Disclosed is a lifting support, comprising an articulated plate (31) and a U-shaped rib groove (32). Weight reduction holes (33) and two articulating holes (34) are provided in the articulated plate (31), wherein the articulating holes (34) are located in the middle of the articulated plates (31), and the weight reduction holes (33) are located on two sides of the articulating holes (34). The U-shaped rib groove (32) continues between two articulated plates (31), and the U-shaped rib groove (32) is located on an outer side of the weight reduction holes (33). The U-shaped rib groove increases the contact area between the lifting support and a base plate of the carriage, increases a welding region and overlaps reinforcing ribs of the base plate of the carriage to form an integral structure, thereby effectively reducing high stress concentration at the articulated part between a lifting cylinder and the carriage base plate of a mine dumper carriage during unloading, and reducing a failure rate of the part. Further disclosed is a mine dumper carriage provided with the lifting support.
