Description

Technical Field

[0001] This utility model relates to the field of vehicle painting technology, specifically a heavy-duty lifting and translating vehicle. Background Technology

[0002] The following problems exist when existing heavy-duty passenger cars are handed over in narrow pits: (1) Due to the limited space inside the pit, the existing transfer car only has a single horizontal movement function.

Conventional hydraulic lifting platforms are prone to uneven load tilting and cylinder asynchrony under loads of more than 14 tons, resulting in positioning deviation of the vehicle body; (3) When multiple devices are running on the same rail, the difference in track load between the heavy-duty transfer car and the conventional transfer car can easily cause track deformation or sinking, thereby affecting the handover safety.
