A new addition towering above the landscape is noticeable in City of Powell River’s historic Townsite.
According to a media release from the city, the landmark is a tower crane that general contractor Graham Infrastructure will utilize during construction of the new consolidated wastewater treatment plant (CWTP). The crane will facilitate construction of all buildings in the plant footprint, aided by a rough terrain crane when needed.
“The tower crane is located where the eastern digester tank will ultimately be constructed and with its massive size, will be able to reach the majority of the building site,” stated director of infrastructure services, Tor Birtig. “Construction of the CWTP is progressing quickly with the bulk excavation and process/treatment building foundation nearing completion.”
The crane, also called a hammerhead crane, is commonplace on construction projects, but this is the first time one of this size has been used on a project in Powell River, the release stated.
The structure also affords the opportunity for training by Powell River Fire Rescue, according to chief Terry Peters.
“As an all-hazard response department, our fire rescue crews need to be ready for many different challenges,” stated Peters. “Technical rescue is an important skill for our members and being able to pre-plan onsite is a valuable tool. We are grateful for the cooperation of the staff at the treatment plant construction site, who provided familiarization of the site and the newly installed crane.”
The Liebherr 290 HC tower crane was erected at the site on August 24. It stands at approximately 55.77 metres (183 feet) from its base to the very top, with a hook clearance height of approximately 48.53 metres (143 feet). It can lift a maximum of 10 tonnes (22,045 pounds), and three tonnes (6,615 pounds) when lifting from the very tip of the apparatus.
