Difference.Common general port electric cable on loop wheel machine using the deformation that can be distorted, bulge, broken skin, until fractureing core wire etc.
Problem causes cable service life partially short, and a general busy loop wheel machine is several hundred secondary up and down daily, day by day, in twisting resistance
With external wind shake power under the action of cable lower excessive fatigue and gradually deform, it is right with the continuous variation of loop wheel machine height
The technical requirements of matched cable are very different, because cable can be by external environment and wind-force in loop wheel machine operational process
It influences to generate very big rolling power, causes the torsional stress in cable can be bigger, after traditional port electric cable is used for such loop wheel machine, because
It cannot eliminate or alleviate and the core that can frequently break in time for torsional stress, so general common port electric cable is difficult when long on loop wheel machine
Between use.In order to meet the normal operation of port machinery equipment, extends the service life of cable, had in response to this using special
The loop wheel machine private cable of industry is badly in need of us and develops, develops high performance gantry crane frequency conversion type hanging cable, is exactly able to satisfy harbour and hangs
The demand of specialty of machine industry.
It is all vertical up and down during usage that the country, which is exclusively used in harbour gantry crane frequency conversion type hanging cable, at present, so
In operational process, the soaring height of cable can generate great influence to stability in use, so also just determining work
Efficiency.When the height of suspension bridge is higher, under the effect that external environment generates wind-force, the influence to cable is increasing, institute
With just to the anti-stability for waving shaking of cable, more stringent requirements are proposed, because transmitting hinge as main energy, signal,
It plays an important role to safe and stable.Such cable of domestic manufacturer's production is since material type selecting is improper or structure designs not
Rationally, cause cable core to be broken frequent occurrence in cable bend or winding, power-off of cracking, cause harbour machinery that cannot normally transport
Turn；Since the plain edition port electric cable service life period that existing market uses is very short, the replacement frequency is higher；It seriously affects
The normal operation of China's port trade and related places.
