Specific implementation mode
The attached drawing of content combination below elaborates to the specific implementation mode of the present invention.
A kind of no top beam hydraulic rack, including hydraulic lifting main body 1 and fixing bracket main body 2, the hydraulic lifting main body 1
It is fixed on 2 left end of fixing bracket main body, 2 right end of fixing bracket main body is equipped with hydraulic lifting and controls main body 3, the fixed branch
2 left side of frame body is equipped with drawing connecting shaft 4.
1 downside of the hydraulic lifting main body is equipped with piston shoes 5, and 1 middle part of the hydraulic lifting main body is equipped with hydraulic lifting storehouse 6,
6 outside of the hydraulic lifting storehouse is equipped with upright fixed frame 7, and the upright fixing bracket 7 is connect with lifting buckle 8, the hydraulic pressure
6 right side of lifting storehouse is respectively equipped with hydraulic circulation inlet 9 and hydraulic circulation liquid outlet 10, and the hydraulic lifting storehouse 6 is lifted with hydraulic pressure
