Will-Burt’s Ultra Heavy-Duty Pneumatic Mast provides height and payload capacity scalable to meet specific requirements.
Pneumatic Ultra Heavy-Duty (Locking) Non-Military Mast
Engineered for Mobile Communications
The Ultra Heavy-Duty is a telescoping pneumatic mast constructed of weather-resistant anodized aluminum with easy-to-operate and rugged positive locking pins for safe, long-term deployment without air pressure. Compared to hydraulic steel masts, it delivers higher lifting capacity at a lower weight of 880 pounds (399 kg). The Ultra Heavy-Duty Mast does not require hydraulic fluid for elevation thus eliminating the potential for environmentally hazardous leaks. The strength of the Ultra Heavy-Duty Mast delivers significant unguyed performance, providing easier antenna deployment in paved parking lots and urban areas.
The Ultra Heavy-Duty Mast offers a total payload lifting capacity of 1,200 pounds (544 kg) at 59 feet (18m). The top tube of the mast can deploy payloads up to 1,000 pounds (453 kg) and another 200 pounds (91 kg) can be deployed from intermediate tubes. The nested height of 11.3 feet (3.4 m) eliminates the need for a tilt system, delivering cost savings, reducing complexity and allowing for more payload capacity on a COW or COLT.
The Ultra Heavy-Duty pneumatic mast was designed to meet the evolving requirements of mobile communications:
