We’ve returned to the archives and uncovered some photos from past mezzanine projects Material Flow has done over the years:
Determining Frame Depth
The depth of the frame is determined by the size of the pallet. The most common pallet used is a 40″ wide x 48″ deep GMA wooden pallet. Using that as a guideline, the pallet should overhang the beams 3″ in the front and 3″ in the back thus making the frame depth 42″. The reason for this RMI rates beam capacities with 3″ front and back. When the operator is putting pallets away in the upper levels, it is wise to allow overhang so that the driver doesn’t inadvertently miss the beam when setting the pallet down.
Belts are used in both roller and slider bed conveyors.
- There are three general things that will determine the type of belt required:
1. Characteristics of the commodity to be handled.
2. Prevailing atmosphere conditions.
3. Operations to be performed.
Cantilever Rack is a freestanding storage unit with horizontal load carrying arms extending outward from a single vertical column. The absence of a vertical support on the outboard ends of the arms permits uninterrupted storage of long lengths of material.
The all roller and skatewheel type curves.
If boxes must remain oriented you should use a taper roller or a skatewheel curve section. If you use roller type curve sections, boxes should be spaced so the rollers are allowed to function properly. If boxes go through in a group or in a train, they more than likely will not stay oriented. The reason for this is that boxes behind are pushing those ahead of them.
The majority of a box or package must be on the curve section before it will turn properly. Long boxes can be a problem since they may not feel the effect of the curve until enough of the package moves onto the curve. If boxes are moving at a high rate of speed, they will not negotiate the curve properly.
In a gravity flow type system, it might be necessary to decline the curves. This is somewhat difficult since the curve must be twisted.
Material Flow & Conveyor Systems, Inc. carries and sells an excellent selection of conveyors!
