A balancing apparatus comprises a rotating shaft (2) arranged on a transition coupler (1), a rotating rod (4) and a top seat (7). The rotating rod (4) comprises an upper and lower end plates (11,12), and a ramp protrusion (13) that is arranged between the upper and lower end plates (12), and is of a sheet protruding structure; when the upper and lower end plates serve as the reference, in the longitudinal direction, the ramp protrusion (13) outward inclines towards the rotating rod, one end of the rotating rod (4) is arranged on the rotating shaft, a pin shaft (5) is arranged at the other end of the rotating rod (4), an eyelet bolt (6) is further arranged on the pin shaft (5), and the rotating rod (4) can rotate around the rotating shaft (2) and hinged to the eyelet bolt (6) through the pin shaft (5). A through hole is formed in the top seat (7), the eyelet bolt (6) penetrates through the through hole in the top seat, a nut (9) is fixedly arranged at the tail end of the eyelet bolt (6), a spring (10) is arranged between the nut (9) and the through hole of the top seat (7), and the diameter of the spring (10) is larger than the diameter of the through hole in the top seat (7). The balancing apparatus prevents a bent head phenomenon in a transition coupler when coupling car-couplers.

A knuckle may include a throat portion having a throat side wall with at least three sections, a first section closest to the knuckle tail, a third section closest to the knuckle pulling face, and a second section between said first and third sections. The wall thickness of said first section may be less than 10% different than the wall thickness of said second section. The throat portion may also include a tail stop side wall with at least three sections, a first section closest to the knuckle tail, a third section closest to the knuckle pulling face, and a second section between said first and third sections. The wall thickness of said first section may be less than 10% different than the wall thickness of said second section.

An article conveyance apparatus couples a plurality of conveyor carriages for conveying articles and enables the coupled conveyor carriages to travel along a conveyance path K. The conveyor carriage is coupled by a coupling part to another conveyor carriage placed in the longitudinal direction with respect to a traveling direction H of the conveyor carriage. The conveyor carriage includes a load cell that is provided in the coupling part and measures a force applied between the conveyor carriages, and a controller that calculates a force F applied to wheels of the conveyor carriage, based on a tension T between the conveyor carriages calculated according to the force applied between the conveyor carriages and measured by the load cell.
