Product Code:SAE J1814
Title:Operator Controls--Off-Road Machines
Issuing Committee:Hftc1, Controls, Visibility, Anthropometrics, Accessiblty
Scope: General criteria are presented as guidelines for: control device location, resistance, and actuation of hand and foot controls by the machine's operator. The criteria are based upon physical limitations as defined by human factors engineering principles. This SAE Recommended Practice applies to upright seated operators of construction, general purpose industrial, forestry, specialized mining machinery and agricultural tractor categories of off-road, self-propelled work machines as identified in SAE J1116. The criteria presented should apply to most situations. Each situation, however, must be evaluated as to its own function and its relationship to other functions to achieve the desired operation action in normal and emergency situations with high probability. The values for control displacement and resistance apply only to what is required to achieve the desired performance of the function being controlled for the 5th through the 95th percentile person as defined in SAE J833.【英文标准名称】:Ni-Cr-MoAlloy(UNSN06022)WeldedConstructionto800DegreesFSectionIII,Division1
