Outline

Faculty of Logistics BUU

Why we need storage, handling system? Customer information Types of business Pallet size, types of material handling How to select the equipment

3

Information needed?

Plant layout Building condition

rack support building dead load, live load

Business, goods, and materials Stock keeping unit (sku) Material handling equipment


4

Selective rack

Designed to support and store goods on pallet, especially for heavy goods

Feature (advantages) raw materials fast picking and shipping from storage locations heavy and big size of goods, standard products engineering design for supporting racks work with reach-in truck and forklift product diversification

7

Structure of selective rack

Post : เสา Bracing : ตั�วยึ�ดเสา Main Beam : คานหลั�ก Cross Beam : คานรอง Base Plate : ฐานเสา


8

Selective rack (disadvantages)

Considerably consumed service truck lane Loss of storage space more than 50%

compared to drive-in rack Storage cost per unit higher than drive-in

rack


9

Drive-in/ drive-through rack

Designed for pallet load, suitable to store a small number of cargo types with high quantity and high turnover rate

Drive-in vs. driver-through drive-in: put-away and picking in the same

direction drive-through: support for both directions

Drive-in

12

Structure of drive-in


13

Features of drive-in

Finished product Support last in first out (LIFO) Little consumed truck service lane, design

more than for 8 levels of depth Storage space more than selective rack

70% Storage cost per unit cheaper than

selective rack


14

Drive-in (disadvantages)

Less stable, non-theoretical design Not suitable for heavy goods, high design

cost Need skilled truck drivers Suitable for reach-in truck (narrow aisle truck) Not suitable to store diversified products,

difficult to find product location and to manage picking/shipping operations


15

Push-back rack

Combination between drive-in and LIFO rack, designed for limited storage space


16

Push back (advantages)

Goods stored in many depth levels trucks need not to get in the narrow storage area,

pulling the pallets from outside

Pallets are stacked, LIFO for putting-away and picking

Good for refrigerated storage, truck need not to get, pulling pallets from outside

Very little occupied truck service lane Storage space more than selective rack 50%


17

Push back (advantages)

Cheaper than selective rack but not for drive-in Designed similar to selective rack, supporting

the pallet load more than drive-in Stable structure Normal forklift and non-skilled drivers can

easily operate Same type of goods should be stored in the

same storage slot


18

Push back (disadvantages)

Higher cost per pallet than drive-in rack High M & R cost coz of rail-and-wheeled

structure Cannot store diversified goods Loss of vertical storage due to stacked rail
