Lifting Equipment For Jib Crane

   Jib cranes can be wheeled up and down slewing cranes. The boom design of large jib crane adopts "pole" structure, which is better than that of horizontal arm tower "beam" structure, the proportion of boom structure is smaller, and the maximum weight is larger. In addition to the large jib crane with outside climbing, crawling, walking function, special functions: (1) Large weight modern large-scale construction projects using steel or steel, concrete composite structure, lifting unit weight greatly improved, special-shaped, composite structure usually reach the maximum of 32 tons to reach more than 80 tons. As a result, large jib cranes are configured with heavy-duty main hoisting systems, with a maximum starting weight of 32 to 100 tonnes. (2) Large lifting height due to the use of a special climbing system, the crane can climb with the structure of the whole, rise significantly. (3) Large lifting speed lifting structure high-power, especially the use of a self-contained internal combustion engine drag scheme, with load lifting speed more than 100 Min.Jib Crane
    Hoisting equipment hoisting operations, should carry out safety technical disclosure, to do four clear, namely: Clear work task, the weight of the object is clear, hoisting procedures and operation methods clear, safety precautions clear. Here and you discuss the lifting equipment what are the operational points. 1, strict inspection of the reuse of sling, rigging, prohibit the use of substandard lifting appliances. 2, before lifting should check whether the hanging point is solid, shackle, wire rope use is standard, shackle must not be inverted to use, wire rope must not be inclined to pull. 3, lifting equipment, the equipment should be removed or fixed on the activities of the annex to prevent the Movement of the annex to the injury. Jib Crane 4, lift the equipment from the ground about 100mm, observe the stability and braking performance of lifting machinery, determine the stable and reliable rear can continue to rise. 5, the use of rollers transport or trolley transport, in order to avoid the large equipment when hauling sway or dumping, should appropriately increase the protective measures to increase the stability of the equipment. 6, high altitude maintenance work, should be required to fasten safety belts, strictly prohibit the use of dumping and wire rope and other means of transmission of tools and materials. 7, the use of hand-pull hoist lifting objects, to the hoist's braking, lifting tonnage inspection, verification, hand-pull gourd fixed rope coefficient is greater than 5 times times, if in a shuttle Kok object fixed hand pull gourd, must be good, binding. 8, it is strictly prohibited to remove all kinds of safety devices, safety accessories failure, should be repaired in time to drive. 9, in the lifting process, such as the discovery of voltage drop, brake failure and other phenomena, should immediately ring the bell warning, notify the following personnel quickly out of the way, and with the handle to control the Take-off and landing, in the safety place down the object. 10. Two cranes are not allowed to hang a heavy load together. In case of special circumstances need leadership approval, from familiar with the business of the conductor, good security measures can be hoisted.Jib Crane
