What is Material Handling Equipment?
Definition
Material Handling Equipment (MHE) refers to the machinery, tools, and systems used in the movement, storage, control, protection, and processing of materials. These devices are designed to facilitate the efficient handling of goods throughout various stages of production, distribution, and supply chain management.
Key Characteristics
- Purpose: MHE is primarily focused on moving and storing materials efficiently.
- Types: Includes forklifts, conveyors, cranes, hoists, pallet jacks, automated guided vehicles (AGVs), and storage systems like shelving and racking.
- Automation: Many modern MHE systems are highly automated to improve speed, accuracy, and safety.
- Integration: Often integrated with warehouse management systems (WMS) and enterprise resource planning (ERP) software for seamless operation.
History
The concept of material handling dates back to ancient times when humans used simple tools like levers and pulleys to move heavy objects. The industrial revolution in the 18th and 19th centuries introduced more advanced machinery, such as cranes and conveyor belts, which laid the foundation for modern MHE. In the 20th century, the development of powered equipment like forklifts and AGVs marked significant advancements in the field.
Importance
MHE is essential for optimizing supply chain operations, reducing manual labor, and improving productivity. Efficient material handling ensures that goods are moved safely and quickly, minimizing the risk of damage and downtime. It also plays a critical role in supporting lean manufacturing practices by streamlining workflows and reducing waste.
What is Maintenance Repair and Operations (MRO)?
Definition
Maintenance Repair and Operations (MRO) refers to the activities and processes involved in maintaining, repairing, and operating equipment, facilities, and systems to ensure their continued functionality. MRO encompasses both routine maintenance tasks and emergency repairs aimed at keeping operations running smoothly.
Key Characteristics
- Scope: MRO covers a wide range of activities, including preventive maintenance, corrective maintenance, predictive maintenance, and operational support.
- Types of Work: Includes tasks such as equipment inspections, lubrication, part replacements, calibration, and system upgrades.
- Tools and Materials: Involves the use of tools, spare parts, lubricants, and other consumables required for maintaining equipment.
- Strategic Importance: MRO is critical for minimizing downtime, extending asset lifespan, and ensuring compliance with safety standards.
History
The concept of maintenance repair and operations has evolved alongside industrialization. Early maintenance practices were reactive, focusing on fixing equipment only after it failed. Over time, organizations adopted preventive maintenance strategies to reduce unplanned downtime. The introduction of computerized maintenance management systems (CMMS) in the latter half of the 20th century further revolutionized MRO by enabling better planning and tracking of maintenance activities.
Importance
MRO is vital for maintaining operational efficiency, reducing costs associated with equipment failures, and ensuring compliance with safety and environmental regulations. Effective MRO strategies help organizations achieve higher levels of productivity while extending the lifespan of their assets.
Key Differences
-
Primary Focus
- Material Handling Equipment (MHE): Focused on moving, storing, and controlling materials.
- Maintenance Repair and Operations (MRO): Focused on maintaining, repairing, and operating equipment and facilities.
-
Scope of Application
- MHE: Primarily used in logistics, warehousing, manufacturing, and supply chain management.
- MRO: Applicable across all industries where equipment and systems require ongoing maintenance and repair.
-
Tangible vs. Intangible Aspects
- MHE: Involves physical machinery and tools (tangible assets).
- MRO: Encompasses processes, activities, and strategies (intangible aspects).
-
Involvement in Production Processes
- MHE: Directly involved in the movement of materials within production or distribution processes.
- MRO: Indirectly supports production by ensuring that equipment remains operational.
-
Organizational Hierarchy
- MHE: Typically falls under the purview of logistics, supply chain, or warehouse management teams.
- MRO: Usually managed by maintenance departments or facilities management teams.
Use Cases
When to Use Material Handling Equipment
- Warehousing and Distribution: Forklifts and conveyors are essential for efficiently moving goods within a warehouse.
- Manufacturing: Automated guided vehicles (AGVs) are used to transport raw materials and finished products within assembly lines.
- Supply Chain Management: Cranes and hoists play a critical role in loading and unloading shipments at ports and terminals.
When to Use Maintenance Repair and Operations
- Equipment Maintenance: Regular inspections and part replacements for machinery in manufacturing plants.
- Facility Management: Routine checks on HVAC systems, electrical infrastructure, and plumbing to ensure smooth operations.
- Emergency Repairs: Quick fixes to equipment that has broken down to minimize production downtime.
Advantages
Material Handling Equipment (MHE)
- Efficiency: Reduces manual labor and speeds up the movement of materials.
- Safety: Minimizes the risk of workplace injuries associated with lifting heavy objects.
- Space Utilization: Advanced MHE systems like automated storage and retrieval systems (AS/RS) optimize warehouse space.
Maintenance Repair and Operations (MRO)
- Cost Savings: Preventive maintenance reduces the likelihood of costly equipment failures.
- Productivity: Ensures that machinery remains operational, avoiding production delays.
- Compliance: Helps organizations meet safety and environmental regulations by maintaining equipment properly.
Disadvantages
Material Handling Equipment (MHE)
- High Initial Investment: The cost of purchasing advanced MHE systems can be prohibitive for small businesses.
- Maintenance Requirements: Requires regular upkeep to ensure proper functioning, adding to operational costs.
- Training Needs: Operators need specialized training to use complex machinery effectively.
Maintenance Repair and Operations (MRO)
- Resource Intensive: Requires skilled personnel, tools, and spare parts to perform maintenance tasks.
- Complexity: Managing an effective MRO program can be challenging due to the variety of equipment and systems involved.
- Ongoing Costs: Maintenance activities involve recurring expenses for consumables and labor.
Popular Examples
Material Handling Equipment (MHE)
- Forklifts: Used in warehouses and distribution centers for lifting and transporting pallets.
- Conveyor Systems: Employed in manufacturing facilities to move materials along assembly lines.

Conclusion
Material Handling Equipment (MHE) and Maintenance Repair and Operations (MRO) are two distinct but equally important aspects of modern operations management. While MHE focuses on the physical movement and storage of materials, MRO is concerned with maintaining and repairing equipment to ensure uninterrupted operations.
Choosing between the two depends on the specific needs of an organization. If the goal is to improve logistics efficiency and reduce manual labor, investing in MHE is essential. On the other hand, if the priority is to keep machinery running smoothly and minimize downtime, a robust MRO strategy should be implemented.
Ultimately, a well-rounded operations management approach will integrate both MHE and MRO to achieve optimal performance, cost savings, and compliance with industry standards.
