The practical application of the limit switch of a simple analysis: limit switch can be installed compared to a stationary object (such as bracket, door frames, etc., referred to as still life) on an object or movement (such as traffic, doors, etc., referred to animals) on. When an animal approaching Still, Tangshan cargo lifter, rod drive switch contact closure switch contact caused by breaking or broken contact closure. The switch contacts open, change the status of co-operation to control circuit and mechanism of this principle is to use a hydraulic lift. Limit switch is widely used in various types of machine tools and lifting machinery, such as hydraulic lifts, rail chain-type hydraulic lifts, hydraulic freight elevators, lifting freight prices, to control its travel, conduct terminal limit protection. The elevator control circuit, also used the trip switch to control the speed of the car door switch, limit automatic door switch, the car, the lower limit protection. Above Xinxiang City Constant lifting equipment upgrades Ltd provide, if necessary, please call us on the picture, you are welcome to! Experimental results show that: the hydraulic lifts complete power testing needs 86.5wh, and easy hoisting lift complete power testing needs 77.4wh, crank cargo lifter, experimental results show that a simple lift more energy. Lifts rise and fall of the existence of the no-load conditions, cargo lifter manufacturers changed the characteristics of a simple lift, test the weight of the goods balance, which makes electrical power with the aggravation of goods and reduced energy consumption to avoid the traditional lift phenomenon, with a simple lift gear, with the situation of unequal weight of the goods, so that more uniform power distribution, to avoid wasting resources elevator, so energy losses to a minimum.
