Platform Lift

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.

Platform

Constructed from Type 304 stainless steel, the platform supports front or side loading and unloading. Each gate interlocks with the control system and secures with a manual locking mechanism to ensure operator safety. Depending on your facility design, the lift can operate with or without a recessed pit. This flexibility allows seamless integration into existing process areas.

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.

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.
