How to correct and effective 5 ton electric chain hoist maintenance of rope wire rope hois

Clear these two points, we can make a detailed maintenance procedures , and not limited to a corner. I am in the process of maintenance , I always check the strength of their rope , the students also do regular checks of at least six months to conduct a comprehensive inspection to ensure strength. Use rope , do not rub with 5 ton electric chain hoist other objects , nor would like to drag the edge of the ramp plate , so as to avoid sharp edges cut steel wire rope . If the process of using electric hoist , wire rope length is not enough , please do not use thin wire to pick long , so that the rope generate a lot of damage . The correct way to connect with a shackle to ensure the safety rope . Do not use wire rope on hot objects , if you insist , please take some heat insulation measures, or subjected to high temperatures in the rope , strength will be greatly reduced, may cause breakage. Prohibit the use of wire rope hoist overload process , in use, try not to let it impact force at the local contact with other objects to pad things , prevent wear rope , reducing its life. Electric wire rope hoists in use for some time , you must add the oil to the rope , the rope can prevent rusting to some extent , and lubricants can reduce friction between the rope and other objects . When storing , clean it first and then the wire rope lubricant , and then placed in a dry place. After the description of the main means of maintenance , we need to know scrapped standard wire rope , wire rope to be scrapped otherwise maintenance is no longer used . The difference between retirement and non- retirement standard has several aspects , first hoist rope after rope wear , its diameter is reduced , if one-third of the diameter when rubbed off , it should be scrapped . In addition , subject to chemical corrosion should also be scrapped , after the rope overload distortion , structural damage should be scrapped.                                     View Details
Explosion-proof 5 ton electric chain hoist and trolley failure easily what

Keiko lifting a lesson to everyone , so you can easily troubleshoot proof electric hoist failure. Investigation and proof electric hoist failure investigation first going to check proof 5 ton electric chain hoist power fuse is blown . If blown a phase , proof electric hoist motors are single-phase start, the starting torque is zero , the motor can not rotate , replace the fuse enough . And when you want to know not only to check the motor circuit , control equipment should also check the wiring is correct , and if AC contactor contacts caused by poor contact line can not be turned on , the application will contactor contact scar sandpaper polished , but also check the core and pull off , with or without jamming phenomenon , if necessary, replace the contactor . When the grid voltage is too low , the starting torque is proportional to the square of the voltage , the acceleration torque can not overcome the load torque , reach operating speed should be increased to the grid voltage. Explosion-proof electric hoist stator winding phase short circuit , earth or open circuit , winding ground floor when there is access at the lead , you should open the junction box checked. If the load is too large or faulty mechanical drive shed general proof electric hoist motor power is a reasonable match , lifting heavy objects can not overload the event of a proof electric hoist can not rotate , first remove the load , such as the normal starter motor , gear box etc. Description transmission mechanism is faulty and should be checked by dragging bodies , clear the fault.                                     View Details
5 ton electric chain hoist brake Issues on the decline

When the brake pads wear serious , not in the rear brake pads touch the brake when the decline occurs . cd1 electric hoist brake failure Solution: When the brake decline or failure , you should immediately stop using the brakes adjusted . Specific operational procedures are: 1 Remove the motor hood . 2 Remove the three screws . 3 Tighten the clamping nut right , pay attention to first tighten a screw . 4 Reinstall the screws , install hood . Adjusted immediately after the first not fully loaded , you should first find a try hanging small items , such as the decline or do not have brakes , the process can be re- adjusted in accordance with the operation of a hole , you find the situation improved as the rated load weight try hanging .                                     View Details
