Technical Information
  • The machine is provided with a manual including electro/mechanical schematics and drawings, maintenance program and PLC program disk
  • Wulftec was the first in North America to put AC variable frequency drives as standard equipment on all machines. Why? Lower maintenance and better reliability—Wulftec stretch wrappers will save time and money
  • NEMA 4/12 control panel dust tight and waterproof
  • The control panel is neatly organized eliminating time otherwise lost searching for wires
  • The control panel is UL508A approved
  • Superior Electrical/Electronic Design including Allen Bradley MicroLogix PLC and AC drives
  • User friendly touch screen offers a simple yet effective way to adjust and maintain your equipment
  • All motors, proximity sensors, photoeyes and other sensors have quick disconnect cables that simplify installation and maintenance

Product Description

The WCA-SMART™ a competitively-priced extra heavy duty ring-gear driven conveyorized turntable stretch wrapping system.

Our Automatic stretch wrappers maximize throughput and efficiency. They take care of everything; you only change the roll of film. An automatic stretch wrapper will save significant time and money.

Turntable stretch wrappers are ideal for wrapping stable loads of under 8,000 lbs.  They are typically less expensive than rotary arm models and have a smaller footprint – a definite asset when space is at a premium.
