A mounting plate 14 is provided at the bottom of the driver's cab 12 near the fixing plate 13. A slot 19 is provided on the top of the mounting plate 14. Limiting slide rails 15 are provided at both ends of the driver's cab 12 near the fixing plate 13. The mounting plate 14 is welded to the bottom of the driver's cab 12 near the fixing plate 13. Limiting slide rails 15 are fixedly connected to both ends of the driver's cab 12 near the fixing plate 13. A protective device is provided in the slot of the fixing plate 13. The protective plate 16 has a limit plate 17 on its top and mounting blocks 18 on both ends of one side of the limit plate 17. The limit plate 17 is fixedly connected to the top of the protective plate 16. The mounting blocks 18 are fixedly connected to both ends of one side of the limit plate 17. The bottom of the protective plate 16 passes through the slot opened in the fixed plate 13 and is inserted into the slot 19. The two sides of the protective plate 16 are slidably connected to the inner walls of the two limit slide rails 15 respectively. Bolts 110 are provided in the threaded grooves opened in the two mounting blocks 18. The two sides of the driver's cab 12 are provided with protective doors 111. The bolts 110 pass through the threaded grooves opened in the mounting plate 14 and are threadedly connected to the top of the fixed plate 13. The two sides of the driver's cab 12 are movably installed with protective doors 111. The bottom of the vehicle body 11 on the side away from the mounting plate 14 is provided with a counterweight mechanism 2.

[0024] In this embodiment, when the driver is sitting in the cab 12 and driving the forklift to move goods, in order to ensure the safety of the cab 12, the driver can install the protective plate 16 in front of the cab 12 before starting the moving work. Specifically, the protective plate 16 is made of polycarbonate sheet, which provides a glass-like visual effect, while being lighter and stronger than traditional glass. The specific installation method involves inserting the protective plate 16 through a slot opened at the top of the fixing plate 13. During the continuous descent of the protective plate 16, its sides will... The guide rail 15 slides through the protective plate 16, ensuring that the protective plate 16 can be accurately inserted into the slot 19 during installation.

[0028] When the driver is in the cab 12 carrying out cargo handling operations, to ensure the safety of the cab 12, the driver can install the protective plate 16 in front of the cab 12 before starting the handling work. Specifically, one end of the protective plate 16 is inserted through the slot opened at the top of the fixing plate 13. During the continuous descent, both sides of the protective plate 16 will slide through the limiting slide rail 15. The design of the limiting slide rail 15 can ensure that the protective plate 16 can be accurately inserted into the slot 19 during installation. Therefore, the protective plate 16 will achieve the effect of positioning and installation. When the bottom of the limiting plate 17 contacts the top of the fixing plate 13, the mounting block 18 and the threaded groove opened in the fixing plate 13 will remain aligned. After the two are threadedly installed by the bolt 110, the protective plate 16 will be fixedly installed in front of the driver's line of sight in the cab 12. This design can prevent the cargo from directly hitting the driver in the cab 12, thereby avoiding serious personal injury.
