Material Handling Systems (ME 40042 / MA/MP 40042)

Unit 1: Introduction to Material Handling Systems

Material Handling Systems refer to the movement, storage, control, and protection of materials throughout the process of manufacturing, warehousing, distribution, consumption, and disposal. Efficient material handling improves productivity, reduces costs, and enhances workplace safety.

1.1 Main Types of Material Handling Equipment & Their Applications

Material handling equipment is categorized into four main types based on their function:

1. Fixed Path Equipment (Conveyors & Pipelines)

• Conveyors: Used for continuous movement of materials in production lines and warehouses. Example: belt conveyors, roller conveyors.

• Pipelines: Used for transporting liquids, gases, and fine powders in industries like petroleum, chemicals, and food processing.

2. Mobile Equipment (Industrial Trucks & Vehicles)

• Forklifts: Used to lift and transport pallets in warehouses.

• Pallet Jacks: Manual or powered equipment for lifting and moving palletized loads.

• AGVs (Automated Guided Vehicles): Self-operating vehicles that move materials without human intervention.

3. Lifting Equipment (Cranes & Hoists)

• Cranes: Overhead, gantry, jib, and tower cranes used for lifting heavy loads in construction, shipyards, and manufacturing plants.

• Hoists: Used for lifting materials in workshops and factories, operated manually or electrically.

4. Storage & Retrieval Systems

• Racks & Shelves: Used for organized storage in warehouses.

• Automated Storage & Retrieval Systems (AS/RS): Computer-controlled systems for efficient material retrieval.

1.2 Types of Loads to be Handled

Material handling equipment is selected based on the type of load:

1. Unit Load: Individual items packed in boxes, pallets, or containers. Example: Electronics, auto parts.

2. Bulk Load: Loose materials like sand, coal, cement, grains.

3. Liquid Load: Transported in tanks, pipelines, or drums. Example: Oil, chemicals, beverages.

4. Gaseous Load: Transported in pressurized containers or pipelines. Example: Oxygen, LPG.

1.3 Types of Movements, Methods of Stacking, Loading & Unloading Systems

Types of Movements in Material Handling

1. Vertical Movement → Lifting and lowering materials (e.g., hoists, lifts).

2. Horizontal Movement → Moving materials along the same level (e.g., conveyors, trucks).

3. Inclined Movement → Moving materials at an angle (e.g., inclined conveyors, spiral chutes).

Methods of Stacking Materials

• Block Stacking: Placing materials on top of each other without support racks.

• Selective Racking: Using shelves for easy access to each item.

• Pallet Racking: Storing goods on pallets for organized stacking.

Loading & Unloading Systems

• Manual Handling: Labor-intensive, used for small loads.

• Mechanical Handling: Using conveyors, forklifts, and cranes for efficiency.

• Automated Systems: Robotics and AGVs for precise and fast material movement.

1.4 Principles of Material Handling Systems & Modern Trends

Principles of Material Handling

1. Planning Principle → Efficient layout and design for smooth material flow.

2. Automation Principle → Using automated systems to reduce labor dependency.

3. Safety Principle → Ensuring workplace safety by using proper equipment.

4. Standardization Principle → Using standardized containers, pallets, and racks.

5. Cost Reduction Principle → Minimizing handling time and energy consumption.

Modern Trends in Material Handling

1. Industry 4.0 & IoT Integration → Smart sensors and AI-based automation for real-time tracking.

2. Automated Guided Vehicles (AGVs) → Self-driving machines for logistics and warehousing.

3. Robotics in Warehousing → Robotic arms for picking, packing, and sorting items.

4. Drones for Inventory Management → Used in large warehouses for stock tracking.
