[0029] Since this mobile tower crane includes a tower crane box 2, a tray loading mechanism 3, a chassis frame 1, and a moving component 4, the tray loading mechanism 3 is connected to one side of the tower crane box 2 and is located in different vertical space positions from the tower crane box 2, the tower crane box 2 is installed on the chassis frame 1, and the moving component 4 is arranged on the ground-facing side of the chassis frame 1 and is used to drive the tower crane box 2 to move, the tray loading mechanism 3 has a more sufficient loading space compared to the tray mechanism hidden in the tower crane box 2, which can improve the bearing capacity of the mobile tower crane. At the same time, the independent tray loading mechanism 3 also makes the operation of picking up and placing objects not restricted by the structure of the tower crane box 2, and the picking up and placing actions are more convenient and free. In addition, the moving component 4 is arranged on the ground-facing side of the chassis frame 1 to drive the tower crane box 2 to move, which is convenient for moving the whole mobile tower crane and improves the user experience.

[0030] Furthermore, the moving component 4 includes four rotating wheels 41; the four rotating wheels 41 are distributed on the ground-facing side of the chassis frame 1 to stably support the chassis frame 1; at least one of the four rotating wheels 41 is a foot brake wheel. Specifically, in this embodiment, the chassis frame 1 is rectangular, and the four rotating wheels 41 are respectively arranged at the four corner positions on the bottom side of the chassis frame 1. The four rotating wheels 41 can all be universal wheels, and each universal wheel is a foot brake wheel. In this way, the force on the chassis frame 1 can be ensured to be uniform, the movement is stable, and it is convenient to brake and stop. In some embodiments, the shape of the chassis frame 1 can be set as a trapezoid, pentagon, hexagon, waist shape, etc. In some embodiments, the number of rotating wheels 41 of the moving component 4 can be set as five, six, etc. In some embodiments, the moving component 4 can also include a driving wheel, that is, a part of the rotating wheels 41 has power, such as a motor for driving its rotation is provided inside the rotating wheel 41. Among them, the switch control of the motor can be set outside the tower crane box 2 or as an additional remote control. By controlling the switch action of the motor, the driving of the moving component 4 can be realized, which is more labor-saving.

[0031] Furthermore, the chassis frame 1 may include an upper plate body 10 and a lower plate body 11; a suspension tower box 2 is installed on the upper plate body 10, and a moving component 4 is arranged on the lower plate body 11.

Four rotating wheels 41 are respectively fixed at the four corner positions of the lower plate body 11. It should be understood that the specific structure of the chassis frame 1 can be adaptively adjusted according to the actual situation as long as it can carry the suspension tower box 2 and install the moving component 4.

[0032] Furthermore, the tray loading mechanism 3 is located in the vertical space above the chassis frame 1, and the suspension tower box 2 is located in the vertical space above the chassis frame 1. Specifically, the suspension tower box 2 is arranged at a position close to one side above the chassis frame 1, while the tray loading mechanism 3 is located at a position close to the middle above the chassis frame 1. In this way, when the tray loading mechanism 3 carries heavy objects, the center is located at the middle position above the chassis frame 1, which is more stable and not prone to tipping over.

[0033] Furthermore, the tray loading mechanism 3 includes a first tray 31 and a second tray 32 that are assembled in parallel at intervals on one side of the suspension tower box 2. Both the first tray 31 and the second tray 32 include a sheet metal bearing plate 301 and reinforcing ribs 302. Each edge of the sheet metal bearing plate 301 is bent downward to form a reinforcing structure 303, and the reinforcing ribs 302 are fixed to the bottom side of the sheet metal bearing plate 301. The tray structure set in this way has higher strength and stronger load-bearing capacity. It should be understood that the tray loading mechanism 3 may not be limited to including the first tray 31 and the second tray 32, and may also include a third tray, a fourth tray, a fifth tray, etc. Each tray is arranged at intervals, so that the load-bearing capacity of the tray loading mechanism 3 can be further improved.

[0034] Furthermore, a vertically extending installation groove 21 is provided on the outer wall of the suspension tower box 2, and an installation block 22 is slidably assembled in the installation groove 21, and the installation block 22 and the installation groove 21 cannot be separated; the tray loading mechanism 3 further includes a connecting member 35, and the connecting member 35 has two connecting pieces perpendicular to each other and a reinforcing rib connecting the two connecting pieces; both the first tray 31 and the second tray 32 are assembled to the suspension tower box 2 through the connecting member 35.

[0035] Specifically, two vertically extending mounting grooves 21 are provided on one side of the outer wall of the tower box 2. The two mounting grooves 21 are respectively close to the edges of one side of the outer wall. The mounting groove 21 is a T-shaped groove or a dovetail groove. Correspondingly, the cross-section of the mounting block 22 is T-shaped or dovetail-shaped. In this way, the mounting block 22 can be slidably connected in the mounting groove 21 without disengaging from the opening of the mounting groove 21. Screw holes are provided at the positions corresponding to the openings of the mounting block 22 and the mounting groove 21. Both the first tray 31 and the second tray 32 include two reinforcing ribs 302. The reinforcing ribs 302 are L-shaped.

[0036] Further, an elastic sheet 221 is provided inside the mounting block 22. The elastic sheet 221 abuts against the groove wall of the mounting groove 21 away from its opening. Through the arrangement of the elastic sheet 221, one side of the mounting block 22 can always abut against one side of the mounting groove 21, preventing the mounting block 22 from sliding randomly, making it easier to move the mounting block 22 to a specific position, thus facilitating the installation between the tray and the mounting block 22.

[0037] In some embodiments, a friction sheet can be provided on the side of the connecting piece 35 close to the tower box 2, so as to increase the friction force and improve the connection stability between the tray and the tower box 2. In some embodiments, card holes spaced in the vertical direction can be provided in the mounting groove 21. The mobile tower can also include a retaining pin. When the tray is fixed, the retaining pin can be inserted into the card hole below the corresponding mounting block 22. The retaining pin is used to block the mounting block 22 from sliding downward. In this way, the reliability of the tray load bearing can be further improved, and accidental sliding can be avoided.
