Alligator shears are generally set up as stand-alone shears; however, there are types for excavators. The jaw size can range from 4 to 36 inch (100 to 910 mm) long. They are generally used to cut steel members, such as rebar, pipe, angle iron, or I-beams. Operation Older alligator shears were powered by a flywheel. These shears ran continuously, which posed a safety hazard. Now alligator shears are hydraulically actuated. When actuated, the piston arm extends and slowly closes the upper jaw of the alligator shear, which passes alongside the bed or lower jaw of the shear to perform the cut. Uses Alligator shears are used for cutting long metal stock or scrap, generally where accuracy is not an important consideration, and the size or shape of the material makes other cutting or shearing options imprac...

Aluminum cans are endlessly recyclable and provide benefits beyond reuse. Here are just a few ways your recycled cans are valuable. Aluminum can recycling is beneficial for individuals, communities, organizations, companies and industries. Environmental Benefits Recycling aluminum cans saves precious natural resources, energy, time and money. Aluminum cans are unique: Within 60 days, a can is recycled, turned into a new can and back on store shelves. Aluminum is a sustainable metal and can be recycled over and over  again. In 2007, 54 billion cans were recycled, saving the energy equivalent of 15 million barrels of crude oil – America’s entire gas consumption for one day. Economic Benefits The aluminum can is the most valuable container to recycle and highest consumer recycling rate in the U.S. Each year, the aluminum industry pays out more than $800 million dollars for empty aluminum cans — that’s a lot of money that can go to o...
