| Abstract:With assembling and disassembling devices of quadrangular tube derrick on the ground, the assembling and disassembling can be completed on the ground. The installation is started from the derrick top, this first part is lifted a certain height by elevator, then the next begins. The work can be operated on the ground to avoid the unsafe factors to improve working efficiency and reduce installation cost. |
