Maneuvering

Aisle Widths

Aisle dimensions are key variables that need to be assessed while planning routes within a facility and should be indicated on the Facility Route Map. The truck’s Obstruction Sensor fields require clearance both in front and on the sides of the truck to maneuver through aisles. Table5 lists the Minimum Aisle Width (MAW) requirements for sing le-lane aisles (one Raymond Courier, see Figure9 ) and double-lane aisles (two Raymond Couriers, see Figure11) under the following conditions:

•With Hazardous Zone: Hazardous Zones will be created in the aisle.

•Without Hazardous Zone: The aisle has enough space that Hazardous Zones can be avoided.

Dimensional specifications include the consideration of the truck’s Stop Field, load width boundary, training accuracy, and path accuracy of the automated truck.

All applications must be taken into consideration before planning and training a route. Although this informat ion is in reference to aisles, it also applies to other areas in the facility wh ere limited clearance is a concern (for example: doorways, walls, partitions, ramps, and so forth).

NOTE: Speeds are reduced in Hazardous Zones. For optimum performance, use wider aisles and avoid aisles that result in the creation of Hazardous Zones.

NOTE: Single-Lane aisles can be used for 2-way traffic when trained as an Intersection Zone.

NOTE: Minimum Aisle Width (MAW) values are calculated for a truck with a centered 40 inch wide load bo undary. Additional clearance is necessary when a larger load boundary is used. To determine the additional clearance for a greater than 40 inch wide load boundary, use the following formulas.

•Additional Clearance without Hazardous Zones

•Double-Lane: 2 x Actual Load Width – 80

•Single-Lane: Actual Load Width – 40

•Additional Clearance with Hazardous Zones

•Double-Lane: Actual Load Width/2 – 20

•Single-Lane: Unaffected

Siding Drop-Off (Model 3010 only)

A siding drop-off is when a pallet(s) is dropped to one side of the aisle, allowing traffic to contin ue on the opposite side of the aisle. Ideally, the through traffic path has no Hazardous Zones and has sufficient clearance to the adjacent rack and loads to allow full speed travel. See Figure13 . Depending on the aisle length and width, multiple pallets may be dropped on the same side of the aisle. The truck’s configuration, including the length of the forks and the operator’s compartment size, has a direct impact on the minimum spacing between siding drop-off locations. Refer to the dimensions provided in Table5 for Double-Lane aisle widths as a reference for the minimum aisle width requirements for siding drop-offs.

NOTE: Additional distance is required on approach due to the length of the stop field and the proximity to the rack.

Inline drops may be required if there is not sufficient aisle width to drop a load and have through traffic.
