Safety precautions when lifting hoist rigging

• 1, to avoid extortion or shock loads.• 2, to avoid tearing sewing together parts or even hoist overload.• 3 , when lifting, materials lifting equipment do not twist , with a

noose .• 4, do not use a damaged rigging .• 5, when moving rigging , do not drag it .• 6 , each rigging before each use must be checked.• 7 , nylon has the ability resistant to inorganic acids , organic acids

susceptible to injury .• 8 , nylon when exposed to moisture, strength loss of up to 15 %.• 9 , if the electrical hoist rigging is likely contaminated with

chemicals or used at high temperatures , you should seek the advice of the supplier.

Electric hoist four rope grab and working principle

• mini wire rope hoist four rope grab the pole , jaw plates and beams composed . Four rope grab reclaimer crane lifting reel action relies on the open- closed book cylinder control , since the two ends of the rope wound up reel mounted on the head grab wedge shell, shell and grab wedge articulated head , turning from time to roll up rope wedge shell driven by the rise and fall grabs ; closed book on the open wound of the two tube through the guide rope wound round the head and grab the beam between the pulleys, control grab opening and closing .

• When reclaimer , grab to open the state down to feed on the heap (in this case a closed book open tube does not move ) , the direction of the Department of the lifting cylinder actuated to open a closed book ( hoisting rope does not move ) , its own weight in the hoist grab Next , grab jaw dug into the material , the grab is completely closed, while start hoisting drum roll and open a closed book , will be loaded with grab upgrade to a certain height , start unloading overhead crane to move to grab the position , direction to decrease start to open closed book cylinder ( lifting reel does not move ) , grab discharge opening .

Suppress the use of wire rope rigging and maintenance precautions

• When pressed can be used in wet environments , such as in the workplace or in the open rope galvanized steel wire rope rigging as raw materials to enhance rust resistance .

• Pressed steel wire rope rigging except the wear layer electric hoists winches, mainly due to bypassing the hoist hook and hanging objects were repeated bending caused by metal fatigue gradually broken , so hoist hook or hanging objects with a rope diameter ratio is determined to suppress suppression of the important factors rigging rope life .

• Suppression of rope rigging is mainly used in delivering the goods , such as high strength cord of transport, in the course of the next non- stop hanging objects on a person or object through .
