Enerpac Helps Erect Worlds Tallest Observation Wheel in Las Vegas
To help erect the 550-foot tall Las Vegas High Roller observation wheel including installing the massive rim sections that support 28 observation cabins, each 20 feet in diameter, each weighing 25 tons and each accommodating up to 40 people. The rim consisted of 28 different sections each weighing a massive 45 tons. The challenge was to lift, assemble and then rotate the huge rim sections so the next section could be assembled, thus allowing the wheel to take shape.
Working with American Bridge Co. and its consulting engineer Zieman Engineering, Enerpac developed and supplied the Hydraulic Rotating Mechanism (HRM) necessary to assemble and erect the rim sections. The HRM was mounted on a 71-foot temporary holdback tower and was used to grip, hold and turn the rim while it was being constructed--and safely hold it in place during construction. The HRM consisted of six gripper boxes (three per side of the rim) which were operated by two hydraulic power units and a single computer control station, resulting in a 750-ton gripping, holding and moving capacity.
