    Single-speed wireless crane remote: 6 direction buttons, START and a mushroom emergency STOP in a narrow 45 mm transmitter. The 24–440 V AC/DC receiver connects to the existing contactor control circuit.

  • Product description

    Wireless crane remote ES-F21-E1-TX – 6 buttons, mushroom STOP, 24–440 V AC/DC receiver

    ES-F21-E1-TX is a radio remote for a hoist or overhead crane with three motion axes. A button press on the transmitter is sent by radio to the receiver, whose relays energise the matching contactor coils. The contactors still switch the motors – just as with a pendant control.

    Key point:
    Six single-speed buttons cover three motion pairs: hoist, bridge and trolley. The mushroom STOP on top is easy to find even with gloves, and the universal receiver supply suits almost any control circuit without an extra transformer.
    Buttons
    6 + START + STOP
    Speeds
    1
    Range
    up to ~100 m
    Receiver
    24–440 V AC/DC

    How it works

    The receiver (205×80 mm) is mounted on the crane or hoist and supplied with the control circuit voltage within 24–440 V AC/DC. Direction relay outputs replace the pendant buttons in the contactor coil circuits.

    START energises the MAIN relay and the main contactor, STOP drops it out. A direction relay stays on only while its button is held; on release the contactor drops out. On loss of radio link the receiver must drop the MAIN relay.

    The operator walks next to the load, sees the hook-up point and obstacles instead of dragging a cable. Fewer knocks during slinging and no more replacing a torn pendant cable.

    Why choose ES-F21-E1-TX?
    A straightforward single-speed remote for a full 3-axis crane with a mushroom STOP on top of the transmitter. A good fit for replacing a worn pendant where the contactor circuit is already in place.

    Main functions

    • 6 direction buttons – hoist, bridge and trolley in both directions
    • Mushroom STOP – found and pressed instantly
    • START button – the main contactor is switched on only by a deliberate action
    • 24–440 V AC/DC receiver – one model for 24 V, 230 V or 400 V control
    • Narrow 45 mm transmitter – comfortable one-hand grip
    • IP65 transmitter – dust and water jets do no harm

    How does it differ from similar models?

    • F21-E1B-TX – Same 6 buttons + START/STOP and 24–440 V AC/DC receiver, but a wider 70 mm transmitter with a 2×4 button layout; a mushroom STOP is not specified for it.
    • EL-F21-2S-TX – Only 2 direction buttons + START – for a single axis, e.g. hoisting only.
    • ES-F23-BB – 10 buttons + START/STOP – extra buttons 1–4 for auxiliary functions.
    • ES-F21-E1B(H) – Compact single-speed remote operating in the EU SRD 868 MHz band.

    Where is it used?

    • Hoists with an electric trolley
    • Single- and double-girder overhead cranes
    • Steel fabrication and welding shops
    • Warehouse and logistics lifting equipment
    • Retrofitting old cranes instead of a pendant
    • Outdoor gantry cranes (IP65 transmitter)

    Use by need

    For the electrician
    Relay outputs replace the pendant buttons – contactors and circuit stay; the universal supply means fewer variants to stock.
    For a manufacturing plant
    The operator works close to the load and sees the slinging – fewer damaged parts and no downtime from a torn cable.
    For a construction site / warehouse
    Control up to ~100 m in open space; the IP65 transmitter suits dusty and damp conditions.

    Practical use

    If the pendant of a workshop crane keeps catching on workpieces and the contactor coils are 230 V AC, supply the receiver from the same 230 V AC circuit, wire the 6 direction relays into the coil circuits instead of the pendant buttons and the MAIN relay into the KM0 circuit. Limit switches and interlocks stay as they were.

    Pros

    • Full 3-axis control – 6 direction buttons
    • Mushroom STOP on top of the transmitter
    • Universal 24–440 V AC/DC receiver supply
    • Narrow one-hand transmitter
    • IP65 transmitter, reinforced ABS housing

    Cons / limitations

    • Single speed only – for smooth positioning choose a 2-speed remote (e.g. ES-F23-6D) with a 2-speed motor or a frequency inverter.
    • No extra buttons for auxiliary functions – for that, ES-F23-BB (10 buttons).
    • Radio frequency and receiver relay current are not stated – confirm before ordering.

    Safety and installation notes

    • The receiver relays switch the contactor coils, not the motor directly – relay contacts are for the control circuit only.
    • The receiver supply voltage must match the control circuit (coil) voltage; range 24–440 V AC/DC.
    • Wire the STOP / MAIN relay so that it drops out the main contactor KM0. Loss of radio link must stop the crane (EN 60204-32) – test this during commissioning.
    • Limit switches (SQ) and the NC interlock between opposite directions stay in the circuit – the radio remote does not replace them.
    • For crane repairs, apply LOTO on the main isolator. The STOP button is not isolation from the supply.

    Quick selection guide

    6 buttons + START/STOP
    Mushroom STOP
    24–440 V AC/DC
    IP65

    Check before ordering:

    • Contactor coil voltage is within 24–440 V AC/DC and equals the receiver supply.
    • Radio frequency of the set (EU SRD bands – 433 / 868 MHz) – check that the frequency is permitted in your country.
    • Whether 3 axes and 1 speed are enough – slow positioning needs a 2-speed remote.

    FAQ

    Can the receiver be connected directly to the motor?
    No. The receiver relays drive the contactor coils and the contactors switch the motor – exactly as with a pendant control.
    What happens if the radio link is lost?
    The receiver must drop the MAIN relay and the main contactor so the crane stops (EN 60204-32). Test it at commissioning by switching the transmitter off during a movement.
    Which control voltage can be used?
    The receiver is supplied with 24–440 V AC/DC, so it suits 24 V, 48 V, 110 V, 230 V or 400 V control circuits. Receiver supply must equal the coil voltage.
    How does ES-F21-E1-TX differ from F21-E1B-TX?
    Buttons and receiver supply are the same. The transmitter differs: ES-F21-E1-TX is narrower (45 mm) with a mushroom STOP, F21-E1B-TX is wider (70 mm) with a 2×4 button layout.
    Can it control a 2-speed crane?
    No – the buttons are single-speed. A second speed needs a 2-speed remote, e.g. ES-F23-6D.
    What is the real operating range?
    Up to ~100 m in open space; less among steel structures. Do not mount the receiver antenna inside a metal box.
