The bottom of the top frame 3 is fixed with a main frame 1, an inner hanging frame 2, and a traveling mechanism that can travel along the top of the tank wall panel 17. The traveling mechanism is located between the main frame 1 and the inner hanging frame 2. The main frame 1 includes a fixed section 4 and several extension sections 5. The upper end of the fixed section 4 is connected to the top frame 3, and several extension sections 5 are sequentially spliced ​​to the lower end of the fixed section 4. In this embodiment, the wall-mounted trolley has the capability of a construction operation platform. Through the walking mechanism, it drives the top frame 3 and the main frame 1 and inner hanging frame 2 fixed on it to move along the tank wall 17, which facilitates tank assembly, welding, corrosion protection and inspection construction. It avoids the phenomenon of roller 7 getting stuck due to the erection of scaffolding outside the tank and the displacement of the hand-pushed frame, thereby improving the safety of operation and speeding up the construction progress. At the same time, the main frame 1 is made up of fixed section 4 and several extension sections 5. The height of the main frame 1 can be adjusted by increasing or decreasing the number of extension sections 5 to meet the needs of tanks of different heights. Moreover, the modular splicing method makes the installation process simpler, reduces the amount of on-site welding or cutting work, and reduces installation costs and time.

[0026] In some embodiments, the lower end of the fixed segment 4 is detachably connected to the uppermost extension segment 5 and adjacent extension segments 5 via connectors.

The rollers 7 are 200H type rollers, the support connecting plate 9 is made of 10mm thick steel plate, the first guide wheel 10, the second guide wheel 11 and the third guide wheel 12 are 120 type rubber wheels, and the drive motor 8 is a three-phase asynchronous motor with remote control function and a power of 2.2kW. It is equipped with an SM-A600 wireless remote controller for remote control.

[0038] During the construction of the external floating roof tank, a 50T crawler crane is used to place a wall-mounted trolley of a length corresponding to the height of the tank wall on the top of the tank wall panel 17. The operators control the rollers 7 to move on the top of the tank wall panel 17 via a wireless remote control driven by the drive motor 8. The operation can be carried out inside and outside the tank by relying on the wall-mounted trolley, which improves the safety of the operation and speeds up the construction progress.
