The total time required for the movement of material is sum of the actual move time and time taken in loading, unloading and other allied activities which do not involve the actual transport of materials.
They provide more flexibility in movement than conveyors and cranes because there are no restrictions on the area covered, and they provide vertical movement if the truck has lifting capabilities.
Work and working conditions should be adapted to support the abilities of a worker, reduce repetitive and strenuous manual labor, and emphasize safety. All material handling methods, equipment, controls and software should be standardized and able to perform a range of tasks in a variety of operating conditions.
Materials handling notes pallet racks Vertical carousel Storage equipment is used for holding or buffering materials over a period of time. Hence, sufficient attention must be given in fitting the internal transport system in the manufacturing plant so as to constitute a single unit.
Positioning equipment[ edit ] Positioning equipment is used to handle material at a single location. The high cost of using an industrial truck for material transport is due to both the labor costs of the operator and the negative impact on the performance of a production system e.
This factor will ultimately improve satisfaction and safety level of workers. It can expose workers to physical conditions that can lead to injuries that represent a large percentage of the over half a million cases of musculoskeletal disorders reported in the U. Most cranes utilize trolley-and-tracks for horizontal movement and hoists for vertical movement, although manipulators can be used if precise positioning of the load is required.
Handling of materials is an integral part of the production process. Energy use and potential environmental impact should be considered when designing the system, with reusability and recycling processes implemented when possible, as well as safe practices established for handling hazardous materials.
Material movement and storage should be coordinated throughout all processes, from receiving, inspection, storage, production, assembly, packaging, unitizing and order selection, to shipping, transportation and the handling of returns. Using the exact conditions of the lift height, distance lifted, weight, position of weight relative to body, asymmetrical lifts, and objects that are difficult to graspsix multipliers are used to reduce the maximum recommended weight for less than ideal lifting tasks.
The materials and typically carried on a pallet for convenience in handling. Usually a large part of indirect labour is engaged in material handling.
Employ mechanical aids in place of manual labour in order to speed up material movement, increase the efficiency and economy of the system where possible.
Cranes provide more flexibility in movement than conveyors because the loads handled can be more varied with respect to their shape and weight.
Different types of industrial trucks can be characterized by whether or not they have forks for handling pallets, provide powered or require manual lifting and travel capabilities, allow the operator to ride on the truck or require that the operator walk with the truck during travel, provide load stacking capability, and whether or not they can operate in narrow aisles.
Examples of bulk-handling conveyors include the magnetic-belt, troughed-belt, bucket, and screw conveyors. Material handling processes should be simplified by reducing, combining, shortening or eliminating unnecessary movement that will impede productivity.
Unit load formation equipment[ edit ] Four-way pallet Unit load formation equipment is used to restrict materials so that they maintain their integrity when handled a single load during transport and for storage.
If materials are self-restraining e. Automated guided vehicles AGVs are industrial trucks that can transport loads without requiring a human operator.
A material handlings equipment is not considered production machinery.A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials.
They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight /5(15).

Starting from the time the raw materials enter the factory gate and goes out of the factory gate in the shape of finished product, it is handled at so many stages, so material handling is the integral part of the manufacturing process.
As the materials must be turned, moved and positioned on the. Lecture Notes Course Home Syllabus set up of material handling system, capacity sizing. Design of Manufacturing System. Queuing for System Design.
