Abstract

The utility model provides a forklift truck crane boom attachment. The forklift truck crane boom attachment comprises a front arm beam. One end of the front arm beam is clamped on a beam of a fork arm carrier of a forklift truck through a connecting plate, and the other end of the front arm beam is connected with hook assemblies. The forklift truck has many different kinds of functions as different attachments are arranged. By arranging the special attachment of a crane boom on a forklift truck, the requirements of a lifting scene with a small tonnage can be satisfied, and a certain maneuverability is achieved. The crane boom attachment is clamped on the beam of the fork arm carrier through hooks on the connecting plate and is transversely limited by embedding a stop block into a groove of an upper beam. A client can select hanging point circular holes at different positions to install the hook assemblies according to actual working conditions so that goods with different weights and sizes can be borne. The hook assemblies are respectively composed of detachable parts, so that the hook assemblies are convenient to maintain. The front arm beam is formed by welding an upper seal plate, side plates, a lower seal plate and rib plates.
