Wulftec WCRT-175 Automatic Stretch Wrapper

The Wulftec WCRT-175 conveyorized 3-legged stretch wrapping system keeps up with demanding production rates of lighter pallet loads.

Features of the WCRT-175

AC variable frequency drives as standard equipment on all machines
With lower maintenance and better reliability, Wulftec stretch wrappers will save time and money
NEMA 4/12 control panel dust tight and waterproof
Control panel is neatly organized eliminating time otherwise lost searching for wires
Control panel is UL508A approved
Superior electrical design including Allen Bradley MicroLogix PLC and AC drives
User-friendly touch-screen offers a simple 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
All Wulftec structures are made of heavy-duty steel for rugged performance, even in the harshest work environments
These stretch wrappers are built to last forever
Robust 3-legged design for optimal stability and less stress on the frame
25" ring gear with pinion gear drive provides the strongest drive in the industry and is warranteed for 10 years
Dual chain driven for balanced movement & no vibration
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 roller blue compound
Preset pre-stretch ratios are available from 50-300%
Angled carriage with very low wrap possibility properly secures the product to the pallet, resulting in stable transport and less damage
No film threading required
Lexan cover eliminates operator's ability to reach rollers when gate is closed
Wulftec's revolutionary drop away clamp ensures clean film release from the pallet load
Benefit from Wulftec's splash proof program with the top cover pause
Non-Proprietary parts accessible on a local base

Cut and Wipe System

Pneumatically operated cut and wipe-on system automatically cuts and wipes the film onto the load upon cycle end
First a vertical roller positions the film over the clamp which grabs the film, ensuring 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

Best Warranties in the Industry

3-year unlimited cycle warranty
10-year warranty on steel structure
10-year warranty on 25" ring gear bearings
Lifetime warranty on pre-stretch roller blue compound
