The Crown RR 5700 reach truck includes several enhancements that improve operator confidence and control in performing challenging moves at heights up to 11m. The Crown RR 5700 is the first pantograph reach truck with a traction control system designed to increase traction 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 tyre is turning to determine whether the truck has lost traction.
By reducing tyre spin during acceleration and preventing wheel lock-up during braking, the system reduces slipping and sliding. This decreases tyre wear, increases efficiency, and helps reduce the risk of accidents and product damage. The Crown RR 5700 reach truck also improves operator confidence in slick conditions, such as refrigerated or freezer applications.
Lift and travel speed: The Crown RR 5700 reach truck travels 7% faster, lifts 18% faster and lowers 16% faster. Cornering speed control in the Crown RR 5700 reach truck slows its speed as the steer angle increases so that turns can be negotiated safely. Truck performance settings can be customised to individual operator preferences.
Operator comfort: The Crown RR 5700 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 truck operation. The S-Class operator compartment is 45% larger 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 maximising 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 One-Touch Rack Height Select in Crown RR 5700 reach truck senses whether the truck is carrying a load and adjusts the rack entry height accordingly. A tilt-position-assist function facilitates pallet entry at upper rack levels by levelling the forks.
According to Craig Kenchington, General Manager, Crown Equipment, the Crown Access 1 2 3 operating system provides a platform to drive unique traction control system and rack-height select feature.
When combined with the Crown InfoLink system, data can be collected and analysed across multiple trucks through the Crown Insite approach to improve fleet management, delivering business intelligence within material handling environments.
The Crown RR 5700 series of trucks is offered in reach heights up to 11m with lift capacities of up to 2,000kg. The Crown RR 5700 reach truck is available with AC-powered drive and hydraulic systems, and in a double-deep reach version called the Crown RD 5700.
