Telescopic Chute: Loading Chutes & Spouts

MMSTACKER is a premier Chinese manufacturer specializing in high-performance telescopic loading spouts for bulk material handling. Also known as telescopic loading chutes or loading bellows, our equipment provides an eco-friendly and efficient solution for loading trucks, railcars, and vessels. Featuring integrated dust collection systems and full automation, our chutes offer a versatile loading capacity ranging from 100m³/h to 5800m³/h, ensuring dust-free operations for any industrial scale.

What Are The Types of Telescopic Loading Chute?

We provide two types of loading chute for sale, including free fall telescopic loading chute and telescopic cascade chute. For free fall chute, material drops vertically by gravity through the freel fall chute with minimal internal guidance until it reaches the receiving point (truck, ship hold, silo, wagon). For cascade chute, material flows down a series of internal inclined baffles or curved cascade plates, controlling velocity and direction before discharge. For modern bulk terminals and plants, cascade loading chutes are increasingly preferred.
