    Proportional radio remote with 6 levers, 3 rotary controls and a switch for more complex hydraulic machinery. 2.4 GHz, 24 V DC receiver, IP68.

  • Product description

    Wireless proportional remote control: 6 levers, 2.4 GHz, IP68

    ES-WRC624 is a belly-type wireless remote with 6 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. Six levers control six hydraulic functions, while three rotary controls and a switch remain for extra functions that you assign during installation according to the machine diagram.

    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-WRC624?
    One remote with 6 levers for proportional control – the operator no longer has to stand at the machine levers. More controls in one remote – no second remote or machine-mounted buttons needed for extra functions.

    Technical specifications

    Package contents transmitter and receiver
    Transmitter type Belly type with frame

    Protection rating IP68

    Main functions

    • 6 proportional levers – six hydraulic functions with smooth speed control
    • 3 rotary controls – extra adjustable functions assigned during installation
    • Switch – selecting a mode or an extra function
    • 2.4 GHz radio – ISM band permitted in the EU
    • 24 V DC receiver – fits 24 V on-board systems and control cabinets
    • IP68 – dust-tight and protected against continuous immersion

    How does it differ from similar models?

    • ES-WRC685 – 5 levers with protective frame, Li-ion battery and 230 V charger included
    • ES-CRC687 – 7 levers, 433 MHz, up to ~300 m
    • ES-BT500 – 9 control functions, 433 MHz, up to ~500 m, 2 batteries included

    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 loader crane has six hydraulic sections and an extra function, such as work lights or a rotator mode, the levers are assigned to the sections and the switch and rotary controls to the extra functions. The receiver connects to 24 V DC, and the emergency STOP cuts the valve supply.

    Pros

    • 6 proportional levers
    • 3 rotary controls and a switch for extra functions
    • IP68 protection
    • 2.4 GHz – band permitted in the EU
    • 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.
    What are the rotary controls for?
    They are assigned to extra functions during installation according to the machine diagram. Match the assignment to the valve block or inverter.
    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.
