    2016/8/2 · Ask the crane mfr what is an appropriate maximum gap, and use that value to write your own spec. Shim to close the gap, and/or decrease the clamp spacing. Have any shims used tack-welded to the beam, and try to only use single shims [vs. a stack of shims] at each location.

  • Crane beam design: Called often also a bridge crane, an overhead crane consists of parallel runways with a traveling bridge spanning the gap. The crane’s lifting component, known as the hoist, travels along the bridge. If the bridge is rigidly supported on two or more legs running on a fixed rail at ground level, the crane is called a gantry crane.

  • The maximum gap between ends of the load carrying flanges shall not exceed 1/16 inch. 1.4.1.2.3 The crane runway shall be designed with sufficient strength and rigidity to

  • 2018/1/11 · The crane span is the measured center-to-center distance between the runway beams. One of the most important measurements you can provide during an overhead crane consultation is the crane’s span. An overhead crane’s span is essentially its width across the bay—or the measured center-to-center distance between the runway beams.

  • A plate shall be welded at the two extremities of the supporting beam to limit the rail displacement due to crane longitudinal actions. A 30 mm gap between the rail and the end plate shall be left to allow rail thermal deformation; this value shall be increased when the total runway length exceeds 100 metres.

  • 2018/1/11 · An overhead crane’s span is essentially its width across the bay—or the measured center-to-center distance between the runway beams. It’s important because it determines how much material is required to build the bridge girders and most significantly affects .

  • CMAA Spec 70 for Overhead and Traveling Cranes, Table 1.4.2-1 Crane Runway RAIL Tolerances. This determines alignment requirement for the crane rail (as opposed to the runway beam). MBMA Metal Building Systems Manua l, Table 6.1: Crane Runway BEAMS Erection.

  • 2008/1/17 · Thus, as is usual, the crane operator can move cargo between any two locations between the crane rails. Due to the large scale of typical industrial overhead cranes and heavy loads, proper alignment of crane rails and crane wheels is crucial to safe and efficient operation.

  • The crane bridge will usually be able to move up and down the runways (what is known as long travel) and a single pair of runway beams can support multiple crane bridges if needed. Overhead cranes, particularly when supported by gantry steelwork, are often confused with, with gantry cranes (where the crane’s columns travel longitudinally and form a single structure with the …
