Tipper refers to a kind of large-scale mechanical equipment used for tipping bulk materials of railway gondola. The loading and unloading machinery which can turn over or tilt the rail vehicles to unload them is suitable for ports with large transport volume and industrial sectors such as metallurgy, coal, thermal power, etc. Mine trucks under the mine are mostly unloaded by small dumpers.
The main forms of dumpers are rotor type and roll type. Rotor dumpers are the most widely used. Rotor dumper is characterized by light weight and small size. But the cost of ground construction is relatively high. Tilting dumpers are rarely used. The characteristics of rollover dumper are that it has a large self-weight, a large power consumption and a relatively small civil construction cost.
