[0022] In this embodiment, by installing the load beam 3 inside the chassis 1 and the rollers 10 inside the sliding grooves 12, the chassis 1 can be moved by the load beam 3 when the first motor 8 is started. By sleeving the first pulley 11, the second pulley 4, and the third pulley 13 with the steel cable 19, a labor-saving pulley block can be formed to lift the goods. By installing the first pulley 11 and the second pulley 4 inside the fixing plate 2, the fixing plate 2 and the hook 7 can be lifted upward to lift the goods when the steel cable 19 is tightened. By installing two rivets 5 inside the fixing block 6 in a linear array, the fixing block 6 can be fixed more firmly inside the fixing plate 2. By fixedly connecting one end of the steel cable 19 to the outer surface of the fixing rod 14, the steel cable 19 can be prevented from falling off when using the pulley block. By opening two sliding grooves 12 inside the load beam 3 and making the shape of the load beam 3 be in an I shape, the load-bearing capacity of the load beam 3 can be increased. By installing four side supports 21 on both sides of the support column 20 in two groups, the fixing can be made more stable when fixing the crane.

[0023] Specifically, the load beam 3 is located inside the chassis 1, and the rollers 10 are located inside the sliding grooves 12. By installing the load beam 3 inside the chassis 1 and the rollers 10 inside the sliding grooves 12, the chassis 1 can be moved by the load beam 3 when the first motor 8 is started.

[0024] Specifically, the first pulley 11, the second pulley 4, and the third pulley 13 are sleeved with the steel cable 19. By sleeving the first pulley 11, the second pulley 4, and the third pulley 13 with the steel cable 19, a labor-saving pulley block can be formed to lift the goods.

[0028] Specifically, two sliding grooves 12 are opened inside the load beam 3, and the shape of the load beam 3 is in an I shape. By opening two sliding grooves 12 inside the load beam 3 and making the shape of the load beam 3 be in an I shape, the load-bearing capacity of the load beam 3 can be increased.

[0029] Specifically, there are four side supports 21, which are divided into two groups and installed on both sides of the support column 20. By the four side supports 21 divided into two groups and installed on both sides of the support column 20, the fixing can be made more stable when fixing the crane.

[0030] The working principle or usage process of the present utility model: When the present utility model is in use, first hook the goods with the hook 7, then start the second motor 16 to rotate the second rolling shaft 17 to rotate the wire winding drum 18 to wind up the steel cable 19. The tightening of the steel cable 19 will rotate the first pulley 11, the second pulley 4, and the third pulley 13 to lift the fixing plate 2 to lift the goods. Then turn on the first motor 8 to rotate the first rolling shaft 9 to rotate the pulley 10, and the pulley 10 slides through the chute 12 opened on the load-bearing beam 3 to move the goods to a suitable position. Then reverse-rotate the second motor 16 to rotate the second rotating shaft 17 to rotate the wire winding drum 18 to release the steel cable 19 to lower the fixing plate 2 to lower the goods. Among them, the electrical equipment in this device is externally connected to a power source and is controlled to operate and shut down through a supporting control switch.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
