1 scope
This standard is applicable to all kinds of lifting platforms, including fixed lifting platforms, mobile lifting platforms, self-propelled lifting platforms (driven by DC motor, ac motor) and elevators.
This standard specifies the safety requirements for the design, manufacture, inspection, use and scrap of the scissor type lifting platform.
The cutting fork lifting platform is mainly used for climbing and vertical conveying. It can be used at any height within the range of lifting and dropping height designed by the cutting fork lifting platform.
