Enerpac lifts Waste-to-Energy project in UAE
Leading Turkish heavy lifting company, Hareket, relied upon Enerpac strand jacks to install superheater and vaporisation modules at the first United Arab Emirates waste-to-energy (WTE) facility in Sharjah. Generating up to 30MW of electricity, the facility will contribute to Sharjah’s effort to achieve, ‘zero waste-to-landfill,’ and the UAE to meeting its 2021 goal of diverting 75% of solid waste from landfills.
Hareket undertook all heavy lift engineering and supervision of the strand jacking works. This involved installing two temporary lifting platforms each featuring two Enerpac 200t capacity strand jacks per platform. The strand jacks were used to lift eight 77t superheaters and two 20t vaporizer modules up to 30m. Accurate positioning of the 16m high modules was synchronised by a single operator using a wireless controller on each platform.
“This was our first deployment of the Enerpac strand jacks, and they performed very well,” says Samet Gürsu, operations director of Hareket Heavy Lifting & Project Transportation Co. “It demonstrated the flexibility and innovation that Hareket brings to heavy lift projects where traditional lifting methods are impractical.”
The 200t capacity Enerpac strand jack acts like a linear winch. A bundle of steel cables or strands are guided through a hydraulic cylinder; above and below the cylinder are anchor systems with wedges that grip the strand bundle. By stroking the cylinder in and out while the grips are engaged in the anchors, a lifting or lowering movement is achieved.
The motion of the cylinders is driven by hydraulic power packs. The Enerpac SCC software program synchronises the motion of the strand jacks and adjusts the motion to the loads per lifting point.
The waste-to-energy facility will process around 37.5t of municipal solid waste per hour and will be located adjacent to the existing Bee’ah’s existing material recovery facility inside the Bee’ah waste management complex in Sharjah, where the Emirate’s waste is collected, sorted and recycled and residual waste is sent to landfills. The project is also estimated to offset approximately 450,000t of
