lift table
A lift table is a device that employs a scissors mechanism〔(【引用サイトリンク】 title=Scissor mechanism in particular for lift tables - United States Patent 4858482 )〕 to raise or lower goods and/or persons. Typically lift tables are used to raise large, heavy loads through relatively small distances. Common applications include pallet handling, vehicle loading and work positioning. Lift tables are a recommended way to help reduce incidents of musculoskeletal disorders 〔(【引用サイトリンク】 title=Muscoskeletal disorders )〕 by correctly re-positioning work at a suitable height for operators. Lift tables lend themselves to being easily adapted to a specific use. They can work in hostile environments, be manufactured in stainless steel and have equipment like conveyors, turn-tables, barriers and gates easily added to their deckplates.
==Use==
Lift tables can come in a vast array of configurations and can be built to suit various highly specialized industrial processes. The most common lift table design incorporates hydraulic cylinders and an electrically powered pump to actuate the scissor lifting mechanism. Lift tables can also be driven by pneumatic sources, trapezoidal-threaded screw drives, push chains or by hydraulic foot pump when the load is not heavy. Lift tables can be mounted in a pit for floor-level loading, especially useful for access by manual pallet-pump trucks and the mobility impaired or wheelchair users.
Industries that commonly use lift tables include woodworking, upholstered furniture manufacturing, metalworking, paper, printing and publishing, warehousing and distribution, heavy machinery and transportation.
