Classification: CPC B  G | IPC B  G

Claim 13:
14. An apparatus for optimizing an antisway function for the transport of a load by a hoisting appliance spanning a hoisting area and comprising a trolley, a reeving system and a tool handling the load, the apparatus comprising:
one or more network interfaces to communicate with a telecommunication network;
a processor coupled to the network interfaces and configured to execute one or more processes; and
a memory configured to store a process executable by the processor, the process when executed operable to:
create a first table giving angle offsets of the trolley leading to a primary sway of the load, depending on physical characteristics of the load and on mechanical parameters related to the trolley, the angle offsets being determined by measurements of inclination angles of the trolley,
create a second table giving probabilities of a secondary sway of the load depending on physical characteristics of the load, on mechanical parameters related to the reeving system and on measurements of acceleration and angular position of the tool,
transport the load in the hoisting area by using an anti-sway algorithm taking into account the first table and the second table, wherein anti-sway algorithm takes as inputs dynamic parameters of hoisting appliance comprising the current position of the trolley, the load and the current angle of the load with respect to the trolley.
