This wireless control system combines mature technology and reliable performance, making it a best-selling choice for construction and industrial sectors nationwide. Unlike generic remote controls, the F21-2D is optimized for the harsh conditions of concrete pumping, delivering stable signal transmission and precise operation to boost workflow efficiency. Its dual-speed functionality ensures operators can adjust concrete flow rates smoothly, while its rugged design withstands the dust, moisture, and vibrations common in construction sites.
Double-Speed Buttons: Equipped with 2 dedicated double-speed buttons, the F21-2D allows precise adjustment of concrete pump speed—critical for tasks like high-rise pouring or detailed concrete placement. This feature reduces operator fatigue and minimizes material waste.
IP65 Protection Grade: The remote control meets IP65 waterproof and dustproof standards, ensuring reliable operation in rainy, dusty, or humid environments—eliminating downtime caused by weather or debris.
Reinforced Nylon Plastic & Glass Fiber Shell: The housing combines reinforced nylon plastic and glass fiber shell for exceptional durability, resisting drops, impacts, and corrosion. This extends the product’s lifespan, reducing replacement costs.
Long Standby & Large-Capacity Battery: The transmitter uses 2 alkaline No. 5 batteries, providing long standby time to avoid frequent battery changes. This keeps operations running without unexpected interruptions.
≥100 Meters Control Distance: Offers a standard control range of ≥100 meters, with customization options up to 500 meters. Operators can control concrete pumps from safe, distant locations, enhancing on-site safety.
