Cable Trolley Model Cable Trolley Model
The product consists of three main parts: flat cable, four-wheel trolley for carrying cable, and guide rail. The flat cable is made of non-flammable material, can be used indoors and outdoors and in places with oil contamination, has certain weather resistance, and compared with round cable, 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 to ensure the accuracy of the rail cross-section dimensions, replacing the unsafe, heavy, indoor sliding line dust accumulation, outdoor freezing causing short circuits and affecting use of angle steel and other conductive methods. It has more 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 pull of the pulling vehicle, 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 protect the cable from tension), it drives all trolleys to slide freely at any speed in the rail. The guide rail is easy to install, no debugging required, and has the advantages of non-contact power supply, safe and reliable.
