Gravity Roller Conveyor Systems

Gravity Conveyors

An important value of a gravity conveyor is moving items without power.
Gravity conveyor systems are two types of gravity conveyors: gravity wheel and gravity roller conveyors.

We bet you have heard about other types, such as gravity feed conveyors, gravity spiral conveyors, gravity pallet conveyors, flexible gravity conveyors, and even heavy-duty gravity. What should you keep in mind?

Talking about the technical side, wheel, roller, and flexible variations present a big family of conveyors.

Rail wheel conveyors

Rail wheel conveyors are commonly floor- or rack-mounted to convey unit loads utilizing two or more parallel rail conveyors. Rail-wheel conveyors are lightweight. There are some models of rail wheel conveyors. They vary in weight, number of wheels per foot, and maximum frame capacity. For instance, model RCD rail wheel conveyors are available in two popular styles. Model RCD-3 features wheels in a 3” pattern, while model RCD-1.5 includes a 1-1/2” staggered dense wheel pattern.

Gravity skate wheel conveyors

Gravity skate wheel conveyors are designed for two big applications: straight and curved sections. Frames: formed galvanized steel channel 2-1/2” x 1” x 12 ga. Frame capacity: galvanized steel 350 lbs. max. distributed live load per 10’ section, or 1300 lbs. per 5’ section. The curves are 4’ or 5’ outside radius.
Please note that different manufacturers indicate different numbers of wheels that should be placed under the product. This depends on the total width of the conveyor and the model. A gravity flow skate wheel conveyor is used to move light loads with smooth flat bottoms, such as cartons and plastic boxes, crates, sheets, etc.

You can view the following items here:

Galvanized Gravity Roller Conveyor Straight Sections for light-duty applications.
Galvanized Gravity Roller Conveyor Straight Sections for medium-duty applications.
Galvanized Gravity Roller Conveyor Curved Sections for light-duty applications.
Galvanized Gravity Roller Conveyor Curved Sections for medium-duty applications.

Gravity roller conveyors

Gravity roller conveyors are used to move loads with an uneven bottom. Thus, items should never be longer than the length of the rollers. Notice that the conveyor’s total width includes the frame’s width, which is one inch on either side of the rails. So, if your package requires 16 inches, the gravity roller conveyor width should be at least 18 inches.
There are various models of straight and curved gravity roller conveyors. Curves with a 4′-0″ inside radius are manufactured in 45-degree sections and require full support at the center of the curve.

There are also two types of curved gravity roller conveyors: single and double roller curves. Gravity conveyor roller capacity is available from 250 to 540 lbs. per roller.
For straight sections of a steel gravity roller conveyor, roller capacity can be 700 and 2500 lbs. per roller, depending on the model. This allows them to be used for the transportation of pallets. However, be careful while utilizing the conveyor 24/7/365 as the equipment can malfunction.
Gravity roller conveyor systems exist in some variations: light-duty gravity roller conveyors, medium-duty, and heavy-duty gravity roller conveyors. This depends on the standard roller sizes and loads. Larger rollers can support more weight, but they are more expensive.

Gravity-feed conveyors

Gravity-feed conveyors support transferring materials onto another type of conveyor or equipment. Typically, a gravity feed roller conveyor is used to automatically feed products into an assembly system. The times when feed conveyors were only talked about in the case of raw material feeding are gone. Now you can use them to assemble items up to a certain level and then push them to the surface of the next equipment, such as a gravity belt conveyor, to eliminate labor.

Gravity Roller Applications and Cases

In this section, we’ll explore the real-world applications and success stories of using gravity rollers to effortlessly transport goods, leaving businesses rolling in profits. Gravity roller conveyors are a popular choice for assembly lines and distribution centers due to their efficiency in transporting products without the need for external power sources. Here are some examples of how companies have utilized gravity rollers:

1. A well-known e-commerce giant found that incorporating gravity roller conveyors into their order fulfillment processes allowed them to move parcels quickly and efficiently from one area to another without relying on manpower alone. This led to an increase in productivity, as well as a decrease in labor costs.
2. A leading automotive manufacturer implemented a gravity roller conveyor system on their assembly line, resulting in streamlined production processes and fewer delays caused by manual transportation of parts.
3. An international clothing retailer installed a gravity roller conveyor system throughout their distribution center, allowing them to process orders faster with fewer errors while also reducing their carbon footprint by eliminating the need for powered equipment.
4. A small-scale bakery incorporated gravity rollers into their packaging line, which helped them move baked goods from one station to another with ease while minimizing product damage.

Overall, incorporating gravity rollers into your business can lead to increased efficiency and productivity while reducing labor costs and environmental impact. With so many successful case studies available, it’s clear that businesses across various industries can benefit from implementing this technology in their operations.
