Stackers for Bulk Material Handling


AMECO’s Stackers are used to pile up Bulk Material in longitudinal piles on a Stockyard. Travelling and luffing Stackers store Bulk Material one side or on both sides of a Stacking Yard Conveyor whereas Slewing Stackers create Circular Stockyards.

Stackers are Bulk Material Handling equipment used in the Cement Industry, Power Generation Industry, and Pulp and Paper Industry. The longitudinal piles can either be stacked in a chevron or cone shell shape on a Stockyard.

AMECO travelling and luffing Stackers were designed to store Bulk products in longitudinal piles on one side or both sides of a Stacking Yard Conveyor, which are parts of a Stacker machine used in power plants or in coal mines.

Slewing Stackers are also possible, in order to create Circular Stockyards.

All AMECO Stacker Systems are composed of:

  • Tripper Car, transferring Bulk Material from the incoming Conveyor to the Stacker Boom
  • Travelling Carriage attached to the Stacker Tripper
  • Luffing and Slewing Stacker Boom

Stacker Tripper Car

The Tripper Car is an important part of any Stacker. It is designed to allow the incoming Conveyor to bring the product to an elevated position at any given position of the Stacker along the field Belt Conveyor.

Belt Conveyors are used for carrying coal and minerals in power plants or mining industries.

Every AMECO Tripper Car travelling carriage is fitted with idle wheels, rail cleaners, and rail obstruction detectors.

Stacker frame structure

The Tripper Car frame is fixed on a travelling carriage and consists of sections and wind braces to form one or more sections depending on its final size. It is equipped with Conveyor pulleys, troughing idlers, and belt cleaners.

To handle your Bulk Products, AMECO can provide you with two types of Stacker frame structures:

Stacker with a hydraulic luffing system

The Stacker with a hydraulic luffing system is widely used for coal handling in the power industry and the structure is quite simple.

It consists of a base with four legs on top of which a Stacker Boom articulation support is installed. The legs are connected to travelling carriages either with four or eight wheels, and the back of the base is fitted out with a connecting point for a hydraulic cylinder.

Stacker with cable winding drums luffing system

This Stacker type has a cable winding hoisting drum and hoisting boom. It is mostly used upon the client’s request for large machines when counterweighing of the boom is not feasible. The base of this Stacker structure is equipped with a hoisting boom, a boom brace, and a counterweight boom.

The hoisting drum is installed either onto a second platform or directly onto the hoisting boom. The top of the hoisting boom is fitted out on its top with the upper cable sheaves, while the lower sheaves are installed on a bail connected to the Stacker Boom.

Stacker Boom structure

The Stacker Boom structure is either designed using square tubing for outdoor applications or twin I-beams constructed of heavy plates with bulkheads and wind braces for indoor situations.

The Stacker Boom is equipped with all Conveyor components and belt drive components. Access is arranged at the side of the Stacker Boom structure either on one side or on both, allowing maintenance access for the Conveyor and its components.
