The main products of chain hoists Explosion-proof chain hoists, chain hoists 1: aluminum bronze, beryllium as a blank, explosion-proof chain hoists chain hoists H62 copper alloy shell with proof chain hoists used in explosive occasions, such as chemical, offshore and other operations. 2. Explosion-proof chain hoists rotating gear after high-temperature heat treatment to achieve the gear, according to a high wear resistance. Explosion-proof chain hoists pull small bracelet, chain hoists wholesale lighter weight, easy to carry, beautiful appearance, small size, durable. 3. proof hoists work principle: Hands chain drag chains, bracelets wheels began to turn, friction ratchet brake seat (to be pressed into one) co-rotating, five major axis will rotate sprocket teeth, four teeth of the minor axis and flowers keyhole gear. Thus, the lifting device on the spline sprocket holes on the drive gear lifting chain, lifting heavy objects smoothly. The use of hoists before lifting a rule check all mechanical hoists must be intact, transmission parts and lifting hoists chain lubrication good price, empty operating normally. 2 not allowed to use heavy hook hook hook tip. 3 lifting chain is not twisted and knotted, double chain hoists under hook assemblies can not flip. 4 hook should focus on heavy vertical line, to prevent heavy tilt, flip. 5 Operation First test should be suspended, when after heavy off the ground, such as in normal operation, reliable braking can continue lifting. 6 job can not stand heavy objects on top of the operator to operate, nor will stay in the air after lifting heavy objects and left the scene. 7 lifting process, forbids any person to walk or stand under the weight. 8 may not use non-manual drive mode lifting weights. Pull them when found, shall not increase the tension, stop using it immediately, check the weights and other objects involved, heavy weight exceeds the nominal weight, gourds and other parts for damage. 9 increase or decrease the distance shall not exceed the weight lifting height, to prevent damage to the parts. Do 2 sets of 10 and above with hoists while lifting heavy objects. Hebei chain hoists | Xinyu Lifting | HSZ chain hoist from Qingyuan Xinyu Crane Co. provided.
