ABSTRACT

Field performance of press-in piling greatly depends both on performance of machine and on operators’ experiences and skills. A questionnaire survey was conducted on the field performance of press-in piling machine, with the special attention to Gyro Piler. The paper firstly describes key maintenance items of the piling machine for effective piling operation provided by the manufacture. The items listed are a good indication of the parts of machine that may experience malfunction when operators use the machine in a way that mechanical design engineers do not expect. The paper secondly describes the objectives, the methods and results of the questionnaire survey. The survey concludes that operator’s experience and skill play an important role for effective press-in piling with a minimum risk for damaging the machine.
