Ch 8 material handling Presentation Transcript

  • 1.
    • Important concepts in Material Handling
    • Material Handling
    • Unitization
    • Palletisation
    • Containerization
    • Inter-modal transportation and related benefits
    • Lead-time
    • Cost
  • 2.
    • Material handling
    • Definition: “the art & science of moving, packing & storing substances in any form”
    • Receiving, moving, storing, dispatching activities
    • Impact on Quality, cost [capital as well as running], Delivery & Safety
    • Objectives of material handling
    • Movement minimization
    • Cost minimization
    • Time minimization
    • Commonly used equipment - forklifts, EOT Cranes, hoists, pulley blocks, trolleys, railroad cars, conveyers, ropes, slings, carousels, sortations, robotics
  • 3. Unitization, unit loads
  • 4.
    • Benefits of Unitization & unit loads
    • Ease of movement
    • Standardization of handling equipment,
    • methods and training
    • Reduction in time and cost of handling
    • Inbound shipment checking is simplified
    • product protection is improved
    • Examples: bottles in crates, steel sheets in coils, steel ropes in coils etc. container is an example of unit load.
  • 5.
  • 6. Palletization Pallet is a Unit load platform
  • 7.
    • Benefits of Palletization
    • Unit load is secured on a pallet, pallet provides a secure base for the unit load
    • Leads to containerization, container is a (unit load) self contained, ie., unitized and palletized, shipping unit
    • Facilitates use of standardized handling equipment like a forklift or a crane
    • Palletized unit loads bring down time of handling and cost of handling
    • Ensures safe handling
    • Product is well protected
  • 8.
    • Types of pallets
    • Wooden pallets
    • Plastic pallets
    • Composite pallets
    • Refrigerated pallets: self-contained shipping units for refrigerated materials
    • Pallet pools
    • central pools to collect pallets and issue pallets to global business
  • 9. HOIST EOT
  • 10. pulley block forklift
  • 11. conveyers
  • 12. Automatic Guided Vehicles
  • 13.
  • 14.
    • Principles of material handling
    • Planning - high impact on cost
    • Integration – material handling decision should be part the corporate strategy-foundation, floors, layout, product
    • Standardization – handling methods, equipment, software
    • Work – minimum handling
    • Ergonomics – tasks, equipment and human beings
    • Use of gravity- always use gravity to advantage
  • 15.
    • Unit load- handle only in unit loads
    • Space utilization- use space and not area, EOT rather than F/Ls
    • System – integrate handling & storage (O/H tanks and pipe lines) and form Operational Material Handling System
    • Auomation - need based
    • Environment - explosive?
  • 16.
    • Signs of Poor Material Handling
    • Cluttered floor
    • Accidents
    • Excess inventory
    • High waiting time, high Through Put Time, poor flow of material
    • Excessive handling
    • Poor quality of product, high scrap
    • Lack of standardization
    • Poor use of skilled labor
  • 17.
    • Material handling system
    • Types of Material Handling Systems: Manual, mechanized, automatic, computerized
    • Elements of the system: human, equipment, storage, packaging
    • Equipment selection & Purchase
    • Full utilization of existing equipment
    • Overall cost reduction
    • Standardization
    • Integration with current system
    • Alternate methods – production should not halt
  • 18.
    • Facility limitation, building, floors etc
    • Future plan
    • Maintenance support
    • Life cycle cost
