A common problem with people in the industry for an extended period of time. I've been working on forklifts for over 40 years as a technician, and a trainer for the last 9 years with no injuries on the job. I've always subscribed to the theory of working smarter, not harder. If you need assistance, don't be too proud to ask for it rather than invite injury by over-extending yourself.
I am retiring next week at age 70, and looking forward to the next chapter of my life working at the golf course.
To be honest, I will miss the challenge of the forklift industry, and the people I have met over the years. But, all good things must come to an end.
Best of luck to all at Forklift Action.
