Lifting Construction of ZAT18000H All-Terrain Crane Escorting Yu Refinery Overhaul Project

Loess Plateau in Northern Shaanxi in August，The high temperature is still roasting。It is located in the Yulin refinery area on the edge of the Maowusu Desert.，182-ton vacuum tower（C-501）The hoisting plan is in full swing.，It is Zoomlion that undertakes the important task of hoisting this time.ZAT18000HAll Terrain Crane。

The construction difficulty of this project is the vacuum tower.（C-501）Hoisting，Vacuum tower diameter 5.2 meters，Height 59.9 meters，Equipment weight 182 tons，It is planned to be lifted in place in three sections.，The heaviest of these, the middle section, weighs 95 tons.，The hoisting height is 61 meters.，Lifting span up to 30m。After accounting according to the actual conditions on site and the performance and parameters of the crane，Due to the narrow scope of construction，The Crawler Crane cannot be used.，After careful study，The hoisting team of the project decided to use the 1800 ton all-terrain crane with flexible operation to complete the hoisting work.。

In order to successfully complete the lifting operation，The project department plans in advance、All-round consideration，Lifting team seize the time、Speed up the progress，Carry out detailed hoisting planning，Elaborate preparation of hoisting scheme and crane walking site treatment scheme，The hoisting scheme shall be submitted to the Company for approval in advance.。On the day of hoisting，Person in charge of site and safety、Technical and other management personnel enter the site in advance，Confirm each preparation work before hoisting item by item，The trial lifting shall be carried out in advance to ensure that the safety index requirements are met.。

Small site and big difficulty，1800-ton all-terrain crane shows its power。18 August 3:45 p.m.，Accompanied by a roar.，The person in charge of the project gave the order，Formal hoisting of the middle section of the vacuum tower，Main crane of 1800t Truck_crane/ 'target='_blank' style='color:blue;'>Truck Crane，350TTail sliding with Truck and crane，The middle part of the sleeping tower on the ground，Stand up slowly like a giant，Straight into the sky and vertically butted with the lower section of the vacuum tower，Successful completion of lifting and assembly of the middle section of the vacuum tower。After docking and positioning are completed，Four welders immediately carried out butt circumferential welding.，It ensures that the node target is completed on time with high quality.。The end section of the vacuum tower was also hoisted on August 20.。

The amount of work involved in the upgrading and reconstruction project of Yulian is as follows:：Process pipeline: 60,000 inches，Steel structure 500 tons，170,000 meters of electrical instrument cables，80%Removal of old pipelines、Internal modification of 22 sets of old equipment、Installation of 5 large vertical equipment、Replacement of 75 heat exchangers、47 pumps，All replacements need to be completed within two months.。Zoomlion crane will also be fighting in the front line.，Contribute to the project construction。
