Effortless Efficiency: The Role of Gravity Conveyors in the Modern Warehouse
by
By Scarlett Barnes
Gravity conveyors have had a long-standing presence in warehouse logistics, and for good reason. These easy-to-implement systems are not only affordable, but are also versatile across many different industries without the need for mechanical power. Starting in January 2025, SJF will be an official supplier of Roach Conveyors – one of the leading American-made manufacturers of gravity conveyors. This article will cover the basics of gravity conveyors – how they work, their application, and the benefits in hopes that it can help you determine if this is the right type of system for your company’s needs.
How Gravity Conveyors Work
A gravity conveyor is a non-powered material handling system that moves product using the natural force of gravity. Slope is key in the design and functionality of the overall system. Most systems are designed with a slight decline that is dependent on the product type, product weight, and system length. Flat systems can also be developed using a person pushing the material as the momentum to help the product slide down the line.
There are two main types of gravity conveyor styles: Roller and Skatewheel
Gravity roller conveyors use tube-like cylinders that rotate so that items can pass over them freely. They come in a wide variety of materials and diameters, making them customizable for anything from light to heavy duty items. To ensure proper support and movement, systems should be designed with a minimum of three rollers under the product at any given time.
Gravity skatewheel conveyors use individual wheels mounted on axels to allow smooth product movement. They can be designed with a variety of different materials, but are best suited for lightweight applications. To ensure proper support and movement, systems should be designed with a minimum of 10 wheels under the product at any given time.
Application
There are a variety of industries that can benefit from the implementation of gravity conveyors, including fulfillment centers, manufacturing, and even cold storage. These systems can handle a wide array of loads from light to heavy – especially if the items have a firm flat bottom, such as cartons, totes, cases, skids, drums, and more. Gravity conveyors are also flexible and adaptable for a multitude of uses, including production, distribution, shipping and receiving, as well as assembly lines. These conveyors can be installed with different specifications. Their sizes, lengths, widths, heights, and material can all be altered, as well as their method of mounting. They can be mounted on the floor, supported by stands, or even installed in rack systems. All of this together allows for complete customization, tailored to your company’s needs.
Benefits
Overall, gravity conveyors are a simple and cost-effective solution to warehouse logistics that can provide a number of benefits.
Minimal Investment: Since they rely on gravity there is no need for expensive motors or increased electricity usage. They are easy to install and operate, which keeps start-up and training costs low.
Efficiency: Gravity conveyors allow for a swift movement of product with minimal human intervention. This simplifies the workflow, reduces delays, and enhances productivity.
Maintenance: These systems are incredibly easy to maintain. Since there is no motor there is a low risk for mechanical breakdowns. They are made of simple parts that are durable (usually aluminum or steel), easy to clean, and easy to replace. If parts do break, replacements are typically accessible and made out of affordable material, rarely requiring professional service to fix.
Ergonomic Improvements: Employees also receive benefits from the advent of gravity conveyors. They reduce the need for manual lifting and carrying, which in turn reduces injury risk and worker fatigue. Overall, this makes for a safer work environment.
As the demand for efficient material handling solutions grows, adoption of gravity conveyors is expected to rise. These systems are an economical way to quickly optimize your warehouse logistics while providing a number of additional benefits to the overall operation. We at SJF see the potential these types of systems can provide for our clients and are excited to be working with Roach Conveyor to supply these high-quality products now and into the future.
