  • Product description

    Wireless proportional remote control: 5 levers, 2.4 GHz, IP68

    ES-WRC685 is a belly-type wireless remote with 5 levers for hydraulic loader cranes, hydraulic machinery and cranes with frequency inverters. The lever position is sent by radio (2.4 GHz) to the receiver, and the receiver outputs drive the proportional solenoids of the hydraulic valve block or the inputs of a frequency inverter. The receiver runs on 24 V DC.

    Key point:
    Proportional control means the speed of movement follows the lever deflection: a slight push moves the load slowly and precisely, full deflection gives full speed. Five levers in a row are the typical set for a truck loader crane: slewing, main and second boom, telescope and grab or winch.
    Controls
    5 levers
    Radio
    2.4 GHz
    Receiver
    24 V DC
    Protection
    IP68

    How it works

    Mount the receiver on the machine close to the valve block or control cabinet and supply it with 24 V DC through a dedicated fuse. Assign each lever direction to a valve section or to the direction and speed inputs of the frequency inverter.

    The emergency STOP cuts the valve supply or the pump drive, and on a crane with a frequency inverter it opens the main contactor KM0. If the radio link is lost, all outputs return to neutral and the movement stops – verify this during commissioning.

    The operator works from the spot with the best view of the load, and smooth acceleration and deceleration reduce load sway and shocks to the structure.

    Why choose ES-WRC685?
    One remote with 5 levers for proportional control – the operator no longer has to stand at the machine levers. A 7.4 V / 3000 mAh Li-ion battery and a 230 V charger are included, and the protective frame shields the levers from knocks.

    Technical specifications

    Main functions

    • 5 proportional levers – five hydraulic functions with smooth speed control
    • 2 key / selector switches – switching the remote on and selecting modes or extra functions
    • Protective frame – levers are shielded from knocks and accidental movement
    • 2.4 GHz radio – transmit power < 100 mW
    • 24 V DC receiver – fits 24 V on-board systems and control cabinets
    • IP68 and Li-ion 7.4 V / 3000 mAh – outdoor work, charging from 230 V mains

    How does it differ from similar models?

    • ES-WRC624 – 6 levers and 3 rotary controls, also 2.4 GHz, 24 V DC, IP68
    • ES-CRC687 – 7 levers, 433 MHz, up to ~300 m – when more functions are needed
    • ES-YLB24 – 4 levers and LCD display, 24 V DC, IP67 – for simpler hydraulic machinery

    Where is it used?

    • Truck-mounted hydraulic loader cranes
    • Timber and scrap handling loaders
    • Hydraulic construction and municipal machinery
    • Overhead and gantry cranes with frequency inverters
    • Retrofitting older machines – adding radio control to manual levers

    Use by need

    For electricians
    the receiver connects to 24 V DC and to the valve coils or inverter inputs, levers are assigned to the wiring diagram
    For manufacturers
    precise load placement at low speed without an extra banksman
    For construction / warehouse yards
    the operator can choose a safe position with good visibility

    Practical use

    If a truck loader crane has five hydraulic sections, then each ES-WRC685 lever is assigned to one section, the receiver is powered from the 24 V DC on-board supply and the emergency STOP cuts the valve supply. The operator stands next to the load and sets it down gently.

    Pros

    • 5 proportional levers
    • Protective frame
    • IP68 protection
    • Li-ion battery and 230 V charger included
    • 24 V DC receiver for on-board systems

    Cons / limitations

    • The 2.4 GHz signal is attenuated more by steel structures and buildings – for large yards choose the 433 MHz ES-CRC687 or ES-BT500
    • Receiver is 24 V DC only – for 12 V DC machinery choose ES-YLB12
    • Receiver outputs must be matched to the valve block or frequency inverter
    • For cranes with simple contactor control a push-button remote such as ES-24-8D is enough

    Safety and installation notes

    • Receiver outputs are for the control circuit: valve coils and inverter inputs. Never connect pump or crane motors directly – only through a contactor.
    • Receiver supply is 24 V DC through a dedicated fuse; valve coils must match the output voltage and current.
    • The emergency STOP cuts the valve supply, the pump or the main contactor KM0; on loss of the radio link the movement must stop (EN 60204-32).
    • Limit switches (SQ), overload protection and hydraulic relief valves stay in the circuit – the radio remote does not replace them.
    • Use a valve block with spring return to neutral; fit suppression diodes on DC coils that do not have them.
    • Before any repair switch off the main isolator or on-board supply, lock it out (LOTO) and relieve the hydraulic pressure.

    Check before ordering:

    • Valve coil type (proportional or ON/OFF), voltage and current, or the inverter input type – send us the data and we will match the outputs.
    • Control circuit voltage – the receiver is 24 V DC; for 12 V DC machinery choose ES-YLB12.
    • How many hydraulic functions and extra switches you need – we will match a remote with the right number of levers.

    FAQ

    What does proportional control mean?
    The speed changes smoothly with the lever deflection. Loads can be lifted and set down gently, without jerks.
    Is it suitable for a crane with a frequency inverter?
    Yes. The receiver outputs connect to the direction and speed inputs of the inverter, and the inverter is set up for the signal type.
    What happens if the radio link is lost?
    All outputs return to neutral and the movement stops. Check this during commissioning.
    Can the pump or crane motor be connected directly to the receiver?
    No. Motors are switched by a contactor; the receiver outputs are for the control circuit, valve coils and the inverter.
    How is the transmitter charged?
    The transmitter has a 7.4 V / 3000 mAh Li-ion battery, charged with the included 230 V charger.
    Is it suitable for outdoor work?
    Yes, IP68 means dust-tight and protected against continuous immersion. Mount the receiver antenna in the open, not behind metal panels.
