Q:How much is a team of 40 tower crane
Tower crane rental generally do not rent pricing, can not count number, not today is installed, removed tomorrow!Usually on a monthly basis, with or without use!
Q:All types of jack up cranes. How is the maximum lifting torque converted?
Tower crane lifting torque = crane maximum lifting weight * maximum operating range; for example: the maximum lifting weight is 2T*, the maximum operating range of 50 meters =1000KN.m.
Q:What tower cranes are used on the 30 storey house?
but if the building steel structure more parts or building the number of square meters more than 60 thousand square meters, you need to consider QTZ80 or more of the tower crane, because the type of large lifting capacity is big, the work efficiency is high. Hope to be of help to you!
Q:Tower crane demolition safety technical disclosure, how to write?
