The Requirement
The application for this unique lift table has to do with multiple conveyor lines moving large pallets of corrugated material though the system. The convergence of 3 conveyor lines that are at different elevations is challenging when moving loads from one line to another, as well as a discharge line.
The powered conveyor system being able to move up and down required making multiple tables welded into a large 9 ft x 15.5 ft with a “U”-shaped opening to work around an operator’s platform. The real challenge was not the design for that already existed with a previous supplied lift table. The issue was reliability. The lifts on one end could be loaded with a pallet load and empty on the other causing a strain on the various lifts resulting in breakdowns and excessive wear. These issues caused production delays and costly repairs.
The Solution
The solution by Lift Products was a double wide scissors assembly on one end with one of the scissors being double long. In addition, another scissor table was designed to be perpendicular to the double long and had to have a bolted-on assembly for shipping purposes. To have this all welded into one, and work in unison regardless of uneven loading, required Lift Products HBC system (hydraulic balance control system) using a 5 HP power unit. This system can allow one or more weighted pallets on any part of the lift table assemblies and not affect the empty tables performance or alignment.
This system provided the reliability and durability to keep production up at the expected pace.
