Description

container side loader

technical field

The invention belongs to the technical field of container loading and unloading, and in particular relates to a container side loader which can be used on freight platforms of electrified railway lines.

Background technique

Container multimodal transport is an important part of modern railway logistics. At present, the scale of multimodal transport in my country is much lower than that in western countries, resulting in a national logistics cost much higher than that in developed countries such as the United States and Europe. At the same time, there are also problems such as insufficient number of railway container handling stations, and most of them are small in scale and insufficient in handling capacity. What's more important is the electrified freight station, because the electric traction system is in contact with the grid (catenary or high-voltage line), so that a large number of stations do not have the ability to directly load and unload heavy-duty containers. The catenary is generally set below the height of 6.5 meters off the rail, and conventional loading and unloading equipment such as container reach stackers and gantry cranes that need to occupy the space above the vehicle cannot actually work. If you need to open a container handling station, you can only apply for the removal of the contact grid or divert the route to use a diesel locomotive to pull it to a special freight yard, which has disadvantages such as long construction period, large investment waste, high operating cost and many environmental hazards.
