About Our Team

Qualified Mechanical Engineers

Since 1998, the team at Randolph Manufacturing has been servicing industrial gearboxes for clients of all types. Led by Chris, a qualified mechanical engineer with more than 35 years’ experience, our fitters and turners handle all aspects of gearbox work from one-off repairs to complete system overhauls. We can work on everything from right-angle gear drives to tractor power take-off shafts, pumps, gaskets and much more!

We service agricultural, irrigation, pumping and oil mining clients throughout Wee Waa, Gunnedah and Moree. With comprehensive inspections and spare parts available, we ship all types of components throughout Australia and New Zealand. Contact Randolph Manufacturing on 0428 951 125 for more information.

A Notice from Douglas Randolph

Attn: All Customers

Ref: System Performance

Gentlemen:

For the past several years, we have seen our customers increasingly being trapped by torsional problems, which present themselves after a pumping system is manufactured and delivered.

Pump manufacturers assume responsibility for system performance in most cases. Project specifications do not always require that a torsional analysis be performed on the system. When torsional problems present themselves, the pump manufacturer must resolve the problems. The cost to the pump manufacturer is very high at this point and, in many cases, may cause a loss on the project.

Every project which requires a diesel engine driver should have a torsional analysis performed on the system. The initial cost of the torsional analysis is minimal compared to replacing equipment already purchased after the torsional problem is discovered. We encourage you to see that the torsional analysis is performed and encourage engineering firms to require the analysis in their specifications. By doing this, we help create a level bidding field on projects, since everyone bidding would then be aware that the analysis was required. Also, it would be evident that every effort to eliminate torsional damage to the system was taken during the design and material specification stages of the project.

We have enclosed our engineering bulletin and a list of torsional couplings, which we have made available from stock for our products.

Please pass this information along to your colleagues.

Regards,

Douglas Randolph
