Crane bearing applications

Crane is in a certain range of vertical lifting and carrying heavy loads of multi-level action lifting machinery. Also known as crane. Belongs to the material handling machinery, but also for marine crane bearing, working characteristics of the crane is to do a batch Appropriate institutional movement, that in a work cycle Reclaimer, transport, unloading and other movements are alternately work Development and use of cranes on the market more widely. Crane hoisting mechanism includes running mechanism, luffing mechanism, slewing mechanism and metal structure. Hoisting mechanism is the basic working mechanism of the crane, mostly by hanging systems and winches composition, but also lift weights by the hydraulic system. Operational mechanism for horizontal transport of heavy or longitudinal adjustment of the position of the crane work, usually consists of motor, reducer, brake and wheel components. Luffing mechanism is equipped with only the jib crane, when the jib looked amplitude decreases, the amplitude increases when bent, sub balanced and unbalanced luffing luffing two. Boom slewing mechanism for causing rotation is determined by the drive means and the rotary bearing device component. Metal structure is the skeleton of a crane, the main carrier such as bridge, jib and mast can be a box-shaped structure or truss structure,But also for the web structure, and some can be used as a steel support beam.
