There is provided a periphery display device for a work machine, which displays a bird's-eye view image around the work machine. A display magnification of a region between a peripheral line having a turning radius of the work machine and an offset peripheral line surrounding the peripheral line is different from a display magnification of a region inside the peripheral line.

Attachments for excavators and the like for improved gripping, handling, and processing of materials and debris are provided having one or more work surfaces to provide enhanced material handling characteristics.

The cab includes a front pillar on the first side face and a front pillar disposed on the second side face and located behind the front pillar. The cab includes a front transparent member located between the first side face and the second side face and a lateral transparent member provided the second side face and connected to the front pillar. The cab includes a roller disposed on the front transparent member and a bracket disposed on the lateral transparent member and provided with a rail member to guide the roller.

A device that includes a memory and a processor is disclosed. The processor may be configured to receive a control signal for operating a plurality of traction motors of a work machine. The control signal may include information relating to an actual speed of the work machine, a target speed of the work machine, and a generator speed of a generator operatively coupled to the traction motors. The processor may be configured to determine respective torque commands associated with the traction motors based on the actual speed and the target speed, and determine a generator power limit based on the generator speed. The processor may be configured to determine a threshold based on the respective torque commands and the generator power limit, adjust the respective torque commands based on the threshold, and cause the traction motors to be operated based on the adjusted respective torque commands.

A hollow first accommodating case (28) is provided on a front part of a revolving frame (5) at a position on a front side of a fuel tank (23), and a fuel supply pump (34) for supplying a fuel stored in an external fuel storage source to the fuel tank (23) is provided on the fuel tank (23) by being connected. A fuel suction port (35) for sucking the fuel toward the fuel supply pump (34) is provided in the first accommodating case (28) by being opened to an outside, and a urea water tank (25) is provided by being accommodated in the first accommodating case (28). A water supply port (25G) of a urea water is provided in the urea water tank (25) by being opened to the outside, and the fuel suction port (35) and the water supply port (25G) of the urea water are juxtaposed and arranged in the first accommodating case (28).

A BEIM (Built Environment Information Model)-based control system (CS) for controlling an earthmoving machine (E) is disclosed. The control system includes at least one controller (CO) for controlling at least one movement of an earthmoving tool (3) attached to the earthmoving machine, at least one control unit (CU), and sensing means (11, 12) for providing the control unit with position data of the earthmoving tool and a carrier (1) of the earthmoving machine with respect to the BEIM. The control system also includes at least one displaying means for displaying at least one BEIM selectable by the at least one controller. An earthmoving machine and a method for controlling an earthmoving machine are also disclosed.

In a valve device, travel control valve unit has a communication path causing the lead-out passages of the left and right travel control valve units to communicate with each other, and a spool has a lead-out side land portion configured to cause communication or shut-off of the communication between the lead-out passage and the communication path, a discharge-side land portion configured to cause communication or shut-off of the communication between the actuator passage and the discharge passage, a discharge portion configured to discharge a part of the working fluid led from the supply passage to the lead-out passage to the discharge passage at a movement initial stage of the spool, and a communication portion configured to cause the lead-out passage and the communication path to communicate with each other at a movement final stage of the spool.
