SF-HHA-75-165 I-beam Trolley
The product consists of three main parts: flat cables, four-wheel trolleys for carrying cables, and guide rails. The flat cable is made of non-flammable material, suitable for indoor and outdoor use and places exposed to oil stains, with 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-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 that cause dust accumulation on indoor sliding lines and short circuits due to outdoor icing, which affect usage. 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, 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 vehicle). Through the spring puller on the 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 prevent the cable from being subjected to tension), all trolleys are driven 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, safe and reliable.
III. Main technical data of cable sliding line:
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 1.5-50mm23. Ambient temperature: -20°C~+90°C4. Running speed of four-wheel trolley: <90m/min5. Working life of four-wheel trolley: <3200h6. Maximum allowable static load: 150kg
IV. Ordering information for cable sliding line
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 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 according to the allowable cable sag space.
4. Number of coupling connectors:
Based on the total rail length, accessories are needed 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, each set includes:
1. Rail stopper: 1 piece
2. Rail starting end cable fixer: 1 piece
3. Puller frame (traction vehicle): 1 piece
