FIELD: machine building.
SUBSTANCE: proposed support-lifting device. Support-lifting device comprises linear drive mechanism, load sensor and controller. Linear drive mechanism maintains equilibrium state while maintaining first load. Controller is configured to selectively actuate the linear drive mechanism in response to application of the second load to the load sensor. Also disclosed is a method of controlling operation of a linear drive mechanism, a computer-readable data medium.
EFFECT: possibility to actuate support-lifting device with one hand.
