The Role of the Metal Cage
The metal cage of an IBC tote serves several functions necessary to the useability and security of the IBC. This includes:
- Support and Stability: The primary purpose of the metal cage is to provide support and stability to the plastic tank it holds. The plastic tank is flexible, and the metal frame prevents bulging and ensures that the tank will retain its shape. This is particularly important during transportation and when the tote is filled to capacity as the total weight of a full IBC container is significant.
- Damage Resistance: The metal cage provides a layer of protection to safeguard the inner plastic tank from potential damage that can occur during handling, vehicle transport, or worksite use.
- Stacking: The metal cage, along with the pallet base platform the inner tank sits on, allows for safe stacking of IBC totes, thereby improving organization and making IBCs an efficient solution to optimizing storage and space.
- Lifting and Moving: The frame and pallet design allow the tote to be easily lifted and moved using mechanical equipment such as forklifts. Such movement would not be possible with only the inner tank should the metal cage be removed.
Can IBC Totes Be Used Without the Metal Cage?
While some individuals have reported using IBC totes without their metal cages, this practice is generally not recommended. Without the cage, the tote may lack the necessary support and rigidity, especially when filled to full capacity or when handling materials heavier than water. This concern can increase with the number of times the IBC tote is filled and drained as it can weaken the plastic tank over time. Similarly, removing the tote’s cage can significantly compromise safety during transportation or stacking.
DIY hobbyists who report having used their poly cage totes without the cage many times build a custom frame, box, or structure to both house and support the tote.
Takeaway
IBC totes can function in storage without its metal cage; however, the cage plays a vital role in maintaining the tote’s stability, integrity, and safety, and thereby improving its reliability and service life. Therefore, in most circ*mstances, IBC totes should be used with their metal cages intact, especially for applications that involve heavy materials, hazardous cargo, or transportation.
