Animated video of ZCC3200NP crawler crane lifting the 1308-ton reactor for Section 1 of the hydrogenation unit

The main equipment to be lifted in this project is the reactor of the first stage of the 6 million tons/year diesel hydrogenation unit; the net weight of this equipment is 1,308 tons, while the total lifting weight amounts to 1,508 tons. As the main crane for this project, the technical staff and service engineers from Zoomlion developed a detailed lifting plan for the ZCC3200NP crawler crane: using a main boom length of 108 meters and a jacking radius of 37 meters, with a lifting work radius of 24 meters; another crawler crane was used to assist in guiding the load. At 8:18 a.m. that day, under the golden light of dawn in Dalian’s Changxing Island, the lifting operations began. The ZCC3200NP crawler crane slowly lifted the equipment off the ground; through adjustments such as changing the boom angle, raising the hook, moving the crane horizontally, making fine tweaks, as well as moving the rear part of the crane and rotating it 90 degrees in place, the hook was lowered smoothly, allowing the target – the first-stage reactor of the diesel hydrogenation unit – to be placed firmly on its base. The entire lifting process represents a significant challenge for the performance of the front and rear units of the ZCC3200NP crawler crane, as well as for its intelligent coordinated control system. According to the service engineer at the lifting site, \"the outer diameter of the first-stage reactor in the 6 million tons/year diesel hydrogenation unit is approximately 5 meters, its height is about 51.368 meters, and the total lifting height is 110.9 meters.\" The rated working load of this crane is 1,913 tons, with a load factor of 78.8%, which imposes very high requirements on its lifting performance. Not only that, lifting is also affected by weather conditions; high wind speeds can directly impact the stability of lifting operations, increasing the difficulty of construction. ”
