Safety First

Falling is a serious concern for all drivers, maintenance individuals and site staff when they walk the top of a pneumatic to open-close the manholes or perform service. As a result, the MAC Trailer Design Team has engineered, extensively tested and now offers a retractable set of hand rails as an optional safety feature available on all the 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 securely locked into position. When retracted, the rails fold into a locked position that is lower than the height of the manholes. As an added measure of overall safety, when the rails are raised, the brakes on the truck-trailer are locked to prevent any movement until the handrail is lowered. The unique safety feature of the retractable handrails is a proprietary design of MAC Trailer and is available as a retrofit kit for all existing trailer makes.
