Illustration of mine hoists • The whole hoisting process of the mine hoist can be divided into five stages of acceleration, constant speed, deceleration, creeping and stop brake. During acceleration stage, the hoist accelerates to the maximum speed from static state. The constant speed stage is the main stage at which the hoist runs under constant maximum speed. During deceleration stage, the hoist decelerates to the creeping speed from the maximum speed. The creeping stage is for skip location and safe stopping preparation. • Its working characteristic: The skip repeats moving up and down...
