The three principle of material handling are : 1. Principle of Shortest Distance: The minimum operating distance should be as far as possible. A lot depends on the condition of the plant layout, warehouses and production centers. Reduced distance saves labor, time and money in material handling. 2. Principle of Short Terminal Time: As far as possible, there should be no delay in lifting and delivery of material ie unnecessary time is not lost in loading and unloading. 3. Principle of Two way Load: Principle of two-way load: As far as possible, the material should be loaded in both the vehicles coming and going. In other words, the vehicle should not run empty. If the same weight is loaded in the arrival and departure of the vehicle by proper material handing method, then the handing cost can be half. Thus double benefit can be achieved.
