The PUA664 floor scale allows quick and easy cleaning in general weighing applications. Lifting the front handles tilts the entire scale up to provide complete access for cleaning the floor and underside of the scale. A pair of built-in gas springs enable one person to lift the scale manually with minimal effort. No cranes or other lifting devices are needed. There is no pit to clean out and no need to recalibrate the scale after cleaning. The convenient lift-deck design is ideal for applications where space is limited. Install the scale next to a wall so that it can be lifted out of the way when not in use. When the scale is needed, a single person can lower it into weighing position in seconds.

Cleaning Applications

The PUA664 floor scale meets the needs of batching, filling, and other applications that require frequent cleaning under and around the scale. It is designed to handle the weighing and cleaning requirements of chemical and general industries.

Safety Locks

Engaging a pair of safety locks prevents the scale from moving when it is in either the up or down position. The scale platform is securely attached to the frame so that it remains in place when raising and lowering the scale.

Rocker Pins

Each load cell has a rocker-pin suspension that automatically aligns load forces for accurate and repeatable weighing. This type of suspension provides better performance and is more durable than threaded feet.

Optional Ramps

Ramps are available to provide easy access from the front and back of the low-profile scale. They eliminate the need to lift heavy loads, allowing them to be wheeled onto the scale platform safely and easily.
