Description of Lock Nut Hydraulic Cylinder Jack
It is designed with a safety pressure maintaining device and a
built-in pressure relief valve to prevent overload, so as to
protect the jack for safe operation. And design four sets of stop
valves, which can control the synchronous lifting and lowering of
the jack at any time.
The connection of the device is connected by a high-pressure rubber
hose and threaded joints, which are quick to use and overcomes the
fast tradition. The shortcoming of joint oil leakage is mainly used
in electric power, construction, machinery manufacturing, mining,
railway bridges, shipbuilding, and other industries for equipment
installation, jacking, and dismantling operations.

Features of Lock Nut Hydraulic Cylinder Jack
The jacking method can avoid high-altitude operations and is convenient for construction, but the jacking technology requires high requirements. A construction method in which the roof structure is assembled or poured on the ground and is gradually lifted to the design level by using jacks and alternately filled columns. This method does not require large-scale lifting equipment, and the entire roof that has been constructed on the ground, including roof waterproofing, paint, and pipelines, can be lifted into place at one time. The lightweight and compact design is suitable for narrow working spaces, and the piston automatically returns oil to the chrome-plated surface of the piston to prolong its life of the piston.
There are two kinds of Lock Nut Hydraulic Cylinder Jack
① The lifting method jack is supported upside down on the pad under
the fulcrum of the roof structure, and the pad is the future column
cap. In the beginning, the column cap is supported on both sides of
the column base block. With the oil inlet and return of the jack,
the temporary pad is filled in and the formal column block is
replaced, and the column cap will gradually raise the roof
structure. The column block is square and door-shaped (see the
figure [schematic diagram of the lifting process of the upper
jacking method and the column block diagram]). During the
installation of the column block, it is advisable to lay cement
mortar and welded sidebars in time, and seal the opening of the
column block to enhance the stability of the column. In the upward
jacking method, the lifting weight of the jack is constant and the
stability is better, so it is widely used at present. Since it is a
high-altitude operation, measures should be taken during the
jacking process to prevent the roof structure from shifting, and
attention should be paid to the synchronization of jacking.
② Lower jacking method. The jack is always placed on the column
base, and the column blocks are filled with the top, which can
reduce high-altitude operations, but the jacking weight gradually
increases, especially when the movable fulcrum is formed at the
column base, the stability is poor, and it has been seldom used.
