[0041] The embodiment specifically:

[0042] A φ50mm, 6000mm long steel pipe is used as the main balance beam 1, and the distance to the ground is 2000mm; the power is reduced by increasing the length of the power arm 4 of the main balance beam 1, and the direction and speed of transportation are changed by the rubber hub. At 1500mm of the main beam, two 30° right-angled triangles are welded with a φ50mm, 1750mm long steel pipe to form the support frame of the main balance beam 1. The two right-angled sides are welded with the main balance beam 1, and the 30° right-angled side is extended to a horizontal position beyond the main balance beam 1500mm, and then a φ50mm steel pipe is used as a diagonal bracing 9 to be welded and reinforced to make it firm and reliable, not bent or deformed, forming a strong support as a fulcrum. A φ800mm circular lifting tray 6 device is connected and installed at the top of the φ50mm, 1750mm long steel pipe with a clip, and the lifting tray is equipped with fixed guide wheels at four direction points, supporting the lifting wire rope 3. The highest distance from the lifting tray to the ground can reach 3000mm. The lifting wire rope 3 is connected with the bidirectional self-locking winch 7 (portable winch) on the column leg 2 to form a movable lifting device that can be used for multiple purposes. The 90° angle is the fulcrum of the main balance beam 1 welded with the column leg 2, and the column leg 2 is connected with the running rubber hub below to transfer the bearing capacity of the fulcrum to the rubber hub and change the direction of movement through the rubber hub. The resistance arm 5 (1500mm long) of the main beam is from the 90° angle fulcrum to the top of the circular lifting tray 6, and the rubber hub below the column leg 2 is the fulcrum of the main balance beam 1. The operating control handle from the 90° angle fulcrum to the tail of the main balance beam 1 is the power arm 4 (4500mm long) of the main balance beam 1. A φ20mm round steel is welded on the main beam to serve as an auxiliary stay to prevent the main balance beam 1 from bending and deforming. When lifting long materials, the hook 8 should be securely hooked, and after the long materials are lifted and balanced, the movement begins.

[0043] Working principle: According to the balance condition of the lever: power x power arm 4 = resistance x resistance arm 5, formula:

[0044] F1xL1 = F2xL2, variant: F1:F2 = L2:L1, the power arm 4 is three times the resistance arm 5, so the power is one third of the resistance. The length ratio of the lever, i.e. increasing the length of the power lever arm; the larger the ratio of the length of the lever arm, the smaller the required force, and the greater the work that can be done. When lifting heavy objects, use the hook 8 to hook the long materials or equipment (materials), press down the power arm 4, and since the length ratio of the lever is 1:3, only 1 / 3 of the force is needed to easily lift the heavy object, and the direction or speed of movement is changed through the rubber hub.
