Provided is a construction machine including a hydraulic system having a hydraulic pump, and a first hydraulic actuator and a second hydraulic actuator which are driven by hydraulic oil supplied from the hydraulic pump. The construction machine includes a first flow rate detector that detects a flow rate of drain hydraulic oil discharged from the first hydraulic actuator, a second flow rate detector that detects a flow rate of drain hydraulic oil discharged from the second hydraulic actuator, and an abnormality determination unit that determines abnormality of the first hydraulic actuator, based on a detection signal from the first flow rate detector, and determines abnormality of the second hydraulic actuator, based on a detection signal from the second flow rate detector. The first flow rate detector and the second flow rate detector each have a moving body.

The present disclosure relates to a method for real time monitoring of the current status of a construction site having one or more work machines, wherein a monitoring means installed at least one work machine monitors the environment of the work machine in real time and generates corresponding monitoring data, with the generated monitoring data being transmitted by the monitoring means to at least one processing unit for a real time evaluation of the current construction site status.

A load-leveling hanging apparatus and a system for suspended lifting of objects are disclosed. The load-leveling hanging apparatus includes a carriage suspended from a line; a hanging beam adapted for attachment of multiple objects at points along the beam; a mechanism for moving the hanging beam relative to the carriage to thereby achieve a level condition; and a level indicator. The mechanism is a rotatable screw. The system includes the load-leveling hanging apparatus and a lifting device. The lifting device includes a drum for winding and unwinding a line; a motor coupled to the drum to apply a torque thereto; a guide to direct the line onto the drum; and a controller. The lifting device raises and lowers the suspended hanging apparatus.

A system for a semiconductor fabrication facility includes a maintenance tool, a control unit, a first track, a second track, a maintenance crane movably mounted on the first track, a plurality of first sensors disposed on the first track, an OHT vehicle movably mounted on the second track, and a second sensor on the OHT vehicle. The first sensors detect a location of the maintenance crane and generate a first location data to the control unit. The second sensor generates a second location data to the control unit.

The present disclosure relates to a controlling system console and a controlling system. In the console, a central control component is connected to an electric hoist control device via network, enhancing transmission speed and stability of signals. The console can send a combination action control signal through a combination action control component, such that the central control component creates a combination action control instruction and sends the combination action control instruction to the electric hoist control cabinet to make the electric hoist perform combination actions. The console can further send a collaboration action control signal through a collaboration action control component, such that the central control component creates a collaboration action control instruction and sends the collaboration action control instruction to the electric hoist control cabinet to make the electric hoist to act in collaboration with other arena devices.
