SPX Gets to the Nuts and Bolts of Wind Turbine Installation

Demand for wind power is increasing around the world and, with it, the need for wind turbine installations. With supply chain shortages and other issues hampering construction, companies are under increased pressure to work harder and smarter.

SPX Hydraulic Technologies is helping contractors improve work productivity and accelerate wind turbine installation with a line of tools that drive efficiency on the construction site.

Tightening Up Schedules and Costs

The company’s Power Team® Predator™ hydraulic torque wrenches and pumps target the bolting process in wind turbine installation, as well as in gas and oil pipeline installations.

Bolting is a key component in the construction of wind turbines. For every wind turbine, hundreds of bolts are required for fastening tower sections, the foundation and blades.

Tightening and applying final torque settings to the bolts quickly and precisely is crucial to maintaining schedules and keeping labor costs down.

Predator wrenches and pumps facilitate the bolting process by providing greater tool portability, flexibility and continuous operation.

Faster, Continuous Operation

Employing constant horsepower technology, the Predator hydraulic torque wrench pump increases the flow rate across the flow curve. The result is faster tool operation and improved process efficiency — more bolts tightened per hour.

The pump is rated for continuous use. It can be operated non-stop without cool-down periods, alleviating work delays.

“The bolting process may include the requirement to torque a couple hundred bolts at a time. The pump will run continually throughout the day to accomplish this task,” explains Leah Strohman, brand manager for SPX Hydraulic Technologies.

An autocycle feature allows the torque sequence to automatically cycle the wrench until the desired torque value is reached.

“Workers can tighten bolts to preset torque values by simply holding a button down during the tightening process,” Strohman says. “This allows them to reach the torque setpoint faster, further increasing efficiency.”

Designed for Flexibility

The air-driven Predator torque wrench pump is ideal for ATEX-rated (hazardous) control systems and can be used where no electricity is available. It operates more quietly than many competitive products, and meets OSHA and EU-legislated noise abatement requirements.

Quick-connect coupling systems and valving make the pump easier to use — and to move around construction sites quickly. The pump also features an auto-cycle operation that enhances efficiency by decreasing cycle times.

The Predator torque wrenches provide more efficient, faster operation as well, all in two-thirds the size of aluminum torque wrenches.

They can reach required connections easier than standard torque wrenches, making them ideal for applications where space is limited. They can also be operated in a vertical or horizontal orientation.
