Crown RR 5700 Series Features Traction Control System

Crown Equipment, New Bremen, Ohio, has unveiled the Crown RR 5700 Series of reach trucks, which the company has developed to deliver greater material-handling productivity, efficiency, and safety. Specifically engineered for narrow-aisle warehouse environments, the Crown RR 5700 features a traction control system, enhanced execution of load-handling functions, and quick lift and travel speeds. The RR 5700 Series is offered in reach heights greater than 36 feet with lift capacities of 4,500 pounds. The series is available with AC-powered drive and hydraulic systems and in a double-deep reach version called the Crown RD 5700.

Crown notes the 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 OnTrac 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.

According to Crown, the RR 5700 travels 7 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.

To enhance operator comfort, the reach truck includes a suspended floorboard that absorbs vibration, and trucks can be outfitted with a ThermoAssist 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 operation. Crown reports 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.

Available as an option, a rack height selection feature allows operators to stop the forks at a specific rack level with the click of a button. The 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.
