In 1980, a siding contractor by the name of Carl Anderson concluded that the method of using 2x4s nailed together, wooden walk planks, wooden cross bracing, and the pump-jacks available at the time to work on the side of buildings were just too dangerous.
The Alum-A-Scaff features square rungs for superior strength, and aggressive anti-slip decking design. The Alum-A-Scaff decking also allows for easier drainage of rain, and melting snow.
The Alum-A-Scaff handles are designed so that the walkboards can be secured together at a Pro-Jack with the Saf-T-Lock chain to form an infinitely joinable walkway. They are made of a super-tough, industrial grade nylon in order to insure their capacity for this purpose.
In 1980, the first aluminum pump-jack pole, which was named the Alum-A-Pole, was invented, designed, and patented by Carl E. Anderson.
Complete system components soon came along and stringent testing was ongoing.
Up to that time, the maximum height allowed by OSHA on pump-jack pole systems was 30'.
In 1983, all test data was submitted to OSHA for review with a request that a 50' shoulder working height to be allowed in the Alum-A-Pole Scaffolding System.
With the Alum-A-Pole that lab tested to 5,000 lbs. and the new telescopic Pro--Jack tested to 3,000 lbs., Alum-A-Pole Corporation received a letter of compliance for a 50' shoulder working height on its scaffolding system. This upgrade to the height to which pump-jack scaffolding could be used, was and still is today, the greatest upgrade ever made in the pump-jack scaffolding industry.
The Alum-A-Pole is made with special structural aluminum, that will not split, bend, crack nor warp with normal usage. Out rubber is made with a compound that is specially formulated for Alum-A-Pole, and is guaranteed not to delaminate for the life of the pole. That rubber is then installed using high-grade solid aluminum rivets. Alum-A-Poles come in 24-foot, 18-foot, 12-foot and 6-foot lengths. Each pole also includes 4 permanent safety stops to insure the joint stays safe in place.
The Pro-Jack features 3 distinct safety mechanisms: the Axial Perma-Clutch, the Saf-T-Brake, and the Auto-Glide.
