  • Tower crane service life 2016/4/12 It can be seen that the enormous quantity wide below 80 tm level tower crane, using 10 years or so tower crane should not be used, most have and small products, 31.5 tm, 40 (25 tm, 63 tm, etc.) in worse, and more than 100 tm level condition of tower crane is better. Is common because of the serious overload, if the presence of the fatigue crack as a symbol of life expires, 80 tm below level of tower crane, an estimated 5% of the tower crane early fatigue occurs in ab...
  • Crane removal and maintenance 2016/4/6 Repair and maintenance tower crane removal and maintenance of metal structure 1. strictly enforce the crane steel structure scrapped. 2. The structure of the main force should be checked by metal fatigue strength, weld cracks, structural deformation, breakage, etc., critical welds and base metal weld heat affected zone of the main structure of the force should be checked, if found abnormal, it should be treated. Check the structural members according to the following...
  • The basic parameters of the crane 2016/3/31 The basic parameters of the tower crane are 6: Machine lifting moment, from the weight, maximum weight, work rate, and lifting height gauge, where lifting torque determined as the main parameter. ① lifting torque (tm). Lifting moment is the main parameter to measure the crane lifting capacity. Crane selection, considering not only from the weight, but also to consider the magnitude of the work. Namely: lifting weight lifting torque = X working range.② Lifting capac...
  • Basic classification of tower crane 2016/3/25 一. according to the working methods of classification: Fixed crane: tower does not move, the scope of work by rotation and trolley tower arm complete, used for high-rise buildings, structures, blast furnace installation works.
