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.
Standard single scissor lift tables offer a stroke (change in height) equal up to 60% of the platform length. A 3,000mm long lift table will typically give 1,800mm of stroke / travel. Double vertical scissor lifts ( one arm set over another) will offer a stroke (change in height) equal up to 120% of the platform length. A 2,500mm long lifting platform will typically give 3,000mm of stroke / travel.
