The first longitudinal beam 12 on the corresponding side is provided with a bolt hole 13 for inserting the bolt body 51. When the carrier 1 is turned over to the state as shown in fig. 1, the carrier 1 can be locked by inserting the bolt body 51 into the bolt hole 13, so as to provide safety and convenience for the operator to perform corresponding maintenance operation. Furthermore, the safety bolt assembly 5 is arranged on the second longitudinal beam 22, which is helpful for an operator to operate the safety bolt assembly 5 more conveniently when rotating the hand wheel 4.

In some embodiments, only one safety bolt assembly 5 may be provided; and a plurality of them may be provided for higher reliability. For example: as shown in fig. 1, two safety bar assemblies 5 are provided, which two safety bar assemblies 5 each lock two first longitudinal beams 12. Similarly, only one or two bolt holes 13 may be provided for the same safety bolt assembly 5. When two bolt holes 13 are provided for the same safety bolt assembly 5, the safety bolt assembly 5 is adapted to one of the two bolt holes 13 when the carrier 1 is turned to the front and to the back.

In the safety bolt assembly 5 described above, the bolt body 51 is generally cylindrical, as shown in figure 2. "substantially" herein means: the portion of the plug body 51 extending in the direction of the axis X shown in fig. 2 is formed by one or more sections of a cylinder so that the plug body 51 can rotate circumferentially without also excluding a notch or a groove around its axis. The bolt 51 has a rear end 511, the rear end 511 is located at an end of the bolt 51 away from the carrier 1, and the front end of the bolt 51 is opposite to the rear end 511.
