Seven Benefits of Modernizing Your Cranes to VFDs

impulse-series-groupPerhaps no other technological development in nearly 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. Recent improvements in drive technology, such as a new generation of Insulated Gate Bipolar Transistors (IGBTs), sensor-less vector control, powerful microprocessors with flash memory, and improved algorithms, have allowed the downsizing of the power platforms and the inclusion of many high-performance features.

There are numerous benefits of using a VFD to control a hoist or crane, including:

New Product Line: Cable Reels

Magnetek is excited to announce our new line of cable reels!

Our cable reel product line is a superior solution to effectively and compactly manage large lengths of cable. The cable reel is fixed to a specific point, while the cable end connects to the moving part of the equipment.

Magnetek offers both spring driven and motorized electric cable reels, as well as slip ring assemblies. Read more

Project Exploration: Red River Pedestrian Bridge

superior-5Springtime thaws and flooding along the Red River have been annual problems for the cities of Moorhead, Minnesota and Fargo, North Dakota. Occasionally, flood waters have risen up to 40 feet above the river bank and damaged businesses, homes, and surrounding infrastructure. To prevent recurring damage to a pedestrian bridge between the two cities and decrease removal and replacement costs, a 168-foot bridge was commissioned with a self-contained lifting system, including new Magnetek radio remote controls and adjustable frequency drives.

CHALLENGE

  • Introduce lifting functionality to a new pedestrian bridge
  • Decrease likelihood of inclement weather damage
  • Reduce costs for replacement equipment and seasonal bridge removal
  • Coordinate two hoist operations to balance lifting motions

SOLUTION

  • Two 40-ton hoists using Magnetek’s IMPULSE®•VG+ crane control drives and radio remote controls
  • Decreased potential damage opportunities from flood waters or thawing ice
  • Eliminated need for seasonal removal of the bridge by outside contractors
  • Trenched fiber optic cable beneath riverbed to synchronize lifting

Collision Avoidance Systems Increase Safety and Reduce Maintenance Costs

Magnetek’s collision avoidance systems can help prevent accidents before they happen, protecting people, the facility, and the cranes. Our collision avoidance systems prevent crane-to-crane and crane-to-end stop collisions which increases operator safety and reduces system maintenance.
collision-avoidance-systems
Magnetek offers three collision avoidance systems which can be applied to all types of overhead cranes or monorails with adjustable frequency drives, soft starters, or contactor controls. Multiple configurations are available so customers can choose the exact functionality, size, and style to fit their application needs. All Magnetek’s collision avoidance systems are rated IP65 or better. The collision avoidance systems are “fail-safe”, which means that if the sensor would lose power, motion of the crane would be stopped and restricted.

Project Exploration: Newport News Shipbuilding System Upgrade

newport-3As the largest shipbuilding company in the United States, Newport News Shipbuilding (NNS) needs to be at the top of their game to effectively build the most advanced ships in the world. This includes keeping their overhead and gantry crane equipment running at the most efficient levels. Intended to avoid any production slowdowns due to wearing parts, system failures, or crane downtime, NNS scheduled 10-15 year overhauls of multiple cranes and their components.

NNS was able to improve coordination among the system components, enhance facility safety, and minimize downtime by implementing a solid crane modernization program. Properly planning an effective modernization program was key in updating drives and wireless control systems in a timely manner to keep the facility running at a high level.

Product Profile: Fiber Optic Festoon System

Magnetek recently completed a engineered festoon system featuring fiber optic cable for use on an automated monorail application. 

This slideshow requires JavaScript.

The system includes heavy-duty C-Track with double saddle festoon trolleys and flat cable.

The flat cable features fiber optics that use light to convey a signal throughout the system. These glass fiber optics are used instead of a typical copper wire/electrical signal because of the extreme length of the application – approximately 250 feet.  Signals sent over copper degrade over a long distance, so for applications over 200 feet, fiber optic cable is recommended.
