The cable slide rail trolley is composed of a track, cable-carrying trolleys, cables, and suspension and fixing components. With its simple structure and complete performance, this product is widely used in mobile power supply and signal transmission systems of lifting and transport machinery in railway freight yards, ports and docks, and tobacco machinery industries.
Cable slide wire is also called cable trolley wire, slide wire guide rail
I. Product Overview of Cable Slide Wire
Produced for DM-type distribution conveyors, MCA series silo feeders, SAM series leaf blending cabinets, SAD series silk storage cabinets, and FIFQ series stacking leaf storage cabinets and other tobacco production equipment, it is the most ideal product for power supply to motors and electrical appliances of mobile cranes and signal transmission of electronic devices. It is an indispensable supporting product for crane manufacturers, interchangeable with imported products, and can also be used as spare parts for equipment. It is widely applicable to power transmission and distribution systems of all mobile cranes in railway crossings, ports, freight yards, cigarette manufacturing, etc.
II. Structural Features and Working Principle of Cable Slide Wire
This product consists of three main parts: flat cable, four-wheel trolleys for carrying the cable, and guide rail. The flat cable is made of non-flame-propagating material, can be used indoors and outdoors and in places exposed to oil stains, has certain weather resistance, and compared with round cable, it has advantages such as small bending radius and long service life.
The rail is formed by one-time cold drawing of cold-rolled steel plate 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 slide wires and short circuits caused by ice formation outdoors, affecting use. It has unique domestic characteristics. The rail unit length of 4~6m is connected by couplers, and 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 at appropriate intervals (1-2.5mm) according to the space allowed for operation on site, 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 reciprocating movement of the spring-pull trolley on the pulling trolley, 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 at any speed in the rail. The guide rail is easy to install, requires no debugging, and has the advantages of contactless power supply, safety, and reliability.

IV. Ordering Information for Cable Slide Wire
1. Track 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 track length; the user can increase or decrease the number of four-wheel trolleys according to the allowable cable sag space.
4. Number of coupling connectors:
Based on the total track length, accessories are required for tracks over 4m.
V. 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. ... (the rest of the content is cut off in the original)
