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.
While the control, maneuverability, and power source of a scissor lift is critical to its utility, other characteristics better describe the vertical capabilities of the lift. Stroke: this is the range of height safely attained by use of a scissor lift.
