Bucket Wheel Stacker Reclaimers

Richmond Engineering Works specializes in design/engineering, fabrication and installation along with inspections and upgrades for the work horses of the storage yard; the bucket wheel stacker reclaimer.  Stacker reclaimers are designed as either rail-mounted or mobile (on crawler tracks) and are trenching or slewing type machines. The trenching type is for low-volume, high active storage piles where the slewing type machine is designed for use in facilities with limited yard length and require material to be readily available.  No matter what type of stacker reclaimer is in your plant, REW can design and engineer a machine replacement or a structural, mechanical and/or electrical upgrade using the latest technology to increase machine life, improve safety of machine and personnel, and increase productivity.  We match our machines and upgrades so that we meet or exceed your goals.


Upgrades and Features may include:


  • New PLC Controls to replace old electro-­mechanical relays and to reduce maintenance and increase reliability.
  • Replace the existing Travel Drives with Vector Drives and motors to aid in machine acceleration and deceleration and reduce travel drive maintenance. Gearbox replacement is recommended as well. Install new Digital Slew Drives and reuse the existing DC motors (to save money). AC Drives and motors can also be used on the Slew Drive.
  • Replace the existing Operator Cab. If not already, the new cab can be relocated to the end of the boom to give the operator a better view of the coal pile.
  • A new Operator Chair can be designed to make it more comfortable and ergonomically easier on the operator. Space in the cab can be saved by some cab controls in the armrests of the chair.
  • Total Automation –By automating and radio modems, cameras and controls, operation of the machine can be done remotely (or locally). This will free up valuable plant personnel.
  • Replace the aging and leaking HPU – Hydraulic Power Unit on the Luff/Hoist with redundant HPU.
  • Replace old style height and position sensors with state-­of-­the­-art Sensors such as lasers, encoders and proximity switches. Add a MMI/HMI Operator Interface system to give the operators a complete overview of the machine operation and current status.
  • Replace the hydraulic drive system on the Boom Conveyor Drive with a motor, gearbox and AC Drive to eliminate leaks and improve reliability.
  • Replace outdated M­G set driving the Bucket wheel with a Vector Drive System.
  • Install a Vector Drive on the Luff/Boom Hoist to reduce wound rotor problems.
  • Replace the existing Festoon to make it more reliable.
  • A secure, high-speed Ethernet Radio Modem that will allow voice, video, and control of the S/R can eliminate the need for a cable reel.
  • Upgrade to a Monospiral Wound Cable Reel to assure reliability and to reduce space.
  • Luffing Pin Repair and Luffing Cylinder Replacement.
  • Hinge Pin Replacement.
  • Upgrade Bucket Wheel Drive System.
  • Bucket Wheel Shaft Bearing Replacement.
  • Bucket Wheel Replacement.
  • Provide Replacement Buckets.
  • Replace Hydraulic Drive on Bucket Wheel Motor.
  • Installation of new Travel Trucks and Equalizers.
  • Install new Platform Electrical Room Trailer Structure.
