Cable trolley wire is also known as cable trolley contact wire

This product consists of three main parts: flat cable, four-wheel trolley for carrying the cable, and guide rail. The flat cable is made of non-flammable material, suitable for indoor and outdoor use and places with oil contamination, with certain weather resistance. Compared with round cable, it has advantages such as smaller bending radius and longer service life.
The rail is formed by cold-rolled steel plate in one cold drawing process to ensure the accuracy of the rail cross-section dimensions, replacing the unsafe, heavy angle steel and other conductive methods that have disadvantages such as dust accumulation on indoor sliding lines and short circuits caused by icing outdoors, affecting use. It has unique domestic features. The rail unit length of 4~6m uses coupling connectors, which can be extended to any length as needed.
The working principle of this product is shown in the engineering application diagram (1). The starting end of the flat cable (connected to the on-site junction box) is fixed to the starting end fixer of the guide rail, and then according to the space allowed for operation on site, at appropriate intervals (1-2.5mm) it is sequentially fixed on the four-wheel trolleys carrying the cable. The end of the cable (connected to the power supply) is fixed on the last trolley (traction trolley). Through the spring pull of the trolley, the trolley moves back and forth, and through the dragging of the cable (if the length exceeds 20m, consider using a traction rope to protect the cable from tension), it drives all trolleys to slide freely at any speed in the rail. The guide rail is easy to install, no debugging required, and has advantages such as contactless power supply, safe and reliable.

Ordering Information
Edit
1. Rail length (m)
Determined by the user based on the actual running distance of the crane, plus the distance for storing the four-wheel trolleys.
2. Cable length (m)
Actual running length + distance for storing trolleys + necessary length to the electrical equipment and junction box.
3. Number of four-wheel trolleys
Generally half of the total rail length. Users can increase or decrease the number of four-wheel trolleys according to the allowable cable sag space.
4. Number of coupling connectors:
According to the total rail length, rails over 4m require accessories.
5. Quantity of other accessories:
The quantity is determined by the user based on the number of mobile cranes. Generally, each crane requires one set of accessories. Each set includes:
1. Rail stopper: 1 piece
2.
