Simple Hydraulic Jacks for Vertical Tank Construction

I.Introduction of simple jack

 Simple unfixing Holding -latch hydraulic Jack is a double acting hydraulic jack (also known as hydraulic lifting machine) with upper and lower clamping heads divided into two bodies. It is suitable for lifting construction of various large storage tanks (steel) or other heavy objects.It needs to cooperate with the lifting rod to achieve reciprocating lifting work.

II. Structure description of simple jack

 The jack comprises an oil cylinder and a piston, the upper and lower ends of the oil cylinder are respectively provided with an upper cylinder head and a lower cylinder head, and the upper cylinder head and the lower cylinder head are respectively provided with an oil inlet and outlet hole;The piston is arranged in the middle of the piston rod, the both ends of the piston rod respectively extend out of the upper cylinder head and the lower cylinder head, the piston rod is hollow, and the lifting rod axial through the piston rod, the lifting rod on the upper side and the lower side of the piston rod are respectively provided with a locking device;The locking device comprises a gripping part set on the lifting rod, the gripping part is provided with a large and small conical hole, the inner side of the conical hole is circumferentially provided with a number of wedge blocks;The outer surface of the wedge block is compatible with the conical hole, the inner side of the wedge block is provided with a clamping tooth, the clamping tooth is held on the lifting rod, the wedge block is provided with a circular spring chuck;The spring chuck is provided with a plurality of round holes, a round hole is provided with a reset spring, the upper side of the spring chuck is provided with an annular cover fixed with the grip part, and the both ends of the reset spring are respectively conflicted between the lower end face of the wedge block and the cover;The grip part on the upper side of the locking device is relatively fixed with the upper end of the piston rod, and the grip part on the lower side of the locking device is relatively fixed with the lower cylinder head by the support.

III.Features of simple jack

1,Simple jack adopts low relaxation steel strand, as long as there is a reasonable bearing lifting point, lifting height is not restricted;

2,Through the expansion and combination of simple jacks, the lifting weight, span and area are unlimited;

3,Small volume, light weight, large bearing capacity, convenient and flexible installation, especially suitable for small space or indoor large tonnage tank lifting;

4,The simple jack has reverse motion self-locking, which makes the lifting process very convenient, and the storage tank can be locked reliably at any position in the lifting process for a long time;

5,The jack has a high degree of automation, convenient and flexible operation, with automatic operation, semi-automatic operation, single point adjustment, manual operation and other operations.LCD display, touch screen display, button operation panel display, very intuitive.And the control system is equipped with self-correction protection procedures, even if the misoperation will not cause accidents;

6,Using this series of simple unfixing Holding -latch hydraulic Jack, the construction period is short, the cost is low, the economic benefit is good.
