Speed, precision, effectiveness

The hydraulic system activates all crane movements. The crane ease of use, its long durability, its speed in carrying out maneuvers, and working precision all depend on the scrupulous design process.

For its hydraulic system, Effer chose to adopt special solutions to achieve an excellent result:

Effer hydraulic system

  1. HYDRAULIC SYSTEM FLOW CONTROL

    Large distributor. Effer uses hydraulic distributors in all its range which can control large amounts of oil to perform various maneuvers at the same time without any loss of power.

    Simultaneous maneuvers. Thanks to the Flow Sharing system, the oil flow is optimized for each simultaneous movement required by the operator. In this way (and even if two hydraulic pumps are installed), Effer fits only one distributor to control the crane and its equipment, eliminating the loss of power issue in simultaneous movements.

  2. HYDRAULIC SYSTEM POWER CONTROL

    Compensate the power. Effer fitted a hydraulic flow control system equipped with internal compensators, to maintain the right power and speed for all movements also using different crane functions.

    Progressive speed. The use of the latest hydraulic valves allow you to control all crane movements with gradual and progressive speed variations.

  3. LARGE DIAMETER HYDRAULIC PIPING

    Large pipes. Effer applies large rigid and flexible piping to the cranes. The considerable dimension of the pipes diameter reduces the pressure and temperature of the hydraulic fluid, avoiding power dissipation. Moreover, a pipe with a greater diameter allows a high working speed right from the first maneuver in cold climates. In hot climates it helps to maintain an adequate temperature inside the system.

  4. HYDRAULIC FITTINGS WITH FRONT O-RINGS

    Strong seal. To maximize the pressure-tightness in the pipes’ joint points, Effer exclusively usesfittings with hydraulic seals like front O-rings, which are usually used for more heavy works (e.g.: construction equipment).

  5. HEAT EXCHANGER WITH HIGH COOLING CAPA CITY

    Cold is better. Effer fits a heat exchanger sized according to the most difficult working conditions in the majority of its range. In this way:

    • O il maintains medium-low temperatures, even in particularly warm environments;
    • Oil preserves its physical-chemical properties longer;
    • Components and seals are exposed to less wear.

     

  6. THE BEST HYDRAULIC SEALS ON THE MARKET

    Seals. All seals used in Effer cranes’ hydraulic system are the best in their category and are easy to find on the market.

  7. PROTECTION OF CHECK VALVES

    Gradual movements. The check valves on Effer cranes have also the purpose of eliminating pressure peaks caused by sudden load movements; and that of performing very gradual and precise movements.

    Protected components. The valves are applied to cylinders by means of flanges which ensure they are just marginally exposed to accidental impacts, and maximize working safety.

  8. CLOGGING INDICATOR S FOR OIL FILTERS

    Clean at all times. Effer hydraulic system filters are fitted with sensors indicating if they are clogged. Maintenance can therefore be scheduled, and damage to components caused by using dirty oil is avoided.

  9. HOOK SPEED CONTROL WITH PROGRESS

    Controlled speed. To ensure maximum safety, Effer integrated the PROGRESS electronic control system into the hydraulic system. The system controls the maximum working speed of the crane hook, optimizing it according to boom position, load applied and truck stability.

  10. BIODEGRADABLE OIL

    Think green. Effer hydraulic systems, without requiring replacement of components, are compatible with many types of biodegradable oils present on the market, while keeping maximum effectiveness during operation and respecting the environment*.

    *ask for the technical authorization of Effer to check the suitability of the oil chosen.

Benefits

  • TIME TO MONEY

    Large hydraulic pipes allow for maximum working power and speed right from the first maneuver even in cold climates.

    Time to Money
  • EASY WORK

    All seals used by Effer inside of the cylinders are top of the range and supplied by the major world manufacturers.

  • SURGICAL PRECISION

    The synergy between the hydraulic system and PROGRESS allows you to easily give the most suitable speed to the crane hook, according to the type of maneuver. Effer cranes' check valves allow you to obtain very gradual and precise movements.

  • LONG LASTING

    The large heat exchanger allows the oil temperature to be maintained on medium-low values: Oil can therefore preserve its characteristics longer, exposing seals to less wear. The movement check valve applied to the cylinders by means of flanges can withstand accidental impacts. The filters' clogging indicator allows you to prevent damage caused by the use of not perfectly filtered oil.

  • SAFETY

    The synergy with PROGRESS prevents all sudden crane movements, improving safety on the jobsite.

  • NO LIMITS

    The use of an individual distributor and a compensated proportional control system allows Effer cranes to use maximum hydraulic power in every circumstance. Effer uses hydraulic fittings with front O rings for maximum seal of joints.
