FIBC Lift

Description

The FIBC Lift by CDM is a sanitary post lift engineered to safely raise bulk bags and Super Sacks for efficient discharge into downstream equipment. It minimizes dust and ensures smooth, precise operation in cleanroom environments. Each lifting arm is custom-designed to match the specific bag dimensions for a secure fit. Featuring an Allen-Bradley control system, the lift delivers reliable performance and accurate monitoring. Built to meet cGMP standards, it provides outstanding safety, cleanliness, and efficiency for powder processing applications.

Bag Handling

Each lift includes a custom Bag Lifting Arm designed to engage the standard lifting loops of bulk bags quickly and safely. Once secured, the arm raises the bag and rotates smoothly over downstream equipment for discharge. After material transfer, the lift automatically returns to the load position, ready for the next cycle. As a result, this process improves workflow, reduces operator handling, and maintains consistent product containment.

Lifting Column

The column is built from 304 stainless steel and polished to a uniform brushed finish. All external welds are ground smooth to match the parent material. In addition, the motors, gearboxes, and electrical enclosures remain fully enclosed within the column. Therefore, the lift maintains a clean exterior and minimizes exposure to the production environment. As a result, operators benefit from both easy maintenance and long-term reliability.

Slue / Rotation

A TEFC electric gearmotor powers the column rotation, located conveniently at the rear base beneath a stainless steel cover. The design allows over 270° of smooth, programmable rotation. Consequently, operators can easily set custom slue angles to match their process layout. Moreover, the rotation settings can be adjusted in the field to meet specific production needs.

Ball Screw Driven Lift

A precision ball screw drive couples directly to an electric gearmotor with a fail-safe brake. The screw and nut feature matching helical grooves where lubricated ball bearings circulate continuously for efficient motion. Therefore, the system achieves smooth, accurate lifting under full load. Furthermore, this configuration represents one of the safest and most efficient lifting technologies available. The lift motor sits at the base of the column for easy access, while height and travel parameters can be quickly field-programmed.

Every CDM lift includes a Safety Ball Nut Clutch. This direct-engagement clutch is mounted to the lift drive ball nut and releases automatically if the carriage lowers onto an obstruction. As a result, the clutch prevents component damage and enhances operator safety. Reversing direction automatically reengages the drive for immediate recovery.

cGMP Slot Cover

The front slot of the column features CDM’s patent-pending magnetic “Positive Seal Closure.” This two-part magnetic strip forms a watertight seal that moves with the carriage. In this way, the seal continuously closes behind it as the lift travels, reducing the chance of contamination. Moreover, this design simplifies washdown and improves overall cleanliness in the production area.

Controls

The control system uses an Allen-Bradley PLC platform for dependable, repeatable performance. Operator and Power Panels are enclosed in NEMA 4X stainless housings suitable for washdown and cleanroom use. Additionally, the system can include either push-button or touchscreen interfaces depending on user preference and process needs. Moreover, data logging, safety interlocks, and system feedback ensure precise control throughout the lift’s operation. In conclusion, this control package provides exceptional flexibility and reliability for regulated environments.
