[0019] Referring to Figures 1-3, the plate lifting device includes a crossbeam 1, a longitudinal beam 2 is provided below the crossbeam 1, and a sleeve 3 is fixedly connected to the top of the longitudinal beam 2. Through the sleeve 3, the two longitudinal beams 2 can move closer or further apart along the two sides of the crossbeam 1.

[0020] A sling sleeve 4 is slidably connected to the longitudinal beam 2, and a sling 5 is provided below the longitudinal beam 2. By moving the two sling sleeves 4 closer or further apart on the longitudinal beam 2, the two slings 5 ​​can move closer or further apart, thereby allowing adjustment according to the size of the board.

[0021] A hook 6 is provided below the sling 5, and a placement plate 7 is fixedly connected below the hook 6. The board is placed on the placement plate 7, which makes it easy for the sling 5 and the hook 6 to lift the board.

[0022] The crossarm 1 and the sleeve 3 are provided with first pin holes 8. The first pin holes 8 on the crossarm 1 and the first pin holes 8 on the sleeve 3 are corresponding. A first indexing pin 10 is installed in the first pin holes 8. According to the length of the plate, the sleeves 3 are brought closer to each other along the crossarm 1 until the plate 7 is placed on both sides of the plate. Then, the first indexing pin 10 is inserted into the first pin holes 8 to fix the relative position of the crossarm 1 and the sleeve 3.

[0023] The longitudinal support 2 and the sling sleeve 4 are provided with second pin holes 9. The second pin holes 9 on the longitudinal support 2 correspond to the second pin holes 9 on the sling sleeve 4. A second indexing pin 11 is installed in the second pin holes 9. A rectangular plate 20 is fixedly connected to the top of the placement plate 7. According to the width of the plate, the sling sleeves 4 are moved closer to each other along the longitudinal support 2. The sling sleeves 4 drive the slings 5 ​​to move closer to each other until the rectangular plate 20 on the placement plate 7 clamps and fixes the two sides of the plate. Then, the second indexing pin 11 is inserted into the second pin hole 9 to fix the relative position of the longitudinal support 2 and the sling sleeve 4.

[0024] A first lifting ring 12 is provided below the sling slide 4. A first fixing hole is provided on the sling slide 4 and the first lifting ring 12. A first fixing pin 13 is installed in the first fixing hole. One end of the sling 5 is sleeved on the first lifting ring 12. The first fixing pin 13 is inserted into the first fixing hole to fix the first lifting ring 12 to the bottom of the sling slide 4, so that the sling slide 4 can drive the sling 5 on the first lifting ring 12 to rise or fall.

[0025] A connecting plate 14 is provided above the hook 6. Circular holes are provided on the hook 6 and the connecting plate 14, and fixing bolts 15 are installed in the circular holes. A second lifting ring 16 is provided below the sling 5.
