Electro-Hydraulic Control Solutions for
Material Handling - Forklifts

The material handling industry encompasses a variety of vehicles and machines that specialize in efficient lifting, rapid transport, and accurate placement of goods and materials of all sizes, shapes, and weights. Telehandlers and fork lifts are the mainstays of this industry, operating indoors in factories and warehouses, or outdoors on farms and construction sites. Safe lifting of materials and safety for the operator are paramount in this field and new safety regulations are requiring redesign of equipment.

HydraForce has a wide range of expertise in material handling applications

We can provide numerous opportunities to improve the control, efficiency and safety of material handling equipment through the use of hydraulic cartridge valves.

  • main_control-circuit
    Flow Sharing Solutions for Forklifts
    • Operate multiple work
      functions simultaneously
    • Multi-function valves regulate
      flow while load holding
    • Load holding with precise and
      stable flow control



    Single-Acting Lift
    • Typical application for a
      single-acting lift cylinder using
      HSPECxx-34 valves for the
      lowering function
    Flow-sharing with higher flow cartridge valves can provide full system control for lifting, lowering and auxiliary functions.
    The use of higher flow electroproportional valves is another easy way to gain greater control of multiple machine functions. With greater flow, you can develop a flow-sharing scheme with the flexibility to handle auxiliary and priority functions.

    • Operate multiple work functions
      simultaneously
    • Multi-function valves regulate flow while
      load holding
    • Load holding with precise and stable
      flow control
