#Howwedoit - Installing boiler modules at a combined cycle power plant

Installing #Boiler modules is no easy task, requiring specialist lifts and #Tools with high levels of control and precision. Here we’re showing you exactly #howwwedoit, with an example from a 1.266MW #CombinedCycle #PowerPlant in #Khenchela, #Algeria.

When the boiler modules are unloaded from the #Transport trailer, they are loaded immediately into the verticalisation frame. This specially designed tool, known as the #Strongback, allows the boiler modules to be reorientated as required for their function in the power plant. The strongback gives the required stability to the structure and enables the cranes to position the load, however it needs to be removed before the modules can be installed.

The lift is unique in that the roles of the cranes change mid-lift. Two cranes, the CC22800-1 acting as the main #Crane and the CC2400-1 acting as the tailing crane, start lifting the module and frame, weighing a total 220T. After completing the verticalisation movement, a third support crane is connected to the strongback and the main crane continues to lift the boiler module to remove it from the frame. The main crane turns the module to its final orientation and is connected to the superlift ballast. It can then boom down until the final install position is reached.

The tailing crane stays connected to the strongback throughout the operation and once the boiler module has been installed, assisted by the support crane, it turns the strongback back into the horizontal orientation and returns it to its initial position on the ground, ready for the next module!

This advanced lift combines a wealth of experience in huge #HeavyLifting operations with a highly skilled team, the right tools, and meticulous planning.
