About Dunlop Mastclimbers
Overview: Dunlop Mastclimbers is an American specialist in mast climbing work platforms (MCWPs). Since 1984, the company has designed, manufactured, rented, and installed mast climber systems for construction, restoration, and industrial projects in the United States, and provides installation training and certification for crews who erect its equipment.
A mast climber is a self-propelled work platform that climbs a vertical mast tied to the building, carrying workers, tools, and materials to the exact working level. Dunlop built its business around these systems, supplying and installing mast climbers on a wide range of structures, including the Empire State Building and power plant chimney stacks. Its modular platforms can be configured straight, around corners, or curved to follow round structures such as turrets, stacks, and silos.
Dunlop is also known for engineering innovation and industry involvement. The company developed a twin-operational setup that runs two mast climbers on a single mast, using mechanical limit switches to keep the platforms at a safe distance, and has taken part in developing the ANSI A92.9 standard for mast climbing work platforms. Through Scaffold Exchange, you can find Dunlop mast climbers and the providers who sell, rent, and install them.

The industry consensus standard ANSI/SAIA A92.9 covers the design, installation, use, and training for mast climbing work platforms in more detail.
