-clamping function of the self-clamping pressing rod is achieved through a compression spring connected to the rear end of the self-clamping pressing rod according to the lever principle. Seen from the feedback of the actual use condition, the self-clamping fork arm carrier is more reasonable and better in actual running effect, and it is better ensured that the reliability of the whole forklift is improved.
