ABSTRACT
Forward type manual hydraulic forklift is a pollution-free, no power handling products, the product has the advantages of compact structure, flexible transportation, simple operation, small turning radius etc.. Apply to factory, workshop, warehouse, station, dock and cargo handling and stacking. For those with fire, explosion-proof requirements of the site ( such as printing workshop, oil depots, docks, warehouses and other ) is more applicable. If match tray packing, container and can realize the transport units, effectively reduce the parts of the collision, scratch and stacking area, reduce the workload of material handling, improve handling efficiency. This statement is on the market investigation, found the manual hydraulic forklift are relatively common, type forklift is also common, but is the lack of forward type manual hydraulic forklift, reach manual hydraulic forklift is a forklift various merit in a body, but the cost is expensive, the market inventory is not much. The design of the main contents include the chassis, the vertical lifting device, advancement device fork, door frame and the design of hydraulic system. Composed of scissors principle to associate scissor fork movement, by trapezoidal screw self-locking, designed only hand can control the fork back and forward, let go does not move forward mode. The proposed scheme tries to prove, the optimal design principle, elaborated reach type manual hydraulic forklift structure design and work principle, demonstrates its applicability, feasibility.
