Description
The CDM Platform Lift is a sanitary post lift designed to safely move equipment and materials between floors in cleanroom environments. It offers multiple gate configurations, allowing flexible loading and unloading from any direction. Each system uses an Allen-Bradley control platform to deliver smooth motion, precise control, and reliable performance. Built to meet cGMP standards, the Platform Lift provides the safety, cleanliness, and dependability essential for pharmaceutical and high-purity processing.
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. All motors, gearboxes, and electrical enclosures remain fully enclosed within the footprint of the column. The lift maintains a clean exterior and minimizes exposure to the production environment.
Ball-Screw Driven
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. The system achieves smooth, accurate lifting under full load. The Ball-Screw drive configuration represents one of the safest and most efficient lifting technologies available.
Additionally, every 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. This design simplifies washdown and improves overall cleanliness in the production area.
Sanitary Platform
The platform is designed to the customer’s load and usable area requirements. Configurations allow up to three sides of access and can be installed with or without a pit. Constructed from 304 stainless steel, the platform is polished to a uniform finish, with all welds as laid, chemically cleaned, and passivated. All the platform gates are interlocked with lift movement, preventing operation when any gate is opened.
Optional – Maglock Integration
Maglocks can be incorporated into new or existing floor or mezzanine gates. These dual-channel, safety-rated maglocks are interlocked with the platform lift controls, allowing motion only when all gates are fully closed and locked. Gate status is displayed on the main operator panel, ensuring operator awareness and maintaining safe operation.
Operator Controls
Controls all equipment movements with automated sequencing and ‘Deadman’ control. Releasing the operator switch halts the sequence, forward or reverse may be selected at any position. At minimum, the following user interfaces will be provided: Power On/Off, Emergency Stop, Reset, Sequence Forward/Reverse.
Operator Panel Enclosure and Mounting
NEMA 4X Stainless Steel Enclosure. (*Other enclosure options available upon request.)
Operator Interface
6.5” Allen Bradley PanelView Plus 7 Touch Screen. (*Other interface options available upon request.)
Power Panel
High and low voltage panels. The panels house the PLC, VFDs, fuses, relays and power disconnect.
Power Panel Enclosure and Mounting
NEMA 4X Stainless Steel Enclosure. (*Enclosure type and location can vary based on room classification and customer requirements.)
Control Hardware
CompactLogix 5380 PLC and Allen Bradley PowerFlex 525 VFD(s). (*Other PLC and VFD options available upon request.)
UL 508A Certified Panel
Built and certified to UL 508A standards for compliance with industrial control standards
Stack Light with Audible Alarm
A stack light with an integrated audible alarm can be added to provide clear visual and sound-based status indication of lift operation, fault conditions, or safety interlocks. This enhances operator awareness and improves overall system visibility within the processing area.
Safety Light Curtain
A safety light curtain can be installed to create a non-contact protective barrier that prevents access to hazardous areas. If the beam field is interrupted during operation, the system will automatically stop motion to protect the operator from moving equipment.
Safety Laser Scanner
A floor-mounted safety laser scanner can be incorporated to provide three programmable safety zones, enabling warnings, controlled slow-down, or a full system emergency stop based on intrusion level. Multiple scanners can also be linked together to create a wider, continuous protective field around the lift.
