1. The manual hydraulic stacker mast is made of heavy-duty column steel and cold-formed which makes the frame stronger, safer, flexible to move, easy to operate and labor-saving. 2. The hydraulic cylinder of the manual hydraulic stacker adopts high-precision grinding tube, imported oil seal, and integrated valve core, which is convenient for disassembly and maintenance; the pressure relief method adopts the pedal type, the lifting speed is stable, and the safety is greatly improved. 3. The manual hydraulic stacker adopts advanced plastic spraying technology to improve the appearance of the product and increase the durability of the manual hydraulic stacker. 4. The manual hydraulic stacker is a pollution-free manual hydraulic stacker, which has the characteristics of dexterous transportation, flexible operation and small turning radius. 5. The manual hydraulic stacker is suitable for production plants, production workshops, warehouses, stations, docks, airports and other places, especially for places with fire-proof and explosion-proof requirements, such as printing workshops, various oil depots, chemical warehouses and other places. 6. The manual hydraulic stacker can be combined with pallet containers and containers to realize unitized transportation, which not only reduces collisions, scratches, etc., but also reduces workload and stacking area, and greatly improves work efficiency.
