Since 1988, Vulcan Industries, Inc. has offered the Mensch Crawler™ Bar Screen as the standard of excellence in operation and reliability for mechanical screening applications around the world. We bring a level of experience, unrivaled in the industry, for designing and manufacturing customized bar screens for new and existing facilities.
Each Mensch Bar Screen is custom built to the exact specifications of each project. The unique frame design extends from the channel invert to the top of the unit providing structural integrity and reduces installation costs and the chance for installation error. Partial frames are also available. To guard against corrosion, reduce maintenance, and ensure years of productive operation, the rugged frame and the structural components and shafting is fabricated from stainless steel. The low maintenance pinrack/cogwheel drive system eliminates chains, lower sprockets and the need for permanently submerged moving parts.
Prior to delivery, each Mensch Bar Screen is fully tested by our expert staff to ensure proper operation when it reaches your facility.
Electrical Controls
Each control panel we provide is designed and manufactured by our in-house electrical shop to meet the specifications for each particular project. Our panels are UL listed and can be labeled UL 508A or UL 913. Prior to shipment, each panel is fully assembled and tested. Panels can be installed as free standing, wall mounted or screen mounted. Controls can also be installed into existing MCC buckets when clearance issues prevent the installation of a new control panel.
Drive System Options
Vulcan Industries offers electric and hydraulic drive systems for the Mensch Crawler™ Bar Screen. Submersible electric and submersible hydraulic drive systems are available for deep channel applications.
A two-speed drive system is an option for all electric and hydraulic drives to provide a faster cleaning rate (during first flush events). As needed, the system increases the rake speed to clear debris rapidly during periods of higher screenings volume.
For wider screens, a dual synchronized drive system adds the power and reliability of two drives to the rake arm assembly.
Rake speeds available from 20 fpm to 40 fpm. Please contact Vulcan if faster speeds are deemed necessary.
Post-Screening Devices
In addition to primary screening devices, Vulcan Industries offers a wide array of post-screening and dewatering devices. The Model EWP Washing Press and Model ESP Screw Press provide dewatering and transport for screenings. Connect multiple screening devices to a single post-screening dewatering and compacting device with a conveyor from Vulcan Industries. To assemble the most cost effective and efficient array of screening and post-screening devices, please contact your Vulcan Industries representative.
