What are the classifications of tank hydraulic jacking system?

The tank hydraulic jacking system is mainly used for vertical tank top to tank bottom construction, and can also be used for jacking or lifting of large work pieces. It is a closed or meshed hoist way enclosed by a building or light steel structure and uses a hydraulic drive to drive the top of the cylinder.

 

Here is the content list:

l Tank hydraulic jacking system classified according to structural characteristics standards.

l The tank hydraulic jacking system is classified according to the standard of the tower structure rotation mode.

 

The tank hydraulic jacking system is classified according to the standard of walking mechanism.

It can be divided into mobile tank hydraulic jacking system and fixed tank hydraulic jacking system.The mobile tank hydraulic jacking system can run on a special track, has good stability, can walk with load, and has high work efficiency, so it is widely used in construction and installation projects.

 

The fixed tank hydraulic jacking system is divided into two types: attached jack-up type and inner-climbing type according to the different installation positions. The attached jack-up tower crane can rise as the building rises and is suitable for high-rise buildings.

 

Tank hydraulic jacking system classified according to structural characteristics standards.

It can be divided into pitch luffing tank hydraulic jacking system and trolley luffing tank hydraulic jacking system.The tank hydraulic jacking system of the pitch luffing jib tower does not achieve luffing by lifting and lowering the boom. Its advantages are: it can give full play to the effective height of the boom, the mechanism is simple, and the disadvantage is that the minimum amplitude is limited to the maximum amplitude About 30%, it cannot be completely close to the tower body, and the load rises and falls with the boom during luffing, and the luffing with load is not allowed.

 

The trolley luffing boom tower tank hydraulic jacking system relies on the trolley installed on the horizontal boom track to achieve luffing. Its advantages are: a large luffing range, the load trolley can approach the tower body, and it can change with load. The disadvantages are that the force of the boom is complex, the structure requirements are high, and the boom and the trolley must be on the upper part of the building, and the installation height of the spire is 15-20 meters higher than the roof of the building.

 

 

The tank hydraulic jacking system is classified according to the standard of the tower structure rotation mode.

It can be divided into down-turn tank hydraulic jacking system and up-turn tank hydraulic jacking system.The tank hydraulic jacking system of the lower slewing tower crane is equipped with the slewing support and the main mechanism of the balance weight at the lower end. Its advantages are: less bending moments on the tower, low center of gravity, good stability, convenient installation and maintenance, but the disadvantages are correct The slewing bearing has high requirements and the installation height is limited.

 

The upper slewing tower tank hydraulic jacking system has the slewing support, balance weight, and main mechanisms at the upper end. Its advantage is that since the tower body does not rotate, the lower structure of the tower body can be simplified and the jacking and joints are convenient.

 

The disadvantage is that when the building exceeds the height of the tower, the rotation of the tower crane is restricted due to the influence of the balance arm. At the same time, the center of gravity is higher, the wind pressure increases, and the weight increases, which increases the total weight of the whole machine.
