A retractable set of handrails is now an optional safety feature on all new Mac Pneumactic tank trailers. The handrails, constructed of tubular aluminum, are operated by an air valve located forward of the rear fenders and when raised are locked securely into position, the company says; when retracted, the rails fold into a locked position that is lower than the height of the manholes.
When the rails are raised, the brakes on the truck-trailer are locked to prevent any movement until the handrail is lowered, according to Mac. For more information, go to www.mactrailer.com.
