Traction Control System is First-Ever for Pantograph Reach Truck
NEW BREMEN, Ohio (May 21, 2009) – Crown Equipment, one of the world’s leading lift truck manufacturers, unveiled today the Crown RR 5700 Series of technologically advanced reach trucks that is intended to deliver greater material handling productivity, efficiency and safety. Specifically engineered for the unique challenges of a narrow-aisle warehouse environment, the Crown RR 5700 features the industry’s first traction control system, enhanced execution of load-handling functions, and the fastest lift and travel speeds among other available reach trucks.
The Crown RR 5700 includes several enhancements that improve operator confidence and control in performing challenging moves at heights greater than 36 feet. Most notably, the Crown RR 5700 is the first-ever pantograph reach truck with a traction control system designed to assist the truck from slipping on wet, dusty or sealed floors. The patent-pending Crown OnTracTM Anti-Slip Traction Control uses the integrated Crown Access 1 2 3® control system to compare the truck’s speed with the number of revolutions per minute the drive tire is turning to determine whether the truck has lost traction. By reducing tire spin during acceleration and preventing wheel lock-up during braking, the system reduces slipping and sliding. This decreases tire wear, increases efficiency, helps reduce the risk of accidents and product damage, and improves operator confidence in slick conditions, such as refrigerated or freezer applications. Other enhancements include:
– Lift and Travel Speed: The Crown RR 5700 travels seven percent faster, lifts 18 percent faster and lowers 16 percent faster than similar reach trucks. Cornering speed control in the Crown RR 5700 slows the truck’s speed as the steer angle increases so that turns can be negotiated safely. Truck performance settings can be customized to individual operator preferences.
– Operator Comfort: The Crown RR 5700 includes a suspended floorboard that absorbs vibration, and trucks can be outfitted with a ThermoAssistTM package for improved operator comfort in refrigerated or freezer applications. S-Class trucks include a padded seat, which can be adjusted to three different positions to allow drivers to sit, lean or stand during truck operation. The S-Class operator compartment is 45 percent larger than those on other reach trucks and features a special footrest that offers postural relief while promoting a safe operating position. These ergonomic advantages, in addition to an adjustable arm rest, work together with safety features such as an entry bar safety switch and position hold to promote safe lift truck operation while maximizing productivity.
– One-Touch Rack Height Select: Available as an add-on element, a rack height selection feature allows operators to stop the forks at a specific rack level with the click of a button. While other systems require users to choose from two entry heights for each rack level: one for pallet pick-up and a slightly higher height for pallet put-away, the Crown RR 5700’s One-Touch Rack Height Select senses whether the truck is carrying a load and adjusts rack entry height accordingly. A tilt-position-assist function further facilitates pallet entry at upper rack levels by leveling the forks.
“The Crown RR 5700 is a major step forward in the use of the truck’s intelligence to improve performance and control,” said Crown Product Manager Maria Schwieterman. “The entire package is really more than meets the eye as the Crown Access 1 2 3 operating system provides a platform on which we can drive innovations such as the unique traction control system and rack-height select feature. When combined with the Crown InfoLinkÒ system, data can be collected and analyzed across multiple trucks via the Crown InsiteTM approach to improving fleet management and paving the way for true business intelligence within material handling environments.”
The Crown RR 5700 Series of trucks is offered in reach heights greater than 36 feet with lift capacities of 4,500 pounds. The Crown RR 5700 is available with AC-powered drive and hydraulic systems, and in a double-deep reach version called the Crown RD 5700.
