Butterfly Cover Sealing System

The wing-style butterfly cover is a sealing system powered by two hydraulic cylinders. It operates by rotating from both sides of the cargo body upward to meet and close at the top, forming a distinctive wing-like structure that ensures reliable coverage and protection.

The Wing-Opening Butterfly Cover is an early sealing cover technology driven by two hydraulic cylinders that flip the panels from both sides of the truck bed to close at the top. The arched cover allows for stacked loading, increasing the truck bed’s capacity. With mature technology and easy maintenance, it offers a simple structure and high reliability. This cover is widely used in large-scale engineering projects, such as municipal construction, railways, and highways, for transporting construction debris, sand, gravel, and other materials.
