Scrubber Dryers and Inclusion

Thanks to their design, concept and integrated driver assistance systems, scrubber dryers of the Rotan series are ideally suited as a workplace for the easy cleaning of large traffic areas. The vehicle is ready for use in just a few steps. The intuitive operation gives the driver the necessary sense of security and keeps the focus on thorough floor cleaning. To make it easier for people with disabilities to be integrated into the regular work process, the following sections illustrate tailor-made solutions that put the individual's employability at the centre.

Precise Control of the Scrubber Dryer

The steering is geared down in a ratio harmoniously matched to the vehicle and allows sensitive yet precise manoeuvres with all the less effort. The use of a double-stage gear drive makes the technical steering design elaborate, but free of play in the long term. The reduction ratio is chosen so that drivers can intuitively negotiate curves and turning radii. The steering wheel is ergonomic, of high-quality feel and fitted with an easy-to-use steering wheel knob.

Seat for a Fatigue-Free Working Day

The ergonomic seat has a particularly generous seat surface. People of every build find enough room and freedom of movement to adapt their sitting position, even while driving, to a possibly declining physical capacity.

To prevent signs of fatigue, the seat offers ample padding and well-balanced suspension. An adjustable backrest allows the back angle to be individually adjusted to personal comfort.

The backrest extension, fitted as standard, supports the back up to the shoulder blades. Armrests on both sides, which can be folded up when leaving the seat, relieve the shoulders and allow the elbows to rest in a relaxed way during the cleaning run. Armrests also make it easier to climb onto the vehicle and, as a boundary on both sides of the vehicle, give a reassuring feeling of security during the cleaning run. Owing to the high travel speed and the general safety standards of Rotan vehicles, an automotive-grade seat belt is fitted as standard

Safely Driving Around Objects

The brush head is attached to the Rotan chassis by movable ball joints arranged in the form of a horizontal trapezoid. This arrangement enables the brush head to drive around obstacles (e.g. wall corners, pallets, rack feet, table legs, etc.) right along the edge in a cushioned retracting motion, without damaging the objects or the vehicle itself. The narrow chassis width of only 75 cm results, with a working width of 95 cm, in a generous brush head overhang of 10 cm on both sides of the vehicle. A direct view of the brush head during the cleaning run allows work right along the edge with a considerably reduced risk of damage.

The squeegee swivels discreetly around obstacles. Track-guided support rollers force the squeegee to return immediately to its stable starting position. Thanks to the arrangement of the drive axle and the V-shaped brush head, the squeegee could be positioned, protected, under the rear end of the vehicle chassis. This criterion gains importance when reversing with poor visibility, since the rear rubber buffers on the chassis cushion any impact and the squeegee is not affected in any way.

Innovative Battery Pack

A cleaning vehicle not only has to be available for as much of the working day as possible, but ideally also constantly available. The battery technology used in Rotan cleaning vehicles makes this possible. The installed NexSys® block batteries can supply sufficient electrical energy for up to 7 hours. Charging, on the other hand, takes only 4.5 hours. Partial charging is welcome: the charging process can be interrupted at any time and resumed later without damaging the battery. The service life of these special AGM batteries is 40% longer than that of conventional GEL batteries – always at the same depth of discharge (DoD).

Driver Assistance Systems as Standard

The digital system control of the Rotan cleaning vehicles can be adjusted to site-specific and operator-specific needs. These parameters are programmed in cooperation with the customer or operator before the first commissioning.

• transport and cleaning speed,
• ramp-up for braking and acceleration processes,
• voltage monitoring of the battery set under load, and
• freely selectable power levels for both brush speed and suction power.

Travel speed and braking are controlled by a single pedal, as braking is exclusively electric, by lifting the driver's foot. The faster the foot is lifted, the more pronounced the deceleration, down to a standstill within only 20 cm.

The braking energy recovered in this process is used to recharge the batteries. Using only one pedal removes the need to coordinate the second foot and to operate a second pedal.

The further safety features fitted as standard on Rotan scrubber dryers are a horn, an emergency stop switch in the control panel, a rotating beacon, front headlight, indicators and an automatically engaging electric parking brake.
