Push trolleys are still one of the most common ways to attach any type of hoist--whether a manual hoist or electric--to a beam. And to date, we have still sold more Magna trolleys than any other brand. Unlike many other trolleys made in China, Magna makes their trolleys in Korea, using Korean parts. They are produced in an ISO 9001 and TUV-CE certified factory and meet ASME/ANSI standards. Each trolley is tested to 150% of rated load. They feature sealed ball-bearing wheels, designed for standard and wide-flange I-beams, along with anti-drop lugs. Offered in a variety of sizes and capacities.
