LOAD GRIPPER BUILT AROUND PERMANENT MAGNETS Russian patent published in 2012 - IPC B66C1/04 

FIELD: transport.

SUBSTANCE: cargo is gripped in interaction of system made up of two moving levers interacting via flexible articulation with device magnetic system shafts. Proposed device comprises cargo gripping loop, body with foundation to support magnetic system including several magnetic units made up of stationary and moving permanent magnets. Permanent magnets are fitted on horizontal shafts, their number corresponding to that of magnetic units. Device body is provided with two moving levers, interconnected via lengthwise slots and connected with load gripping loop.
