In the actual transportation demand, especially in some remote mountain villages, manual hydraulic transport vehicles are needed to assist in the handling of goods, and the local ground has not been repaired. When the vehicle is driving on the ground, it sometimes needs to go through rugged gravel roads and sometimes needs to push hard to cross dirt roads, which is a great test for drivers and wheels themselves.
The R & D personnel of guanhang machinery also took into account the problem of the ground on which the carrier travels. In order to improve the stability of the manual hydraulic carrier when driving on uneven ground, we designed and successfully transformed the carrier wheel with a swinging rear wheel structure on the wheel, so that when driving on uneven Road, the two wheels can land at the same time and have good contact, However, ordinary wheels without swinging rear wheel structure cannot land on both rear wheels at the same time, which is unstable and easy to overturn.
