Think of all of the heavy items and objects that must be lifted in order to complete a project. Windows and other building materials for sky scrapers, pieces of the Statue of Liberty or the Eiffel Tower, pianos into upper level apartments, fire fighters go up on a lift in order to help put out a fire or rescue someone, the list can go on and on. These thoughts also provoke thoughts of how lifts would have been helpful in the past, before the industrial revolution. How helpful would it have been for the Incans to have a hydraulic lift when then built Machu Picchu or for the Mayans or Aztecs when they built Chichen Itza or Teotihuacan? What about the Egyptians and their Pyramids, I bet lifts would have been helpful there as well.
Many industries require high capacity lifts. These lifts include scissor lifts, vertical ram lifts and vertical reciprocating lifts. Many projects in today’s day and age would be impossible without the convenience and accessibility to high capacity lifts.
The automotive, heavy equipment assembly, vehicle load and transfer, heavy material lifting and conveyor systems are just a few applications that require the use of a high capacity lift.
To be considered high capacity lifts must be able to handle eight thousand pounds or more for work purposes. Their function is to assist in the easy process flow of material handling safety, as well as worker safety. Some mechanical designs using multiple actuators, although this is not as common, can lift up to 20,000 pounds. Some high capacity designs with hydraulics can lift up to 120 thousand pounds or more. Most often, high capacity lifts for material handing are hydraulic because of their cost efficiency.
It is important to remember that high capacity lifts must adhere to or exceed strict national safety codes due to the high risk that its operators are under.
