Features:
1. Patented function of working at 360 position - horizontally , above/below horizontal line.

2. Overload protection function.
(1) After rod extends to full stroke , if users continue to pedal the cylinder, at setting value such as 600KGS, it will automatically prevent pressure from rising to protect bed cylinder from overload.
(2) If weight of goods on platform exceeds setting value, relief valve will be triggered to protect hydraulic cylinder.
