Cable trolley line, also known as cable trolley contact line or trolley guide rail.
Yangzhou Dabing Electric produces ideal products for power supply of mobile crane motors and electrical appliances, and signal transmission of electronic devices on tobacco production equipment such as DM-type distribution conveyors, MCA series silo feeders, SAM series leaf blending cabinets, SAD series tobacco storage cabinets, and FIFQ series stacking leaf storage cabinets. 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.
The guide rail is formed by cold-rolled steel plate in one cold drawing process to ensure the accuracy of the rail cross-section dimensions, replacing angle steel and other conductive methods that are unsafe, heavy, prone to dust accumulation indoors, ice formation outdoors causing short circuits, and affecting use. It has unique domestic characteristics. The rail unit length is 4-6m, 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. 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 (towing trolley). Through the spring on the towing trolley, the trolley moves back and forth, and through the dragging of the cable (if the length exceeds 20m, a towing rope should be considered to protect the cable from tension), all trolleys slide freely in the rail at any speed. The guide rail is easy to install, requires no debugging, and has advantages such as contactless power supply, making it safe and reliable.
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 to +90°C
4. Four-wheel trolley running speed: <90m/min
5. Four-wheel trolley working life: <3200h
6. Maximum allowable static load: 150kg
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 reach electrical equipment and junction boxes.
3. Number of four-wheel trolleys
Generally half of the total track length; users 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 track length; tracks 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. Towing trolley frame (towing trolley): 1 piece
