Expander system from Keech overcomes costly downtime associated with pivot wear

The Expander system distributed through Keech Castings (Australia) offers a cost-effective and long wearing solution to pivot wear.  

Pivot wear is one of the most common and time consuming maintenance issues facing equipment operators in the mining, agriculture, industrial and rail sectors.

Suitable for both small and large pivot applications across a wide range of machinery and equipment, the Expander system eliminates the need to weld and line bore worn pivots.

Robert Everett, Keech Marketing Engineer explains that replacing traditional pivot systems is a time consuming and costly process, which often takes days because of the need to weld and line bore the lugs prior to fitting a replacement.

The Expander System enables the new pivot to be installed directly into the worn hole. When the fasteners are tightened, the tension washers press the slotted sleeves up the tapered ends of the pin axle and the sleeve expands to conform to the existing wear pattern.

Ease of installation is a key benefit of the Expander system and it can be retrofitted to virtually any machine with pivots. It can usually be fitted on-site regardless of restrictions, and even in underground mining applications.

The Expander system was introduced in the Australian market in December last following 50,000 hours of field testing. Since its introduction in the United States 30 years ago, the Expander system has been fitted in more than 2,500 machinery makes and models.

Available in all sizes and for all machinery types, the Expander system reduces downtime and decreases the lifecycle costs of machinery maintenance.

Push Incorporated, a United States utility contractor specialising in telecommunications, electrical, municipal water, wastewater and trenchless technologies, has been using the system for the past six years.

Ray Wick from the company said that they had to continually line bore the swing frames for their fleet of 50 John Deere backhoes. The Expander eliminates the need to line bore, saving the company hours of labour. Additionally, the Expander offers much better quality than the OEM pins.

According to Robert, Keech was selected as the Australian distributor due to its national network of sales staff, technical backup capability and experience in mining, agriculture, construction and industrial markets.

These market segments have received the Expander system well, recognising it as a cost effective and time conscious solution to overcoming one of the most common equipment maintenance issues.

The Expandes come with a 10-year or 10,000-hour manufacturer warranty.
