The Will-Burt Pneumatic Heavy-Duty Non-locking (HDNL) and Super Heavy-Duty Non-locking (SHDNL) Masts offer a light-weight solution with a high payload lifting capacity. Our Pneumatic Non-locking Masts also feature a high pointing accuracy and long mast life for high performance and dependability. The pneumatic heavy-duty design makes it inherently safe – the payload sits on a “cushion of air” enabling it to better absorb shocks. What’s more, the Pneumatic Nonlocking Masts have controlled exhausting of air to prevent crashing. Locking models are available for extended deployments.

The line of pneumatic non-locking telescoping masts are ideal for communications and surveillance applications. These masts are free-standing vehicle-mounted units so no additional guylines are needed. All pneumatic masts can be either vehicle or trailer mounted. Super heavy-duty models feature greater heights and larger payload capacities.

• Maintains azimuth - minimal twist deflection reliable full-length external keyways
• Operates in extreme environments - external wipers protect against sand and dust
• Low maintenance and life-cycle costs easy to operate and maintain low friction synthetic bearings
• Long life - black hardcoat protects against salt fog corrosion
