Description
Technical field
The invention belongs to special cable technical field, and in particular to a kind of wear-resisting waterproof suspender rubber sleeve flexible cable.
Background technology
China is vast in territory, aboundresources, seashore line length.As China's economic construction continues to develop the lifting of cargo transport
The use of equipment is more and more, especially harbour, harbour, etc. place need substantial amounts of crane gear.
It is an important link in the handling of shipping field goods, the past, we were very low using the artificial efficiency of loading and unloading,
And we are generally loaded and unloaded using crane gear now.Due to crane gear, suspender is from the top of suspension rod in cargo handling process
Move up and down rather than actionless, suspender needs power supply when working, and cable is passed through from the electrical power control cabinet of crane gear
Suspender is connected at the top of suspension rod, and is moved up and down with suspender.Cable is placed at the top of suspender with regard to disk when suspender rises to peak,
Cable is stretched automatically during decline, and cable will bear the weight of itself and also be bent, drawn, be compressed and rubbed against, while China
Northern weather is again colder, and cable is also corroded by lubricating oil and seawater, therefore cable cover(ing) is easy to damage causes electricity
Cable short circuit and core open circuit.One side crane gear is so required to possess to the bending of cable, draw, compressed and rubbed against
Defencive function and cold-proof corrosion-resistant function, and crane gear is under running conditions, it is difficult to accomplish that this, which is clearly, on the other hand
Must take into consideration cable has necessarily counter-bending, draws, compresses and rubs against function and cold-proof corrosion-resistant function, i.e., one in itself
Determine cable when cable is bent by continuously, drawn, compressing and rubbing against at temperature and be maintained to normally to run cable not send out
Raw short circuit and short circuit, insulation and sheath material also do not ftracture, also require cable have high intensity, it is wear-resisting, corrosion-resistant, cold-resistant,
The performances such as waterproof, so far also without a kind of crane gear special hanger cable with above performance.
