Hoisting scheme of low temperature storage tank

1. low temperature storage tank foundation acceptance

Before installation of the storage tank, the quality and installation dimension of the equipment should be re tested and re examined with Party A. The problems can be solved in time, and the construction can be done after the inspection is qualified.

2. hoisting uses a 16T+25T hydraulic truck crane, gas station 20M3 tank and two 300Nm3/h for hoisting operation.

3. the safety measures before lifting, the car crane station should be close to flat and rammed ground, and pave the sleeper, to prevent the lifting of the crane legs sinking. When the crane and truck are in place, the wire rope and the hook should be checked in time. After passing the inspection, you can use. Hoisting personnel in construction must wear overalls, work shoes, safety helmets and other protective equipment. In the lifting process should do safety measures, so that the tank the earrings on uniform stress, no collision tank, shall not wear body painted, the tank over the lanyard hoisting is prohibited.

4. hoisting operation

1) the wire rope penetrates into the tank in the two rings and lock, the other end is hung on the two crane hook and lock, two cranes and slowly lifting the tank bottom plate, leaving the truck 60 cm to stabilize after the truck slowly moving forward from the working site.

2) lift up with a crane until the cryogenic tank is vertical and move to the equipment foundation. Then the vertical tank is corrected by vertical line, and records are made. Place the anchor bolts in place, then release the wire rope, the crane leave the operation site, and clean up the site after the construction.

3) the allowable error of tank installation shall be in accordance with the following table:

Item number allowed deviation (mm) test method

1 elevation + 5 steel tape measurement

2 center displacement + 5 steel tape measurement

3 plumbdegree X to less than 2H/1000 plumb line measurement

Y is less than or equal to 2H/1000

Note: H is the height of equipment
