Abstract

A control method for a balancing lifting gear which includes a lifting motor that can be actuated by a controller and uses a control handle with a force sensor to lift and lower a load-supporting device. In a “Balance” operating mode, the load-supporting device, with or without a picked-up load, is raised or lowered by the controller in response to a force applied by an operator. In order to ensure disturbance-free handling of a load when removing or attaching a load, a “Pick-up” operating mode or an “Assemble” operating mode is selected, in which the load-supporting device is moved independently without the influence of the force of the operator by the controller in the lifting or lowering direction in dependence upon the signals determined by the force sensor. A balancing lifting gear which operates in accordance with the aforementioned control method is also disclosed.
