Belt Storage

It is not uncommon for companies to stock spare belts so they can quickly replace a damaged belt on a critical conveyor. It is very important that these extra belts are stored correctly.

Here are some storage rules to follow to keep your belts in top condition.

Avoid belt camber (swing)

A belt that is placed horizontally on the ground for extended periods of time may warp under its own weight. After a few weeks, this deformation may permanently displace the carcass and create unwanted camber.

In addition, some carcass fabrics can absorb moisture. The rolls should therefore NEVER be stored on their edges! A belt stored vertically directly on damp ground will absorb moisture and shrink the exposed edge which will cause camber.

Ideally, the rolls should be suspended on a horizontal bar in a rack specially designed for this purpose. In addition, it is recommended to rotate each roll 90 degrees at regular intervals (2 months).

A belt with a camber greater than 1 inch per 100 feet in length will be impossible to align properly and will cause downtime, carryback and spillage.

Storage conditions

Ideally, the belts should be stored in a cool, dry building and in an area out of direct sunlight. If possible, keep them sealed in their original packaging to protect them from moisture, light and contamination. Avoid extreme temperatures and store them away from direct sources of heat such as boilers, radiators or direct sunlight.

If outdoor storage is unavoidable, the belts should be protected by tarp or other suitable material. Belts stored outdoors should be lifted off the ground to prevent damage from water, mud, sand, etc. Again, the ideal is to use a rack rather than pallets.

If the belts are stored at temperatures below 0 ° C, it is recommended that they be warmed for at least 24 hours at a temperature of 10 ° C before installation.
