FIELD: lifting devices.
SUBSTANCE: invention relates to a method for controlling lifting machine (2), especially for a shaft lifting installation comprising drive (4) with a corresponding control device (6), rope support (8), at least one lifting cable (10) and at least one hoisting car (12, 14) located on hoisting rope (10) for vertical transportation of transported material. During loading of lifting car (12, 14) lifting rope (10) is stretched due to increased weight of lifting car (12, 14). Lifting rope (10) is retracted at unloading of lifting car (12, 14). In order to compensate for height during loading and unloading of at least one lifting car, drive (4) remains engaged during loading or unloading, and to compensate for change in length of lifting cable, turning angle (α) of rope support (8) is continuously adjusted based on predetermined turning angle characteristic.
EFFECT: disclosed is a method for controlling a lifting machine, a lifting machine and a control device for controlling a hoisting machine drive.
