ASABE Standard For Agricultural-Implement Jacks Revised

ASABE has revised its agricultural implement jack standard to correct data, establish labeling requirements and align the document with a proposed international standard.

The revised standard, ASAE S485.3, Implement Mounted Screw-Type Jacks, corrects values for rated static side torque. The document also adds a requirement that the vertical and side load ratings be clearly printed on the jack label, which will assist users in purchasing the appropriate screw-type jack for both vertical and side load applications. Using properly sized or rated jacks for implements and trailers can reduce accidents and injuries caused by overload forces occurring when the implement or trailer is parked on uneven ground or slopes.

In addition, S485.3 includes changes that are anticipated in the corresponding international standard, ISO 12140:1998, Agricultural machinery — Agricultural trailers and trailed equipment — Drawbar jacks. The revision to the ISO standard is expected to be completed in 2013, after which ASABE will consider adopting it as an American National Standard to replace S485.

Changes to both the ASABE and ISO agricultural implement jacks standards were prepared and proposed by US technical experts to achieve international harmonization, a goal that facilitates manufacturing, safety advancements and product marketing worldwide. ASABE helps ensure US engagement in actions related to agricultural tractors and machinery by serving as the administrator for the US Technical Advisory Groups to several of the ISO committees responsible for such standards.

A copy of the ASABE document can be ordered by contacting ASABE headquarters directly at: martin@asabe.org. ASABE members and those with site-license privileges to the ASABE online Technical Library, at asabe.org, can view an electronic copy of the standard in about four weeks. ◆
