Detailed Description

The fork carrier of a manual fork truck as shown in fig. 1 and 2 comprises two auxiliary forks 1 and a plurality of extension rods 2, wherein the extension rods 2 are arranged on the outer sides of the two forks 3 and on two sides of a fork end connecting frame 4, the two auxiliary forks 1 are respectively arranged on the extension rods 2 on two sides and are arranged in parallel with the two forks 3, and a locking mechanism is arranged between the auxiliary forks 1 and the extension rods 2.

As the preferential design, one side of auxiliary fork 1 sets up articulated pole, and the articulated pole other end sets up gyro wheel 5, and the height between gyro wheel 5 bottom surfaces to auxiliary fork 1 up end equals the height between fork pulley bottom surfaces to the fork up end.

The manual fork truck has a lifting process, the auxiliary fork is lifted in a process that the fork is gradually lifted from low to high, and after the tray is completely lifted by the baffle, the hinging rod is pulled to be perpendicular to the auxiliary fork surface from being parallel to the auxiliary fork surface, so that the support to the bottom surface is formed. Further satisfies the requirement of stability, also can increase the supporting strength of vice fork face.
