Long-established specialist conveyor equipment manufacturer Dyna Engineering has increased its commitment to local manufacturing, ensuring pulleys with 100 per cent local content still have a place in the industry, with the benefit of dramatically reducing manufacturing lead times.
With an ever-increasing number of projects requiring shorter completion deadlines, Dyna Engineering was at times finding it difficult to commit to the required finishing deadline stipulated in some tenders.
In many cases, this was due directly to the longer offshore pulley manufacturing componentry fulfillment cycle.
The company thought it could be “asking for trouble” in terms of project risk if it kept pressuring its offshore manufacturing suppliers for shorter production lead times to meet those tighter project deadlines.
Dyna is also fully aware of the growing number of local customers now requiring total Australian content in any new equipment.
{{quote-A:R-W:300-I:2-Q:"Dyna Engineering has been operating successfully for decades – through all manner of ups and downs in the mining industry."-WHO:Reddy Emmadi, company’s sales engineer of Dyna Engineering}}According to the company’s sales engineer Reddy Emmadi, Dyna has an enviable and valuable reputation for quality engineering work.
“Dyna Engineering has been operating successfully for decades – through all manner of ups and downs in the mining industry,” he said. “A major reason for this has been our focus on providing consistent quality and honouring our delivery promises.
“Over the years, we have built a strong and loyal band of clients. We have absolutely no intention of letting them down through unacceptably long lead times for offshore manufacturing of pulley componentry. So, we have now removed one of these problems by expanding our own local manufacturing content with our conveyor pulleys.”
Dyna Engineering has capacity to manufacture pulleys up to 1.5m in diameter and with a 3.5m face width, covering most applications.
Pulleys are constructed from either steel pipe or rolled steel shells, and incorporate steel-plate end-discs and quality shafting materials.
“All our pulleys are designed by computer software, incorporating the latest design theories and many years of experience to ensure infinite shaft and shell life,” Emmadi said.
The pulleys incorporate several design features:
-
Static and/or dynamic balancing.
-
Keyless connection of shaft to end-disc using locking assemblies.
-
Shells made of rolled steel plate or pipe with full penetration welding to the end-disc.
-
Pulley shell surfaces available in plain steel, hot vulcanised rubber, rubber, ceramic and direct bond ceramic lagging.
-
K1040, K1045, K1050 or 4140 shaft materials.
-
Crowned or non-crowned.
“We can also recondition used pulleys to give new life through our pulley reconditioning service,” Emmadi said. “Reconditioning is recommended when the shell and shaft are in good condition but the bearings, locking assembly, or lagging may be worn.
“Additionally, we provide a wide range of on-site pulley reconditioning services including critical maintenance and on-site re-lagging in most cases.”
Dyna’s reconditioning services include:
-
Crack testing of the shell and shaft.
-
Bearing and locking assembly replacement.
-
Shell re-lagging.
{{image3-a:r-w:300}}Re-lagging to meet customer requirements includes cold-bonded rubber, ceramic or hot vulcanised rubber and direct bond ceramic lagging – which is available off-site only.
Dyna Engineering pulleys are manufactured under the ISO 9001: 2000 Quality Management System.
The company provides full documentation (MDR) under an agreed inspection and test plan to Australian or international standards.
Dyna Engineering is an Australian-owned and operated company, with its head office and factory in Perth, Western Australia. The company specialises in the design, manufacture and supply of conveyor equipment and related services, which can be tailored to an extensive range of applications, operations and operating conditions.
These designs incorporate common components and assemblies, which allows easy modification from one design to another on short notice.
As an example, the Dyna FastFit range of belt cleaners and adjusters can be converted from polyurethane to carbide blades without major modifications or replacement. Products are of robust construction, which allows them to withstand extremely harsh operating environments and deliver a long, trouble-free service life.
Dyna Engineering thoroughly tests its products in both workshop and on-site situations, to ensure they work as intended and to industry safety standards.
