AIRMATIC Introduces New Line of COUGAR® Precast Concrete Vibrators

AIRMATIC is pleased to announce we are introducing a new line of long-life vibrators for precast concrete applications, manufactured by its Core Product Supplier and global leader in industrial vibration technology, MARTIN ENGINEERING. The new line of COUGAR Concrete Form Vibrators from MARTIN ENGINEERING is built with heavier-duty materials for internal components than most competing designs, and utilize Class H windings and a rigid alloy frame to withstand maximum force output levels for longer sustained periods. Designed to replace current vibrators sold for these demanding applications, the units are engineered with external bolt patterns compatible with conventional form brackets, creating a secure fit that allows the concrete to settle quickly for even distribution without air pockets, resulting in greater reliability and service life for a lower overall cost of operation.

“Most concrete form vibrators have Class F windings with a lower temperature rating,” stated David Ruggio, Vibration Product Specialist at MARTIN ENGINEERING. “Class H windings are able to withstand a higher internal temperature, allowing the units to run longer without having to be serviced or replaced as often.”

The vibrators are housed in a totally enclosed, non-ventilated (TENV) case and feature an electric rotary motor as large as 230V to 460V (3Ph / 60 Hz), running at 3,450 RPM and producing as much as 3,000 lbs (1,360.7 kg) of force. While other manufacturers typically specify that vibrators should not be operated continuously at maximum output, MARTIN Vibrators are rated for continuous duty at any setting. This is aided by the Class H windings, which are triple dipped and shock resistant, making the capable of operation under sustained high internal temperatures.

CEMA Announces New Ranking Standard for Belt Cleaners

The Conveyor Equipment Manufacturers’ Association (CEMA) has issued a new standard for the ranking of conveyor belt cleaners, a long-awaited publication that provides performance-based guidelines for specifying belt cleaners by establishing a specific formula for determining the level of difficulty in a given application. The purpose of rating the application difficulty is to provide appropriate belt cleaner selection, resulting in a suitable choice so both end users and suppliers can be satisfied with the outcome. The new standard is included in the 7th edition of the CEMA book, Belt Conveyors for Bulk Materials, in the Belt Cleaning section.


According to CEMA’s website, “The Classification of Applications for Bulk Material Conveyor Belt Cleaning” has been established to provide a uniform method for determining the application class of any individual belt conveyor. “For end users, the standard is an objective means of determining a cleaner’s suitability for the plant’s material and operating conditions, allowing them to specify a cleaner most likely to meet their needs,” stated Daniel Marshall, Product Engineer of MARTIN ENGINEERING. “It also provides a means to check a sales rep’s recommendations against the application requirements, allowing users to compare ‘apples to apples’ in terms of duty rating, performance, and pricing.” Manufacturers voluntarily specify into which class their particular designs fall.

Conveyor engineers are also expected to benefit from the new standard, as they can now specify a belt cleaner rating without relying on a manufacturer’s proprietary technical information. For belt cleaner manufacturers such as MARTIN ENGINEERING, CEMA 576 is a way to confirm that a cleaner matches the application requirements, and thereby assures Customer satisfaction. “An objective method to determine cleaner suitability helps designers by allowing them to specify a cleaner based on its performance and durability,” Marshall continued. “Now subjectivity can essentially be removed from the cleaner purchasing decision to concentrate on system performance. Suppliers can now include a clear ranking on data sheets and other literature, allowing Customers to review and compare products.”
