Frequently Asked Questions
Dumpers and Positioners
- How many cars per hour can I dump?
Since all machinery is custom designed, the only limitation is the capacity of the take away conveyor. Contact us to discuss your specific needs.
- How deep is the foundation for the dumper?
The depth of the foundation is partially dependent on the configuration of the receiving hoppers and the size of the belt feeders. Rotary dumpers with a 3300 TPH capacity have used foundations of only 47 feet deep. Turnover dumpers with a 1500 TPH capacity have been built with a pit depth of 26 feet.
- What is the delivery?
Deliveries range from as little as 8 to 12 months. However, accommodations can be made for client’s special needs. Contact us to discuss your specific needs.
- What are the horse power requirements?
Typically, most rotary dumpers require 100 to 125 HP, turnovers use 150 HP. Positioners vary depending on the cycle time, length of train track loop layout and elevations. Contact us to discuss your unique needs.

- How long does it take to erect the equipment and what are the erection costs?
The HP line of equipment is designed and built to facilitate the erection sequence. Most connections are bolted to eliminate costly field welds.
