HELM Hardware for Sliding Gates Rollers and Trolley Hangers HELM Rollers and Trolley Hangers The decision on the construction of the trolley hangers depends on the door weight (see Page 6). Due to the better guiding in the profile track double-pair trolley hangers with pendulum hinge (fig. 2), than the one-pair construction (fig. 1), ensure significantly better running properties. Trolley hangers for the profile dimensions 100 to 500 are also available with rollers including plastic outer ring for low-noise operation. In this case the load bearing capacity is decreased by approx. 15% to 25% (see Page 6).
