Hydraulic cylinder:
As the main transmission device of the stacker, the hydraulic cylinder is also the most important power component of the vehicle. Its quality and stability are directly related to the reliability and durability of the vehicle. The oil cylinder of a high-quality manual stacker is mostly an integrated oil cylinder, and the outer wall of the oil cylinder is mostly covered with black paint, and the touch is even. As far as the cylinder diameter is concerned, the larger the load, the larger its size should be. On the contrary, inferior manual hydraulic stackers mostly use welded cylinders, and the outer wall is welded to save costs.
Soldering joint process:
The main structure of the manual hydraulic stacker is steel, cylinder, and wheels. Most are connected by welding. The process of solder joints determines the excellent workmanship of the vehicle. Excellent welding, very smooth to the touch, without the slightest sense of sharpness, and each welding is very uniform. The inflection points of the steel are also micro-treated, without burrs, to avoid scratching the users. On the other hand, for inferior manual forklifts, the welding parts are cut with steel just like sawing with a saw blade. There are obvious angular burrs and the welding points are not even. There are many places, and some places are few or even absent. One can imagine how to guarantee the quality of this product!
