[0002] With the development of prefabricated buildings in China, the application of large flat-top tower cranes is becoming increasingly widespread; the flat-top tower crane realizes the transportation of goods through the frequent reciprocating movements of the hoisting mechanism, luffing mechanism, and slewing mechanism. The daily maintenance of these three mechanisms has become a top priority. There is enough space around the hoisting mechanism and slewing mechanism to allow workers to perform maintenance. However, due to the lightweight design of the boom, the space around the luffing mechanism cannot meet the needs of workers for maintenance, so it is necessary to add a luffing maintenance platform to the luffing mechanism.

[0003] At present, in order to ensure the force, the existing luffing maintenance platforms for tower cranes mostly use large profiles to connect with the boom structure, resulting in an overweight load on the boom; at the same time, the overall structure is complex and heavy, the disassembly and assembly are cumbersome, and the safety performance is poor.

[0032] Specifically, the platform chassis 1 is an integrally formed metal plate. The metal plate has the characteristics of light weight, high strength, and strong plasticity, making the overall luffing maintenance platform lighter in weight, thereby reducing the load on the boom 6;

[0033] In this embodiment, the first direction is the vertical direction;

[0034] Working principle: When maintenance is required for the luffing mechanism 7 of the tower crane, the first connection component is connected to the boom 6. At this time, the staff stands on the luffing maintenance platform to perform maintenance on the luffing mechanism 7. Compared with the prior art, using larger profiles to connect with the boom 6 structure results in an overweight load on the boom 6; in the present application, the platform chassis 1 uses a metal plate, which is lighter in weight while ensuring good strength and stiffness, thereby reducing the load on the boom 6 and having strong safety performance; at the same time, the entire platform only includes the platform chassis 1, the protection component, and the first connection component, with a simple overall structure and convenient disassembly and assembly.
