The Vevor manual trolley is built for moving loads along I-beams and H-beams in factories, construction sites, warehouses, garages, and workshops. Its adjustable width fits beam flanges from 2.5" to 8", while the alloy steel construction provides strength and corrosion resistance. Dual wheels help the trolley glide smoothly on straight or curved beams. Safety components including a hexagonal nut, collision bumper, and anti-drop wire pin add secure operation. The compact design also allows for quick installation and dependable everyday lifting performance.
