Optimize your Big Bag handling process by choosing the right Indus Neva product

When handling big bags, there are many challenges. Most of these challenges can be solved by using the Indus Neva.

When choosing an Indus product, sometimes it can be challenging to determine which version of the Indus Neva is most suitable. The different versions of the Indus Neva poles generally have the same functions. But, every case is different. In order to offer specific solutions, we have developed 3 different versions with unique properties: the lockhead, springhead and rolling springhead.

There are 2 important differences when choosing the right product: what is the big bag flow and whether narrow or wide big bags are used. We further explain these differences below:

What is the big bag process in your factory or warehouse?
There are roughly 3 situations to be distinguished when using big bags in the factory:

  1. Empty-Empty: In the first situation, empty big bags are filled and emptied on location afterwards. Here, we recommend using the (rolling) springhead. This system is designed to pull up the big bag when unloading. First, the big bag can be easily hung in the system and placed under a filling machine. The big bag stands stably on the deck during filling and is supported by the lifting loops attached to the poles to keep it upright. After filling, the big bag can then be transported or stored (stacked) until it is time to empty the material from the big bag into production. Emptying the big bag is simply done by placing the Indus Neva on a frame above your processing line, machine, container, or other equipment.
    Tip: Make sure that the discharge spout of the big bag is already put through the slide (before filling), the knot is opened, and the slide is closed. This ensures that when the slide is pulled open during emptying, the material starts flowing immediately (not recommended in food environments).
  2. Full-Empty: Filled/full big bags are delivered to your location, coming from an internal or external supplier. Big bags, ranging from 300-2000kg, are mostly supplied on a wooden pallet. The filled big bag needs to be placed in the Indus Neva directly when coming off the truck. After this, the proces of storing or emptying begins (see situation 1). Here, we recommend using the Lockhead. The (rolling) springhead, cannot be tensioned enough to be functional because the big bag is already filled.
  3. Empty-Full: In the last situation, big bags are filled internally and are not emptied but forwarded/transported to the next location of the customer/own company. Here, we recommend using the Lockhead. When a big bag is filled in the Indus Neva, the lifting loops are put under such tension that it is difficult to release this tension from the lifting loops and remove the big bag from the system again. This issue does not occur when using the Lockhead. The Lock can be easily moved up and down, allowing the lifting loop to be released.

The ideal situation: big bags are filled by the supplier within the Indus Neva, making it easy to transport the big bags, remove them from the truck and safely transport them to storage or production. In the production area, the big bags can be unloaded using the slide in the bottom deck.

Are narrow or wide big bags used?
Depending on the external bottom measurements of the big bag (width x length), we recommend different versions of the Indus Neva (based on a regular, non-stable-form big bag).

  • 93×93-100×100 – Advice: Lockhead or Springhead. These are the standard big bag sizes, and the Lockhead and Springhead are well suited for this purpose.
  • 85×85-92×92 – Advice: Rolling Springhead. Due to the pulley attached to the top of the spring head, narrower big bags can be placed in this system. The assisted emptying function works even better with the use of the pulley. Please note that the black pulley is facing inwards.

Note: For form-stable big bags, the bottom dimensions have a max. of 105×105 for the Lockhead and springhead because these big bags are positioned more tightly within the Indus Neva and are not bulking.

Measuring big bags
There are 2 options for measuring big bags:

  • Consult the specification sheet from the big bag manufacturer: In some cases, there is a specification sheet available for the big bag. This sheet often indicates the external dimensions of the big bag.
  • Measure the big bag: If no specification sheet is available, measure the empty big bag by stretching it out and measuring the bottom dimensions (width x length).
    • Length/Width: In many cases, a big bag is square, but it’s always best to measure both dimensions to be sure.
    • Height: Measure from the bottom to the top of the big bag, without including the lifting loop.
    • Lifting Loop: Measure the length of the lifting loop from the big bag to the highest point (without counting it twice).
