The invention relates to the technical field of engineering machines and discloses an engineering machine and a linkage table thereof. The linkage table of the engineering machine comprises a linkage control module and further comprises a sensor, a signal processing module and a master switch signal effectiveness judging module, wherein the linkage control module is used for generating master switch signals and is provided with an operation handle; the sensor is located on the operation handle and used for collecting induction signals on the operation handle; the signal processing module is connected with the sensor and used for judging that the induction signals collected by the sensor are effective signals only when an operator holds the operation handle by hand and a determination signal is output; and the master switch signal effectiveness judging module is in signal connection with the signal processing module and the linkage control module and used for judging that the master switch signals of the linkage control module are effective when the determination signal is received and judgig that the master switch signals of the linkage control module are not effective when the determination signal is not received. During normal operation, the operator only needs to hold the operation handle, no extra operation is needed, and therefore the linkage table of the engineering machine can lower the operation strength of the operator.
