Grain chute gate valve black UNITRAILER chute for agricultural trailers 250x355mm
The UNITRAILER discharge gate is a robust structural element designed for mounting on the sides of agricultural trailers. It is used for the precise, controlled, and safe unloading of bulk materials such as grain, corn, rapeseed, feed, and fertilizers. Thanks to a convenient locking mechanism with a wing nut, the user can easily adjust the discharge opening , preventing uncontrolled spillage of crops.
Key features and design:
- solid mounting guides: 45 mm wide side flat bars have factory-prepared mounting holes, which facilitates stable screwing or welding of the bolt to the rear side of the trailer
- convenient flow regulation: a 30 mm wide central locking beam, equipped with an ergonomic wing nut, allows for quick locking of the flap in any position
- smooth operation of the moving element: the 160 mm wide internal closing plate guarantees tightness and smooth movement in the guides
- powder coating: black paint coating effectively protects the steel against corrosion, weather conditions and abrasion during contact with bulk material.
The black discharge gate is ideal for agricultural, farm, and transport trailers where convenient, quick, and controlled discharge of the transported load is essential. Its robust design ensures durability during everyday use, while the simple operation mechanism facilitates use on the farm, during harvesting, grain transport, or warehouse operations.
