DescriptionThis is a 1st level hydraulics training course for anyone involved with mobile hydraulic equipment. As an introductory course it is recommended for those who are new to hydraulic equipment however it is also recommended for trades personnel to supplement their trades training in the area of hydraulic control. This training course is also highly recommended for engineering personnel who are tasked with hydraulic system improvement, system modifications and system design. The course was developed with the idea that hydraulically powered machines are best understood and that hydraulic system problems are more efficiently resolved by those who understand the physical principles that apply to hydraulics.
Target AudienceUsers of mobile hydraulic equipment gain a strong understanding of the principles and applications of hydraulics
