[0002] It is difficult and inefficient to transport precision and large equipment in buildings with two floors or above without elevators, or even impossible to transport, which greatly affects the work efficiency. Traditional equipment transportation methods are mostly carried, lifted, disassembled and transported by manpower, which is time-consuming and labor-intensive. While increasing construction costs, precision equipment may be damaged due to tilting, collision, etc. during the transportation process, and may even cause some safety accidents and the inability to transport heavy equipment. In order to solve the above problems, a high-rise building equipment lifting device is proposed. Summary of the invention

[0005] Furthermore, a traction rope is connected to the end lifting ear, and the traction rope is used to adjust the direction of the main beam.

[0006] Furthermore, it also includes: a hoist, a hoist is provided between the end lifting ear and the main hook, and the hoist is extended or shortened to adjust the center of gravity of the counterweight block of the main beam.

[0007] Furthermore, the weight of the counterweight block is greater than the weight of the equipment to be hoisted.

[0008] Furthermore, the main beam is made of H-shaped steel, and the mounting beam is made of channel steel.

[0009] The high-rise building equipment lifting device overcomes the limitations of low construction efficiency, serious equipment tilting and inability to move into place that are unavoidable in the traditional method of using manpower; the beneficial effects of the device are mainly in the following aspects: 1. The lifting is stable. Under the control of the traction rope, the equipment to be lifted can be safely and reliably lifted to the high-rise building through the balance of the counterweight block. With the help of a truck crane, equipment at different heights and positions can be lifted without damaging the floor, walls, equipment, etc.; 2. The device can select suitable specifications and models of lifting profiles and hand winches according to the weight of the lifted material. The profiles and hand winches are commonly used materials on the construction site, and there is no restriction on the material collection. The connecting plates are made on site and connected with the profiles and hand winches for use; 3.
