Wulftec WCRT-200

Automatic Rotary Arm Stretch Wrapper

The WCRT-200 conveyorized fully automatic rotary arm high-speed stretch wrapping system.

Automatic Rotary Arm Stretch Wrappers maximize throughput and efficiency. An automatic stretch wrapper will save critical time and money.

The WCRT-200 is ideal for wrapping very light, very heavy, tall or unstable loads and great in wash-down and dusty applications.

Features

  • AC variable frequency drives as standard equipment
  • 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
  • Heavy-duty steel for rugged performance, even in the harshest work environments. They’re built to last forever
  • 4-legged design for maximum stability at high speed
  • A 25" ring gear with pinion gear drive provides the strongest drive in the industry
  • Dual chain driven for balanced movement & no vibration
  • Our heavy duty conveyors are second to none in the industry
  • The "Maintenance Free" spring loaded carriage gate equipped with spring loaded rollers, ensures optimal contact with the stretch film year after year, without involving maintenance
  • Wulftec is the only manufacturer to offer a LIFETIME warranty on its pre-stretch rollers’ blue compound.
  • Preset pre-stretch ratios are available from 50-300%
  • The angled carriage with very low wrap possibility, the product is properly secured to the pallet, resulting in a pallet that is more stable for transport, and therefore less damage
  • No film threading is required and a Lexan cover eliminates operator's ability to reach rollers when gate is closed
  • The pneumatically operated cut and wipe-on system automatically cuts and wipes the film onto the load upon cycle end
  • A vertical roller positions the film over the clamp which grabs the film; this ensures longer heat wire life expectancy
  • Then the heat wire swings in and cuts the film
  • A timed impulse heat control, allows quick cool down so the heat wire becomes cold to the touch within 5 seconds
  • Wulftec's revolutionary drop away clamp ensures clean film release from the pallet load
  • Non-Proprietary parts accessible on a local base
