  • Keeping it on the Rails: The Importance of Overhead …

    2021/3/30 · Vertical misalignment causes the crane’s load to be unevenly distributed and results also in accelerated wear to multiple elements in the crane structure. Further, not only are the crane wheels and rail affected when rails are misaligned: we commonly see wear structural element fatigue and failure, as well as bridge couplings and axle wear patterns.

  • Boom (Overhead Crane): A horizontal member used to permit hoisting as well as lowering the load at a point other than directly under the hoist drum or trolley. The boom is mounted on a trolley. Boom (Gantry Crane): A trolley runway extension often used to obtain clearance for gantry travel by retracting or raising.

  • Overhead crane is a lifting equipment that spans the width of the workshop, warehouse or material yard for material lifting. The bridge runs longitudinally along the rails laid on the elevated runway beams, which can make full use of the space under the bridge without being hindered by ground equipment.

  • 2021/3/29 · If the weight is very heavy, this pulling action induces a transverse horizontal component of force ( a point load) on the crane girders through the crane wheels. This transverse horizontal force will be transferred to the crane girders through the double-flanged crane wheels on the end carriages and the crane is designed to avoid the possibility of derailment.
