Our I-beam trolley offers versatile adjustment to fit the width of various S, H, W, and M-type I-beams. The trolley width is adjustable for different beam sizes. Equipped with a safety locking ring, accidental changes in trolley width are effectively prevented. Each trolley has four rollers with sealed bearings, ensuring longevity and smooth operation. Additionally, a lifting eye at the bottom enables the attachment of a hoist, enhancing its functionality for lifting tasks.
