Spotlight on Success: Hoover Dam Modernization

Hoover Dam

Magnetek’s Material Handling team spent time working inside the Hoover Dam’s concrete structure alongside Precision Crane & Hoist Services of Nevada to modernize the facility’s aging AC static crane controls with state-of-the-art control technology developed by Magnetek.

The Hoover Dam has two power plant wings, one located in Nevada and one located in Arizona. Each wing is 650 feet long and rises nearly 300 feet above the foundation of the power plant. Two 300-ton cranes are located inside each power plant wing and are used to move and maintain the 17 main vertical hydraulic turbines housed within the wings.

The Hoover Dam Power Plant, one of the United States’ largest hydroelectric installations, generates approximately four billion kilowatt-hours of hydroelectric power on average each year, enough to serve 1.3 million people in Arizona, Nevada, and California.

Magnetek controls were retrofitted on each of the four 300-ton cranes over a seven-month period, which began in December 2014. The new crane control systems utilize Magnetek’s technologically advanced drives and radio controls, providing crane operators at the Hoover Dam Power Plant with improved productivity, safety, and reliability.

The Benefits of Variable Frequency Drives

Benefits of VFDsPerhaps no other technological development in the past 40 years has done more to revolutionize overhead crane design than the AC Variable Frequency Drive (VFD). Today’s Variable Frequency Controls and Flux Vector Motor Controls have become the industry standard for crane control.

AC Variable Frequency Drives provide greater reliability, enhance performance, improve production throughput, prolong equipment life, and reduce maintenance costs, parts, and personnel in a variety of ways, including:

 

  • Reducing the characteristic high starting currents of AC induction motors
  • Minimizing the shock effect on both the load and the equipment
  • Offering features, such as programmable acceleration and dynamic braking that:
    • Produce softer stops and starts
    • Assure smooth transitions between speed steps
    • Reduce brake wear and required maintenance
    • Embedded Anti-Sway control

Crane-specific firmware, drive support tools, and wired/wireless communication with various peripheral devices provide valuable monitoring, status, performance, and diagnostic information.

Features are built-in and individually selectable:

  • Reverse Plug Simulation
  • Stall Prevention
  • Inching Control
  • Weight Measurement System
  • Micro-Positioning Control
  • Static Stepless Simulation

No two applications are the same. Variable Frequency Drives provide users with a variety of operating modes and a wide range of options. Most single-speed squirrel cage motors can be controlled by VFDs, including conical-rotor motors used by many European hoist manufacturers. Multiple control modes (two, three, and five step or infinitely variable speed) allow for changing the operation to suit the needs of specific applications or the desire of individual operators. A wider range of selectable speed choices (up to 1500:1) are available to the user compared to the fixed speed ratios provided by the typical two-speed motors (2:1, 3:1, or 4:1) or micro-drives (10:1).

Safety is built into modern Variable Frequency Drives. They include features that:

  • Reduce the possibility of lifting an over-capacity load
  • Minimize or eliminate dangerous load swing
  • Prevent overheating of the motor
  • Detect and minimize rapid increases in motor torque
  • Provide safeguards that limit unauthorized modification of drive parameters or programming unsafe parameters.

Today’s technology provides a cost-effective means to make your crane more efficient, productive, and safer.

Spectrum Analysis: Why Does It Matter?

Whether you are looking to diagnose current RF issues, expand your current radio control operations, or commission a new facility, spectrum analysis helps you navigate what’s “in the air,” reducing RF interference and costly troubleshooting. The RF Spectrum in the industrial workplace has been become increasingly crowded. Modern control panels, wireless networks, bar code readers, and two-way communication devices create signal traffic in a facility, all of which interfere with radio control systems.

One of Magnetek’s customers purchased a radio remote control system and after installation, experienced frequent dropouts, impacting workplace efficiency. Magnetek completed a spectrum analysis and was able to diagnose the interference and recommend a solution—a frequency change from the 900 MHz band to the 2.4 GHz band. This solution optimized the facility’s radio communications.

Our Spectrum Analysis Service includes a scan of your entire facility or a single area, indoor or outdoor. An average of 45-60 scans can be completed in up to an eight-hour period, five scans per location. Locations are determined by facility layout with a minimum of one location per operating area, typically three locations per bay. Scans are conducted on all the commonly used operating frequencies. You will receive:

  • Analysis of our findings
  • Scan screenshots
  • Identification of potential interference
  • Frequency recommendations

Whether an existing system or new radio control system installation, Magnetek’s Spectrum Analysis Service is the easiest way to navigate your facility’s airwaves.
