Slide wire of 20 ton overhead crane
There are three types of slide wire of overhead crane including unipolar modular sliding contact line, Tube type multiple sliding contact line and seamless slide wire.
Unipolar modular sliding wire
This wire consists of V shape H type aluminium alloy body guide rail pressure slide belt, PVC insulated enclosure, external type collector and hanging, fixed device. This wire has compact structure and dust proof function, besides, it is easy to maintain and compact. For this advantages, unipolar wire is widely used on occasion that has large electric current, and high operation frequency, fast speed and poor environment.
Tube type multipole sliding contact line
This wire is made up by polyvinyl chloride polymer shell, flexible multipole electric brush set and
Some transmission of copper conductor. For its compact structure, safe and easy maintenance, it is widely used on plant, garage, port, and station.
Seamless wire
This wire use advanced technology, which can always have electricity, for it delivers power by oxygen-free copper. This makes it has better electric conductivity, contact ability and easy to be installed. As the perfect update product, this wire has following features:
1. Easy and save time. This wire adopts no joint installation, which need less space and can save time.
2. Stable, fast and low noise. This wire is made by special material, which has low noise and fast speed.
3. Small installation bending radius. The smallest installation bending radius is 750mm.
