CLIENT: SPI Mobile Pulley Works Inc. Alabama USA

SERVICE:
Complete hydraulic design, manufacture and installation for operation of spud-lifting system on 60 metre mineral sands dredge.

Torque was selected as part of the project team for the assembly of the mineral sands bucket wheel dredge designed by SPI Pulley Works Inc. USA. Torque designed, manufactured and installed a 100KW power unit to drive the spud-lifting cylinders which in turn drives the dredge. The project included working in conjunction with other selected sub contractors to install internal and external pipe systems during modular assembly on site to operate both the spud lifting system, bucket wheel drive and all ancillary operations. Hydraulic design and manufacture was based on engineering drawings provided prior to dredge manufacture, all manufactured items were supplied in modular kit form to be assembled and commissioned on site.

  • 3D modelling and 2D detailed drawings for manufacture
  • Schematic drawings and parts list
  • Power unit design and manufacture
  • Design and fabrication of high pressure pipe work.
  • Structural integrity pre-test to 1.5x WP
  • Dimensional inspection of pipe work
  • Abrasive cleaning of internal surfaces of pipe work
  • Anti-corrosive protection of joints
  • Interzone paint coatings
  • Design and installation of condition monitoring systems
  • Onsite installation - simultaneous with other sub contractors (remote location)

TESTIMONIAL:
"The service provided by Torque Industries was first rate. This project had adverse working conditions and the Torque personnel never slowed down. They worked when other contractors wouldn't and were instrumental in providing a solid and dependable system for the client. When we had start up issues with some other vendor supplied equipment, they agreed to stay and work to resolve them even though it affected their Christmas holidays. With their vast knowledge of hydraulics and analysis skills, we were able to put the equipment in service quickly. We couldn't be more pleased with their expertise, workmanship and professionalism. We highly recommend them and will use them for our next project in Australia."
