motor-driven turntable / horizontal / for welding
There are two basic types of Floor Turntables provided by Koike Aronson Inc. / Ransome: A free standing "A" frame and free standing column design are used depending on size and capacity.
Machine capacities of 2,500 Lbs. and less utilize the "A" frame design. The "A" frame type turntable has a hollow spindle and uses pre-loaded tapered roller bearings. The bearing housing and main support "A" frame house the motor and gear reducer below the table, with no protrusions to prevent interference or damage to parts or equipment.
Machine capacities of 6,000 Lbs. and more utilize the free standing column design. The column design floor turntable uses a large diameter slew ring bearing and center column for supporting the load. Table deflection is reduced, while direct drive to the gear teeth on the bearing reduces maintenance.
All Koike Aronson Inc. / Ransome floor turntables are variable speed rotation using variable frequency inverter drives for smooth acceleration and deceleration control. Koike Aronson, Inc. / Ransome rotation axis are repeatable within ± 0.005 Inches per Inch of radius, with a consistent load, speed and direction.
