Single-pole Multi-pole Tubular Sliding Contact Line Custom 200A-2500A
Darui Electric recommends
This new product is mainly used on the cigarette production line designed by Italian CMOAS Company for China. It is a key component provided by CMOAS Company. On tobacco production equipment such as the DM-type material distribution and conveying device, MCA series silo-type feeders, SAM series silo-type feeders, SAD series tobacco storage cabinets, and FIFQ series stacking-type tobacco leaf storage cabinets designed by CMOAS, it is the most ideal product for power supply to mobile crane motors and electrical appliances, as well as signal transmission for electronic devices. It is an indispensable supporting product for various crane manufacturers. This product can completely replace CMOASS Company's products. Its product structure, shape, and performance are the same as imported products, and all parts are produced with mold production. It can be interchangeable with imported products. It can also be used as spare parts for equipment and is widely applicable to power transmission and distribution systems of all mobile cranes in railway crossings, ports, freight yards, cigarette manufacturing, and other places.
II. Structural Characteristics and Working Principle
This product consists of three main parts: flat cable, four-wheel trolley for carrying cable, and guide rail. The flat cable is made of non-flammable material, can be used indoors and outdoors and in places with oil contamination, and has 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. It overcomes the disadvantages of indoor sliding line dust accumulation, outdoor icing causing short circuits and affecting use, and has domestic unique characteristics. The rail unit length of 4-6m uses coupler connectors and can be extended to any length as needed.
The working principle of this product is shown in the engineering application diagram (1). The feed end of the flat cable (connected to the 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, it is fixed at appropriate intervals (1-2.5m) to the four-wheel trolleys carrying the cable. The cable end (connected to the power supply) is fixed to the last trolley (traction vehicle). Through the spring pull of the pulling vehicle, the trolleys move back and forth, and through the dragging effect of the cable (if the length exceeds 20m, a traction rope should be considered to protect the cable from tension), all trolleys are driven to slide freely in the rail at any speed. The rail is easy to install, requires no adjustment, and has advantages such as contactless power supply, making it safe and reliable.

IV. Ordering Instructions:
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 electrical equipment and junction box.
3. Number of four-wheel trolleys
Generally 1/2 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 length of the rail, rails exceeding 4m require accessories.
