An aluminum mast that can expand and contract through the injection and discharge of air. It allows for easy elevation and lowering of cameras, antennas, lighting equipment, observation instruments, and more to high places.
The air-operated telescopic mast is an aluminum mast that can be extended and retracted by injecting and releasing air. The mast is made of lightweight aluminum alloy tubes that have been anodized, making them resistant to corrosion and highly durable. The number of sections can vary from 2 to 14, depending on the height when extended or retracted and other specifications. Models with a locking mechanism on each section can be locked at each section or in between sections, allowing the mast to be fixed at the desired height, which will be maintained even after releasing the air. Smaller models can be extended using a manual pump, so no power supply is required. By opening the air release valve and letting the air out, the mast will slowly descend (retract) under its own weight. Therefore, no power supply is needed for retraction in emergencies, and it can be retracted even during a power outage. Since there are no mechanisms or mechanical parts such as motors, wires, or pulleys, there are no troubles caused by failures of these components, and special maintenance is not required. It is safe because even if the air hose disconnects, it will slowly descend under its own weight.

basic information
■ A telescopic mast that extends by sending air into a multi-segment aluminum tube and contracts by releasing air. ■ The compact type can be extended using a manual pump and does not require power. The large type uses an air compressor. ■ Replacing and maintaining antennas, lighting, and various equipment mounted on the mast top can be done safely and efficiently without the need for high-altitude work by contracting the mast. ■ During strong winds such as typhoons, contracting the mast can minimize damage to mounted equipment. ■ Even if the air hose disconnects, the structure prevents rapid descent, allowing for a slow and safe lowering. ■ There are no mechanical parts, so there are no issues with rising or descending due to malfunctions. ■ Regularly wiping the mast clean allows for long-term use without special maintenance. ■ Contracting is as simple as opening the exhaust valve, allowing it to descend slowly under its own weight. No power is needed for emergency contraction. ■ A wide range of optional parts enables various installation forms on the ground, vehicles, rooftops, and exterior walls of buildings. ■ Auto/manual roof masts for mounting on vehicle roofs. ■ Complies with various standards (TUV, MIL-STD, CE, etc.). ■ By locking each section, the height can be maintained for an extended period even after releasing air post-extension.
