The lowest or basic strength of aluminum and each of its alloys is determined when the metal is in the annealed or soft condition. This is designated as the O (letter O) temper. For example, the annealed condition for alloy 1145 is written 1145-O.
What is a scissor lift? A scissor lift is a type of aerial work platform used to lift personnel. These platforms extend and retract vertically with the help of the scissor linkages that fold in a crisscross manner. Scissor lifts are typically electrically powered although there are some that are powered by internal combustion engines.
Buying vs. Leasing Scissor Lifts. Purchasing a scissor lift is a significant investment. It is best to consider this option only if you are going to be using the lift year round and have a means for transporting in to and from the job site. A brand new, 19-foot lift will cost you $12,000 to $14,000, while a new 30-foot lift can cost $20,000 to $24,000. For those who only need to use the scissor lift occasionally, renting is generally the preferred option. This eliminates maintenance fees and the expense of time and effort it takes to transport the lift to and from the work site. How to Rent a Scissor Lift
