Manual vs Automatic Material Handling Equipment
Material handling equipment is a piece of machinery that allows you to move or lift materials from one place to another. You can find manual and automated material handling equipment in almost every industry. Both types of equipment come with distinct benefits and drawbacks of their own.
|Cheaper and easier to handle.|
|Consider ergonomic factors like repetitive motions and awkward positions.|
|Higher chances of accidents, hence risky.|
|Manual handling is prone to errors which may lead to frequent downtime.|
|It doesn’t require a large upfront investment, but can be expensive in the long run.|
|Expensive and trickier to handle as you need trained labor.|
|No need to consider these factors.|
|Considerably less prone to accidents and damaged goods.|
|Automation, on the other hand, increases efficiency.|
|Although it requires a substantial one-time investment, it’s relatively cost-effective in the long run.|
While many industries, especially in third-world countries, continue to use manual material handling equipment, automation is on the rise.
Objectives of Material Handling System (Reasons You Should Use It)
The industrial material handling process, like any other industrial process, requires a set of clear-cut objectives or goals. It allows you to use the system with the highest possible efficiency while keeping overheads down. Here are a few common objectives that you need to know about.
1) Cost Reduction
The primary objective of any material handling system is to reduce the cost of moving the load. The direct or indirect cost reduction often comes in the form of –
- Decreasing material handling labor.
- Optimizing the material handling labor depending on their level of skill.
- Reducing indirect labor for activities such as shipping, wrapping, traffic controlling, and inspection.
- Decreasing waste such as packaging materials and other protective devices such as racks and containers through optimization.
- Lowering the chances of potential damages to the load.
- Optimizing control requirements.
- Ensuring quicker through-put and limited in-process storage to streamline the manufacturing process.
However, being an auxiliary system in any manufacturing process, optimized material handling can also bring the overall production cost down by improving the flow of raw material.
2) Enhanced Capacity
A well-planned industrial lifting system also increases your capacity through better space utilization and improved warehousing and storage layout. For example, you can use high-altitude cranes along with specially designed racks or containers to make use of unused spaces such as the area high above production lines.
Alternatively, you can also improve the layout of the production line to reduce travel and excessive use of space. Optimizing the flow paths and the timing of material movement will allow you to increase your overall capacity further. It will also lead to better utilization of your labor.
3) Improved Productivity & Efficiency
The third objective of a material handling system is to improve overall productivity and efficiency. Using automated industrial lifting and material handling equipment reduces the loading, unloading, and transportation time for raw materials and finished goods within the facility. As the raw material sits on the docks or in storage for less time, there is no need for extra storage.
Further, the improved rate of raw material supply allows you to operate your equipment and labor at their fullest capacity. You can also optimize the number of loading and supervision crew. Thus, your overall productivity and efficiency can go up while keeping the labor costs down.
4) Improved Working Conditions
Handling heavy loads manually can be time-consuming, risky, and frustrating. Plus, you need to rely on a young and healthy workforce to move heavy loads, resulting in higher employee turnover and excessive need for training. All these factors also affect employee morale as the overall working conditions may seem too harsh.
However, you can use automated systems for lifting and handling material of any size, shape, and volume relatively comfortably. This, in turn, improves employee morale and the rate of output, resulting in higher productivity. Thus, material handling systems can improve working conditions significantly.
5) Reduced Waste
Material handling systems can reduce waste by improving the layout of your production plant. After a thorough analysis of the material volumes, flow paths between operations, and timing, you can make sure to reduce waste of time, space, and labor. Usually, you will need to rearrange equipment and provide the right handling systems to make this happen.
It will also allow you to decrease the waste of packaging material such as plastic wraps and cardboard boxes as well as storage material such as racks and specially designed containers. Reduced waste not only saves your money but also helps reduce environmental pollution.
6) Increased Safety
Manually lifting and handling material comes with a higher safety risk. According to the International Labor Organization (ILO), nearly 2.78 million workers die from occupational accidents and work-related diseases, and an additional 374 million workers suffer from non-fatal injuries every year.
Accidents can lead to fatal injuries, irrecoverable damages to the load, and costly downtime. However, an optimized material handling system can reduce the risk of accidents considerably, providing your employees with a safer workplace.
7) Improved Customer Service
Proper and improved materials handling systems often lead to higher efficiency, better speed, reduced production costs, and reliable and timely supply. All these factors, in turn, help improve your customer service significantly, especially in the B2B sector.
Categories of Material Handling Equipment
Material handling equipment is a broad term consisting of various elements such as tools (forklifts), vehicles (trucks), accessories (wire rope slings), and heavy appliances (overhead cranes). Usually, an industrial lifting system comprises more than one type of material handling equipment.
1) Storage and Handling Equipment:
Storage and handling equipment mostly consist of non-automated tools used to hold raw materials or finished goods. Using the right type of storage equipment helps increase space utilization and also streamlines the supply chain. Here are a few common types of storage equipment.
You can find different types of racks including:
- Drive-in racks where you can drive lift trucks between the uprights beams.
- Drive-through racks that are similar to drive-in racks, but they are open at both ends.
- Push-back racks provide gravity-based movement of the loads, allowing deep-reach storage without extended reach mechanisms.
- Sliding racks have sliding rows of racks along guide rails on the floor.
Other types of racks include pallet racks, carton-flow racks, flow through racks, single and double deep racks, and cantilever racks.
b) Bins and Drawers
Bins offer a low-cost alternative for storing small, loose, and lightweight items. Usually, you can place such items in the bin or a carton. Drawers also serve the same purpose but offer better security compared to bins. However, although low cost, neither is considered ideal for handling large load volumes.
c) Stacking Frames
These interlocking units allow you to stack the load to prevent it from crushing under the weight. You can assemble and dismantle the stacking frames as and when required to save the storage space. Pallet frames are often used for multilevel load stacking in warehouses.
Strong and stand-alone shelving systems are made from galvanized steel and welded steel and metal wires. You can quickly assemble these shelving units and adjust the size of the shelves as required. Boltless shelving units are often used as stand-alone or interconnected heavy-duty storage units.
Mezzanines are elevated floor systems often installed between the production floors and ceiling to obtain additional storage space. You can dismantle and move mezzanines whenever required.
2) Transport Equipment:
The transport equipment comprises various types of vehicles, particularly trucks, used for moving the load within or in and out of a facility. They can be manually operated or completely automated vehicles.
a) Industrial Trucks:
You can find a variety of industrial trucks ranging from simple l-shaped box-moving hand trucks and manual pallet jacks and forklifts to electrically powered order pickers, walkie stackers, and Automated Guided Vehicles or AGVs. Other examples include platform trucks, side loaders, personnel and burden carriers; turret trucks, counterbalanced lift trucks, as well as reach trucks.
Conveyors or conveyor belts usually allow you to move material along a fixed path and between specific points. You can find different types of conveyors depending on the type of load being handled, location, and the operating mechanism. There is a wide range of conveyors including chute conveyors, roller conveyors, chain conveyors, slat conveyors, bucket conveyors, pneumatic conveyors, and vertical conveyors among others.
Unlike conveyors, cranes are used to move loads across variable paths and distances. However, cranes have a lower rate of handling load volume compared to conveyor belts. The broad range of cranes primarily consists of jib cranes, overhead cranes, gantry cranes, and stacker cranes depending on their end use.
d) Lifts and Elevators
Industrial lifts and elevators are mostly used for vertical transportation. For example, you can use a freight elevator to move loads from one floor to another. Bucket and grain elevators are used for the same purpose. However, bucket elevators are meant to carry liquid or fluid loads while grain elevators often transport grains and similar materials.
3) Engineered Systems:
Engineering systems are mostly automated systems that work in tandem with other equipment for efficient storage and transportation of large volumes of loads.
a) Automated Guided Vehicles (AGVs)
Automated guided vehicles or AGVs are mobile robots that don’t require a human operator. They can travel along a predetermined path carrying low-to-medium volume loads across variable distances. They use infrared vision and laser technology for quick and safe movement.
b) Automated Storage and Retrieval Systems (AS/RS)
These are large automated systems with racks, shelves, a shuttle mechanism, and retrieval robots. There are various types of AR/RS systems including vertical lift modules, carousels, movable aisle, and fixed aisle systems.
c) Conveyor Systems
Conveyor systems often have an intricate network of more than one conveyor belts that can move large volumes of loads continuously.
d) Robotic Delivery Systems
These systems use automated robots to move variable loads across an assembly line or even within the plants. For example, picking up objects from a conveyor belt and putting it on another.
4) Bulk Material Handling Equipment:
This equipment allows you to handle material in bulk or lose form. They are used for both, vertical and horizontal transport of goods.
a) Stackers & Reclaimers
Stackers are automated or semi-automated tools that help you lift and stack heavy loads on the dock or the storage systems. Manual and powered walkie stackers and stacker cranes are also known as fork trucks on rails. Reclaimers perform the exact opposite function of recovering stored material from the stack. They are also powered or manually operated systems.
b) Hoppers & Silos
Hoppers are large containers with a tapering end with a small opening at the bottom. They hold materials like grains temporarily before discharging them into containers for packaging or further processing. Silos, on the other hand, are used to store grain and other materials such as coal, sawdust, woodchips, and food products.

Material Handling Equipment Challenges
Although material handling equipment offers plenty of benefits, it also comes with a few challenges of its own.
1) User Safety
User safety is a primary concern for business owners. According to a recent study, contact with moving machinery was responsible for 9% while getting struck by a moving vehicle and object lead to 31% fatal injuries.
Activities like handling, lifting, and moving were responsible for 21% of non-fatal workplace injuries while getting struck by a moving object lead to 10% of workplace accidents.
2) Inadequate Operating Knowledge
Currently, there is a lack of skilled and experienced workforce, making it difficult to provide a safe workplace environment. The lack of such workforce leads to higher labor costs, turnover rates, human errors, and downtime.
3) Human Error
Material handling is also grappling with the element of human error, which often leads to inaccuracies. This, in turn, may lead to fatal accidents, damaged goods, and production downtime.
4) Labor Costs
The shortage of skilled labor often leads to increased labor costs as the turnover rate goes up, increasing the cost of employee training further. At the same time, it creates an inefficient workforce that often fails to meet the desired production goals.
5) Downtime and Lower Productivity
Delays due to accidents or equipment malfunction can also cause substantial downtime. In a globalized world, even a short downtime can disrupt the entire supply management change leading to significant losses. Further, increased downtime means lowered productivity.
6) Material Management
Not having trained material handling labor means increased production line inefficiencies. These inefficiencies may cause you to run out of raw material or overstuff your product inventory. While interrupted raw material supply brings your production down, overstocking decrease your cash flow and results in additional expenses to store extra materials.
Factors to Consider When Choosing Material Handling Equipment
You can get the most out of your lifting and handling material equipment, provided you choose the right one.
1) Adaptability and Flexibility
Considering the sizeable cost of the equipment, it needs to be as adaptable and flexible as possible. You should be able to use it on more than one type of terrain, have several different moving and lifting mechanism, and handle more than one type of material.
2) Load Capacity
It should have enough load capacity to handle the desired load. If the machine exceeds the required load capacity, you will end up paying exorbitant fuel and labor costs. Under Capacity, on the other hand, will cause damage or even fatal accidents.
3) Type of Material to be Moved
The size, shape, weight, fragility, and type (solid, liquid, gas) of the load will also affect the choice of your equipment. For example, you can’t use wire rope slings for moving massive airplane parts; you will need chain slings for the job.
4) Speed and Power
The equipment also needs to have sufficient power and speed to move the desired load without causing any damage or accidents.
5) Site Layout
Space availability is also a critical factor in selecting material handling equipment. For example, low ceiling heights may prevent you from using overhead cranes, while pillar and columns might restrict the movement of large trucks or forklifts.
