The remarkable difference between the steel wire rope used for the automobile proportional regulator and other general machines is the large and movable metal structure and the combined work of multiple mechanisms. The characteristics of intermittent cycle operation, uneven lifting load, inconsistent movement cycle of various mechanisms, unequal time of mechanism load, and cooperation operation with many people increase the complexity of crane operation, more potential safety hazards and large risk range. There are many accident prone points and serious accident consequences, so the safety of crane is particularly important.
During transportation, the steel wire rope shall be lifted and placed gently to prevent impact and damage to the outer package. The steel wire rope shall be stored in a dry and ventilated room. During use, the I-shaped wheel shall be used to back off the setting out and pay attention to the setting out direction to avoid additional stress. During field use, the direction of the steel wire rope shall be paid to avoid additional stress and bending of the steel wire rope.
Hoisting machinery is a kind of material handling machinery for lifting or jacking heavy objects, which works intermittently and lifts heavy objects. Most of the hoisting machines start to work vertically or vertically and horizontally after picking up the lifting tools. After arriving at the destination, they unload, then empty travel to the picking place, complete a working cycle, and then carry out the second lifting. Generally speaking, when the crane works, the reclaiming, transportation and unloading are carried out in sequence, and the work of each corresponding mechanism is intermittent
