Erecting a storage tank using Hydraulic Jacking Systems / Equipments is the safest way. Most work is done at ground level reducing risks of accidents. There is not a single reported mishap in the last 20 years which goes to prove its credibility in being the safest and most preferred method for storage tank construction, discarding the need for a tall boom crane

Welding inspectors can now conduct ultrasonic or other non-destructive tests on welds at ground level, facilitating ease of inspection and hence better quality control. No more climbing up to precarious positions for welding inspectors !
* No crane required
* Faster erection
* Lesser manpower required
Cost of the Hydraulic Jacking Systems / Equipments can be recovered after constructing 3 to 4 storage tanks or by erecting about 1200 tons of tankage. Hydraulic Jacking Systems / Equipments cost is around USD 50 per ton for 1200 tons. Example : Tank of 30 m diameter weighing about 300 tons needs 30 jacks of 12 ton each. Full cost of Hydraulic Jacking System / Equipment is recovered in 4 such tanks.

The jack is a fail-safe device. Even in the event of hydraulic seal, the mechanical grip jaws prevent the jack from moving downwards and will hold the jack at the same position on the trestle rod. In case of a hose rupture during lifting, lifting should be stopped and the hose replaced. The jacks do not slip downwards with the load even if the hose bursts. Prior to dispatch, each jack is load tested at 1.5 times its rated capacity and kept under load for 3 to 5 minutes. On customer request, the load test can be witnessed by a Third Party Inspection agency like Bureau Veritas, SGS, Germanischer Lloyd or the like. Each jack has two pairs of case hardened grip jaws made of special grade of steel. At any given point of time, either one of the pairs is engaged or locked. During lifting both the pairs are in "locked" position. In this position, the jack can move only upwards. Remove any unsuitable material and replace with suitable fill, then thoroughly compact fill inside the concrete ring or crushed stone ringwall, and lay a layer of minimum 75 mm thick compacted, clean sand above the fill, as per Figures B-1 and B-2 on Pages B-3 and B-4 of API 650 (See below). The bearing pressure below the trestle base plate above the tank bottom plate shall be minimum 1.45 N / mm2, else the trestle base plate surface area shall be made larger.
On customer request, the stability of tank under jacking is checked by design calculation considering the diameter, height, weight, and number of jacks used. The maximum safe wind speed at which it is safe to jack up a tank is determined using these calculations. During lifting of a tank using jacks, an oil cushion if formed since all jacks are connected to each other hydraulically. This implies that no single jack will be subject to excessive load. In the event of uneven lifting, which at any time can be to the maximum extent of the stroke length of the jack, which is 100 mm, individual jacks can be shut off using a stop cock valve to make any adjustments during lifting. On specific request, motors and starters for powerpack are supplied with "CE" mark.
Load on hydraulic jacks SHALL NEVER EXCEED the safe working load. Arc spacing between trestle SHALL NOT EXCEED 3.00 m, otherwise contact our Technical support. If the ratio of Height to Diameter is more than 1, contact our Technical support. Safe bearing capacity above the tank bottom plate (below the trestle base plate) shall be minimum 1.45 N/mm2, otherwise contact Technical support. Overload or misuse of Jacking equipment can cause PROPERTY DAMAGE, BODY INJURY OR DEATH. Before selecting the type and number of jacks for any tank project, or before operating the jacking equipment, read our instructions and this Safety section carefully, and understand the information contained therein.
A specialist can be deployed to site to train customer’s site personnel in the commissioning and use of the hydraulic jacking equipment.
On customer request, the stability of tank under jacking is checked by design calculation considering the diameter, height, weight, and number of jacks used. The maximum safe wind speed at which it is safe to jack up a tank is determined using these calculations.
Operation manual is available on this site. A video demonstration showing step-by-step set-up procedure and operating instructions for the jacking equipment, is also available in this site.
On customer request, drawing showing hose connection for a specific tank can be provided. A sample drawing for a tank is available for reference on this site.
Appropriate grade and type of hydraulic oil to be used for the jacks depending on the ambient temperature is suggested. Different Voltages and Frequency of Electric Supply for Different Countries Motors with different voltages and frequency can be supplied to suit the power supply available in the customers’ project location.
The basic spares can be ordered with the jacking equipment. By and large, additional spares are seldom required, however, they are promptly dispatched by courier to any part of the world at short notice.
