An Electric Hoist Makes Your Bulk Bag Unloader Safer
An electric hoist on your bulk bag unloader will benefit your workers in many ways. First and foremost is safety. You've probably heard some of the alarming statistics regarding fork truck safety. These representative statistics tell a concerning story.
- "(Injuries from forklift) accidents constitute 10% of all the physical injuries (in the workplace)"
- Forklift accidents that result in serious injury total 34,900 annually
- Non-serious injuries related to forklift accidents reach 61,800 each year
- A forklift overturning is the most common incident, accounting for 24% of all forklift accidents
Some industries and manufacturing environments are best suited for fork trucks. Others, like food and pharma, often seek alternatives to accommodate hygiene and small space requirements.
Good training is essential, and many fork trucks operate safely. However, 11 percent of the 855,000 forklifts in the U.S. will be involved in an accident. So when there are reasonable alternatives, it's worth considering.
An electric hoist is a safe alternative to fork trucks for bulk bag unloaders (also known as super sack discharger). Not only does an electric hoist eliminate the need to have a fork truck lift a 2,000-pound bulk bag 10 to 12 feet into the air, it also provides additional operational and financial benefits.
Bulk Bag Unloaders Reduce Labor Cost and Boost Efficiency
To load a bulk bag discharger with a forklift as safely as possible requires two workers. One drives the forklift and hoists the bag. The other climbs up on the unloader and secures the bag to the suspension frame.
Visualizing that process, one operator has their vision restricted by the pallet on the forks and advances into the frame where their colleague is standing. That colleague isn't working from a stable mezzanine but has climbed to reach the connection point and is working over an open area while making the connection.
It takes time for two workers. It takes alertness and patience. In a noisy environment, it's hard to hear spoken instructions.
Adding an electric hoist to a bulk bag unloader, however, changes the game.
With an electric hoist, a pallet jack can be used to move the bulk bag into position in front of the unloading system. The hoist is mounted on a gantry and operated via a control lanyard. This allows the operator to stand clear of the bag. That keeps them clear of the hoist and frame, but more importantly keeps everyone clear of the danger zone as the FIBC is being raised and moved into position. The risk of workers inadvertently entering the area below a suspended 2.000-pound bag is important to avoid.
Once the hoist is lowered, the operator connects each of the four corners with lifting loops. If you are comparing bulk bag unloaders, be sure to look for a model that includes the redundant safety clips which ensure the loops don't slip off the lifting frame.

Electric Hoists Aid Bag Stretching
A bulk bag unloader should unload consistently and fully. While it may help to add vibration and bag massagers (both offered with AZO's Modular System with short lead-times) often the bag has to be stretched as it empties so the product is fully unloaded.
If using a fork-truck for bulk bag unloading, consider a few things regarding bag stretching.
First, it probably won't happen. As a result, some of your savings from bulk material purchase will be lost and wasted as it's discarded with a bag that hasn't been fully emptied.
Second, It will take two operators to maximize safety. Even if it's one, it will be cumbersome and time consuming to follow all required fork-truck safety procedures and stretch the bag.
Third, it takes time, and very few facilities have workers with any extra.
An electric hoist, in contrast, allows a single operator to easily stretch the bag conveniently with the lanyard controls from the safety of the floor away from the unloading zone.
Looking at Bulk Unloading Holistically
There are more than 60 bulk material handling equipment vendors in the U.S. That's great for buyers considering a wide range of options for their manufacturing challenges — from material receipt, through transfer, conditioning, conveying, to blending, mixing and bulk packaging.
With so many options, how do you spec the right solution and select the right vendor?
Focus on safety, durability and operational efficiency. Don't think of it as buying steel (some vendors will tout how much their lines weigh!) - rather think about the material flowing in one end of your building and finished product out the other.
You’ll need a bag dump station. Maybe an electric hoist and trolley with good lift speed. You may possibly need some dosing and feeding components, processing equipment and a receiving hopper. Dust collection is often an integral bulk bag unloading feature. The bottom line: no two bulk bag fillers are the same.
