Putzmeister America, Inc. Introduces Innovative TechnologyExtended Range EBC Enhances Boom Reach and Maneuverability
STURTEVANT, Wis. (August 24, 2006): As an addition to its Ergonic® Boom Control (EBC) technology, Putzmeister America’s new Extended Range EBC technology enables the company’s two large roll-and-fold concrete boom pumps to maximize their reach and achieve a greater working range.
Ergonic technology was developed by Putzmeister to facilitate the highest performance from its concrete boom pumps. EBC is but one module of this very advanced control system and it ensures that the boom moves in a smooth, controllable manner.
Putzmeister’s Extended Range EBC technology enables the ‘A’ and ‘B’ sections of the 58- and 61-Meter booms to operate in previously restricted areas. In Extended Range EBC mode, the ‘A’ section of the boom can be positioned within a 170-degree range to access difficult-to-reach areas. Without this technology, these roll-and-fold models achieve a maximum of 120-degrees with all boom sections in ideal positions.
“The expanded capabilities of the ‘A’ section boom significantly increase the working envelope. The new geometry of the booms results in the tip section flattening to a more horizontal position for reaching previously inaccessible areas, such as between floors,” says Travis Nonn, Customer Support Rep and EBC Specialist at Putzmeister America. “Flexible maneuvering of the four-section boom can even be accomplished while set up right next to a building and right in front of the cab.”
Extended Range EBC has also been engineered to work with Putzmeister’s One-Sided Support (OSS) outrigger system. OSS allows the operator to reduce the machine’s outrigger extension on one side for setup in tight spaces, while operating within a defined working range.
Extended Range EBC uses pressure transducers to monitor the forces on the ‘A’ and ‘B’ hydraulic cylinders, which have been calculated to maintain the machine’s stability with or without OSS. The system will not allow the operator to position the boom in an unsafe working envelope. Redundant sensors are employed to prevent operation if a failure or an inconsistent reading occurs. However, the operator can still return to a standard boom configuration.
A plug-in connection activates EBC, which then engages the Extended Range capabilities. Simply unplugging the connection returns the boom to non-EBC or routine operation
In addition to Extended Range EBC, the patent-pending design of OneTouchTM is also a major part of EBC. OneTouch is the first control system in the industry where a single joystick coordinates the movement of all boom sections and slewing in tandem, while keeping the end hose level.
The present components, available on Putzmeister equipment for several years, remain the same. However, specially designed software now works in conjunction with hydraulic and electronic sensor systems to achieve the benefits of this latest technology. Further advancements trouble-shooting methods are also underway at Putzmeister.
