A storage part of a construction machine stores an operation target which is set as a target of an operation of the construction machine for moving a specific portion of the construction machine to a target position set as a destination to which the specific portion moves. A calculation part calculates an index value which serves as an index indicating a deviation between the operation target and an actual state of the construction machine. A control device is configured to cause a vibration applying device to perform a first vibration applying operation when the index value satisfies a predetermined first condition, and to cause the vibration applying device to perform a second vibration applying operation when the index value satisfies a predetermined second condition different from the first condition.

Construction machine

A dismantling system includes a dismantling machine including a tip attachment for dismantling an object to be dismantled, an imaging device that provides a field of view from a second viewpoint position for visually recognizing an object to be dismantled, which is different from a first viewpoint position of an operator, and a dismantling operation device that receives operation by an operator of the tip attachment for dismantling an object to be dismantled with respect to the field of view provided by the imaging device.

Dismantling system

The construction machine includes: an input interface which permits an input of a provisional target position of the attachment in a virtual space; a target position calculation part which calculates an actual target position that is a target position of the attachment in a real space from the provisional target position; an operational amount calculation part which calculates an operational amount required to make a current position of the attachment coincide with the actual target position of the attachment coincide with the actual target position with respect to at least one driven target selected from a lower traveling body, an upper slewing body, a working device, and the attachment; and a control part which controls an operation of one of the actuators for driving the driven target in accordance with the calculated target operational amount.

The present small swing type excavator is characterized by comprising an engine () disposed in the rear section of a rotating frame () in such a condition that the longitudinal direction thereof is directed to the lateral direction of the rotating frame (), a hydraulic oil tank () disposed on one lateral side in front of the engine (), a cabin () disposed on the other lateral side, an air conditioner () disposed under a floor () of the cabin () and having two surfaces facing to, respectively, the front side and the left outer side of the rotating frame (), and a fuel tank () formed so as to be arranged along at least two surfaces of the front and left side surfaces of the air conditioner () and detachably attached to the rotating frame ().

Small swing type shovel

In a construction machine having a working attachment, an operator's seat disposed on one side of a machine body, a devices receptacle portion disposed on the other side, and an operating member disposed sideways of the seat for operating the attachment, the machine is characterized in that a canopy comprises a front support post disposed in front of the seat, a rear support post disposed behind the seat, a side support post disposed sideways of the seat and on the side where an operator gets on and off the machine body, and a roof which connects the support posts with one another, the front support post being disposed close to the devices receptacle portion and the side support post being disposed outside the operating member to form an open portion obliquely in front of the seat where open portion is for ensuring a working vision for the attachment which is swung to the seat side.
