INTRODUCTIONS

            Railway Electric Transfer Carts are used for horizontal load transfers of a wide range of materials, in other words, they are used to carry loads along assembly lines; transfer material from one place to another. Railway electric transfer carts can also be the part of automated crane systems which used to shuttle material, goods, or product to and from manufacturing processes or warehouses. they are equipped with newly safety features including safety lights, bumpers, horns and mushroom type emergency stop buttons to ensure operators safety.

             Railway electric transfer carts are also called electric flatbed car, rail transfer cart for the transport of coils, electric rail flatbed car, on-rail transfer carts, transfer carts on-rail, cable drum power transfer cart, low-voltage electric flat car, electric flatbed transport cart, battery power rail flat cart, electric rail transfer cart, electric mold transfer cart, steel plate electric transfer cart, rail mounted electric transfer cart.

             Railway electric transfer carts powered by battery are anti-high temperature and anti-high explosion, With lifting holes, it is convenient for transfer carts to shipment. They also have features of big starting power, long lifetime and table start. They can run either on the C-form track or S-form track and L-form track and so on. They provide safe and convenient operation and high using frequency. The running distance is not limited.

             Railway electric transfer carts consist of motor, reducer, electric appliance and wheels. Compared with other carts, their size is larger because of the more parts, but they travel flexibly. Their turning radius are small and so that the turning is stable and flexible.

            They can be designed into being semi-manual or fully-automated depending on your requirements. They can be used in indoor or outdoor operations with the fields include foundry, metallurgy, shipbuilding and new factory construction and so on. Railway electric transfer carts can be battery powered and the battery is installed in the carts. The batteries supply the electricity to the motor through the electrical control system. In this way, we can make the carts to start, stop, forward, backward; adjust the speed and so on.

            They are usually used at plant and factory, ship yard, certain production line. The Motor-driven electric rail flatbed carts are  powered by the cable drum. They are developed to remarkably reduce the material handling requirements of cranes and fork trucks and at the same time, provide efficient movement of materials & products through manufacturing facilities. They are also available in a number of configurations specifically designed to suit your needs.

            Different from railway electric transfer carts there are some other type of carts which have no requirement for the construction of the railway or need different power supply.

           Including magnetic coupling transmission device, armature box, and reel three parts.

10.Transmission Device

           The transmission forms of railway electric transfer carts have a V belt deceleration with a two gear reducer.
           Speed reducer for flat car special axle-hung hardened-gear speed reducer, the output shaft is driving wheel axle, gear for hardened gear, has the advantages of small volume, large transmission power, good fatigue strength. Speed reducer and the driving wheel set consist of a transmission device assembly. Through the pole bearing block is mounted on the frame, four bolts each side are used  to fix.

11.Traction Hook

            These electric rail transfer carts can be set up a connection hook, when necessary, can draw other cars or be towed. Pay special attention to when the car is towed; be sure to lift the brake, to prevent gear or triangle V belt damage. And do not exceed the rated speed of flat, otherwise the motor for super rotation state which could damage.

            Box beam structures are adopted on the base of the crane principle and they are combined with the perfect design. With large load capacity, long service lifetime, they are not easy deformation and can effectively ensure the smooth of the platform.

14.Others

Different kinds of  transfer carts
      Railway electric transfer carts are mounted on steel rail for shuttling along a fixed  path. They can be divided into many different types as shown below:

  1. KPT type is powered by the cable laid on the  ground directly. The price is more competitive because of its simple structure, while their distance is often limited in 100 meters.

  2. KPJ type is powered by the cable from the cable reel. Their moving distance is improved to 200 meter compared with the KPT type.

  3. KPX type is powered by the storage battery. This kind of transfer cart is more flexible and safe. While the capacity and  the duty group are all influenced by the storage battery. What’s more, the price and the life span of the battery are important issues.

  4. KPC type is powered by the slide wire along the rail, so the moving distance is unlimited. The slide wire is the key point and also the weakest link.

  5. KPD/PKDZ type is powered by the low voltage  DC power from the rail. The system is more reliable because it is powered by the rail compared with the KPC type, meanwhile, the system is more complicated and expensive.
