Crane automatic transmission gear off the 3 ton electric chain hoist root cause is frequently shift gear in the transmission process because of tooth wear unevenly dip, and axial force is too large,      Locking mechanism efficiency, insufficient to withstand large axial force change gear automatic tripping caused. Obstacle is the root cause of rail and gear transmission gear position or gear shift lever between incorrect, or lack of 2 ton chain hoist motor coordination.    If the shift lever to pull the head deformation or excessive wear (crane pictures), shift interlock device failure, fork and transfer orbit loose connections may cause the gear. Difficult to remove the shift because of illness, drive rails bending or impurities resistance movement difficulties; improper interlock adjustment; clutch electric chain hoist is not clear; locked or ball, not working and so would hinder the movement of interlocking difficult to move. As long as the specific reasons for the failure to detect and take appropriate measures to repair, it is difficult to exclude. View Details

And hook each using a different product performance is different, generally the most common single hook and hook , then a single hook and hook in the use of what is the difference : single hook is the most common kind of hook , simple structure, the use of more convenient , the material generally use 20 # quality carbon steel or 20Mn, forged , maximum weight of not more than 80 tons ; hook is in effect a large weight when it is used , even by force of symmetry , the material is generally of high quality 20 # carbon steel or 20Mn, forged , usually used on more than 80 tons of lifting equipment. I believe the main difference we have known, single hook and hook the most critical is the effect of different weight to 80 tons of the line , because everyone in the purchase and use the hook to pay more attention to use .                                     View Details

I believe many 3 ton electric chain hoist people would ask , hand chain hoists as one of the accessories ; other hand, we often mentioned in the blog chain network optimization . Today, I will introduce a sprocket chain hoists accessories , I believe we can solve a lot of curiosity. We commonly used chain of roller chain , roller chain sprocket tooth is to ensure a smooth chain of energy-saving and launched smoothly into engagement , and ease of processing, the national standard GB / T 1243-2006 specified minimum and maximum alveolar shape and limit parameters , but does not provide specific sprocket tooth . The end face of the sprocket tooth to be effective between the maximum and minimum alveolar shape. Such approach allows the sprocket tooth profile design has great flexibility. It 's commonly used material for carbon steel and alloy steel .                                     View Details

Install link chain electric hoist need to install the chain box first, then connect the power cord, chain lubrication degree is an important factors affecting the service life of the load chain. Lubrication load chain in a timely and effective manner, to ensure the effective service life of the chain. Check the arrangement of the chain, for multi-line chain link chain electric hoist, shall ensure that the hook is not reversed. If the flip, it returned to normal, to ensure that the chain of welding lines. Don't hang on twisted chain hoist loads. Finally, check the working voltage. Electric hoist in use process, we need to do daily maintenance, so as to ensure the normal work of electric hoist can, avoid unnecessary trouble. New installation or after overhaul of electric hoist, first of all should be empty test run several times. But before installation, power of avoid by all means try to turn; Should be done before normal use with 125% rated load, lifting off the ground is about 100 mm, 10 minutes of static load test, check whether the normal; Dynamic load test on the rated load weight, lifting and moving test repeatedly, after test to check the mechanical transmission parts, electrical parts and the connection is normal and reliable; Not allowed to press at the same time two electric hoist pushing in the opposite direction of movement of the flashlight door button. Electric hoist by specialist manipulation, manipulator should fully grasp the safety operating rules, it is strictly prohibited to slanting pull tilt hanging; Installation and maintenance, must strictly check the limit switch is flexible and reliable, when the hook rose to the limit position, hook enclosure to the drum shell of distance must be greater than 50 mm (10 t, 16 t, 20 t must be greater than 120 mm). When the hook fell to the limit position, should ensure the safety of steel wire rope on the drum circle, effective safety strap (must be at least 2 laps; In use, absolutely forbidden in not allowed, environment, and more than the rated load and rated closing times per hour (120). Must by special personnel to regular inspection on electric hoist, found fault take timely measures, and carefully record; After the completion of the work must be total power brake away, cut off power supply.

The location of the operating personnel should be able to see the command staff and drag or lifting objects. 2, check hoist before operation and fixed on the ground, protective measures, electrical wiring, ground wire, braking device and wire rope, etc. All qualified rear can use. 3, use the belt and open gear transmission parts, are to be set a guard, guide pulley shall not use the opening plate pulley. 4, with power and reversing hoist, drum rotation direction should be instructed on the operation switch in the same direction. 5, the distance from the center line of the drum to the first guide pulley, grooved drum should be more than 15 times of the width of the reel, slotless reel should be more than 20 times, when the steel wire rope in the middle of the drum position, the position of the pulley with roll axis vertical. 6, automatic hoist control lever stroke range can not have obstacles. Second, the matters needing attention in the operation 1, the steel wire rope on the drum should be neat, if discover overlap and inclined round, should rearrange the downtime. It is strictly prohibited in rotation by hand, feet on wire rope. Wire rope is not allowed to put out, at least should retain three times. 2, no knot rope, twisted round, within a pitch break more than 10%, should be replaced. 3, job, no one may cross wire rope, object (objects) after the ascension, the operator shall not be allowed to leave the hoist. When resting objects or hanging cage should fall to the ground. 4, job, the driver, signal with a lift to keep good visibility, the driver and the signalman should closely cooperate, obey the unified command signal. In case of power cuts in 5, homework, should cut off power supply, will improve things fell to the ground. Third, after the operation matters needing attention 1, homework finished, should disconnect the power supply, lock the switch box. 2, hanging basket or object should fall to the ground, cleared ground obstacles.                                     View Details
