ST 60 - Wheeled Conveyor

ST60 - Overview

The ST60 is a mobile high capacity-stockpiling conveyor, which is strong and economical to run independently or as a coupling conveyor

The ST60 is versatile and can be used on its own or with other screening plants.

Its portability allows it to work in confined spaces and also where heavier conveyors would find it impossible to manoeuvre.

The ST60 consists of a radial wheel axle, feedboot, conveyor, powerunit (optional) and has a hydraulic raise lower front ram.

Feedboot

The feedboot directs the sand, gravel, coal etc. onto the conveyor belt.

Conveyor:

The main frame can be raised or lowered with a hydraulic cylinder giving alternate stockpiling heights. The conveyor belt can be either plain or chevron, 2 ply, 800mm (32"), 900mm (36") wide, or 1050mm (42") wide.

Radial Wheels

The conveyor is mounted on two swiveling wheels to give radial stockpiling through an arc of approximately 180 degrees.

ST60 - Options

  • Self contained 50 H.P. CAT diesel engine.
  • Electric motor.
  • ST60 Conveyors can be easily coupled to any plant machinery with an auxiliary circuit.

ST60 - Advantages

  • Capable of handling up to 350TPH.
  • Quick set up time typically under 20 minutes.
  • High performance hydraulic system.

ST60 - Applications

  • Crushed stone
  • Sand and gravel
  • Coal
  • Topsoil
  • Wood chip
