A pneumatic torque impulse delivering power tool (10) with an automatic power shut-off mechanism, the power tool (10) comprising a pneumatic motor (11); a drive member (16) which is driven to rotate by said pneumatic motor (11); an air supply channel (14) for providing the motor (11) with pressurized air; a shut-off valve (15) arranged in said air supply channel; and a valve control device (17) arranged to shut said shut-off valve (15) and stop the air flow to the pneumatic motor (11) when the drive member (16) is exposed to a retardation magnitude above a certain threshold level. The valve control device (17) comprises an inertia responsive member (18), which is arranged to rotate along with the drive member (16), and which is pivotally arranged with respect to the drive member (16) between an initial position in which it does not interfere with the shut-off valve (15) and a shut-off position in which it allows the shut-off valve (15) to close. The valve control device (17) further comprises an air damped movement restrictor (29) arranged to counteract the movement of the inertia responsive member (18) towards its shut-off position, such that the shut-off valve (15) is only shut when the drive member (16) is exposed to a retardation magnitude above a certain threshold level corresponding to a dampening force of the air damped movement restrictor (29). A spring (35) may be arranged inside the air damped movement restrictor (29).

The overall concept of MANTIS is to provide a proactive maintenance service platform architecture based on Cyber Physical Systems that allows to estimate future performance, to predict and prevent imminent failures and to schedule proactive maintenance. Maintenance is no longer a necessary evil that costs what it costs, but an important function that creates additional value in the business process as well as new business models with a stronger service orientation. Physical systems (e.g. industrial machines, vehicles, renewable energy assets) and the environment they operate in, are monitored continuously by a broad and diverse range of intelligent sensors, resulting in massive amounts of data that characterise the usage history, operational condition, location, movement and other physical properties of those systems. These systems form part of a larger network of heterogeneous and collaborative systems (e.g. vehicle fleets or photovoltaic and windmill parks) connected via robust communication mechanisms able to operate in challenging environments. MANTIS consists of distributed processing chains that efficiently transform raw data into knowledge while minimising the need for bandwidth. Sophisticated distributed sensing and decision making functions are performed at different levels in a collaborative way, ranging from local nodes to locally optimise performance, bandwidth and maintenance; to cloud-based platforms that integrate information from diverse systems and execute distributed processing and analytics algorithms for global decision making. The research addressed in MANTIS will contribute to companies assets availability, competitiveness, growth and sustainability. Use cases will be the testing ground for the innovative functionalities of the proactive maintenance service platform architecture and for its future exploitation in the industrial world. Results of MANTIS can be utilised directly in several industry areas and different fields of maintenanance.
