Rail electric transfer trolley plays an important role in industrial transport, and the choice of power supply method not only affects its operational performance, but also closely related to the cost. Commonly, the power supply methods for rail transfer trolley include cable reel power supply, slide wire power supply, low-voltage rail power supply, etc., which have their own characteristics in terms of cost composition.
Cable Drum Power Transfer Trolley
Cable drum power supply mode of the initial equipment procurement costs is relatively high. Cable drum and supporting cables need to be customized according to the running distance of rail transfer trolley, load capacity, and other factors, and high-quality cables and reel equipment are expensive. In terms of installation, the installation of the cable reel needs to consider the fixing of the reel, the cable laying path, etc. The construction process is relatively complex, and the labour cost and material cost should not be ignored.
In the process of use, the cost of electricity mainly depends on the power and running time of rail transfer trolley, and the difference with other power supply methods is not big. However, the cable is a fragile part; long-term stretching, dragging, and pulling easily lead to outer skin breakage, internal core wire breakage, and other problems. Maintenance and replacement costs are high. Especially in the frequent use of working conditions, the cable replacement cycle may be shortened to half a year to a year, and each time the replacement requires to investment of a certain amount of money.

Busbar Power Transfer Trolley
Busbar power supply method in the initial equipment procurement, sliding contact line, and collector, and other equipment prices are relatively moderate. The installation process is relatively simple, you only need to install the sliding contact line on one side of the track. The collector can be installed on rail transfer trolley, the installation cost is relatively low. In the process of use, the maintenance cost of the sliding contact line is relatively low, as long as the regular inspection of the surface of the sliding contact line wear and tear and collector contact status, and clean up the dust and debris in a timely manner, generally can ensure normal operation.
However, if the sliding contact line fails, the maintenance difficulty is relatively large, and professional personnel and equipment may be required to carry out maintenance, and the maintenance cost will increase accordingly. In addition, busbar power supply mode has higher environmental requirements, and it is easy to have poor contact and other problems in the dust, humidity, and other harsh environments, which may affect the normal operation of electric transfer trolley and indirectly increase the cost of use.
Low Voltage Rail Power Transfer Trolley
Low voltage rail power supply method has relatively low initial equipment procurement costs, and the main equipment includes step-down transformers, rails, and so on. As a power supply carrier, the track is relatively simple to install, and the track laying of electric rail transfer trolley can be synchronized, with low installation costs. In the process of use, the cost of electricity of the low-voltage rail power supply method is similar to that of other methods.
Its maintenance cost is also relatively low, as long as to ensure the cleanliness of the track surface and conductivity are ensured, regularly check the connection of the track joints, generally not easy to appear a major failure. However, there are certain limitations of the low-voltage rail power supply mode, such as higher insulation requirements for the track, otherwise, it is prone to leakage and other safety hazards. The maintenance process requires extra attention, increasing a certain amount of safety management costs.
Cable drum power supply mode: initial investment, high maintenance costs in the later stage; busbar power supply mode: low installation costs, but high environmental requirements, failure maintenance costs may be higher; low voltage rail power supply mode initial and maintenance costs are relatively low, but there are certain safety management requirements. When enterprises in the choice of rail electric transfer trolley power supply mode, they should fully consider their own use of working conditions, budget costs, maintenance capacity, and other factors, weighing the cost differences between different power supply modes, so as to make a suitable choice.
