Tension sensor applied in the electric hoist lifting heavy objects for real-time monitoring

Electric hoist is a collection of motor, reducer and cable drum of small-sized lifting equipment, most still walking with a car, cooperate with single beam bridge crane and gantry crane, form a complete hoisting machinery. Electric hoist is a industrial and mining enterprises, storage terminals and other places necessary lifting equipment. Because of the crane is needed in the process of using different tonnage weight lifting, therefore needs to be equipped with a tension sensor system for real-time monitoring, lifting heavy objects so that the current working situation judgment, make corresponding acousto-optic instructions such as normal hoisting, full load condition, the overload condition and so on.

Split type electric hoist overload limiter generally use shaft pin type tension sensor, S tension sensor or plate ring tension sensor, according to the structure of electric block, choose to pull sensor type. Specific choice, also need to be aware of the load of the electric hoist, ratio, the diameter of wire rope, wire rope, and the power available data, compared with the parameters of the corresponding sensor, so that after buying overload limiter can be put into normal use, apply to ring chain electric hoist.

One-piece electric hoist overload limiter is tied sensor and display instrument, the main use of sensor is next to the pressure sensor. Also need to pay attention when selecting a sensor of the load, wire rope electric hoist ratio, the diameter of wire rope, as well as for the power factor, the comprehensive error generally in plus or minus 0.02% F.S. One-piece electric hoist overload limiter is the advantages of convenient installation, low prices, suitable for wire rope electric hoist.
