The invention relates to a
master system of a hoist, in particular to an intelligent
digital master system for a hoist and a control method thereof. The intelligent
digital master system comprises an absolute value
encoder, a zero-position self-locking
handle mechanism, a transmission gear and an
encoder fixing device, wherein the absolute value
encoder fixing device comprises a rotary sphere, a fixed panel and an encoder fixing plate; the fixed panel is vertically and fixedly arranged on one side face of the rotary sphere; the encoder fixing plate is fixedly arranged on the lower bottom surface of the fixed panel; the transmission gear consists of a gear I and a gear II; and bull gear and the zero-position self-locking
handle mechanism are coaxially and rotationally arranged at the central position of a rotary panel; the gear II is rotationally arranged on one side of the encoder fixing plate below the gear I; the gear I and the gear II are meshed with each other; and the absolute value encoder is rotationally arranged on the other side of the encoder fixing plate, and is coaxially connected with the gear II. Due to the adoption of a
digital master system of the hoist, a digital function is realized through a hoist master.
