a manner as to reduce accidents and lessenequipment damage.When practicable, move material in a horizontalplane or with the aid of gravity. The ideal liftingpoint of material is at the waist level. The nearerto the waist the material can be picked up ordisposed of, the greater the efficiency.Material Handling EquipmentRequirementsA balanced operation provides for the optimumnumber of people and MHE to complete a specifiedworkload. Too many personnel and not enough MHE(or vice versa) can cause bottlenecks. To produce asmooth operation, you should know how to determinethe MHE requirements for the job.You should consider several factors when selectingthe MHE requirements. If all supplies to be moved arepalletized and squared off for stacking, you may need aforklift truck and operator. However, you might needpersonnel to manually handle some materials. Terrain,location arrangement, design of the building, and extentof the open storage area will also affect MHErequirements. Material characteristics will also affectselection of the required MHE. Some material mayrequire the use of electric or battery-operated forklifttrucks.COMPUTING MHE REQUIREMENTS.– TIhefollowing factors should be used in computing MHErequirements.llllThe volume or size of the operation to beperformed (for example, the number of palletloads to be moved to another area is 48 pallets).The number of units of the volume carried ineach trip (for example, the number of palletscarried by the forklift truck in each trip is twopallets).The average time expended to accomplish around trip (for example, one round trip takes 5minutes to finish).The allotted time to finish the job (for example,the job should take 2 hours to finish).The formula for determining the MHE requirementis as follows:FORMULA: ~xT+AT=RExplanation of symbols;V — Volume or size of the operation to beperformedC — Units of volume carried per trip by MHET — Average expended time to complete aroundtripAT — Allotted time to do the jobR — Equipment requirementUsing the data in the examples above, thecomputation will be as follows:~x 5 + 120 (rein)= 1 forklift truckNOTE: We use the requirement for forklift trucksin the example assuming the distance of travel is lessthan 400 feet).COMPUTING PALLET REQUIREMENTS.—The measurements of a standard pallet is 40 x 48inches. Allowing for overhang (roughly 25 percent),the square feet occupied by each pallet is approximately16(4 ft x 4 ft). If procedures permit stacking of fourpallets high, four pallets are required for each 16 squarefeet of net usable storage space. The formula fordetermining pallet requirements is as follows:FORMULA:Explanation of symbols:S— Net covered storage area, (in SQ FT) used forbulk storage.H—Average stacking height expressed in palletcourse (pallet loads).D—Square feet of floor area occupied by pallet sizewith 25 percent added to compensate for loadoverhang and clearance.R—Quantity of pallets required.For an example, compute the pallet requirementsfor 59,500 feet of usable floor spare with stackingheight of four pallets. The computation is as follows:2-25
