The openings of the tape carrier fork ways 20 of all the carrier units 11 face in the same direction, for example, the openings of all the tape carrier fork ways 20 face to the left. Thus, between two adjacent sets of load-bearing units 11, at the top of the underframe 1, the fork tines of the forklift are inserted into the rack fork-taking passage 21 for separating and forking the stacked goods from the whole smart fixed rack (or forking the goods borne by the fork tines on the load-bearing units 11) is formed by the arrangement distance of the two sets of load-bearing units 11 along the operation depth direction of the forklift in the goods stacking space, that is, the goods are stacked on the plane formed by the load-bearing units 11, so that a passage for enabling the forklift to fork the goods independently is formed between the suspended part of the goods between the adjacent load-bearing units 11 and the top surface of the underframe 1.

Because the transverse wide end face of the bearing unit 11 is of an inverted L-shaped structure, the adjacent fork taking channel 21 and the fork taking channel 20 with a rack are matched through structures, so that the insertion of the fork of the forklift is facilitated, and the switching of the fork in the fork taking channel with the rack and the fork taking channel with the rack is facilitated, for example: after stacked goods which are forked by the forklift are placed in the goods stacking space through the rack-releasing and forking channel 21, the fork teeth do not need to be withdrawn, and the fork teeth are translated into the rack-carrying and forking channel 20, so that the fork of the rack and the loaded goods can be skillfully and fixedly forked.

In the above structure of the carrying unit 11, in order to ensure that the fork of the forklift stably applies force and prevents slipping in the rack forking channel 20, the support members 22 constituting the carrying unit 11 may be suspended at the bottom of the cross beam to form an upward arc-shaped arch structure, and the arc-shaped arch structure is arranged between the legs and the outer end of the suspended cross beam and near one side of the legs.

Among the plurality of sets of load carrying units 11 arranged on the top of the underframe 1, the outermost load carrying unit 11 on the right side in the forklift operation depth direction of the cargo stacking space is substantially flush with the right side edge vertical surface of the underframe 1, that is, the support members 22 of the outermost load carrying unit 11 are arranged flush with the right side edge vertical surface of the underframe 1.

Among the multiple groups of bearing units 11 arranged on the top of the underframe 1, the bearing unit 11 on the outermost side on the left side is matched with the vertical face of the left edge of the underframe 1 in a staggered arrangement structure along the operation depth direction of the forklift in the goods stacking space, and in the staggered arrangement structure matching, the bearing unit 11 on the outermost side is positioned on the inner side of the vertical face of the left edge of the underframe 1.

In the matching of the staggered arrangement structure, the top surface of the bottom frame 1 at the outer side of the outermost bearing unit 11 at the left side is connected with a left side support 14, the left side support 14 mainly comprises a longitudinal beam and a support leg, the support leg is connected at the left side edge of the bottom frame 1 and is basically flush with the vertical surface of the left side edge of the bottom frame 1, and the longitudinal beam is basically flush with the bearing surface 12 of the bearing unit 11 and is arranged along the depth of the front side and the rear side of the bottom frame 1. In this way, the left side bracket 14 is substantially flush with the left side edge elevation of the chassis 1, and the left side bracket 14 and the adjacent left outermost load-bearing unit 11 form a racking fork channel 21 therebetween.

Thus, each group of bearing units 11 on the top of the underframe 1 is combined with the left side bracket 14, and the left and right sides in the forklift operation depth direction of the goods stacking space jointly form a goods effective bearing plane which is basically equal to the top surface of the underframe 1 and can basically and completely cover the top surface of the underframe 1 from the upper position.
