SERIES 3 TABLES
HOW THEY WORK
•
Each Lifting Column contains a mechanical lift mechanism that requires an external force to operate.
•
Lifting Columns and Gearboxes are connected to and mechanically synchronized with each other
through a telescoping Driveshaft assembly.
•
A hand-operated crank provides torque to operate the Lifting Columns.
•
Each Lifting Column contains internal stops that define the top and bottom of the range of motion.
•
Only one Crank Handle is used to drive the Lifting Columns, regardless of whether the Table has
two or three Lifting Columns.
•
The Crank Handle raises and lowers 2-leg Tables through a 4:1 ratio Gearbox.
•
The Crank Handle raises and lowers 3-leg (90º Corner) Tables through a 6:1 ratio Gearbox.
•
Certain small Tables have a Top-Crank Handle configuration; all other sizes have a Front-Crank Handle.
Refer to the Spec Guide for more information.
