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.

Provided is a wire diagnosis apparatus mounted on a lifting device, which has a platform having a hook disposed at a lower portion to lift an object. The wire diagnosis apparatus includes: a standing unit detachably combined with any one among an inlet and an outlet where a wire of the platform comes in and out; a sensing holder unit formed in a cylindrical shape perforated in the middle and detachably combined with a stand combining part of the standing unit to sense the wire; and a coupling unit detachably combining the sensing holder unit with the stand combining part of the standing unit.

A method and system for conducting a non-contact survey of an overhead crane runway system using a survey apparatus that is alternately located in the crane bay or on a crane bridge girder. Disclosed more particularly are a method and system for testing an overhead crane runway beam 3D alignment or an overhead crane runway rail 3D alignment using a 3D laser scanner.

Aspects of the disclosure relate to a mechanical fuse. The mechanical fuse may include a top portion having a first shear pin configured to break when a predetermined side load is applied to the mechanical fuse. The mechanical fuse may also include a bottom portion having a second shear pin, wherein the second shear pin is configured to break when a predetermined vertical load is applied to the mechanical fuse. Wherein the mechanical fuse may be arranged such that when the second shear pin is broken under the predetermined vertical load, the first shear pin also breaks before the bottom portion separates from the top portion, and when the first shear pin is broken under the predetermined side load, the second shear pin remains intact when the bottom portion separates from the top portion.

This invention relates to a pick and place gripper device and a method for picking up and re-positioning an item carried by a support surface. The gripper device includes a base, at least one jaw pivotally mounted to the base having at least one leading edge, at least one belt of flexible material being wrapped around at least the leading edge of the at least one jaw such that it is sandwiched between the at least one jaw and the item when the at least one jaw penetrates below the item and as the at least one jaw moves below the item there is substantially no relative sliding movement between the sandwiched portion of the at least one belt and the item, wherein the leading edge of the at least one jaw, when coming into contact with the support surface, is configured to adjust to the support surface when penetrating between the item and the support surface.

A rough terrain crane is equipped with dashboard cameras and digital cameras for capturing bird's-eye view image thereof. The equipment performs, when a load factor reaching 90%, a process of recording start for starting image data recording with the digital camera and a process of storing measurement value for recording a load factor concurrently with the process of recording start. The image data is recorded with the digital camera associated with the above activation condition, among the digital cameras installed in the rough terrain crane.
