Cable Guide Rail
Darui Electric recommends
Cable Guide RailCable Guide Rail is composed of three main parts: flat cable, four-wheel trolley for carrying the cable, and guide rail. The flat cable uses non-flammable materials and can be used indoors and outdoors as well as in places with oil contamination. It 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 cold-rolling steel plate in one pass to ensure the precision of the rail cross-section dimensions, replacing angle steel and other conductive methods that are unsafe, heavy, and prone to dust accumulation indoors and icing outdoors, which can cause short circuits and affect usage. It has unique domestic characteristics. The rail is supplied in lengths of 4-6m with 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 starting end of the flat cable (connected to the 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 set to sequentially fix the cable to the four-wheel trolleys. The end of the cable (connected to the power supply) is fixed to the last trolley (traction vehicle). 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, a traction rope should be considered to prevent the cable from being subjected to tension), it drives all trolleys to slide freely in the rail at any speed. The guide rail is easy to install, requires no debugging, and has the advantages of contactless power supply, making it safe and reliable.
3. Main technical data:
1. Rated voltage: below AC750V.
2. Conductor material and cross-sectional area per core: rubber-sheathed flat flexible cable, multi-strand copper core wire 1.5-50mm2. 3. Ambient temperature: -20°C~ 90°C. 4. Four-wheel trolley running speed: <90m/min. 5. Four-wheel trolley working life: <3200h. 6. Maximum static load allowed: 150kg.
4. Ordering information for cable slide line
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 + storage distance for trolleys + necessary length to reach the electrical equipment and junction box.
3. Number of four-wheel trolleys
Generally half of the total rail length. The user can increase or decrease the number of four-wheel trolleys based on the allowable cable sag space.
4. Number of coupling connectors:
Based on the total rail length, rails exceeding 4m require accessories.
5. Other accessory quantities:
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. Rail starting end cable fixing piece: 1 piece
3. Trolley pulling frame (traction trolley): 1 piece
