I. Introduction to Sliding Guide Rail
This product is mainly used in the cigarette production line designed by CMOAS Company of Italy for China. The sliding guide rail is a key component provided by CMOAS. It is used in tobacco production equipment such as the DM-type material distribution conveyor, MCA series silo-type feeders, SAM series leaf blending cabinets, SAD series tobacco storage silos, and FIFQ series stacking-type leaf storage cabinets designed by CMOAS. It is the most ideal product for power supply to moving crane motors and electrical appliances, as well as signal transmission for electronic devices. The sliding guide rail is an indispensable supporting product for various crane manufacturers. It can be used interchangeably with imported products and can also serve as spare parts for equipment. The sliding guide rail is widely applicable to power transmission and distribution systems for all types of mobile cranes in railway crossings, ports, freight yards, cigarette manufacturing, and other locations.
II. Structural Features and Working Principle
The sliding guide rail consists of three main parts: flat cable, four-wheel trolleys for carrying the cable, and the guide rail. The flat cable is made of non-flammable material, suitable for indoor and outdoor use and areas with oil contamination, and has certain weather resistance. Compared with round cables, it has advantages such as smaller bending radius and longer service life.
The rail is formed by one-time cold drawing of cold-rolled steel plate to ensure the precision of the rail cross-section dimensions, replacing angle steel and other conductive methods that have disadvantages such as being unsafe, heavy, prone to dust accumulation indoors, icing outdoors causing short circuits, and affecting usage. It also has unique domestic characteristics. The rail is supplied in unit lengths of 4-6 meters with coupler connectors, and can be extended to any length as needed.
The working principle of the sliding guide rail 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. Then, according to the space allowed for operation on site, appropriate intervals (1-2.5mm) are used to sequentially fix the cable to the four-wheel trolleys carrying the cable. The end of the cable (connected to the power supply) is fixed to the last trolley (traction vehicle). Through the spring puller on the pull vehicle, the trolleys move back and forth, and through the dragging 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 guide rail is easy to install, requires no debugging, sliding guide rail and has advantages such as contactless power supply, making it safe and reliable.
III. Main Technical Data of Sliding Guide Rail:
1. Rated voltage: below AC750V.
2. Material and cross-sectional area of each core wire: rubber-sheathed flat flexible cable, multi-strand copper core wire 1.5-50mm2
3. Ambient temperature: -20°C~+90°C
4. Operating speed of four-wheel trolley: <90m/min
5. Working life of four-wheel trolley: <3200h
6. Maximum allowable static load: 150kg
IV. Ordering Information
1. Rail length (m)
Determined by the user based on the actual operating distance of the crane, plus the distance for storing the four-wheel trolleys.
2. Cable length (m)
Actual operating length + distance for storing trolleys + necessary length to reach electrical equipment and junction boxes.
3. Number of four-wheel trolleys
Generally half of the total rail length; the user can increase or decrease the number of trolleys based on the allowable cable sag space.
4. Number of coupling connectors:
Based on the total rail length, accessories are required for rails exceeding 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, and each set includes:
1. Rail stopper: 1 piece
2. Rail starting end cable fixing piece: 1 piece
3. Pull vehicle frame (traction vehicle): 1 piece
