I Beam Load Span Practical Machinist. MUSEUM IN A BOX. The main use of the lifting beam is to hoist the Data Acquisition and Controls Systems (DACS) trailer over a steam line. After completing the design of new beam it is require to check stress and deformation of the beam's It consists of lifting devices and a supporting structure for lifting precast beams and precast bridge segments in position for assembling. Along with stress, buckling is also a critical factor in lifting beams that must be addressed in detail to ensure that the . The number of lifting surfaces, shape, size and materials used all contribute to an aircraft's performance. The reason why precast cap beams with pocket connections yielded in some of the test models was identified as inadequate design rather than the pocket effect. are used for a variety of purposes which can include: Reduce required headroom when lifting loads.
