    (10)hanging. No abnormal phenomenon.
    Work environment temperature of
    (11) CD1 electric hoist for the last 25 ~ +40 ℃
    (12)The CD1 electric hoist does not apply to full of corrosive gas or relative humidity above 85% places, cannot replace the explosion-proof gourd, not lifting the molten metal or toxic, flammable and explosive articles.
    2.CD1 electric hoist may not be side unloading crane weight, prohibit the use of overload.
    3. In the use process, the operator should always check whether there is chaos, wire rope buckle knot, drop groove, wear phenomenon, if there should be excluded, and should always check the rope guide and limit switches are safe and reliable.
    4. In the daily work shall not be artificially limiting device to stop the use of heavy lifting or stop the operation of equipment.
    5.After work, turn off the power switch, cut off the main power supply.
    6.We should set up specialized repair maintenance personnel on a weekly CD1 electric hoist main performance and safety inspection, found fault and remove.
    The brake ring seven, motor fan of the brake wheel, not stained with grease, adjusting nut should be tightened, so as to avoid the brake failure and accident.
    8.CD1 electric hoist each lubricating part should be the amount of the lubricating oil and lubricating oil in a timely manner, to clean, do not contain other impurities. Lubricating oil for about 2 months to replace a. To hoist reducer and reducer before use must add enough oil, lifting gear into the No. 50 mechanical oil device (HJ-50GB443-64). 0.5T, 1t, 2T, 3T, 5T, 10tCD1 electric hoist LKG 1.5kg, respectively, 2.5kg, 3kg, 3kg, 4kg, running into the viscosity reducer for 5.5 ~ 7º E50. number for lubricating oil 0.3kg.

    Eight safety protection device of electric wire rope hoist
    Views:256    2022-01-17 15:09:39

    1.The main isolation switch
    Electric wire rope hoist with the main isolation switch into the line, switch off the main switch crane without electricity, in order to ensure the safety of maintenance personnel. Small single girder crane ground operation (low headroom electric hoist crane) not to set the main isolation switch.

    2.The emergency switch
    Emergency switch should be installed within reach and position in the driver, (some point magnetic crane switch and the emergency switch with a type of control electromagnetic disc, when the electromagnetic disc control switch can not and emergency switch installed side by side) to prepare for an emergency, immediately disconnect the power, ensure the safety of personnel and equipment.

    3.Short circuit protection
    Commonly used short circuit protection device with automatic air switch, fuse, two. Should be set up in the power supply circuit, short circuit protection to do total power circuit.

    4,Zero protection
    In order to prevent the controller failed to institutions in the zero position, the vehicle suddenly start the accident send electric crane driver, the controller is provided with a zero protection.

    5.The loss of excitation protection
    No current in his shock excitation winding DC motor's armature current will increase, resulting in failure. And as the crane hoisting mechanism with eddy current speed regulation, the eddy current brake magnetic loss leads to load descending overspeed phenomenon. In the two place, should set the excitation loss protection.

    6.Over current protection
    Over current relay on the armature circuit in AC motor stator loop, DC motor. When the current exceeds the allowable value, the relay action of the motor power, the motor protection.

    7.Interlock protection
    The door, the access door to crane cab on the hatch door, ascending or escalator mouth, travel switch, the switch is opened, automatically cut off the power supply, the crane can not start, to protect the safety of personnel.

    8.Grounding protection
    For preventing crane metal structure is charged by electric shock injury, setting the ground protection.
    Ground connection to use a section of not less than 150mm2 or 10mm2 flat copper wire, connected by welding. Is strictly prohibited for current zero line grounding wire. By the rectifier power supply AC power lifting electromagnet, electric should be reliable connection between the shell and the crane. Suspension type control button (electric hoist crane hand switch) should also be reliable electrical connection between the metal shell and the crane. Crane and rail office ground resistance point shall not be less than 4.

    Motor protector of CD1 electric hoist
    Views:264    2022-01-17 15:07:26

    The CD1 electric hoist motor protector has the mechanical development of the past for electronic and intelligent, can directly display the parameters of motor current, voltage, temperature, sensitivity, high reliability, multiple functions, convenient debugging, protection fault type of stick out a mile, which reduces the motor is damaged, and greatly facilitate the fault judgment, is conducive to the production site of fault processing and shorten the recovery time of production.

    Due to the continuous development of insulation technology, not only to increase the output of the motor design, and reduce the volume, heat capacity of the new CD1 electric hoist motor is more and more small, load capacity is more and more weak; due to the improvement of production automation, the motor always runs in frequent starting, braking, reverse and variable load and so on many kinds of ways, put forward higher request to the motor protection device.

    CD1 electric hoist motor protection device of traditional dominated by thermal relay thermal relay, but low sensitivity, large error, poor stability, protection is not reliable. Indeed, although many of the equipment installed in the thermal relay, but motor damage and affect the normal production of the phenomenon is still exist.

    The ideal CD1 electric hoist motor protector is not the most functional, not the so-called advanced, but should meet the actual needs, to achieve unity of economy and reliability, high ratio of performance to price. Reasonable selection of protection device type, function according to the actual situation, considering the protector installation, adjustment, simple and convenient to use, it is more important to choose the protector of high quality.

    Six major product quality characteristics of electric wire rope hoist
    Views:475    2022-01-10 12:01:33

    1.Electric wire rope hoist is used for steel wire rope to lift goods, in order to avoid rope quit, but also the guide rope is installed, so as not to cause unnecessary trouble.
