Simple Hydraulic Jacks for LPG 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.Working principle of simple jack

 Hydraulic lifting device (package unit) is evenly distributed around tank inner wall. Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. Self locking hydraulic jack and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jack, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank (including tank top) to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. The jack repeats the movement and make lifting rod ascend with tank to designated height (spare height for next layer of plate). After butt weld of next layer of wall plates, open upper and lower loosening device and loosen upper and lower clamp to make lifting rod and expansion ring descend to lower expanded and welded rib plate of the next layer of wall plates and then lift. Repeat the process and ascend welded tan till the last layer of wall plates are installed and welded. The installation of the whole storage tank is completed.

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.
