Overload limiter is to ensure safe lift hoist the main unit is composed of sensors, operational amplifiers, control actuators and other components loading gauge, which combines display, control and alarm functions in one. The following detailed description of your electric hoist overload limiter works.
Electric hoist overload limiter structure
When the electric hoist lifting work, the sensor is deformed into the load weight signal, through an operational amplifier, indicating the load value. When the load reaches 90% of the rated value, the early warning signals; when the load exceeds the rated load, cut off the power source of the hoisting mechanism.
Electric hoist overload limiter connection methods: electric
rope hoist limiter uses a four-core shielded cable, the "power" mark two lines (red and black) connected with AC 380V, power cord for the limiter, the "normally closed" (blue, yellow) marked two lines connected in series lifting contactor circuit.
Overload limiter controller installation: Depending on the controller can be installed in a door or flashlight mounted on cab can be. Electric hoist controller and sensors with a four-core shielded cable is connected, the factory has been equipped, and can be determined according to user requirements wire length, can also be configured by the user to assemble air plug this cord.
Overload limiter sensor installation: When installing the elastomer against the ropes, and then hand the platen cover the U-bolts to hold the rope, and then tighten the nut wrench to hold the rope around, it can be slightly deformed in diameter , and finally left and add a nut and tighten relax.
These are on the hoist overload limiter works, etc. If you encounter other accessories on electric
Wire rope hoist problems, please contact us.
