Stackers
Resource Technologies offers a variety of stackers that are designed to fit your specific needs.
 
Slewing and Luffing Stacker
This type of stacker is the most versatile since it is able to slew from a stockpile to the other side of the yard conveyor and build equal stockpiles on both sides of the yard feed conveyor. The tripper is connected to the traveling stacker and serves to transfer material from the longitudinal stockyard conveyor onto the boom conveyor. The stacker consists of a rigid box girder design of a three-point system connecting to a slewable upper carriage design by way of slew bearing, slew gear and slew drive pinions. The upper carriage also has the box girder design and carries the boom pivot. The luffing motion is often done by hydraulic cylinder and counterweighted by concrete counterweight designed to slew and pass under the tripper car. Stackers and trippers are designed for variable speed travel and can be quickly relocated from one place of the stockpile to another. This machine can be operated in a manual mode, semi-automatic mode or fully automatic mode from a central control station.
 
Slewing Stacker
A traveling slewing stacker serves stockpiles to the left and right of the stockpile yard conveyor. Controlled remotely, it can build a stockpile in chevron, coneshell, or windrow stockpiling modes
 
Luffing Stacker
The luffing stacker travels along the entire length of the longitudinal stockpile conveyor and serves to build a stockpile on one side of the conveyor only. The tripper is connected to the traveling stacker by way of connecting structure and serves to transfer material to the boom. The stacker consists of a rigid structural design with a boom pivot in the center. The luffing motion is often carried out by concrete counterweight design. The stacker and tripper are designed for variable speed travel and can be quickly relocated from one area of the stockpile to another. The luffing stacker can be operated in a manual, semi-automatic, or fully automatic mode from a central control station. The luffing stacker is the most cost-effective design for a stockpile on one side of the conveyor. With its simple structure, it has fewer mechanical components than the slewing and luffing stacker.

Radial Stacker
Radial stackers stockpile materials in a kidney-shaped pile, slewing between 90° and approximately 360°. Boom angles can be made either fixed or in a luffing motion between +15° to -15°.
 
Wing Stacker
One wing stacker fulfills the function of two luffing stackers and can be used to either stack two stockpiles simultaneously or just one at a time. The material flow comes over a tripper car and is diverted to one or two luffing booms. The structure in the center of the machine houses luffing winches for the luffing motion of the booms and a flop gate to divert the material flow.
