With their interlocking foot design, consistent dimensions, and dimensional stability over time, MacroBins offer significant improvements over wood bins in space utilization and room filling efficiency. MacroBins stack straight, reducing the space required between bins, and in many cases increasing storage volume significantly. Empty MacroBins can be stored outside, as they are molded using a state-of-the-art UV stabilization system. Recommendations for the safe storage of full or empty bins are as follows:
- MacroBins should always be stacked on hard level surfaces. When stacking more than four high, bins should only be stored in blocks of at least two stacks side by side. In general, the higher the stack, the wider the block. This will reduce the risk of bins being blown over by high winds.
- When MacroBins are stored more than four high, they should be located in an area away from personnel activity. Unauthorized individuals should be kept away from bin stacks.
- Care should be exercised when de-stacking non-vented MacroBins outdoors as the stack could be top heavy as a result of rainwater accumulation in the top bin.
- Because the 26 and 27 Series MacroBins are square and the stacking design is the same at each corner, it is possible to turn them 90 degrees when stacking on the bin below, but this must not be done. The corner posts are designed to transfer more of the weight to the side of the bin where the feet run the length of the bin and provide the necessary support.
Maximum Capacity and Stack Weight Limits
MacroBins have been designed to perform within specific maximum load capacities and stacking tolerances. For capacity and stack weight limits for MacroBins, please refer to Macro Plastics’ product specification sheets.
Fire Commodity Classification Ratings
For insurance purposes, call the Macro Plastics Technical Services Department for questions regarding Fire Commodity Classification Ratings. All MacroBins have a Commodity Classification Rating of Class III or better.
It is essential to ensure that load stresses are transferred in the designed manner in a stack of bins. To achieve this, MacroBins have been designed with a patented interlocking foot which ensures the proper bearing of loads: under no circumstances should MacroBins be interstacked with wood bins or other manufacturers’ plastic bins. Furthermore, the dimensions and interlocking systems differ between individual MacroBin models. MacroBin models can be interstacked with each other in the following groupings:
- 12 with 12 Series only
- 14 with 14 Series only
- 16 with 16 and 24 Series only
- 24 with 16 and 24 Series only
- 26 with 26 and 27 Series only
- 27 with 26 and 27 Series only
- 28 with 28 Series only
- 30 with 30, 32, 34 and 35 Series only
- 32 with 30, 32, 34 and 35 Series only
- 33 with 33 Series only
- 34 with 30, 32, 34 and 35 Series only
- 35 with 30, 32, 34 and 35 Series only
- 48 with 48 Series only
- 330 with 330 Series only
- T-Bin with T-Bin only
- DoubleShuttle with the DoubleShuttle only
Note: When interstacking bins of different heights, forklift opening heights will vary. Therefore, care must be taken when handling bins with double-wide forklifts.
MacroBins can be used over a wide range of temperature environments and filled with contents that fall within these ranges. MacroBins can be used within the following temperature ranges:
|HDPE||0º F (-17º C)||140º F (60º C)|
|PP||0º F (-17º C)||180º F (82º C)|
For applications below 0º F call the Macro Plastics Technical Services Department at 1-800-845-6555.
