Correct selection of Stockmaster requires a knowledge of both the operating environment and the application.
Read the Operating Environment and Application data and then choose your size from the chart at the end of this page.

The following information is a guide. For further help, consult your dealer.

The Operating Surface.
Navigator requires a smooth and level surface for operation.

In the mobile mode, the feet of Navigator clear the operating surface by approximately 30 millimeters. A typical concrete slab floor provides a suitable operating surface, however areas around sumps, drains or other variations in level exceeding 30 millimeters will not permit correct operation.

To ensure clearance of the operating surface check the area to be used

The Operating Space.
Navigator is highly manoeuvrable and is suitable for use in confined spaces.

See formula below for calculation of the minimum space requirement for navigation between a service aisle and a picking aisle.

Also check for;
Height of doorways and overhead structures.
Space for turning at the end of storage bays.
Space for movement in aisles and between machinery and fixtures.

Principal Applications.
Picking and Shelf Stocking
Navigator is ideal for this application as it provides excellent manoeuvrability to maximise the speed of relocation between fixtures.

For safe working, items to be handled should be light weight (5 kg maximum) and able to be carried in one hand. (For large or heavy items see Stockmaster LIFT-TRUK.) An exception is Navigator sizes 4 and 5 where suitably sized items may first be placed on the platform before transferring to shelving or retrieving from ground level.

If the Operating Surface is poor, Stockmaster Tracker can be suitable dependant on the available Operating Space.

Maintenance or Inspection
This application is generally best serviced by Stockmaster Tracker, however in confined spaces on good quality floors, Navigator is the preferred choice.
