KMK Engineering - ST36-140

The ST36-140 from KMK Engineering is a radial telescopic stacker, perfect for the quarry, shipping port, mining and stockyard industries. Its 42m (fully extended) radial conveyor, with its 270° arc allows for the stockpiling of various materials, in either manual or automatic mode. It is able to process up to 800 tph, with the material at a density of 1.6t/m³, with a maximum particle size of 100mm.

Its large loading hopper has an in-feed height of 3.9m, allowing the stacker to fit seamlessly into many existing processes. The midsection is hydraulically raised to allow the wheels to swing from travel mode to radial position. Wide wheelbase in radial position offers great stability during operation while the closed travel position allows for safe highway transportation.

Telescopic action is activated by a 219mm-dia drum (1.1 KW motor) and ½” (12.7mm) cable winch package, which moves the conveyor, approximately 0.05 m/s (2764Nm, 2.4 Tonnes pull).
Radial Arms are activated by an electric drives motor, with the travelling speed of 0.1m/s. The radial arms move up and down powered by hydraulic rams.
