Classification Context

Section:: PERFORMING OPERATIONS; TRANSPORTING
Class:: HOISTING; LIFTING; HAULING
Subclass:: HOISTING, LIFTING, HAULING, OR PUSHING, NOT OTHERWISE PROVIDED FOR, e.g. DEVICES WHICH APPLY A LIFTING OR PUSHING FORCE DIRECTLY TO THE SURFACE OF A LOAD

Description

B66F covers residual hoisting, lifting, hauling, and pushing devices not classified under more specific subclasses (B66B–B66E), particularly those applying force directly to load surfaces without mechanical advantage systems. This includes vacuum lifters, magnetic lifters, friction-based movers, and similar force-application devices for material handling. The classification encompasses both manual and powered equipment designed for direct load manipulation rather than rope-and-pulley or chain-hoist mechanisms. Adjacent classes address elevators (B66B), cranes and derricks (B66C), and winches and capstans (B66D).

Filing statistics

IPC subclass B66F recorded 146,246 patent applications worldwide between 2013 and 2023. Annual filings grew from 5,324 in 2013 to 20,073 in 2023 (+277%), peaking at 21,467 applications in 2020. The most active applicants in class B66 are INVENTIO (3,843 applications), OTIS ELEVATOR COMPANY (3,709 applications) and SGCC(STATE GRID CORPORATION OF CHINA) (2,987 applications).
