Lift tables can come in a vast array of configurations and can be built to suit various highly specialized

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.

Standards

In Europe there is a published standard BS EN 1570: 1998 + A2: 2009 Safety requirements for lifting tables. Standard EN 1570-1 is now EN 15701-1:2011+A1:2014. It is a Type C standard and compliance with this standard confers conformity with the Machinery Directive, 2006/42/EC. Work is already being undertaken to revise this standard and possibly split it into 3 parts. It specifies the criteria for the raising and lowering of goods and/or persons associated with the movement of goods carried by lifting tables.

In North America, the American National Standards Institute (ANSI) approved and published the ANSI MH29.1:2012 standard in February 2012, itself a revision of the previous MH29.1:2008 standard.[3]

Common accidents

The most common types of accidents involving a scissor lift caused by misapplication of the machine, obstacles, misuse of the equipment, and lack of maintenance.
