Hand chain chain refers to the chain in the process of lifting a carrier of human drive sprocket, the power output, as a general rule, be about 15 kg.The thickness of hand chain is very important. If hand chain is too thin, the area of the hand chain of contact with the hand will be too little, short-term operation is no problem, if chain hoisting height is too high can cause a lot of damage to the operator's hand. Not only that if the hand chain is less than 4 mm diameter will produce deformation in the process of operation, thus more chute from zipper chain hand wheel. Suggest buy chain in time so it is important to note that the contrast in hand chain, generally normal manufacturer of hand chain is about 5 mm in diameter, please carefully distinguish between the masses of users View Details

( 1 ) cranes run on the line when there is no obstacle , hook or sling and hanging objects underside must be more than 2m from the ground . If you cross the obstacles, obstacles must be over 0.5m high . ( 2 ) for lifting less than 50% of rated capacity of objects , allowing the simultaneous operation of both institutions ; hanging more than 50% of rated capacity objects , only can an agency action . ( 3 ) with the primary and secondary bridge chain block crane hook , do not increase or decrease the main and auxiliary hook ( special exception ) simultaneously. ( 4 ) allowed or hammering and welding work ( when support can ) on the object to be lifted following objects . ( 5 ) must be in the blackout, and hang in there when the power switches flag operations before inspection or repair work done . If you must live operations , there must be security measures to protect , and a special care . ( 6 ) can not just throw things down from the car . ( 7 ) limit switches and interlock protection device should always check . ( 8 ) not allowed to touch the limit switch as a parking solution. When there is a problem ( 9 ) Lift brakes, lifting heavy objects are not allowed . ( 10 ) is hanging objects are not allowed to run over people or equipment . ( 11 ) When the crane unit of welding, to specifically set the ground , do not allow the use of body ground . ( 12 ) is in the lower limit position of the hook must be retained with more turns of the spool safety ropes . ( 13 ) does not allow the crane collide , but does not allow the use of a crane to push another crane to work. ( 14 ) chain block heavy objects , when the liquid metal , explosive and dangerous goods must be slowly lifting off the ground 100 ~ 200mm, test brake reliability. ( 15 ) repair and inspection lamps , the voltage must be below 36V . ( 16 ) bridge cranes all electrical equipment enclosure should be grounded. If the trolley tracks are not in the main beam welding , soldering ground measures should be taken . Cross-sectional area larger than the available ground wire bare copper wire 75mm2 or 10mm2 galvanized flat iron or greater than 30mm2 galvanized round . Ground position or crane cab body should be more than two . Grounding resistance to any point on the power supply neutral point between the crane shall be less than 4Ω. ( 17 ) security technology to regular checks , preflight preparatory work to do .                                     View Details

Down chain is one of the lifting weight lifting work is not too big of a device often used tool chain itself inverted structure is not complicated , the operation is relatively simple, ordinary people can see at a glance , no other auxiliary equipment , is the best choice for small and medium sized plant construction . Our common inverted chain there are two, one is the worm drive , one is a cylindrical gear . Worm drive down the chain from the weight of 0.5T-1T, the worm wheel and coaxial traction on the sprocket on the worm and coaxial , lifting chains , sprockets and traction chains under ; while geared down chain weight of up to 10T, a combination of traction wheels , gears , planetary gear , ratchet screw brakes, traction chain and lifting chain is made . We usually use inverted chain operations must first check the brake mechanism , transmission, chain block and other parts are normal , but also regularly conveyor grease lubrication. View Details
