Description of hydraulic strand jack system|heavy lifting
The hydraulic strand jack is compact in structure and can lift and lift heavy objects smoothly. The lifting weight has reached 750 tons, and the transmission efficiency is high, so it is widely used; but it is easy to leak oil and should not support heavy objects for a long time.
hydraulic strand jack generally use a needle cylinder, which is filled with water and is used to hold the outlet by hand. You have to use a lot of force to push the water out, because the pressure on both sides is the same, but the pressure is different. The pressure is the pressure and the area, the pressure is certain, and the larger the area is, the higher the pressure is. Therefore, the steel column area of the top of the hydraulic jack is much larger than the small steel column that you press by hand. The two steel columns have pistons. The liquid inside is generally lubricating oil, that is to say, the pressure of the two steel columns is the same when the size of the large steel column is large, so the large steel column is affected by the pressure when the pressure is equal. The force is N times that of a small steel column.
hydraulic strand jack: Hydraulic pump driven by manpower or electric power, driven by hydraulic system, using cylinder or piston as the lifting member.hydraulic strand jack can be divided into integral and separate. The integral pump is integrated with the hydraulic cylinder; the separate pump is separated from the hydraulic cylinder and the middle is connected by a high pressure hose.
