Hygiene is decisive
In food production, equipment must not accumulate dust, dirt or moisture — and if it does, it must be easy to clean. This affects the crane's surface finish, paint system, and even structural details such as pockets that trap water or inaccessible corners.
In wash-down areas, the ingress protection rating of the motor, panel and junction boxes is raised; in some applications stainless steel or specially coated components are used.
Managing oil and grease
The crane's lubrication points must not sit directly above the production line. Where this can't be avoided, drip trays or sealed lubrication solutions are used. In areas with a risk of food contact, food-grade lubricants are preferred.
Typical solutions
| Condition | Solution |
|---|---|
| Wash-down area | Elevated IP rating, suitable surface and paint system |
| Direct food contact risk | Stainless steel component, food-grade lubricant |
| Fixed-route transport | Monorail line — compact and easy to clean |
| Packaging line feeding | Jib crane or a light lifting system |
| Cold storage | Grease and components suited to low temperature |
| Hygiene inspection | Cleanable surfaces, accessible maintenance points |
Frequently asked questions
Does the whole crane have to be stainless steel?
Usually not. What matters is whether the crane is in an area with food contact risk. In most facilities, a suitable paint system and an elevated protection rating are enough.
Does a crane work in a cold store?
Yes, with the right grease, materials and electrical components. If the temperature range isn't specified up front, standard components can fail at low temperatures.
