The composition of the electric transfer cart structure generally includes the frame, running wheels, drive part, power supply system, electrical control system, operating system and other parts as required by the user.
Frame: generally adopt the box beam structure with welded plates, this structure has the characteristics of lightweight, strong bearing capacity and easy arrangement of the whole vehicle structure, which is the priority structure to determine the structure of the electric transfer vehicle. In some special cases, such as the user according to its actual use, the appearance of the electric transfer vehicle is particularly narrow, or particularly low, etc., the box beam structure can not achieve its function, you can use the steel structure, or the box beam and steel mixed structure.
Travelling wheels: The travelling wheels are directly adopted from the crane’s track travelling wheels.
Drive part: generally use F series parallel shaft helical gear reducer, K series spiral bevel gear reducer, crane industry LD reducer structure, in special cases, can also use planetary gear reducer, etc., which reducer drive is used, mainly depending on the specific situation. The principle of selection is that practical, economic and simple. Drive motor, generally using series excitation traction motor, the specific also according to the power supply mode to determine.
Power supply system: power supply mode is divided into the battery power supply, low-voltage rail power supply, slip wire power supply, cable reel power supply and towing cable power supply.
An electrical control system is also related to the power supply method.
There are two kinds of operating systems, wired handle control operation and wireless remote control operation. Users also have to have some special requirements, such as a steel ladle transfer cart, we have to add the device of placing steel ladle on the table; electric transfer cart for tractor, we have to have traction device and so on.
The above are the main components of the structure of the transfer cart, as for the actual structure, it is also necessary to be determined according to the user requirements.
