WG Series Pneumatic Winches (to 10,000 lbs)
A compact, lightweight air winch for hazardous or demanding environments: up to 10,000 lbs on a single line, or up to 152.1 FPM on the full drum. For new pneumatic installations we recommend the W2G or W2K Series, depending on the job.
For installed WG units we provide maintenance support and troubleshooting, replacement parts when available, and the technical documentation below. For new applications we recommend the W2G / W2K Series.
