MAST CLIMBERS
Since then, Dunlop's climbers have been used on hundreds of projects worldwide, including the high-profile work on the Empire State Building in New York to repair all of the building's eight corners. Using mechanical limit switches to keep the two mast climbers within a safe proximity, Dunlop designed and installed the first-ever, twin-operational mast climber on a single mast. The lower mast climber was fitted with overhead protection and was used for demolition and limestone removal, while the upper mast climber was used for the installation of the new limestone. This new design allowed the contractor, Abest Contracting, to complete the project one year ahead of schedule, and eliminated the need for work delays from injuries or accidents from equipment use.
Recently, Dunlop Mastclimbers was asked to provide equipment for the restoration of 90 West St., Manhattan, N.Y., at Ground Zero-a 24-month project to repair damage to the North façade caused by the explosions from the Twin Towers. Dunlop used the same two-tier concept from the Empire State Building project to remove all the damaged terra cotta before replacing it with new terra cotta. Because of the efficiency of the equipment, the contractor, Seaboard Waterproofing, was able to complete the project quicker and under budgeted costs. Seaboard's workers said they preferred to use the Dunlop mast climbers rather than regular scaffold frames and swing stages.
Dunlop Mastclimbers has been actively involved in the preparation and implementation of the ANSI A92.9 standard for mast climbers, and the revised edition, to harmonize the standards for mast climbers in line with EN 14 European Standards. Dunlop also has advised OSHA on the safe working practices for mast climbers, and has trained the Carpenters and Laborers Unions of Boston and New York. Further, the company has assisted with the production of safety manuals for these trades on the installation and use of mast climbers.

Hydek
Hydek recently supplied a large mast-climbing system to Ace Masonry in Las Vegas through its local distributor, Ramm It Compaction Specialists.
Glenn Bott with Ace Masonry and Robby Hagan with Ramm It report that the Hydek system greatly increased productivity when compared with the conventional scaffolding traditionally utilized by Ace Masonry.
Ace Masonry, the largest Hydek user west of the Mississippi River, purchased more than 800 lineal feet of Hydek mast climbers, allowing great flexibility when use
