[0002] A lifting platform is a lifting machine that transports people or objects vertically. It also refers to equipment for vertical transportation in logistics systems such as factories and automatic warehouses. The lifting platform is often equipped with various flat conveying equipment as a connecting device for conveyor lines at different heights. It is generally driven by hydraulics, so it is called a hydraulic lifting platform. In addition to being used for transporting goods at different heights, it is widely used in high-altitude installation, maintenance and other operations.

[0003] Since the lifting platform is used for high-altitude operations, its stability after lifting is extremely important. The current method of testing its stability is to raise the lifting platform and then pull the table horizontally with ropes to test its maximum lateral bearing capacity. Currently, the ropes are mostly tied to the protective railings of the table, and the railings are generally made of thinner metal rods that can withstand less force, causing damage to the railings during the pulling process.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-2 As shown, a pulling tool for testing the stability of a lifting platform comprises two support sleeves 2 connected by a pin shaft 3. When in use, the two support sleeves 2 are vertical. When not in use, the two support sleeves 2 are overlapped for storage. A pull rod 1 is inserted at both ends of the support sleeve 2. A locking bolt 201 for fixing the pull rod 1 is provided on the side wall of the support sleeve 2. The length of the pull rod 1 is adjusted according to the size of the lifting platform, and is fixed by the locking bolt 201; Figure 4 As shown, the end of the pull rod 1 is provided with a clamping rod 103 that cooperates with the outer side wall of the lifting platform. The clamping rod 103 is clamped on the outer side of the lifting platform. The outer side wall of the clamping rod 103 is provided with a pull ring 102 for rope binding.
