Installation Precautions hoist electric hoist installation is a very important job nh hoist, not only to prepare for pre-installation, but also noted the need to pay attention to the specific installation. A, to ensure the hoist operation to track ends without derailing or prevent collision damage to body should be set up at both ends of the elastic buffer in orbit. B, the electric hoist installation, you should check whether the plug block with fixed rope loose. Should set ground 0.3t hoist, bare copper ground wire available or sectional φ4-φ5mm on C, track or not less than 25mm2 frame connecting the metal wire. D, electrical equipment for all electric power circuit, the control circuit to ground resistance must not be less than per volt operating voltage 10000Ω. Troubleshooting 1, after the start, the motor does not turn electric hoist can not lift heavy objects ⑴ excessive overload, overload is not allowed to use ⑵ voltage lower than the rated voltage of more than 10%, and so the voltage returns to normal ⑶ electrical failure, broken wire or bad After repair electrical and wiring ⑷ brake wheel and cover rust killed, brake drum tied hoist 300kg, remove the brake drum and cleaning corroded surfaces ⑸ motor sweep chamber, according to the fault handling ⑹ No. 9 wire too small, the replacement of lead hc32t electric hoist, electric hoist Yuanjiang, good reputation by heavy machinery Co., Ltd., Henan Province, generous.
