Before planning winter repairs, plant managers should analyze the access they provide drivers for opening and closing of the bulk trailer's top hatch. Producers can use innovative safety cage designs to protect drivers from falls. Manufacturers can custom design fixed-position structures to match a wide range of producer yard activities. Safety cages differ in styles and positioning mechanisms. Materials such as galvanized steel, stainless steel or aluminum may be used.

One manufacturer offers a power unit that can operate up to four separate cages. Keywords: bulk, trailer, access, hatch, platform, cage, Carbis, Hemco J980863
